SolidTrack - Operando Tracking of Solid-State Batteries for Enhanced Performance

Other cosolvers:	Slovenská technická univerzita v Bratislave
Annotation:	Solid-state batteries hold immense potential to revolutionize energy storage due to their high energy density and enhanced safety. However, realizing their full potential necessitates deeply understanding their dynamic behavior during operation. To this end, this project aims to develop and refine operando techniques to track critical parameters, such as phase changes, chemo-mechanical stresses, and interfacial resistances, in real time. Specifically, we will focus on two key techniques: operando X-ray Diffraction (XRD) and operando Galvanostatic Electrochemical Impedance Spectroscopy (GEIS). We will develop a scanning laboratory XRD technique utilizing a microfocus X-ray source (Ag Kα). This approach will allow us to monitor phase changes and chemo-mechanical stresses with a spatial resolution of 0.1 mm and temporal resolution in minutes. Furthermore, by superimposing GEIS on charging/discharging currents, we will enable real-time monitoring of impedance changes at a wide range of time scales, from nanoseconds to seconds. This methodology will provide an efficient testbed for advanced operando battery characterization at synchrotron facilities, supported by the ongoing EU Horizon projects OPERA and SEATBELT. It will also facilitate collaborations at the European free-electron X-ray laser through the EU Horizon project UltraBat, ensuring high scientific excellence and innovation.

SAS cosolvers:	RNDr. Dubnička Stanislav, DrSc., Mgr. Holka Lukáš, Dr. rer. nat. Ing. Liptaj Andrej, PhD., RNDr. Martinovič Lubomir, CSc.
Annotation:	Recent measurements at accelerators with high intense colliding beams place great emphasis on the accurate evaluation of observables. In order to describe the particle structure eruditely, it is necessary to have a suitable model that is consistent with the measured data. Not all theoretical models dealing with electromagnetic structure give a plausible description. It turns out that models based on various analytical properties of the S-matrix, unitarity, causality, locality of interactions, and other assumptions posses such capabilities. The project goal is to investigate the electromagnetic structure of selected particles from the perspective of a model that has these properties builtin. The second project goal will be evaluation of observables in terms of the covariant quark modelfor heavy meson decays, focusing specifically on those decays that have the potential to contribute to explain the physics behind the Standard Model and are also will be the subject of research at current accelerators.

Annotation:	The project focus is preparation and implementation of the concept of substitution of existing equilibrium Wyckoffcrystallographic positions in known equilibrium crystalline lattice by different types of majority metal atoms consisting of a set of 3-5 additional/other suitable atoms. These atoms, so-called HEA atoms, will be selected in accordance with the principle of High Entropy Alloys (HEA) or compounds e.g. ceramics, dielectrics or oxides, to form a similar, mutually shared crystallographic structure with lattice parameters comparable to those of the original equilibrium unit cell and are inserted for the purpose of controlled optimization of physical properties of the system. Objects of application of such concept will be alloys derived from classical known HEA but alsosystems forming metallic glasses of metal-metalloid type, porous catalytic materials, selected ceramics based on carbides and borides or oxides, using possibility to prepare systems in non-equilibrium state via different cooling rates.

Annotation:	Glioblastoma is one of the most aggressive types of cancer and is generally always fatal. Recurrence after initial eradication is extremely high and tumors appear locally with increased resistance to therapy. Locally mediated photothermal therapy is a highly promising treatment option for glioblastoma. It allows the destruction of the tumor using heat as a drug-free tumor treatment, thus bypassing glioblastoma heterogeneity, blood-brain barrier limitations, and conventional drug resistance mechanisms, without affecting the surrounding healthy tissues. Implantable or injectable hydrogel matrices are able to transport therapy agents to the tumor site and unload upon stimuli. Although there are numerous studies describing such structures for glioblastoma treatment, they mainly focus on more efficient local drug or immunotherapy mediator’s delivery. Moreover, up until now, these studies lacked detailed nanoscale investigation of nano-bio conjugates’ properties and activity on a fundamental nano-level. The NanoGlow project aims to develop i) functional “Trojan horse” hydrogels with embedded photothermal nanoparticle conjugates, ii) validated in vitro and iii) complemented with state-of-the-art structural and chemical mapping at the nanoscale. Photothermal, pH-responsive MoOx nanoparticles will be conjugated with tumor-homing RGD peptides and embedded in nontoxic, biodegradable poly-(2-oxazoline)- and bio-sourced Tulipalin A-based matrices. Near-field nanoscopy, Atomic Force Microscopy Force Spectroscopy, and Confocal Raman Microscopy of nanoconjugate-hydrogel superstructures and in vitro samples will characterize nanoscale related phenomena observable at the macroscale. NanoGlow’s unique nano-to-macro approach will provide a basis for the application of the proposed hybrid structures in the fight against complex and hard-to-treat glioblastomas.

Annotation:	The goal of the proposed project is the synthesis of ternary chalcogenides with perovskite structure and systematic characterization of the relationship between the composition, structure, optical properties, thermal and chemical stability with the potential in the application in photovoltaics, or other optoelectronics. The result will be a set of prepared pure ternary chalcogenides in the form of crystalline powders and thin films with known, as well as newly prepared compositions and a comprehensive characterization of their optical and electronic properties, as well as thermal and chemical stability. Ternary chalcogenides will be prepared also by wet approach at lower temperature up to 350 °C in the form of nanocrystals which will be characterized in terms of their structure and morphology. Proof-of-concept solar cell will be prepared, which has not yet been reported in the literature. The optimization will be done based on performance measurements.

3D printing of filaments with "non-conventional" fillers for special applications

Project leader:	Mgr. Hvizdošová Annušová Adriana, PhD.
Annotation:	The project is focused on R&D of new unusual and progressive polymer composites usable in 3D printing.The main goal of the project is to study and improve the compatibility of fillers (waste materials/hemp fibers,volcanic dust, etc., MoOx nanoparticles, metallurgical silicon) with polymer matrices, either biodegradable(polylactic acid, polycaprolactone) or synthetic (polyethylene terephthalate glycol). The material will be preparedin the form of filaments for 3D printing, characterized by many physicochemical methods, and also directly oncommercial 3D printers. Given that half of the monitored fillers are unwanted waste accumulating in theenvironment, the project will also help to process such material and its economic use. These fillers will enablemuch cheaper production of the final product, reduction of consumption of materials, energy, recycling, etc. Theproduction of such composites is a response to the demand of the european industry, the protection of theenvironment, and natural resources.

Annotation:	The project POMBIO aims to synthetize and characterize pH-active polyoxometalate (POM) -based nanostructures, specifically Fe-Mo based polyoxomolybdates (POMos), and explore their potential as new generation photothermal cancer therapy agents. It specifically aims to study in depth the pH-dependent photothermal properties of the nanostructures in model environments and in vitro, which until now remained largely unexplored in the literature. The project involves nontraditional analytical and imaging techniques, which is an original approach to complement the well-established biochemical methods, providing a unique perspective on the cellular fate of these nanomaterials and offering new insights into their interactions within the biological environment. This interdisciplinary research leverages the combined expertise of a distinguished French, Austrian and Slovak teams.

SUPERSPIN - Superconducting spintronics and emergent phenomena in low/dimensional superconductors
Duration:	1. 5. 2022 - 30. 4. 2027
Evidence number:	IM-2021-26
Program:	IMPULZ
Project leader:	doc. Mgr. Kochan Denis, PhD.
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.

ZERO - Zero-excess solid-state lithium batteries
Duration:	1. 7. 2023 - 31. 12. 2026

Precnerová Magdaléna, PhD., MSc. Raza Muhammad Arslan, M.Sc. Sahoo Prangya Parimita, Ph.D., Dr. rer. nat. Šiffalovič Peter, DrSc., Mgr. Šimon Erik, PhD.
Annotation:	The zero-excess solid-state battery (SSB) concept, also known as an anode-free battery, where the anode is formed in-situ at the interface between solid-state electrolyte (SSE) and current collector (CC), is preferred due to additional energy density gain, reduction in material and cell production costs, and simplification of recycling. In addition, the lower amount of Li required reduces Li supply problems and the likelihood of undesirable reactions. This concept has already been demonstrated for liquid cells, and recently the first zero-excess SSBs (ZESSBs) have been demonstrated. Nevertheless, ZESSB technology is still in its infancy due to the inherent challenges related to the in-situ formation of Li anode, which limits battery performance. To infer knowledge-based optimization strategies, a deeper understanding of the fundamental processes involved during anode formation at the interface between SSE and CC is required. The central hypothesis of ZERO project is that by real-time monitoring of Li deposition rate, wetting and/or alloying, and mechanical stress at the SSE/CC interface, we can optimize and tailor SSBs providing higher capacity and cycling lifetime. This can be achieved by controlling charge/discharge currents, appropriate alloy-forming interlayers, and managing internal stresses by external loads. The main aim of ZERO project is to develop optimal alloy-forming interlayers and charging strategies to achieve the high capacity and cycling lifetime of ZESSBs. This will be enabled and connected with the developing and/or updating methodologies that will facilitate experimental monitoring and a better conceptual understanding of the growth phenomena involved in the formation of the Li anode in ZESSBs. To this end, we will develop novel laboratory and synchrotron techniques to explore ZESSB-related phenomena under in operando conditions.

SAS cosolvers:	Mgr. Chernyak Yuri, Mgr. Masničák Nikolas, Mgr. Mohammad Ijaz Ahamed, RNDr. Pivoluska Matej, PhD.
Annotation:	Conventional supercomputers seem to be outpaced by increasing demand for computational power when developing new drugs, modeling nanoparticles or assessing problems in materials science and nuclear physics. Quantum computers are expected to provide exponentially growing power thanks to their use of quantum effects and indications of so-called quantum advantage have been demonstrated. Unfortunately, the current capabilities of quantum computers are rather limited by numerous issues. Because of them, the quantum computing performed nowadays is described as the Noisy Intermediate-Scale Quantum (NISQ) era.Currently the most promising algorithms for practical purposes are hybrid algorithms, where only part of calculation is performed by a quantum computer. An example of such an algorithm, is the variational quantum eigensolver (VQE), which calculates the smallest eigen-value of an input matrix. Within this project we aim to develop resource efficient methods of VQE that would work on existing quantum computers.

Shape coexistence in atomic nuclei
Duration:	1. 1. 2024 - 31. 12. 2026
Evidence number:	2/0175/24
Program:	VEGA
Project leader:	Mgr. Herzáň Andrej, PhD.
Annotation:	The manifestation of shape coexistence in nuclei with one closed shell was recognized already forty years ago. It is likely to occur in all nuclei. If it was possible to perform shell-model calculations in a sufficiently large space, intruder states and their deformations should appear. Currently, such calculations are not generally possible. Experimentally, we observe real structures characterized by E2 transitions, with different quadrupole moments and reduced transition strengths, i.e., B(E2) values. To determine the B(E2) values from the measured data, it is necessary to know the lifetimes of the respective excited states and the branching ratios of the corresponding electromagnetic transitions. In the project, we will focus on the experimental determination of these quantities in stable nuclei near Z = 20, 50, for which it is possible to perform measurements with ultrahigh statistics. At the same time, we will continue the research program focused on the systematic study of neutron-deficient odd-mass Au.

Ziman Mário, PhD.
Annotation:	The basis of today’s quantum technologies originates in quantum foundations research performed in the last century, which redefined the concept of information and set new theoretical limitations on information processing. This new information-theoretic perspective resulted in development of resource theories, general probabilistic theories and higher order quantum structures - the frameworks not only extending the quantum theory, but also enabling technologies beyond the quantum ones. DeQHOST will contribute to development of higher order concepts and methods, investigation of their mathematical frameworks, and optimizat ion of newly designed information processing protocols. The activities of the project are organized in three workpackages focused on higher order structures, resources and tasks, respectively. In particular, we plan to explore extensions and modification of the existing frameworks of higher order maps, in quantum theory and in the more general setting of operational theories, with the aim to unite their desirable features and maximize the scope of describable types of phenomena such as causal non-separability. Our goal is to understand how these frameworks can be utilized for optimization of tasks in future networks of quantum devices. One of the objectives will be the development of a higher order calculus for unitary channels. In our study of resources, we will concentrate on incompatibility of quantum instruments, channels and possible extensions to higher order maps. We will study memory effects as a resource for information processing and generalize a resource theoretic approach to quantum thermodynamics. Our findings will be applied to specific tasks as designing programmable quantum processors, discrimination of memory channels, comparison and convertibility of higher order maps and a study of complexity questions in the higher order setting.

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.

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.
