| Annotation: | Alzheimer’s disease (AD) is the most common neurodegenerative disorder, sharing unclear pathophysiology and massive social costs. Today, more than 55 million people have been diagnosed with AD, which is forecast to increase more than twice by 2050. AD is tightly associated with the formation of deposits containing amyloid β (Aβ) peptide organized into insoluble amyloid fibrils. Despite numerous contemporary studies focused on reducing Aβ aggregation, a cure for AD has not yet been found. Our project intends to implement the elements of molecular mechanisms underlying the remarkable phenomenon of plant desiccation tolerance and develop a new Aβ anti-aggregation strategy. Late Embryogenesis Abundant proteins (LEAPs) are markedly induced upon desiccation and can stabilize the native structure of proteins and membranes by a mechanism that is not fully understood. The primary project aim is to investigate the structural properties of Ramonda serbica LEAPs and their interactions with Aβ peptides and aggregation. Firstly, we will recombinantly produce LEAPs with the highest potential to inhibit Aβ aggregation. Further, we will analyze LEAPs’ secondary structure under different conditions, focusing on their order-to-disorder transitions. The final aim is to identify Aβ/LEAPs interactions and assess the Aβ anti-aggregation potential of LEAPs in vitro, which will impact the development of new strategies for AD treatment. The collaborating teams involved in this project (Slovak - IEP SAS and Serbian - IMGGE) were selected based on their expertise in protein production, protein structure analysis and amyloid aggregation. The expertise transfer between partner laboratories will be ensured by mutual training of PhD and postdoc researchers involved in the project. |

| Annotation: | Protein misfolding neurodegenerative diseases (NDDs), such as Alzheimer's and Parkinson's diseases, result in extensive cellular and neuronal loss within the central nervous system. Despite the distinct manifestations of these disorders, they share several common pathogenic mechanisms. Current pharmacological interventions are ineffective. Moreover, the complexity of NDDs necessitates innovative therapeutic approaches. In this project, the novel "multi-target-directed ligands" (MTDLs) strategy will be employed as it focuses on development of novel compounds modulating multiple factors simultaneously. We will focus on Chinese herbs - Angelica sinensis, Ligusticum chuanxiong, and Cinnamomum cassia. The project aims to explore the anti-aggregation potential of these herbal extracts and their derivatives targeting both Aβ peptide and α -synuclein, showcasing neuroprotective and anti-inflammatory properties to pave the way for the development of novel t herapeutic strategies for NDDs. The project combines the expertise and experience of both research teams in the field of protein misfolding and NDDs pathology, allowing us to acquire complex data with the aid of complementary approaches, leading to the suggestion of possible alternatives of therapy against these devastating diseases. Moreover, this collaborative research partnership will present an excellent opportunity for both teams' young members to learn new techniques in the well-equipped laboratories at East China University and IEP SAS and gain new experience by working in an international scientific environment. |

| Annotation: | Proteins displaying remarkable structural and functional characteristics such as biocompatibility, biodegradability, abundance, and reduced ability to induce immune and tissue inflammatory responses possess great potential for the manufacture of hydrogels. In addition, all proteins have the potential to be cross-linked, therefore by employing physical, chemical, and enzymatic treatments, proteins have innate benefits for hydrogel-forming. Amyloidal proteins are a category of programmable self-assembled macromolecules, and their assembly and owing to the programmability of the self-assembly of amyloidal structures, the consequent nanostructure can be manipulated rationally. Moreover, self-assembly allows the co-assembly of two or more types of building blocks, resulting in increasingly structurally complex nano-assemblies that may have physical and chemical properties distinct from those of the original mono-structures. Therefore, in the crosslinking-controlled strategy, by changing the nature and concentration of proteins, the resulting physical-chemical properties of amyloid-inspired hydrogel can be rationally tuned. Motivated by this, the proposal is aimed at basic as well as applied research and is represented by two major goals: a) preparation of single (one)-type amyloid-based hydrogels; b) fabrication of mixed protein-hydrogels by entrapping DNA-protein hybrids that could lead to the developing new materials with unprecedented structural and functional features; (c) the application of advanced nonlinear optical microscopy for rapid 3D multiphoton fluorescence imaging and second harmonic generation imaging to investigate hydrogel structures; and (d) the integration of deep learning-based image enhancement techniques to improve 3D image quality and capture detailed structural information. |

| Annotation: | The ESA’s JUICE (JUpiter ICy moons Explorer) mission (http://sci.esa.int/juice) have to face to very hostile environment of Jovian radiation belts where the penetrating energetic electrons dominate. The Particle Environment Package (PEP) payload of this mission (http://sci.esa.int/juice/50073-science-payload ) was developed within a wide international collaboration led by Swedish Institute for Space Physics IRF in Kiruna. Due to limited available mass for efficient radiation shielding, the PEP payload will operate in rather unfavourable environment of penetrating energetic electrons that will affect the detection process inside the PEP/JDC (Jovian plasma Dynamics and Composition) sensor. To mitigate the unfavourable influence of the penetrating electron radiation to the plasma ions detection process, a concept of anti-coincidence module (ACM) has been identified within the PEP consortium. The project involves development of space-flight grade semiconductor solid state detector, the processing electronic board and a laboratory testing and calibration system RATEX-J (RAdiation Test EXperiment for JUICE). The JUICE probe has been successfully launched 14.4.2023 from space port Kourou. The PEP science suite has been successfuly commissioned in June 2023. The JUICE probe will be inserted into the orbit around Jupiter on 18. July 2031. |

| Annotation: | Protein self-assembly processes independent of external energy sources and unlimited in-dimensional scaling have become a very promising approach for developing new materials with unprecedented structural and functional features. The best examples of self-assembled materials can be found in nature, including functional and pathological amyloid fibrils. Motivated by this, the proposal is aimed at basic as well as applied research and is represented by two major goals: a) anti-amyloid study - focusing on pathological amyloid aggregation connected with neurodegenerative diseases that will optimize the application of newly prepared compounds/particles in the treatment of amyloid-related diseases and enable imaging of amyloid formation/decomposition; b) fabrication of protein superstructures by chemical appending of functional ligands onto self-assembling peptides or proteins lays the foundation for developing new materials with unprecedented structural and functional features. Therefore, the development of the single-molecule orientation and localization microscopy (SMOLM), together with the deep-learning modeling for the localization and reconstruction of SMOLM images will help rapidly perfect the high-content analysis of the structural-morphological features not only the pathological amyloid aggregates but also superstructures consisting of amyloid scaffolds and connected bio-structures (DNA) and ligands. Moreover, the single-molecule orientation and localization microscopy could significantly contribute to understanding not only the process of protein self-assembly but also the mechanism of the binding and release of biologically active agents, formation and reorganization of multiple protein arrangements upon interaction with biologically relevant ligands/molecules. |

| Annotation: | Nanoparticles (NPs), including those with magnetic properties, have attracted significant scientific interest due to their applications in various fields of science and medicine. As a consequence, several promising treatment procedures have been developed, such as controlled and local drug delivery and release, photo- and sonodynamic therapy, and thermal therapy. NPs can also be used as biosensors or imaging contrast agents. Additionally, they are being studied for their potential role in amyloidogenic diseases. Although great efforts have been made to understand the pathogenesis of these diseases and design effective therapy, there is still no treatment for amyloid - related diseases. A possible alternative non-pharmacological option for targeting cross - using energy generated by magnetic NPs as a result of applied magnetic field and/or ultrasound to disrupt large amyloid structures (plaques) into smaller fragments. This proposal is aimed at basic as well as applied research that will help perfect the application of magnetic NPs in the treatment of amyloid-related diseases via thermal and ultrasound-induced processes and enable tomography imaging of amyloid formation/decomposition. Efficacious drug/NPs deposition in the target site and operated activation of therapeutic and imaging agents reduce treatment time, while avoiding adverse damage and side effects resulting from systemic administration. The collaboration will not only promote the bilateral exchange of knowledge, technology and experience, but also may accelerate the translation between biophysical/biochemical science and clinical study. |

| Annotation: | Borides form a broad class of materials with diverse physical properties. Metallic geometrically frustrated magnetic tetraborides (REB4), where RE represents an element from the rare earth group, are quasi-2D frustrated systems with different anisotropy strength and the same crystal lattice. These systems form an ideal environment for studying the connections between anisotropy and magnetization processes. With the help of the deviation of the magnetic field from the easy axis of magnetization, it will be possible to observe those components of inter-spin interactions that do not appear when the field is oriented in the direction of the easy axis, which will contribute to the development of more accurate theoretical models. By studying quantum oscillations in SmB6, which is considered to be a representative of strongly correlated topological systems, and in other selected hexaborides, it will be possible to contribute original results to the long-standing debate whether SmB6 is a topological insulator or not. |

| Annotation: | The current increase in electricity consumption and the greening of its distribution, together with the increase in the price of materials for the production of distribution transformers, represent a challenge for applied research in electric power engineering. The intention of the presented project is to respond to this challenge by functionalizing the current liquids used in electrical transformers in order to increase their cooling efficiency while maintaining or improving their dielectric and insulating properties. For this project, the liquids used in the distribution transformers of the manufacturer interested in this research will be selected. These are commercial liquids primarily based on liquefied natural gas, synthetic and natural esters. Based on current state of the art, the liquids will be functionalized by means of nanotechnologies and nanomaterials, which can significantly improve thermal conductivity, natural and thermomagnetic convection, and thus make the overall heat transport in the liquids more efficient. The functionalizing nanoadditives will be mainly made from carbon (fullerene, nanodiamond) and iron oxides or other ferromagnetic elements. The functionalized liquids will undergo laboratory measurements of physico-chemical, electrical, magnetic and thermal properties. Based on the analyzes of laboratory experiments and numerical simulations, nanofluids with the greatest potential for improving the thermal and insulating properties of the transformer will be selected. The selected nanofluids will be tested by the industrial partner (the customer of the research results) and applied in the selected distribution transformer. The transformer will be subjected to electrical and temperature rise tests. One can expect that the nanofunctionalization of the liquids will result in a lower operating temperature of the transformer, which can lead to an extension of the transformer service life and to the production of smaller transformers. |

| Annotation: | Ultralow temperatures have become an important tool for new research avenues in nanoscience, materials research and particularly in quantum nanotechnologies. Scaling down a physical system towards the sizes when the quantum properties surpass classical physics opens a plethora of new quantum-driven effects, thus giving rise to new classes of quantum materials. Within the proposed project we will focus our study on low-dimensional quantum devices, heterostrucures consisting of atomically thin superconducting slabs and aditional layers with different order (inslulator, metal, ferromagnet). In such systems symmetries can be broken possibly allowing for non trivial topological quantum states relevant for future technologies. Atomically thin layered materials are systems with zero limit bulk-to-surface ratio. Their physical properties are strongly affected by interfacing with other systems. Therefore, they represent an accessible platform for the abundance of quantum effects that can be engineered by combining them into vertical stacks using exfoliation techniques. One identifies two types of layered systems – atomically thin artificially prepared van der Waals heterostructures [Science 353, aac9439 (2016)], and naturally layered three-dimensional crystal systems. A special class of naturally layered materials is misfit structures combining alternating atomic layers of hexagonal transition metal dichalcogenides and slabs of ionic rare-earth monochalcogenides in the same superlattice [APL Mater 10, 100901 (2022)]. They feature new state of quantum matter, the Ising superconductivity resulting from broken inversion symmetry and strong spin-orbit coupling as has been recently shown by us. The misfits are also exfoliative and thus incorporable as units in vertical stacks. |

| Annotation: | One of the fundamental results of quantum mechanics in the 1920s was the derivation of relativistic equations for massive fermions (Dirac), massless fermions (Weyl) and fermions that are themselves antiparticles (Majorana). Since those times, particle physics has been searching for particles representing Weyl and Majorana's fermions. However, their search has not yet been successful. In the last twenty years, it has been shown that the band structure of some materials has such unique characteristics that the charge carriers in them can behave according to the dynamics satisfying the Dirac or Weyl relativistic equations. Such materials include compounds from the group of transition metals dichalcogenides, which we will focus on in our project. We will work with very thin layers of selected materials from this group, such as PtSe2, MoTe2 and WTe2. The first step in the implementation of the project will be the preparation of such layers by chalcogenisation of thin films of transition metals. Their transport and optical properties will then be thoroughly investigated. Temperature-dependent transport measurements can show us transitions between different structures of the same material. We expect that a metal-insulator transition can be observed when the thickness of such thin films is varied. Some of these materials can go into a superconducting state at very low temperatures. We will also try to induce this state in close proximity, i.e. when the thin layer is in contact with another superconductor. Optical measurements will be correlated with transport measurements. We derive essential frequency-dependent characteristics, such as optical conductivity, from the latter. We will look for characteristics theoretically predicted for Dirac and Weyl fermions in the optical conductivity. |

| Annotation: | This project aims to explore the fundamental properties and technological potential of thermal and quantum phase transitions in low-dimensional quantum magnetic systems. To address these highly topical challenges emerging at the intersection of quantum magnetism and quantum information science, we will employ state-of-the-art analytical and numerical computational methods including exact mapping transformations, localized-magnon theory, exact diagonalization, classical and quantum Monte Carlo simulations, density-matrix renormalization group method, tensor-network techniques, etc. A primary focus will be on optimizing the cooling efficiency of magnetocaloric cycles near phase transitions of 2D quantum magnets, which could contribute to the development of energy-saving cooling technologies crucial for quantum computers based on superconducting qubits. Additionally, we will investigate the stability and phase transitions of skyrmion phases in frustrated triangular antiferromagnets with possible implications for spintronic applications. Another key objective is to study topologically nontrivial quantum states, particularly cluster-based Haldane states and bound magnons in frustrated quantum spin systems, which may provide promising platforms for quantum computing, quantum information storage and processing. Furthermore, we will also explore the optimization of quantum heat engines based on magnetic spin systems assessing their efficiency for energy conversion and quantum batteries. Another specific task of the project is the study of quantum entanglement and quantum phase transitions in fractal lattices with the aim to uncover the impact of complex lattice geometries on quantum correlations and critical phenomena. |

| Annotation: | Protein self-assembly is a process based on autonomous, non-covalent interactions between distinct building blocks without requirement of external energy sources. The possibility of chemical appending of functional ligands onto self-assembling peptides or proteins lays the foundation for developing new materials with unprecedented structural and functional features. Especially using sequence addressable DNAs, the synergistic combination into DNA-protein self-assembling systems, may lead to unique and sophisticated functional hybrid nanostructures, which are highly programmable and display remarkable features that create new opportunities to build materials on the nanoscale. Inspired by the unique ability of proteins to self-assemble into amyloid fibrils, we plan to use recombinant spider silk eADF4(C16) protein, insulin, Aβ peptide and lysozyme in order to demonstrate the versatility of the concept of DNA-assisted self-organization of higher-order fibrillar structures. We will explore two dynamic association modes, the temperature-controlled hybridization event of short overlapping DNA sequences and the highly specific DNA-aptamer-to-ligand binding controlled by the ligand affinity. Generally, we foresee the feasibility of the proposed nanofibrillar systems mate of DNA-protein hybrids for the construction of nanostructured materials in biomedical research for binding and release of biologically active agents, formation of multiple protein arrangements for efficient enzymatic cascades or even dyes positioning for efficient light harvesting systems. |

| Annotation: | The development boom of biomedical lab-on-chip (LOC) applications during the last two decades brought the need for the miniaturization of conventional mechanical actuators, sensors, and manipulators. Light-driven mechanical microstructures, trapped and moved by optical tweezers, can be easily integrated into the microfluidic LOC environment. The vast majority of light-driven microstructures is prepared by two-photon polymerization. It is the main objective of the present project to exploit the possibilities of working with flexible (deformable) microstructures, which were not used in biomedical applications, yet. Two well-defined LOC application areas are targeted: micro-rheology and single-cell manipulation. Micro-viscometers utilizing the effect of the surrounding fluid medium on the deformation (deflection) of flexible micro-cantilevers will be developed. The novel viscometer devices will be either anchored to the bottom glass surface or kept mobile and optically transportable inside the micro-fluidic system. Light-driven elastic micro-robots will be designed and tested for capture, transport, and release of single live cells. The operation of the developed micro-manipulators will be automated to build multicellular systems, mimicking the tissue conditions, in an autonomous way. To facilitate the flexible microstructure development and optimization, the material properties of the photo-polymers will be determined by comparing experimental deformation data with the results of numerical simulations. |

| Annotation: | Today, nanoscale materials are of great interest for their potential to be used in a wide range of areas, especially in biomedical applications such as detection, early diagnosis and effective treatment of oncological disease. One of the therapies that are actively being developed is magnetic hyperthermia (MH) as an alternative approach for the local treatment of tumours. MH utilizes the heat generated by the magnetic nanoparticles (MNPs) when are subjected to an alternating magnetic field. Thus, the better MNPs are heated, the lower concentration of MNPs in the cancer tissue is required resulting in reducing the risk of side effects. Therefore, the heating ability and heating rate of these MNPs is extremely important. In this regard, the clustering of MNPs into nanoflowers, novel systems in terms of morphology showing a structure similar to a flower, can improve their heating rate of these MNPs is extremely important. In this regard, the clustering of MNPs into nanoflowers, novel systems in terms of morphology showing a structure similar to a flower, can improve their heating characteristics compared to their building blocks, i.e. monocrystals of MNPs and thus increase the heating efficiency of MH. |

| Annotation: | The project is focused on the experimental study of elementary magnetization processes, especially on domain walls displacements, in powder compacted and composite materials based on 3d transition metals. In this class of magnetic materials, the influence of individual electrically and magnetically non-insulated or isolated particles on the magnetization processes of surrounding particles significantly affects their magnetic properties. In the case of using electro-insulating materials with suitable magnetic materials, the mutual interaction of ferromagnetic particles can be significantly affected. The magnetization processes are in some cases different than that in usual materials prepared by conventional casting. Considering the class of materials prepared by compaction of isolated or non-insulated particles is becoming increasingly important, the knowledge of these peculiarities is useful in developing 3D materials for practical use in electrotechnology. |

The study will be performed on comprehensive model, which will take into account all relevant interactions in rare-earth and transition metal compounds, where besides the spin-independent Coulomb interaction in d and f band also the spin dependent (double exchange) interaction between both bands will be included. For a solution of this model we plan to elaborate new numerical methods, which will be subsequently used in combination with standard methods of quantum statistical physics (DMRG and QMC) to study the above mentioned phenomena. |

| Annotation: | The project is aimed at solving the urgent fundamental problem of the genesis of the so-called of dynamic charge stripes (DCS) - inhomogeneous distribution of conduction electron oscillations - and their influence on the properties of strongly correlated electron systems (SCES). The charge stripes play an important role in the high-temperature superconductivity (HTSC) of cuprates and also underlie the mechanisms responsible for the colossal magnetoresistance in manganites, cobaltites, iron-based HTSCs, etc. Observing directly the effect of DCS on the scattering of charge carriers in the mentioned SCES is very sophisticated due to their complex composition, low symmetry of the crystal structure and high sensitivity to external conditions. Instead, it is suitable to use model SCES. Such model materials are rare earth dodecaborides (RB12) with Jahn-Teller structural instability and electronic phase separation on the nanoscale range, in which the appearance of dynamic charge stripes was reliably determined for the first time both for superconductors (ZrB12, LuB12) and for quantum magnets (R = Ho, Er, Tm). The comprehensive study of DCS will be extended by additional model systems based on hexaborides (RB6) and frustrated quantum magnets based on rare earth tetraborides (RB4), and will includes the influence of external extreme conditions such as very low temperatures, high magnetic fields and pressures. |

| Annotation: | Superconducting materials have become an integral part of the latest technologies such as quantum computers, single-photon detectors, magnetic resonance, SQUID, etc. Achieving room-temperature superconductivity is no more the only goal, but targeted improvement of superconducting parameters (upper critical field, critical temperature) for application needs is the key. Extreme conditions in the form of very low temperatures, high pressures and reduction dimensions into quasi-two dimensions are very powerful tools in this endeavor. In particular, in case of thin films the superconducting properties can be tuned by several external parameters (e.g. film thickness, substrate, interfaces). The main goal of the project is to improve superconducting parameters of the high-entropy alloys and other materials in the form of thin films in purpose for use in future quantum applications technology. |
