| Annotation: | From a broader perspective the Superconducting spintronics is vastly expanding field that strives to utilize spintronics phenomena and transfer its applications into the realm of superconductivity. While the latter can support dissipation-less charge transport, and also topologically protected (e.g. Majorana) modes, the former can make use of electron spin for encoding and processing information. For these reasons, one may hope to launch a spin-driven superconducting device that would be, on one hand, very efficient in terms of energy demands, and on the other hand, would offer computational functionalities operating on quantum principles. The beauty of the above idea rests in its simplicity, but as always, devil is hidden in details. To bring such spintronics vision into an operating platform one would need superconducting materials that promote unconventional pairing of electrons into Cooper pairs. Unfortunately, Nature does not give us “free of charge” unconventional superconductors with all those wonderful properties. However, it offers us, instead, “smaller pieces of material-lego” that when being proximitized along each other engender the “scaffolded synthetic hybrid systems” owning effective unconventional pairing (and even much more). Such proximity effects, which are central to my proposal, represent a versatile platform to 1) control and functionalize spin, orbital, topological and magnetic properties of the constituting subsystems by external means – gating, temperature gradients, chemical composition, band structure engineering etc.; and 2) synthetize quasi-2D interfaces promoting an unconventional superconducting pairing and them associated topological bound states (Majoranas, Yu-Shiba-Rusinov states, Caroli-de Gennes-Matricon vortex states, etc.). From the specific point of views, my research ambitions within this programme count particularly two scientific projects: (A) Spin relaxation phenomena in low-dimensional (un)conventional superconductors, and (B) Topological states engineered through proximity effect – superconductivity on the edge. |

| Annotation: | Solar cells (SCs) are one of the highly promising options for environmentally clean electricity production. Their role in our future energy mix depends on further reduction in system costs, and device efficiency is of key importance. Hybrid organic-inorganic perovskites seem to be suitable candidates for next-generation photovoltaics, either in tandem with crystalline silicon solar cells or as a cheap/flexible thin-film alternative. Over the last few years, the power conversion efficiency of perovskite SCs has surpassed 25 %. However, its further increase is conditioned by the effective passivation of the detrimental defects at the perovskite interface and grain boundaries. This project is dedicated to understanding the role of defects in limiting photovoltaic performance and developing effective passivation routes to achieve further performance advances. Its innovation potential lies in increasing the efficiency of future SCs via targeting the defect-related nonradiative traps at the surfaces and interfaces and their efficient passivation. The project combines the different expertise and various experimental techniques of three partners intending to translate the acquired new scientific knowledge of defect passivation in hybrid perovskites into technological advances. |

| Annotation: | The presented project will deal with the free-volume properties of polymer networks cured by new processes and their consequences on some physical properties, especially thermal properties around the glass transition and material properties. Polymers that are used in many applications based on dimethacrylates and epoxides will be investigated. They will be cured by a common and controlled polymerization as well as by the frontal polymerization. From the lifetime of the external positronium probe, the sizes of the inter-molecular free volumes will be determined and the changes in local free volumes during the curing processes as well as their dependences on the external parameters (temperature) will be examinated. Differences in the microstructure of polymers prepared in different ways will be determined, both in bulk and in the confined conditions of macro- and mesopores. Processes leading to different microstructural inhomogeneities of polymers will be investigated as a consequence of both the different crosslinking mechanisms of materials studied and the external conditions. The obtained free-volume characteristics will be compared with the results of other characterization techniques (FTIR, NIR, DSC, SEM, photo-rheometry, dielectric spectroscopy). The physical bonds will be studied which influence the properties of the polymer network in both bulk and confined states. |

| Annotation: | The presented project includes basic research in the field of particulate micro- and mesoporous carbon-based materials (PCM) with significant application impacts. It represents an original approach to the development of a method for the preparation of several types of PCM with significant sorption properties and a wide application potential. To optimize their use it is necessary to know in detail their physical properties (microstructure and porosity) and find a connection between the conditions during the formation of PCM (carbonization) and resulting microstructure, which is the first intention of the project. The originality lies in the combination of different physical methods of studying PCM, using standard sophisticated techniques (electron microscopy) as well as non-standard methods such as positron annihilation spectroscopy, thermoporosimetry and gamma spectrometry. Another purpose is to find procedures for the appropriate modification of PCM and elaboration of composites for several applications. |

Since the DOS determines the optoelectronic properties, itsunderstanding and design are essential for all applications. The electronic structure will be investigated using theelectrochemical methods developed by our research team. Changes in the microstructure will be controlled by thechoice of a solvent and annealing conditions. Susceptibility to degradation in the air will be investigated as well.Our planned research will be based on the combined use of experimental, theoretical, and computationalapproaches. We will use the density-functional theory (DFT), the related DF tight-binding (DFTB) method and thetime-dependent DFT as theoretical bases for our calculations of the electronic structure.

| Annotation: | The project aims to simulate quantum systems to understand the mechanisms of quantum entanglement concerning the interactions among particles (electrons/spins and photons) that are exposed to various external fields, typically magnetic ones. In specific cases, quantum correlations may suddenly amplify, which is reflected in macroscopic quantities. In theory, they behave non-analytically, while in the experiment, maxima (minima) or sudden jump changes are observed. Our task is to numerically simulate these processes and classify them by entanglement entropy. Simulations combine theory with experimental measurements. While in theory, we can solve only a small number of problems exactly, numerical simulations can cover a relatively large area of non-trivial problems. In this project, we will explore new quantum systems using state-of-the-art numerical methods, which we will formulate and implement. We will design conditions for devices under which it will be possible to perform experimental measurements. |

| Annotation: | Nuclear deformation may occur in a any atomic nucleus and it appears that it is the single most-important feature of nuclear structure. The most spectacular example of such organization in nuclei is the highly deformed Hoyle state in 12C through which carbon is produced in the Universe. The proposed project aims to elucidate the underlying nuclear structure that is responsible for appearance of such deformed configurations. The goal of the present project is to provide key new experimental data for various isotopes. Experiments will be performed at the University of Jyvaskyla (Finland) and at newly established Tandetron Laboratory in Piestany. In Jyvaskyla, isotopes 179,191,192Bi will be studied by means of isomer and in-beam gamma-ray spectroscopy. For the isomer spectroscopy, significantly modified setup will be employed at the focal plane of the recoil separator. In comparison with conventional methods, it will allow to increase the beam current by a factor of at least 10. Therefore, it has potential to establish new research areas, that might be interesting also for different groups. A multiwired proportional chamber will be developed and delivered to Jyvaskyla for this purpose. New spectrometer, based on liquid nitrogen cooled Si(Li) detector, will be constructed for the laboratory in Piestany. It will be used for the conversion-electron spectroscopy. This technique is very difficult and therefore is pursued by only very few groups in the world. It will be used for measurement of electromagnetic properties of ground-state and first-excited state of 59,61Cu isotopes. |

| Annotation: | The growing global demand for electricity makes it essential to develop alternatives to fossil fuels. Not only to divert the upcoming energy supply shortage but also to reduce the effects of climate change. In this perspective, renewable energies from inexhaustible natural sources are the key to this industry\'s future, and solar energy, in particular, is one of the most promising. Solar cells (SCs) are one of the up-and-coming options for environmentally clean electricity production. Among several state-of-the-art generations, perovskite SCs, with the perovskite active light-harvesting material, are currently the most encouraging and promising hotspots of research. In order to make perovskite-based SCs available in the future, several issues need to be resolved, such as their lower efficiency compared to the most commonly used silicon. It was found that charge recombination plays a significant role in restricting the performance of potential perovskite-based applications, which usually happens in the presence of defect states. It is generally accepted that the perovskite defects are responsible for most of the issues that hinder the further commercial usage of perovskite-based devices. This indicates that the direction of further efficiency increase lies in the addressed defects passivation. Therefore, this project focuses on a detailed investigation of defect-induced nonradiative recombination processes in perovskite films and subsequent passivation of the defect states. |

| Annotation: | With the steadily increasing energy requirements of portable electronics and electromobility, conventional lithiumion batteries are facing new challenges. In the proposed project, we aim to stabilize the capacity and lifetime oflithium-ion batteries employing ultra-thin interfacial layers prepared by means of atomic layer deposition (ALD). Theprimary functions of interfacial layers are: i) preventing the dissolution of the cathode materials into electrolyte andii) stabilizing the cathode morphology during lithiation and de-lithiation. Although the positive effect of ALDfabricated interfacial layers has already been demonstrated, systematic studies are still missing. The mainbottleneck of such studies is the identification of appropriate feedback analytical techniques that enable real-timeand in-operando insights into the charging/discharging mechanisms on the nanoscale. The conventionalelectrochemical characterization methods can only provide hints on the ongoing mechanism during degradationprocesses. Here we propose to utilize in-operando small-angle and wide-angle X-ray scattering (SAXS, WAXS) totrack the morphology and phase changes that occur during the charging/discharging of lithium-ion batteries in realtime. The main focus of this project is on the application of real-time SAXS/WAXS studies under laboratoryconditions. In these circumstances, extensive, systematic studies of various ALD interfacial layers can beperformed. |

| Annotation: | Pancreatic cancer is a lethal disease with a rising incidence and mortality and it is the fourth leading cause ofcancer-related deaths in Europe. The median survival time of pancreatic cancer is 4-6 months after diagnosis, thelowest survival rate of all cancers. Only 20% of diagnosed cases are operable. Photothermal therapy (PTT) has thepotential to become a new frontrunner in the fight against pancreatic cancer. This cutting-edge biomedicalapplication relies on the rapid heating of the plasmonic nanoparticles induced by laser light absorption, followed byan increase in the ambient temperature around the nanoparticles. The effect of the localized surface plasmonresonance (LSPR) can be observed only in a special class of nanoparticles. Photothermal therapy results inselective hyperthermia and irreversible damage of the tumor while avoiding damage to healthy tissue.However, the delivery efficiency of plasmonic nanoparticles is often insufficient. It can be increased by a dedicated functionalization of the plasmonic nanoparticles with ligands (antibodies) that selectively recognize the cancer cells.One of the main aims of the proposed project is to increase the delivery efficiency of the plasmonic nanoparticlesfor PTT by functionalization with antibodies that selectively recognize the tumor in the body. A promising target forfunctionalized nanoparticles is carbonic anhydrase IX, a hypoxia biomarker associated with an aggressivephenotype. CA IX is expressed in many types of tumors, while being absent from adjacent healthy tissue, making itan ideal highly specific candidate for anti-cancer therapy target. CAIX is abundantly expressed on the surface ofpancreatic cancer cells where it correlates with a poor patient outcome. Targeting pancreatic cancer viananomaterials-based approach combined with anti-CAIX antibody ensures highly selective application of PTT withpotential benefits in the clinical environment. |

| Annotation: | Many aspects of quantum measurements are conceptually puzzling. However, their practical implementation is of interest for current development of quantum technologies. Interestingly, it is also a theoretical challenge to develop novel tools and efficiently design desired quantum measurements. The canonical implementations are often very complex and possible only in theory. The goal of this project is to investigate and design measurements in three different conceptual frameworks - system of cloud universal quantum computers, thermodynamic machines, and superconducting qubits. We will develop novel simulations of existing physical systems to learn about their ability to accomplish the considered quantum measurements. As a result, we expect realistic proposals for new quantum measuring apparatuses, tools for implementing complex quantum observables efficiently also on existing quantum infrastructures, and specification of certifiable requirements that such infrastructure should meet. |

| Annotation: | We deal with particles diffusing in non homogeneous quasi-one dimensional systems (nanochannels, pores),driven by external forces or chemical reactions. We study effects which can appear in such systems, like anomalous behavior of mobility, diffusivity, or rectification of particle flow, the ratchet effect. These effects are basic for description of particle separators, Brownian pumps, or molecular motors in nano- and biophysics. We use our new method of dimensional reduction of a 2D/3D advection -diffusion equation (Fokker-Planck in general)onto the longitudinal coordinate of the channel, including correctly the forces, as well as nontrivial boundary conditions at the channel walls. The result is the generalized Fick-Jacobs equation, enabling us to calculate the key physical quantities in a straightforward way, e.g. mobility, diffusivity, mean transition times, etc. The project involves development of the method of dimensional reduction, extension to more complicated systems, as well as its applications. |

| Annotation: | Perovskite solar cells (PSCs) revealed impressive progress in power conversion efficiency (PCE) from 9 % up to25% during the last 10 years. PSCs are multilayers, where the active perovskite layer is placed between thelayers for selective charge transport to electrodes. Structure, morphology and transport properties of the layersand interfaces determine the performance of PSCs. Application of 2D nanomaterials in PSCs offer a possibility tomodify the performance. Better energy levels alignment of layers, the improved crystalline structure of theperovskites and increased stability of the device are possible benefits. This project is focused on complex studiesof the effect of incorporation of 2D MXenes in the electron transport layer and in the perovskite layer. PSCs withdifferent types of perovskites will be studied. This research will be completed by a detailed analysis of theMXenes/ perovskite interaction. For this aim, we will develop and analyze a bilayer MXenes monolayer/perovskite. |

| Annotation: | Currently, the issue of reducing energy consumption in all phases of the life cycle of buildings is coming to the fore more intensively. The sustainability and energy efficiency of buildings is assessed not only on the basis of thermal insulation properties, but also on the basis of the demand for primary energy, the reduction of CO2 emissions and the environmental properties of the materials used. In this context, the use of recyclable and nature-friendly materials such as e.g. wood biocomposites, technical textiles, sheep\'s wool, etc. Their use reduces the environmental burden. When designing buildings, not only the thermophysical properties of materials are important, but also fire and acoustic properties. The results of the project solution can be a guide for production practice in the search for a suitable combination of insulating materials. Another result will be a database of thermal insulation, acoustic and fireproof properties of materials created in such a way that the data are comparable with each other (measurement of the same properties using the same methods). |

| Annotation: | The project is focused on the research and development of new types of X-ray optics with highly accurate curvedactive surfaces. The surfaces will be prepared by an innovative nanomachining technology. We will investigatethe application of nanomachining technology to a special case of X-ray optics with curved surfaces, which is aparabolic refractive lens operating in the transmission geometry. The second special case we will focus on will bethin crystal monochromators with different thicknesses in a range of 20-2000 micrometers. Such elements can beused for example as beam splitters in modern X-ray free-electron lasers (XFEL), bent crystals in Johanssonmonochromators for spectroscopic applications, or they can also be used in particle accelerators for beamsteering. The developed elements of curved X-ray optics will be tested in real X-ray metrology and X-ray imagingexperiments using laboratory or synchrotron X-ray sources and highly sensitive directly converting X-raydetectors Pilatus and Medipix. |

| Annotation: | Introducing small molecular semiconductors as additional building blocks into heterostructures of 2D materialswidens the applicatory potential of both systems – the organic semiconductors, as well as the 2D materials.Organic molecules can form self-assembled crystalline nanostructures on 2D substrates, resulting in well-definedinterfaces that preserve the intrinsic properties of both constituents. These structures, combining the organicmolecules with 2D inorganic layers, form so-called hybrid van der Waals heterostructures (vdWHs), promising moreexciting applications such as flexible or bio-compatible electronics. This project is focused on the investigation ofthe hybrid vdWHs with great potential in organic (opto)electronics. In more detail, we will take advantage of thewell-established molecular beam deposition technique for the growth of thin semiconducting layers consisting ofsmall organic molecules on the 2D inorganic layers. We will concentrate on the growth kinetics, molecularorientation, crystallographic structure and parameters of the organic films on 2D substrates. Furthermore, theorganic films will be utilized as an essential ground for the development and study of perovskite-basedheterostructures (exploit in solar cells). |

| Annotation: | This project is devoted to our continuous effort aimed at the diabetes treatment by transplanted insulin-producingcells that are immunoprotected from the host immune system by a semipermeable polymer membrane. Thismembrane is in the form of a hydrogel microcapsule formed by the polyelectrolyte complexation of polyanions,the sodium alginate (SA) and sodium cellulose sulfate (SCS) with the polycation poly(methylene-co-cyanoguanidine), (PMCG). Over the past two decades we have accumulated important knowledge showing thatthis type of microcapsule (acronym PMCG), belongs to the family of microcapsules with a promise to reach thephase of clinical trials. There are two principal advantages of this microcapsule: (1) it exhibits biocompatibilityafter intraperitoneal implantation to various animal models, including the pre-clinical model of non-humanprimates (NHP), (2) it affords a unique ability to tailor the physico-chemical properties in correlation with in vivoperformance that is not possible for other encapsulation systems. The MICROPAN project aims at the firstsystematic investigation for the microencapsulation system of the correlation between polymer selection, encapsulation conditions, microcapsule properties and in vivo performance. This is thanks to the availability of in-house synthesized SCS and PMCG polymers used instead of commercial polymers with inconsistentcharacteristics. The expected project outcome will be the library of microcapsules of predicted performance invivo in the immunocompetent mice with the proposal to test selected microcapsules in NHPs that will be plannedoutside of MICROPAN project. This project will enhance our understanding of the mechanism of microcapsuleformation by polyelectrolyte complexation and, hence, will contribute to the future rational designs ofmicrocapsules for immunoprotection of transplanted cells. |

| Annotation: | Future quantum technologies are aiming to enhance our computational power, secure our communication, but also increase precision of our detection devices (from detectors of gravitational waves to medicine diagnostics methods). The effort of researchers included in this project is focused on optimisation of theoretical proposals, also by taking into account more realistic models reflecting the situations outside the laboratories. Our project joins the second quantum revolution on the side of theory, while aiming at mid-term quantum technology applications. We will develop novel tools and methods for improving the performance of quantum measurement, simulation and optimization devices. In particular, we aim to investigate the mathematical structure of quantum information resources in order to utilize them in novel and efficient quantum metrology applications and quantum simulations. The planned analysis of higher-order quantum structures and related optimal information processing is uncovering new quantum resouces (e.g. quantum causality, memory) that has potential to boost qualitatively the performance of quantum computation and communication technologies. Our plans to optimize tensor network algorithms by using the structure of interactions (space-time) are definitely enlarging our chances for efficient quantum simulations of physically relevant quantum many-body systems. Project tasks are divided into three workpackages aiming to optimize quantum structures, develop optimal higher-order quantum information processing and optimisation of tensor network algorithms. |

| Annotation: | Clinical studies have identified hundreds of different volatile organic compounds (VOCs) present in exhaled air of a human at concentrations in the order of ppm (10-6) or only ppb (10-9) and lower. Some VOCs are recognized as bio-markers of metabolic and physiological processes and potentially allow non-invasive health examination.For example, a healthy person has concentration of acetone vapors < 0.7 ppm, >1.7 ppm indicates a diabetes patients [1]. A sub-ppm acetone vapours sensor would allow the construction of a personal tester.The focus of the project will be a research of tungsten trioxide layers for a chemoresistive acetone sensor operating at hundred ppb. We will focus on the triclinic crystallographic phase of WO3, in which a high response to acetone adsorption has been observed. We will develop the preparation of the WO3 nanocrystalline layers with the maximum triclinic phase content, and study its effect on the sensory response and explore other WO3-based systems to increase sensing response. |

All experiments will be backed up by computer simulations using mainly methods of density functionaltheory and, for correlated systems, by correlated electronic structure methods, QMC in particular. In order toachieve these objectives we will use the well-proven international consortium which in the last 5 years hasgenerated several top results published in journals with highest impact factors (Nat. Phys., Nat. Commun., NanoLett., ACS Nano, J. Am. Chem. Soc.).

Scientific objectives will be complemented by 4) Educational and public outreach targeting younggeneration. Objective of the current AFM-IMASS project will be top internationally competitive results with theambition of publishing them in the journals with highest impact factors- part of the results in journals with impactfactors >10. |

| Annotation: | The van der Waals heterostructures (vdWHs) are newly discovered physical structures that consist of severaltwo-dimensional (2D) atomic layers held together by weak van der Waals forces. The vdWHs show uniquefunctionalities that are not accessible in their three-dimensional counterparts. This project is focused on theinvestigation of the hybrid vdWHs (hybrid refers to the fact that at least one of the layers is organic) with largeapplication potential in organic electronics and optoelectronics. In particular, we will investigate the growthkinetics, molecular orientation, structure and lattice parameters of organic thin films deposited on 2D substrates.The proposed research will address fundamental questions of the molecular thin film growth processes withparticular emphasis on time-resolved in-situ experiments. The novelty of this project resides in the use of newand intriguing 2D materials as the substrates for the growth of organic molecular films and in a detailedinvestigation of this growth process in order to tailor preparation of novel hybrid vdWHs with specific properties.We will use 2D substrates with different electronic properties, namely the semimetal graphene and thesemiconducting MoS2 thin films, which both have strong application potential in nowadays electronics.Regarding the organic molecules, we will concentrate on those possessing the properties beneficial foroptoelectronics, such as absorption in the visible spectrum range, good electric conductivity and capability of self-assembly. We will start with pentacene and TzTz-based small molecules. We believe that such basicresearch is highly relevant for further development of enhanced organic electronic applications such as organiclight emitting diodes, organic field effect transistors and organic solar cells. |

| Annotation: | Metal halide perovskites are an exciting class of materials that possess many of the attributes desirable for optoelectronic applications, with certified power-conversion efficiencies of perovskite-based photovoltaics reaching 23%. Photoluminescence quantum efficiency of thin films used in highly efficient devices is still low (~1%), which is mainly consistent with sizable density of sub-gap trap states that act as non-radiative recombination centers. In order for a solar cell to reach its theoretical performance limits, luminescence should be maximized with all non-radiative recombination eliminated. The conventional perovskite films prepared by solution process are usually composed of nanoscale grains so that there are a number of boundaries in the film. Correspondingly, a perovskite monolayer with single crystal cross-section profile is considered to be the desired active layer. The characteristics of the monolayer film are very close to that of the single crystal film. However, how to prepare a monolayer perovskites film with single crystal cross-section profile for solar cells is still a big challenge. The primary project’s objective is to identify the key mechanisms governing the formation of perovskite thin films during solution fabrication process. Accordingly, systematic understanding of perovskite crystals growth process is highly required and will be sorted out by real-time and in-situ GI-WAXS/SAXS complemented by real-time photoluminescence. The ex-situ energy-resolved electrochemical impedance spectroscopy of trap states in bandgap will be employed to elucidate the relationship between the electronic and structural properties of perovskite thin films. The principal aims of this joint research proposal are focused on understanding of growth mechanism of the perovskites, which will enable controllable fabrication of perovskite monolayer films for high efficiency solar cells. |

| Annotation: | The project addresses research and development of a new generation of channel-cut X-ray monochromators with added functionality of the beam conditioning for X-ray metrology and X-ray imaging (geometry, monochromatization degree, collimation and coherence) and in this regard further implementation of SPDT (single point diamond technology) nanomachining for preparation of active surfaces of crystal X-ray optics. The parameters of SPDT and Ge surface finishing on nanomachining will be optimized and after testing on open surfaces, the optimized procedures will be applied to preparation of innovative monolithic V-shaped channel-cut X-ray monochromators for the beam compression (X-ray metrology) and expansion (X-ray imaging). Simulation algorithms based on the dynamical theory of X-ray diffraction for tailored monochromator design with pre-defined properties will be developed. The prepared monochromators will be tested in real experiments of X-ray metrology and X-ray imaging. |

| Annotation: | Latest results measured on the collider BEPC-II with very intensive beams of electrons and positrons allows to extract the information on the electromagnetic structure of nucleons that is in good agreement with other experiments. BEPC-II also allows for the first time to elaborate separate measurements of electric and magnetic structure of baryons in time-like region. It seems essential to have the model which predicts the behavior of the parameters characterizing these structures of baryons. The project aims to implement theoretical predictions in the framework of our elaborated model. Related issue is the evaluation of observables for the decay of heavy mesons in the framework of covariant quark model, which are the subject of interest for a research at today\'s accelerators. |

| Annotation: | The performance of electronic devices made of graphene substantially depends on the interactions of graphenewith a substrate beneath, mostly silicon substrate covered with oxide layer. The reasons are numerous: remotephonon scattering, charge traps, adsorbed dopants, etc. Recently it was proven that changing silicon to diamondsubstrate significantly improved performance of the graphene devices. However, theoretical calculations ofinteractions at the graphene – diamond (GOD) interface vary and often contradict each other. Systematicexperimental studies related to the nature of GOD interactions are missing. In our project we proposeexperimentally to realize systems of graphene-on-diamond by different routes that will result in different GODinterfaces. We will investigate the atomic and electronic structures using HRTEM/STEM with atomic resolution,and perform other complementary characterizations. We will also produce GOD field effect devices and willrelate the transport properties to the resolved structure at the GOD interface. The final goal is to understand theinteractions between graphene and diamond and their relation to electronic transport. |

| Annotation: | The efficiency of sunlight conversion to electricity relies, among other things, on the charge separation after the photovoltaic process initiation by the absorption of a photon which generates an exciton. The presence of a donor-acceptor interface in the thin films confines the electron and hole in their respective layers and facilitate thus the charge separation. In past years, the synthesis of novel all-conjugated copolymers bringing together hole- and electron-conductive polymers turned up to be of utmost importance. The relations between microstructure and electrical properties of such copolymers are far from being clearly understood. This originates from the presence of both the ordered (polycrystalline) and disordered (amorphous) phases in the solution-processed thin films. This project proposal is focused on the explanation of the relations between the microstructure of copolymer thin films and the structural defect-related DOS, which markedly influences the functionality of solar cells. |

| Annotation: | The project concerns the theoretical investigation of the ground state and low-temperature thermodynamics for systems of classical particles with Coulomb interaction. We shall study the phase transitions, critical exponents and the tricritical behavior of Wigner mono- and bi-layers which minimize the energy for the case of dimers of equivalent charges and dipoles of opposite charges. We shall derive the effective interaction between two equivalent macromolecules immersed in water. We shall study the effect of their charged surfaces on the space distribution of released micro-ions to describe a paradoxical attraction of the same charges based on the WIgner picture. We shall establish a theory to describe the low-temperature thermodynamics of micro-ions with a finite hard core. We shall try to construct a universal theory which interpolates correctly between the high-temperature Poisson-Boltzmann approach and the low-temperature Wigner description, respecting at the same time the contact theorem. |

| Annotation: | The goal of the proposed project is to develop a novel smart 2-dimensional multifunctional nanoplatform basedon MoS2 for cancer cell detection and treatment. The MoS2 nanosheets prepared by liquid phase exfoliationand/or Li intercalation and modified for low toxicity and high biocompatibility will be chemically functionalized withantibodies sensitive to specific cancer cells and relevant cytotoxine. In comparison to graphene basednanosheets the MoS2 provides much stronger signal for the advanced laboratory diagnostics such as Ramanspectroscopy, X-ray methods, SEM and TEM. Strong Raman signal and photoluminescence of MoS2nanosheets will allow a label-free in situ tracking of the nanoplatform localization at the cell level. This will be oneof the original project contributions to the knowledge of the cell interaction with the functional nanoplatform ingeneral. The new quality of the laboratory testing of the nanoplatform interaction with the cancer cells may bringnew knowledge and essential progress in the field of 2D nanoplatform generally. New knowledge is expectedalso in terms of a smart handling of biocompatibility and toxicity of the nanoplatform which is important for thenanoplatform cell internalization. Newly elaborated technological procedures will have direct implications fortailored 2D materials technology. |

| Annotation: | Proposed project deals with the complex research of corrosionprocesses on advanced construction materials that take place in aggressive molten fluoride salts. Research objects are special alloys and ceramic materials for high temperature applications prepared by different methods and consequently thermally threated. The study of the corrosion induced microstructure degradation is a key part of the project. The main objective is to understand corrosion damage of microstructure of construction materials in molten salts using multidisciplinary combination of techniques. Based on these techniques it is possible to analyse and characterise also very gentle changes in local structure of corrosion interlayers on atomic level between molten medium and material at elevated temperatures. Complex information on physical nature of particular molten systems is in centre of interest, as well. The combination of diffraction, imaging and spectral methods in combination with theoretical calculation enable us to determine structural characteristics of new phases formed in the corrosionprocess. Evaluation of the processes that take place will provide permanent share in studied field. This share can be even generalised and applied in many other fields. |

| Annotation: | Two-dimensional (2D) materials have been one of the most extensively studied classes of materials due to theirunusual physical properties. The best example is graphene – a single layer of carbon atoms arranged in a twodimensional (2D) honeycomb lattice. Many graphene´s extraordinary properties have been reported includingexcellent electronic and thermal conductivities and mechanical properties.Its discovery has also stimulated an extensive research on other 2D materials. It has been shown that it is notonly possible to exfoliate stable, single-atom thick 2D materials, but that these materials can exhibit unique andfascinating physical properties. The 2D structure determines the electronic properties that may exhibit correlatedelectronic phenomena such as charge density waves and superconductivity.In this project, we focus on preparation of ultrathin (< 10 nm) films and monolayers of materials from the family oftransition metal dichalcogenides (TMDs). The goal is to prepare those layers on a centimetre-large scale. Forthat, pulsed laser deposition and magnetron sputtering are the methods of our choice. As-prepared layers willthen be thoroughly characterised in terms of their thickness, crystallinity, homogeneity, optical and electricalproperties. As a next logical step, we will proceed in preparation of heterostructures and hybrids – systemswhere different TMDs materials and TMDs and graphene or graphene oxide are stacked on top of each other,respectively. |

One of the aims of the proposed project will be investigation of chemical reactivity and catalytic properties of surfaces of intermetallic transition-metal based alloys (Ni, Pd, Cu, ...) and nanoporous Au. Important new aspect of the project lies in development and application of special techniques of thermal processing in high magnetic fields for targeted modification of properties of new materials. |

| Annotation: | Tandem accelerator of the Tandetron type with a terminal voltage of 2 MV was installed in the branch office IP SAS in Piestany. It allows for the production of beams of protons, deuterons and alpha particles with precise energy between 100 keV - 4 MeV and intensity of 1 microA. In addition, to the application program of the laboratory and the program of solid state physics, that are not parts of this project we intend to use this accelerator to study the nuclear structure of neutron inelastic scattering method and the study of nuclear reactions that are important to nuclear astrophysics.Alpha process consists of nuclear reactions of (alpha, gamma) type leading in the stars to the burn of helium and production of 16O, 20NE, 24mg, 28SI, 32S, 36Ar, 40Ca, 44Ti, 48Cr, 52Fe and 56Ni isotopes. These are exothermic reactions, which energy is released via gamma radiation. Measurements of the cross section of these reactions are very important in terms of parameters of models describing the production of various isotopes and their abundance in the universe. The project will focus on investigation of the 20Ne(alpha, gamma)24Mg, 22Ne(alpha, gamma)26Mg and 24Mg(alpha, gamma)28Si for which there are no data available for the excitation function at energies of alpha particles is less than 6 MeV. This energy corresponds very well to the possibilities that are provided by the Tandetron machine in Piestany.Extremely powerful, but relatively seldom used method for the study of nuclear structure, specifically a low-spin, is the inelastic scattering of fast neutrons with the detection of gamma rays. When a tunable neutron source of mono-energetic neutrons is used, the excited states can be studied near the threshold for their production. This eliminates the common problems associated with the population from upper states. This threshold may furthermore be very accurately determined experimentally. This provides the unique location of levels from which the gamma rays originate in the level scheme. Moreover, it is possible to accurately measure the excitation function, i.e, dependence of the cross section on the neutron energy, for given gamma ray. These allow the determination of spin for level from which gamma rays originate.For neutron energies of a few MeV, inelastic scattering is the non-selective statistical process, i.e., it populates all states within the given range of energy and angular momentum. As a result, the angular distribution of the emitted radiation allows to establish spins of excited states and transition multipolarities.Measurements of lifetimes of excited levels are of extreme importance for nuclear physics, since they allow direct determination of reduced transition probabilities. They are a measure of collectivity of excited states of atomic nuclei. The most important part of information that can be obtained from inelastic scattering methodology are lifetimes within the 10 fs - 1 ps range, which can be obtained from measurements of Doppler shift of gamma lines. Gamma spectra were measured using a coaxial HPGe detector at a distance of 1 m from the sample and the lifetime is deduced from the line centroids according to the angle.Both parts of the program require to find a solution for a number of technological problems. These solutions will be an integral part of the project. |

| Annotation: | Investigation of thermophysical properties of natural materials with new sensors and methods. Thermal properties of rocks are important at solving the problems of seasonal storage of heat energy in geological formations around the houses. To optimize the process of the energy acumulation it is necessary to know the thermo-physical properties of the surrounding material in which the energy is stored. We must know the values of coefficient of thermal diffusivity, thermal conductivity and specific heat capacity for the numerical simulation of heat transport phenomena for the transfer from the heat exchanger into the bedrock materials (eg. Limestone and clay loam). In the frame of project there will be designed and manufactured single-probe thermo-physical sensors and their modifications for in-situ measurements. The new sensors will be placed in the ground in the hole bored in different geological conditions, so clay loam and rock massif. For the new single-probe sensors there will be derived the new models. |

Primary role of the proposer, CCMS, will be studies using ultra-accurate computational studies based on explicitly correlated many-body techniques, such as quantum Monte Carlo (QMC). Our preliminary results clearly indicate that use of these accurate techniques is imperative for reliable description of functionalization of these materials with d-electrons, for accurate description of electronic properties, or for description of energetics of catalytic or sensoric properties ofthese novel materials. The QMC studies will be supported by the experts at the NCSU. The results of our correlated modeling will serve as inputs into more coarse-grained spintronics modeling at the spintronics group at UREG. Our computer modeling will also serve as back-up support for the primarily SPM experiments at the OUNI and JLUG on this group of materials. As a basic research project the main outcomes are expected in the form of outstanding results publishable in highest-impact journals, numerous citations and invited talks at international conferences. These research results will be accompanied by public outreach activities in daily press and by events targeting primarily, but not exclusively, the high school students via strong presence at Tournament of young physicists, Olympiad of young scientists, Researcher’s night, etc, where top-end of the line scientific results will be highlighted. |

| Annotation: | The tasks and goals of this project are motivated by the development of effective quantum algorithms, quantum-chemistry simulations and distributed quantum information based innovations.The common denominator of all our key tasks is the concept of a network, graphically representing complex quantum-mechanical systems and the (topological) relationships among them. This network depicts interactions (in a general sense) between quantum systems, or their mutual correlations. In this project, we divided our research questions about quantum networks into three logical groups representing the above-mentioned areas. |

They are therefore referred to asbiomarkers of diseases.Sensors are based on assembled nanoparticle layers: their conductivity varies in dependence of the nature andconcentration of an adsorbed gas. Such sensor is referred to as the chemiresistor. The project deals with thedesign and fabrication of particular nanoparticles and nanoparticle layers, characterization of their transport,structural, optical, and morphological properties with the accent to sensing properties of final sensors. Theobjective of the project are functioning sensors and better understanding the response mechanism of thenanoparticle chemiresistors to specific gas and vapors.Applicable sensing layer /sensors would eventuate to simple and affordable, and thereby personal testers formonitoring of particular diseases, e.g. diabetes, in future. |

| Annotation: | Security is one of the most used words nowadays, whether in science, politics, economy or every-day life. Meaning of this word has, however, changed significantly throughout recent decades. To be secure means often to have more information than the enemy rather than to have a more powerful army than the enemy. It is of a vital importance for the whole community to achieve security of any information that is being communicated worldwide. The aim of this project is to question and re-establish security in a specific domain of protocols, namely protocols utilizing properties of Quantum physics. Many of these protocols are believed to be secure in most situations, hence we will concentrate on a very specific kind of attack, where an adversary can influence the sources of randomness used in protocols. Preliminary results show that this capability of an adversary can significantly reduce the security of existing protocols or their particular implementations and it is thus important to examine this problem in detail. |

| Annotation: | Magnesium hydride is one of the most promising materials for safe storage and transport of hydrogen. It is mostly produced by long term mechanical milling and is thus very expensive what greatly limits its practical application. This applied research project is therefore aimed to verify economically attractive method of magnesium hydride production via direct spraying of molten magnesium or its complex alloy with compressed hydrogen and produce thus proper structure for repeatable storage of hydrogen. The subject of the research is to study the effect of the composition of the melt, cooling rate, gas pressure and size of the powder particles onto the amount of hydrogen absorbed in the solid powder.In addition, the ability of such powder to absorb and desorb the hydrogen repeatedly without excessive creation of passive layer on the powder particle surfaces will be determined. The ways of further use of powder after exhausting its ability to effectively bind hydrogen will be examined as well. The successful results of the project could revolutionary help in the storage of energy from clean and renewable sources, thus contributing to the formation of sustainably clean environment. |

| Annotation: | The project consists of two separate parts, one on quantum walks (split into scatteringsand decoherence questions) and the second one on quantum incompatibility.In the first year of the project we addressed the issue of the decoherence in quantumwalks, i.e. how are the applications of quantum walks affected by decoherence on givennetwork. One partial result in this direction is that decoherence in quantum searchesrather quickly destroys its efficiency up to few extra cases. This is, however, done onlyfor a specific task related to Grover quantum search. The second result is the detectionof extraneous edges, which might be considered as a leakage in the network. Thisresult is still preliminary.Objective on quantum incompatibility aimed this year at describing a general degree ofincompatibility necessary for considering quantum incompatibility as a resource inquantum applications. This point has been addressed fully with additional results ofproviding a generalized Tsirelson bound. Further additional results, not planned withinthe project, but relating to the objective, were the expansion of the degree ofincompatibility on measurements on evolutions and the description of dynamical effectson incompatibility. |

The research programme of the laboratory is dominated with studies of reactions related to present and future nuclear energy production and to homeland security applications, especially detection of explosives and fissile material. Fundamental studies of nuclear structure, namely very short lifetime measurements, are also foreseen. |

| Annotation: | In the theory of quantum information and computation quantum walks play a role of a specificsystem that is relatively simple both from theoretical and experimental side, yet still complexenough to provide computational advantage over classical applications while being universal forcomputation in general. This can have significant implication to applications in implementation ofquantum technologies and in the near future it can serve as a good mid-size quantum simulator.A specific task relevant to advance in quantum technologies is the topic of probing quantumnetworks. In this project we plan to address this task from the specific view of scatterings ongraphs by attaching semi-infinite runways on chosen locations in graphs which serve as inputand output leads for quantum walkers. By doing so we want to first identify features of thegraphs that are recognizable by this approach, while being efficient (in the length of the wavepacket). These findings will be used for particular task such as searches for defects or their avoidance, routing of walkers, scattering simulators, programmable transports or transportsunder decoherence. For these aims we will use know-how of both groups - the Slovak partner isan expert in quantum searches and computation complexity while the Portuguese partner is anexpert in studying transport properties on graphs, spatial search by quantum walks, and howthese are affected by defects. |

The following projects are foreseen: 1) imaging and manipulation with(non-contact) atomic force microscope (NC-AFM), 2) nanotribology, (3) spintronics and magnetic nanostructureson graphene, (4) study of molecular switches. We plan predominantly use two modeling tools, namely densityfunctional theory methods (DFT) and correlated methods of quantum Monte Carlo (QMC). In particular in 1) weplan study of Al2O3 surface (alumina), for which we have high-quality NC-AFM images which will be used toelucidate the still not fully understood atomic structure. 2) In the field of nanotribology we plan to study thesuperlubric behavior of nanoparticles. In 3) we plan study of molecular magnets on graphene and in 4) chemicallyand thermally switchable molecules. |

| Annotation: | The project is focused on specific properties of new soft-magnetic nanocrystalline materials that show a high surface to volume ratio. These modern materials target high saturation induction and are developed for power electronics, which is necessary for an efficient production of electricity from renewable sources. Economic reasons dictate to use cheap and available feedstock and high induction demands to be sparing with nonmagnetic elements. Thus certain properties regarded marginal with alike older materials now become important: Macroscopic heterogeneity resulting in mutual forces between surface and interior of the magnetic component (thin ribbon, powder) can build up and significantly affect useful magnetic properties. We already study such properties on very similar ribbons in recent years. We thus believe to effectively use the knowledge and experience to achieve the project goals aimed at explaining the properties and so enabling optimal choice of composition and treatment of the modern materials. |

| Annotation: | The project deals with development of the surface processing technology based on single-point diamond turning and fly cutting and their implementation in preparation of elements for the next generation of multifunctional crystal X-ray optics, in particular those based on germanium, silicon and copper.The main parameters under study will be morphology of the processed surfaces on various length scales and degree of subsurface damage of the crystal lattice with the aim to minimize surface roughness and damaged region. This will guarantee supression of the diffuse X-ray scattering and geometrically and spectrally pure working X-ray diffraction that is particularly important for strongly asymmetric diffraction with added functionality of the beam shaping. In addition to the diamond processing the project will focus on final treatment of active surfaces of the crystal X-ray optics, namely by combination of mechanical and chemical methods as well as by utilization of ion beams and pulsed nanosecond laser source. |

| Annotation: | The aim of the research is the new knowledge on electronic transport in arrays from semiconducting iron oxidenanoparticles (NPs) combined also with graphene oxide vs. their lateral and vertical ordering. Arrays will beprepared by modified Langmuir-Schaeffer deposition and their structure will be studied mainly by GISAXS.Electronic transport in these arrays used e.g. in NP gas sensors is not understood enough. Its complexity followsfrom the combination of inter- and intraparticle components depending on the size effects. Understanding of thetransport together with surface molecular interactions is a key to advanced gas sensors for healthcare, protectionof environment and civil security. However, the research diverges and its systemization depends also on theclarification of transport. Sensors must be also thermally stable and structurally homogeneous to facilitate furtherminiaturization and integration into electronic circuits. |

| Annotation: | The project objective is to study the electromagnetic and weak structure of hadrons and light nuclei in order to test the Standard Model, through the evaluation of the quantities as running electromagnetic coupling constant alpha at the energies corresponding to the square of the mass of vector Z boson and the anomalous magnetic moment of the muon. We will deal with the analysis of the existing experimental data, using the Unitary and Analytic model and we will predict the behavior of the hadrons in conditions, which have not yet been experimentally reached up to now. Next we will re-evaluate the total light-by-light contribution and the lowest order hadronic vacuum polarization contribution to the muon magnetic anomaly, which must be evaluated with higher precision in order to determine whether the experimental value can be explained within the Standard Model. Also, we try to propose a new method of measuring the polarization of electromagnetic and weak structure of hadrons, which would allow a new perspective on the studied issue. In the framework of the covariant quark model we try to clarify the nature of heavy charm mesons, i.e., tetraquark states, and to predict their decay characteristics. |

The dominant research method will be the Scanning Charge-Transient Microscopy. Because of the mechanical properties of analysed films the interaction force between the probe tip and the imaged/analysed surface must be reduced, in order to avoid its damage, like displacement of weakly bound nanoparticles. The successful outcome of the project will extend the imaging and analytic capabilities of the instrument and its applicability for instance to imaging biological structures. |

| Annotation: | With a construction of new more efficient accelerators of charged particles, in collisions either with fixed target or colliding beams, more and more heavy strongly interacting particles have been discovered. In theoretical investigations a conception was achieved that all such particles, hadrons, are compound of quarks, existing in the framework of the Standard model in the form of six flavour. Such a conception allows us in the framework of the constituent quark (CQ) model to arrange existing hadrons into multiplets with similar properties.However, recently in electron-positron collisions on Belle and Babar new so-called X, Y and Z hadrons appeared to be experimentally confirmed also in Fermilab, which do not manifest themselves in the CQ models like conventional hadrons. The aim of this project is theoretically to investigate properties of X, Y and Z hadrons in the framework of the relativistic CQ with elaborated with experts from JINR Dubna. |

| Annotation: | The objective is to bring relevant contributions to understanding of strong interactions with emphasis on phenomena related to the vacuum structure of quantum chromodynamics and the mechanisms of confinement and spontaneous symmetry breaking. We will investigate the wave functional of the QCD vacuum, its percolation properties, and behaviour of various physical quantities in phases of strongly interacting matter. Further research topics will be the Schwinger model in covariant gauge and in finite volume, its operator solution as well as consequences of restricted gauge symmetry for axial anomaly and vacuum structure; properties of the physical vacuum state and breaking of axial-vector symmetry in the chiral Gross-Neveu model; symmetry breaking in three-dimensional light front (LF) quantum electrodynamics and SU(2) gluodynamics in Hamiltonian LF formulation and in finite volume, focusing on the zero-mode dynamics of gauge fields.Results will be published in renowned scientific journals. |

| Annotation: | The project aims at several interrelated topic related to symmetry energy and spin. Spin- and isospin- dependent version of the exciton model will be developed. Dilepton production in Au+Au collisions will be measured and contributions of possible dilepton sources to dilepton invariant mass spectrum will be analyzed.Electromagnetic calorimeter for HADES will be developed.

The influence of nuclear symmetry energy on stability and shell effects will be revealed. The excited states of neutron deficient nuclei will be studied within the framework of influence of the symmetry energy changes to the deformation of nuclei. Structure and internal composition of neutron stars will provide constraints on the density dependence of nuclear symmetry energy and state equation of nuclear matter.

| Annotation: | The proposed project responds to permanently increasing utilization of low-power microfocus sources in laboratories and brings several new solutions that substantially extend application potential of these sources and the X-ray sources generally as well. Combination of crystal optics elements and microfocus X-ray sources, that has not been studied and tested yet to our knowledge, is one of the original project outputs. The possibility of the beam compression at short distances has profound innovation potential for new construction of X-ray instrumentation working with extremely narrow beams, in particular for high-resolution GISAXS and XRR techniques. Small compressor size allows also compact solution of the primary beam optics where the Montel optics and crystal optics are encapsulated in one evacuated and from outside adjustable module. In the field of X-ray imaging we expect the main contribution in enhanced resolution of the directly converting cameras (Medipix, Pilatus). A coherence volume enhancement of the beam is an accompanying effect that allows to use not only the absorption but also the phase contrast for imaging. |

This abstract investigation is motivated by applications in quantum informationprocessing, which constitute the second objective of the present project. We will, for instance, find optimaldesigns for the so-called heralded protocols for quantum cloning and quantum learning of general quantumstructures (not only states) in the respective part of the project. We will also investigate asymptotical properties ofdiscrimination tasks, such as Chernoff bound for quantum channels. |

| Annotation: | The project aims to yield relevant contributions to theoretical understanding of strong interactions of elementary particles with focus on phenomena relevant to current and future experiments at high excitation energies and high densities of nuclear matter, and on properties of dense nuclear matter relevant for composition and internal structure of neutron stars. It groups together researchers from several centres of theoretical particle-physics research in Slovakia (Bratislava, Košice, and Banská Bystrica), with broad expertise in strong-interaction problems, ranging from “first-principle” nonperturbative studies of QCD on a lattice, through models based on QCD, phenomenological approaches to describe experimental data, to astronuclear physics. The research will concentrate on four main directions: (i) colour confinement and structure of the QCD vacuum, (ii) hard probes in processes in nuclear targets, (iii) hadron production in heavy-ion collisions, and (iv) cold and dense nuclear matter.The project is being solved in broad international collaboration. Results will be published in high-impact scientific journals and presented at international conferences. |

| Annotation: | The project is focused on the study of electrically active defects in organic semiconductors. Defects, which act as traps and recombination states of charge carriers, essentially influence the charge transport and recombination-generation mechanisms. The knowledge of the origin of defects and their control is therefore an important issue of organic electronics. The aim of the project is to obtain new knowledge on defects origin in thin films of selected organic semiconductors and its correlation with the structure and morphology of the films. This knowledge will be used in the study of the influence of intentionally introduced defects and degradation processes on the function of solar cells which will be prepared within the project. New knowledge will be obtained by the combination of standard experimental techniques suitable for electrical, optical, and structural thin film characterization with transient techniques based on the charge measurement, developed by our research group. |

| Annotation: | This project proposal reflects current technological progress and new opportunities in biomedical applications ofgraphene-based sensors. Our main goals include the design and development of a graphene oxidemultifunctional nanoplatform (GO-MFN) for the detection of tumor cells. In the first step, the development ofgraphene oxide nanoflakes of appropriate size functionalized by monoclonal antibody is planned. For sensingthe tumor cells, GO-MFN of 100 nm size able to interact with a single cell will be prepared. Magneticnanoparticles added to GO-MFN will enable the inspection of deep tissues by nuclear magnetic resonance. Thedegree of oxidation of GO, type of the functional groups, optimal functionalization with covalently boundmonoclonal antibodies and magnetic nanoparticles, are the most important technological steps. The analysis ofthe basic interactions related to tumor sensing will be conducted in vitro on 2D and 3D cell models up to theproof-of-principle stage that will be directly applicable to laboratory and preclinical testing. The GO-MFNinteraction with the cell membrane and with the cell interior will be analysed with subcellular resolution. Such anapproach will bring original knowledge and a detailed understanding of the tumor sensing process that isimportant for the optimization of the sensor sensitivity. Detection of biomolecules bound to GO-MFN will be addressed in real time by several techniques.The project is based on a complex multidisciplinary approach, ranging from physics and chemistry up tobiomedicine and combining excellent science and the most sophisticated nano and bio-engineering. Theinvolved partners possess key skills, infrastructure, antibodies and tumor models, and are highly motivated toreach the project goals. |

| Annotation: | Complex quantum systems consisting of a large number of spin one-half particles (qubits) are hard to track due to large number of parameters involved. Within this project, we aim to develop methods to conclude about properties of such systems just from properties of its subsystems of only a few qubits. Moreover, we will reverse the task and search for global states that are consistent with information obtained from local subsystems and have, in the same time, other interesting properties like symmetry, low complexity of preparation etc. This project is interdisciplinary, combining the methods of physics (quantum theory, quantum information) with informatics (graph theory). Several foreign Institutes will be incorporated into the project, mainly the Faculty of Informatics a Faculty of Natural Sciences, Masaryk University in Brno and groups from the Faculty of Physics of Vienna University. |

Two technological procedures will be developed - preparation of innovated substrates for solar cells functionalized by metallic nanoparticles and preparation of an optimized bulk heterostructure of the active layer of organic cells with incorporated metallic nanoparticles. The procedures will be tested on a complete structure of the solar cell. The project will evaluate the effect of nanoparticle parameters, self-assembling and distribution in the active layer and character of defects on the behaviour of the solar cell and will bring new physical knowledge relevant for effective utilization of plasmonic excitations in real photovoltaic structures. |

The result will be optimization of the experiment in terms of samplegeometry and in terms of measurement conditions for temperature response. Tests will be verified byexperimental measurements for the corresponding initial and boundary conditions of the heat conductionequation for the given configuration. The result depends on the impact of side effects that are included in thesemodels. In the past we have eliminated these side effects looking for the optimal geometry of the sample. Thisproject aims precisely to cases where these effects are present. Thermophysical properties of materials to someextent will be selected according to the results of the analysis of the models in order to illustrate the influence ofdisturbing effects. |

Gas sensors of trace amounts of selected pollutants and strain sensors willbe under focus. Their principle resides on electrical conductivity changes of ordered NP layer in response toambient atmosphere or strain. NPs layers will be achieved by means of Langmuir-Blodgett method modified byourselves to enable preparation of ordered NP mono and multilayers over large areas. We will usehome-developed colloidal NPs (Fe-O, Co-Fe-O, Ag-Fe-O, Sn-O, and Ag) with diameter of 5-10 nm covered byorganic surfactant. After deposition the surfactant can be removed by annealing, UV photolysis or oxygenplasma. Sensing properties of layers will be examined on micro- and nanoscale in terms of chemical compositionof NPs, their surface properties, order and morphology of NP arrays, and employed surfactant. We will proposeoptimized layer parameters in terms of sensing properties. |

Nuclear physics is one of the scientific fields, where demands for higher dimensions and better resolutions are continually increasing. In our case, we can define the basic tasks associated with the processing of multidimensional data in nuclear physics as follows: • event sorting and efficient storing of nuclear spectra, • background and noise elimination in spectra, • resolution improvement in spectra using deconvolution methods, • relevant information-carrier objects identification and analysis of multidimensional spectra, • visualization of events distribution in multidimensional spectra. The objectives of the project is to extend the research and implementation of sophisticated algorithms and methods of events acquisition, efficient storing, processing and visualization to solve the above described tasks. |

| Annotation: | Soft-magnetic ribbons prepared by rapid quenching of the melt, which are used or potentially usable in industrial production of inductive components are studied. The project aims to investigate systematically which and how the surface features affect the resulting magnetic properties. The so far modest knowledge on this matter should besignificantly complemented by the project goals. Special attention should be paid to identify the processes and/or surface-present substances, which can result in the ability of surfaces to exert force on ribbon interior. The knowledge gained can make the industrial use or new development of the materials more efficient. |

| Annotation: | The project deals with tasks of theoretical analysis of quantum and classical phase transitions in lattice models in higher dimensions which are not solvable exactly. The project is partially focused on studies of the critical properties of spin models on non-Euclidean three-dimensional spaces with a negative curvature (the hyperbolic geometry). It is thematically related to the studies of branched neural networks in organisms and it is indirectly related to spin networks in the theory of quantum gravity. The other part pf the project focuses on the analysis of a nano-particle dynamics freely moving in a liquid bound in a square geometry and affected by a various external fields. |

| Annotation: | The project responds to the necessity of multidisciplinary approach in the assessment of properties and quality of the building stone. It deals with investigation of correlations between the thermophysical properties that reflects thermodynamical state of material structure, namely thermal conductivity, thermal diffusivity and specific heat in relation to mineral composition, structure, type of structure and the number of defects in it. Influence of water content in pores of stone on heat and sound transport properties that could be influenced by cross effects caused by phase transformations of water. In this case the kinematic effect of mass transport (water, steem, air) in pores cause increased apparent values of measured thermophysical parameters. The main goal of the project is the study of relations and not well known correlations between microstructure characteristics, physical and mechanical properties and thermophysical properties aimed at the improvement of the quality and durability stones determination methodology, considering the material genesis, fabric, texture and porosity. Obtained knowledge can be applied in calculations of conventional heat losses and vapour condensation in buildings designed from natural materials as well in modelling of man`s activities influences on rock masses. Results of sensitive thermophysical measurements can help to elucidate deterioration processes in building stones influenced by temperature variations and water content. |

| Annotation: | In collisions of gold nuclei Au+Au at energy 200 GeV/n studied at Relativistic Heavy Ion Collider (RHIC) a very dense, strongly-interacting hadronic and partonic matter is created, which expands into the final state of approx. 2000 particles and anti-particles, observed in detectors. The goal of the project is to study the properties of such dense partonic matter using the correlations among momenta of produced (experimentally observed) particles in comparison with the simulations. Dependence of the correlations on the parameter of collisions such as the collision energy and centrality is studied with the aim to observe signatures of critical point and phase transition into the predicted quark-gluon-plasma (QGP) state. |

| Annotation: | The study of behaviour of molecular sytems confined within nanopores due to finite-effects, surface forces and reduced dimensionality. We might expect the large shifts in freezing and glass transition temperature in consequence of reducing of pore size to approach the range of the intermolecular forces. New surface- or confinement-induced phases can occur in some cases. The dynamical properties of confined system of molecules (polymers) are still unclear. We might understand many physical and chemical properties of molecular as well as macromolecular or biological systems using suitable subnanometric probe. The positron or positronium probe is very useful tool for the investigation of confined systems in nanometric and subnanometric scale. |

| Annotation: | Project will be devoted to establishing better experimental constraints for the Symmetry Energy at high density. The Symmetry Energy, i.e. the difference between the energy of neutron matter and of symmetric matter, is an essential ingredient in nuclear physics and astrophysics but, as of today, insufficiently constrained by experiment; in particular, its behavior at supra-saturation densities is practically unknown. New experiment will be performed at GSI Darmstadt using the CHIMERA, ALADIN and LAND detectors and analysis of the experimental data, together with re-analysis of FOPI-LAND experimental data and URQMD and IQMD calculations will provide first constrains on the symmetry energy at supra-saturation densities. |

| Annotation: | The project targets certain effects, which emerge after the post-treatment of metallic ribbons pre-pared by rapid quenching of the melt. The effects to be studied act as limiting factors – at cer-tain circumstances, their consequences could prevent reaching the soft-magnetic properties, which are desired for practical use in powerelectronics. Macroscopic forces that come from differences between the surfaces and ribbon interior as well as grain growth and appearance of a magnetically harder phase should be investi-gated as to their mutual relation. As inferred from the basic physical knowledge, there are processes, which could suppress the impact of thelimiting factors. Such processes should be inspected too |

These microscopes are designed to image specific properties of surfaces or of near-surface regions. The possibility to analyse a distinct area using different methods, without the need to exchange the probe and input module, extends the analytical capabilities of the scanning probe microscope by a sensitive method suited for analysis of defects in semiconductors and dielectrics. |

| Annotation: | By means of the elaborated by us the Unitary and Analytic model of the electromagneticstructure of hadrons and existing experimental data on the pion form factor also in the space-like region one can demonstrate a reduction of the error of e+e-annihilation into two pions contribution into muon g-2 anomaly by one order, in comparison with an error obtained by other authors integrating numerically simply throu the experimental data on the corresponding cross-section. By an extention of this method also on the other two-particle processes, as well as on the multi-particle processes, however reduced to quasi two-particle processes by measn of the suitable resonances, one can obtain a remarkable lowering of the total error of the hadronic contribution into muon g-2 anomaly andQCD Alfa(M_Z). The latter is crutial in an investigation of the revelation of the new physics beyond the standard model (SM). |

Both traditional coarse-grained materials with grain size of order of several micrometers as well as nanocrystalline and amorphous ones will be addressed. Materials will be prepared by arc melting or fast cooling of melt. Microstructure and especially behaviour of vacancies and their influence on physical and mechanical properties of Fe-Al alloys will be investigated in dependence on composition and preparation conditions. The materials will be studied in the as prepared and thermally treated states. Positron annihilation spectroscopy (PAS) and Mössbauer spectrometry (MöS) will serve as principal experimental tools. The goal is to obtain complex and original information about microstructure and the other characteristics of Fe-Al based alloys by combining PAS and MöS with a variety of additional complementary techniques available at the three institutions integrated in this common project. |

| Annotation: | There is a systematic need to develop novel organic solar cells showing distinct advantages over their inorganic counterparts due to their lighter weight, flexible shape, versatile materials synthesis, and low cost in large-scaleindustrial production. Concurrently, monitoring of environmental pollution, food-stuff quality, and drugs in a living body is of great importance. This project is directed toward the understanding of electronic, optoelectronic, and electrochemical phenomena in organic materials (e.g. pentacene, polythiophene, MEH/PPV) and nanocompositedevices with applications in both these fields. Charge injection and transport properties of these materials affected by traps will be studied by techniques based on charge transient measurements.

| Annotation: | The project aims to test physical models for the pulse transient method using the theory of sensitivity coefficients. The project includes calculations of the uncertainty for free variables in model and for constant parameters and their impact to the resulting uncertainty. The result will be optimization of the experiment in terms of sample geometry and in terms of measurement conditions for temperature response. Tests will be verified by experimental measurements for the corresponding initial and boundary conditions of the heat conduction equation for the given configuration. The result depends on the impact of side effects that are included in these models. In the past we have eliminated these side effects looking for the optimal geometry of the sample. This project aims precisely to cases where these effects are present. Thermophysical properties of materials to some extent will be selected according to the results of the analysis of the models in order to illustrate the influence of disturbing effects. |

| Annotation: | The project deals with an unresolved problem of the standard model of particle interactions: vacuum structure of nonabelian gauge theories in general, and quantum chromodynamics in particular. It is related to nonperturbative phenomena in particle physics: confinement, chiral symmetry breaking, properties of hadron spectra. Two methods are utilized: numerical simulations of lattice QCD and investigation of gauge models in light front variables. Problems include: wave functionals of ground and lowest excited states of QCD, links between confinement mechanisms and chiral symmetry breaking, relation of geometrical features of topological structures in the QCD vacuum to strong-interaction phenomena, Casimir scaling in G(2) gauge theory, and various conceptual and practical questions of quantum field theory on the light front and its relation to the usual formulation.Research topics are related to international cooperations of investigators.Results will be published in respected scientific journals. |

| Annotation: | In the project the physical properties of the amorphous hydrogenized silicon (a- Si:H)/crystalline silicon (cSi) and a-Si:H/glass heterojunction will be studied in dependence on the degree of crystallinity as well as in dependence on conditions of wet chemical passivation processes in HNO3 and HCN solutions with various degrees of activity. Afterwards the electrical, optical and structural properties of modified heterojunction as well as transformation of cluster structure in the amorphous layer and the transformation of groups of the defect states at the surface dielectric/a-Si:H interfaces inside the structure and in bulk materials will be studied. Additionally the a-Si:H/Si interface will be studied and in the final stage of the project the silicon substrate will be textured by the reciprocal pyramidal structure.Working out the project tasks can contribute to the successful forming of the heterojunction with reduced densities of the defect states at the interfaces and in bulk of the structure. |

| Annotation: | Analysis of two-level electron-phonon systems shows that they exhibit mixed phase space where regular and chaotic regions coexist. They are neither integrable (regular) nor ergodic (fully chaotic) so that they do not belong to any class of the universality of chaos found on the random matrix model basis. Complexity (chaoticity)is a consequence of the interplay of the nonlinearity (SU(2) symmetry) and phonon quantum fluctuations. We shall investigate characteristics of complexity of the nonlinear two-level electron-boson models of Jahn-Teller and exciton class. Quantum phase transitions for extended lattice Dicke and JT models (different boson frequencies and interaction parameters) and finite size effects. Interplay of selftrapping (localization) and quantum fluctuations (delocalization) and their effects on the coherence of the radiation phase. Possible applications for interpretation of optical spectra, broadening of the zero-phonon lines or the localization-delocalization transition in the sytems of ultra-cold atoms. |

Particular attention will be paid to the role of measurement and decoherence in the quantum-to-classical transition. - Analysis of the role of memory in random and quantum walks. - Investigation of joint quantum walks of many interacting walkers on the same graph. - Quantum walk in position space defined by generalized measurement associated with some POVM. Relation between discrete and continuous quantum walks. - Study of the dynamics of entanglement under bilocal quantum channels. - Robustness of multipartite entanglement with respect to local channels. - Introduction of projective ring geometrical framework for multiple-qudit system. - Role of finite geometry in quantification of entanglement. |

| Annotation: | The project is focused on enhancement of knowledge about the interactions at metal-liquid metal interfaces by simultaneous exploitations of experimental and first-principle methods. The emphasis will be on determinatin of suitable new high-temperature lead-free solder alloy compositions, which would contribute to the knowledge in the field of soldering, especially on alloys with inceased melting temperatures, e.g antimony-silver and tin-antimony, alloyed with elements influencing physical, termodynamic and technical properties (wetting, reliability, etc.) in combination with Cu and Ni substrates.The results obtained by synergic experimental research and first-principle predictions of phhase diagrams and physical properties of solder alloy systems will target, besides new knowledge, a formation of a broader set of materials with well determined properties and (technological) procedures, including a tuneable interval of soldering temperatures and enhancement of reliability of soldered joints. Progress in understanding of structures, properties and interactions in molten alloys and at their interfaces at temperatures wel below the typical „metallurgical“ temperatures (above 1000oC) is expected. The investigated systems represent ideal experimental and theoretical material basis for investigations of these phenomena with a realistic possibility of extrapolation of results also to elevated temperatures. |

| Annotation: | QMC-MACSIMA targets ultra accurate (1 kcal/mol) simulation of condensed matter systems of realistic sizes (up to 1000 electrons) using stochastic methods of quantum Monte-Carlo (QMC) for fermions. The ultra high accuracy will be achieved by treating atomic and electronic structures on the same footing, i.e. using QMC techniques. For that purpose we will use and develop nonstandard novel techniques of correlated sampling to compute ionic forces in structural optimizatioon and dynamics. Two applications are forseen. In the first we will focuss on nanotechnologies, namely on optically switchable molecules (azobenzene), with the quest to model molecular-scale optomechanical switch, in addition to the more traditional optical switch. The other proposed application will focuss on biocatalysiss in hydrogene based energy production, a technology to which the automotive industry has committed itself as an ecological substitute for gasoline. We plan to consider the enzyme of hydrogenase as an alternative to the standard Pt-based catalyst. Both applications require accuracies/system sizes precluding use of DFT/quantum chemistry methods. |

Artificial receptors - calixarenes specific for neurotransmitters such as dopamine and ephedrine will be immobilized on the surfaces of these structures and sensitivity of detection of affinity interactions will be studied by modern physical methods. The effectivity of interaction of the ligands with calixarenes will be compared with those based on antibodies. Focus will be also on preparation of nanoparticles for amplification of detection of the affinity interactions. The project outcome will be also in optimalisation of the structure of calixarenes for detection of dopamine using molecular dynamic simulations. The results of simulations will be used for synthesis of calixarenes with improved selectivity and for construction of biosensors for amplified detection of neurotransmitters using nanoparticles. |

| Annotation: | Using the combination of first-principle methods with preparation and modern high-resolution characterization of real (physical) systems, novel metallic materials will be designed, developed and investigated.Focus will be placed on the combined power of the two approaches (by ab-initio methods from the bottom and from top by controlled experimental structuring on the scales approaching nanometer scale) to determine and control properties of new alloys and to correlate/establish/explain the structure and properties of their surfaces and of the respective bulk volumes.The main interest will be placed on diverse systems based on e. g. Al and Mg and on systems based on Fe/Co/Ni with additions of transition metal elements leading to new amorphous and (nano)(quasi)crystalline alloys with properties controlled by chemical composition, structuring and newly developed physical processing methods. |

| Annotation: | Project investigates production of the very netron-rich nuclei in reactions of neutron-rich secondary beams. Measured yields of reaction products will be used for analysis of isoscaling. The slope of isoscaling plots will be used to estimate the yields of reaction products in the reactions of the unstable beams. It will be verified how is isoscaling reproduced by simulations and what physical quantities can be derived. It is specifically important to obtain information on angular distributions of neutron-rich secondary products, since experimental data available today originate mostly from the angles close to direction of initial beams and there is an assumption that the most neutron-rich secondary products are emitted at larger angles. Angular distributions of secondary products are important also for the study of production mechanisms and their knowledge will allow to estimate optimum conditions for maximum yields of desired products and determine the technical scenario for separation and eventual formation of the beam of ternary nuclei. |

| Annotation: | In the course of development new classes of thermal insulators during last years the highly porous oxides-anorganic aerogels were invented. They represent qualitatively different class of solids having high porosity and low density. Their value of thermal conductivity is similar to the one of the air itself what is challengefor the experimental techniques. They are interesting materials for investigation of physical problems. It isnecessary to build up the methodology of the measurements and introduce new physical models. It was not paidsufficient attention to the investigation of thermophysical properties of these materials in Slovakia as well as inwhole word up to now. Assumption of successful solution of the project is fact that project authors are engaged inthermophysical problems of solids for a longer time and next contributing laboratory is one of the few laboratorieswhere the synthesis of transparent SiO2 aerogels via method of high temperature supercritical drying wassuccessfully elaborated. |

| Annotation: | The attention of this project is centerd on the origin and function of macroscopic forces in soft-magnetic nanocrystalline Fe-based ribbons. Partial crystallization (separate technological step) is necessary to attain the excellent useful magnetic properties. Already during the fabrication of amorphous precursor by the rapid quenching of the melt, the so called native oxide layer is built on the ribbon surfaces. The layer transforms during the crystallization. Promoted surface crystallization appears to be linked to the layer. The chemical and structural diversity (the so called macroscopic heterogeneity) use to go together with mutual forces between the ribbon surfaces and its interior. These forces often significantly influence the resulting magnetic, as well as other resultant properties. The appearance of new materials (containing Co) with specific different properties and new general knowledge about akin materials is why this project focuses on the macroscopic forces. |

| Annotation: | The project is a contribution to the solution of the problem of magnetostatic coupling in spin valves utilizing spin-dependent electron transport. The coupling reduces the change of electrical resistance in the magnetic field.The problem is topical also for nanopillar-patterned spin valves with current-induced magnetization switching (CIMS). The project is aimed at the study of correlation between the structure of layers, interface quality, andmagnetic properties of planar spin valves with Co/Cu/Co and Co/Au/Co cores for future CIMS applications. The results will be analyzed within the Néel orange-peel coupling model with the aim to optimize the structure and to reduce the magnetostatic coupling. We will also obtain new knowledge on the effect of correlation parameters of real interfaces on the magnetostatic coupling going beyond the Néel model. New knowledge is expected further from the study of induced magnetism on specially prepared Co/Au multilayers which may be meaningful also for Néel coupling. |

The simulations will use stochatic methods of quantum Monte-Carlo (QMC) for fermions. One of the prime objectives is use and development opf techniques of correlated sampling for calculation of forces exerted on ions, to be used in sructure relaxation and molecular dynamics. We are developning these novel methods in collaboration with two top-of-the line foreign partners (North Carolina State University/Prof. Mitas and SISSA Trieste/Prof. Sorella. We forsee application of the QMC techniques to two systems of top technological importance" (1) optomechanical molecular switch based on optically switchable azobenzene molecule, (2) hydrogenaze based biocatalysis in the process of hydrogene energetics. Both applications require accuracy/system size precluding use of standard methods of DFT/quantum chemistry. In addition to development of techniques of QMC calculation of ionic forces, the postdoc will work in close collaboration with two PhD students on the two applications. The expertise in QMC techniques combined with the work on projects representing top-of-the-league knowledge-based economy will create excellent starting conditions for future reserach work of the postdoc fellow. |

Application of stress allows to shift and control population of reactant electronic levels in a catalytic reaction and thereby to control their reactivity. Using mechanical stress makes it possible to control electronic population of reactant\'s electronic levels and hence to control their reactivity. Mechanical stress at the nanoscale can be applied in devices such as static atomic force microscope. The study will use methods of supercomputer simulation with density functional methods. The project will target two applications with key industrial importance: CO2 catalysis catalyzed by gold nanoparticles under stress and water dissociation. |

| Annotation: | In the following paragraph, the project of bilateral cooperation is presented where the central objective is a common development of the cutting-edge X-ray GISAXS instrumentation addressing the vital needs of new nanotechnology branches of research and industry.Primary contacts between the Institute of Physics, Slovak Academy of Science (SAS) in Bratislava and Department of Material Physics, University of Leoben in Leoben were established in early 2008. The central cooperation point is the development and application of a table-top GISAXS system for requirements of applied surface science and industry. Up to now the GISAXS schemes were confined to large-scale synchrotron facilities with severe limitations on the1Project descriptionbeamtime. An adaptation of the existing table-top SAXS system such as Nanostar manufactured by a German company Bruker AXS seems to be a way how to introduce and widespread the GISAXS measurement technique directly to research and development laboratories. Our pilot laboratory experiment shows that the results from the modified Nanostar system compare excellently with those from the SAXS beamline BW4 at Hamburger Synchrotronstrahlungslabor. Some particular details of the pilot experiment are presented in next paragraph. Based on these findings, we are deeply confident about the merits of a continuing cooperation between the SAS in Bratislava and University of Leoben. In this project, we ask for promotion and support of the cooperation via “Aktion Österreich-Slowakei”. |

| Annotation: | The project deals with aspects of elementary particle interactions that cannot be addressed (reliably) using perturbative methods of quantum field theory. In particular, the investigated problems will include the physical mechanism of confinement in quantum chromodynamics on the lattice, where the emphasis will be put on common features of various models and approaches; the analysis of symmetry breaking and vacuum structure in light-front field theory models (self-interacting scalar theory in the broken-symmetry phase, two-dimensional SU(2) gauge theory with massive adjoint fermions); formulation of higher-order renormalization group equations and investigation of their applications within the Standard Model; and the determination of the pion-nucleon sigma-term, related to the strangeness content of nucleons and playing an important role in the understanding of strong-interaction phenomena.Project topics are closely related to international cooperations of the investigators.Results will be published in respected scientific journals. |

| Annotation: | The aim of the project ist the investigation of new possibilities of microscopic analysis of semiconductor and dielectric materials and structures, by local capacitance- and charge-transient spectroscopy om sub-micrometre level. The analysis will utilise the isothermal relaxation of charge carriers from deep energy levels characteristic of the material itself, created by intenrional doping or by impurities and other defects. Within the project, the scanning capacitance microscope will be converted, by additional components and necessary software, into a capacitance- and charge-transient spectrometer/microscope. The instrument will be utilised in investigation of defects and physical processes in silicon films, and functionalised Langmuir-Blodget films. The successful outcome of the project will open new possibilities of local analysis and two-dimensional imaging of nanostructures and defects in them. It will deepen our understanding of physical and chemical processes in materials. |
| Scanning Capacitance Microscope with High Sensitivity and resolution, and Lateral Force Probe Control | |

| Evidence number: | 2/5097/25 |
| Program: | VEGA |
| Project leader: | Ing. Lányi Štefan, DrSc. |
| Annotation: | The goal of the project is the research, development and realisation of a novel Scanning Capacitance Microscope. It will be achieved by application of a new method of probe to imaged and analysed surface position control, and new solution of transducer electronics, offering optimal signal-to-noise ratio and reduction of heat dissipation.The successful outcome of the project will increase the sensitivity of the capacitance microscope by nearly two orders of magnitude compared to that achieved in practice by microscopes representing the present industrial state of the art, and it will surpass by nearly one order of magnitude the sensitivity of the best known solutions. This will make the application of capacitance microscopes to more sofisticated analytical methods possible than it was possible hitherto. |

| Annotation: | The project is based on a strong collaboration with foreign experimental groups (Osaka University, GiessenUniversity, North Carolina State University, University, Regensburg) with the objective to provide theoreticalmodeling to those experiments. The following projects are foreseen: 1) imaging and manipulation with(non-contact) atomic force microscope (NC-AFM), 2) nanotribology, (3) spintronics and magnetic nanostructureson graphene, (4) study of molecular switches. We plan predominantly use two modeling tools, namely densityfunctional theory methods (DFT) and correlated methods of quantum Monte Carlo (QMC). In particular in 1) weplan study of Al2O3 surface (alumina), for which we have high-quality NC-AFM images which will be used toelucidate the still not fully understood atomic structure. 2) In the field of nanotribology we plan to study thesuperlubric behavior of nanoparticles. In 3) we plan study of molecular magnets on graphene and in 4) chemicallyand thermally switchable molecules. |
