Annotation:A common feature associated with most of neurodegenerative diseases, including Alzheimer’s disease is the formation of extended, β-sheet rich amyloid fibrils. Today, amyloid-related diseases are incurable and the treatment is only symptomatic without feasibility to stop or substantially delay the progressive consequences of the diseases. Magnetic nano/micro-particles based on clinoptilolite-type of natural zeolite (CZ) jointly developed are expected to serve synergistic therapy approaches act as carriers for controlled drug delivery/release, imaging and local heating in biological systems, that can effectively decompose the amyloid-like fibrillar structures. The micro and mesopores of the natural zeolite can serve as containers for delivering various drugs to the target site to release. Magnetic CZ (MCZs) will improve drug delivery process, real-time monitoring of drug distribution surrounding a targeting side of tissue, as well as the subsequent effects of the therapeutics on the progression of diseases. In addition, fluorescent MCZs in combination with ultrasonic, magnetic or laser irradiation effects will provide hyperthermia and photoreaction to achieve both diagnosis and therapy. The Taiwanese research team has been deeply cultivated in temporal focusing multiphoton microscopy (TFMPM), which imaging frame rate can achieve up to a hundred hertz. We will use the deep learning method to improve the imaging frame rate for real-time biomedical analysis. Within this project, animal models (including genetic rodent models) will be utilized to develop a theranostic system for for inhibition and destruction of amyloid aggregates and super-resolution imaging of MZC induced amyloid aggregate inhibition/destruction effects by state-of-art temporally and spatially super-resolution 3D imaging technology.

Annotation:Amyloid fibrils of amyloid β (Aβ) peptides are a neuropathological feature of Alzheimer's disease (AD). AD is one of the world's fastest-growing neurological diseases with substantial economic and societal impact, but no cure is currently available. Therefore, the exploration of novel treatment approaches is in high demand. The project's main objective is to study the ability of azobenzene molecules to affect targets associated with the amyloid cascade of AD pathogenesis. The project will employ the lever-like potential of azobenzene molecules to dissociate fibrillar aggregates of Aβ peptides and inhibit the proteolytic activity of β-secretase. We will integrate in vitro, in silico, and cells workflow to find a possible alternative therapy against this devastating disease. 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 the Polish and Slovak Academies of Sciences and gain new experience by working in an international scientific environment.

Annotation:Cancer is still one of the leading causes of death worldwide, therefore significant research and innovation efforts are still needed to find new materials and methods for better cancer diagnosis and treatment. Magnetic nanoparticles (MNPs) appear to be a very promising material for use in many medical fields, such as in nanosurgery they can be used to kill tumor cells by increasing drug concentration in target cells in combination with hyperthermia as well. The presented project is focused on the development of new nanoconstructs labeled by radionuclide as a potential theranostic agent for radiotherapy and diagnostics. The first step to achieve the desired goal will be the synthesis of nanoconstructs consisting of self-heating magnetic nanoparticles coated with various biocompatible substances, which will exhibit the desired bioactivity as well. The prepared nanoconstructs will be studied by several physicochemical methods, and their stability and suitability for magnetic hyperthermia, i.e. the ability to produce heat in an alternating magnetic field, will be monitored. In the second step, nanoconstructs with the best properties will be radiolabeled with therapeutic 177Lu and diagnostic 99mTh radionuclides to prepare radioactive nanoconstructs for dual therapy and diagnosis. In the next step, in vitro toxicity testing of nanoconstructs labeled with radionuclides will be performed. The prepared magnetic magnetic nanostructured materials labeled with radionuclides will contribute to the improvement of diagnostics and therapy of cancer diseases. The project is based on a complex multidisciplinary approach, from physics, chemistry to biochemistry and biomedicine. The involved partners possess key skills, infrastructure and are highly motivated to achieve the project goals.

Project leader: Ing. Baláž Ján PhD.,
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:Turbulent behavior belongs among basic properties of various macroscopic physical, chemical, biological, social-economical, financial, as well as environmental systems. Typical well-known examples of turbulent motions are various atmospheric phenomena (tornadoes, hurricanes, cyclones, etc.), turbulent streams in rivers and oceans, and turbulent motions in electrically conductive environments (motion of the outer earth core, solar wind, etc.) . The main task of theoretical investigations of turbulent systems is, first of all, the understanding of fundamental physical properties of turbulent flows that are common for all turbulent systems and which could potentially be applied in technical praxis in the future. In this respect, the main aim of the project is the investigation of the influence of breaking of various symmetries of developed turbulent environments on the properties of the anomalous scaling of correlation functions of fluctuating fields as well as on universal characteristics of turbulent systems.

Annotation:The development of activities in the field of hydrogen technologies was also supported by the European Commission in the strategic document "Hydrogen Strategy for a Climate Neutral Europe". Today, Slovakia has suggested own national hydrogen strategy. Already in 2015, the National Hydrogen Association has founded to support research, implementation and use of hydrogen technologies. The Hydrogen Technology Center is being established in Košice with the main "Power-to-Gas" concept using renewable power energy sources with no negative impact on human life and without dependence on fossil fuels. A significant source of hydrogen is water and the electrolysis of water is the most promising technology for hydrogen production. However, before it can be recognized as an economically significant resource for large scale application with an exceptional energy potential, the simple, efficient, and secure methods of hydrogen retrieval have to be developed. For the time being, the most efficient electrocatalysts in terms of overpotential for hydrogen evolution reaction (HER) are noble metals. Unfortunately the high cost and scarcity of noble metals motivate the scientists to find the rival low-cost alternatives. Intrinsic structures of TMP meet the criteria of outstanding electrocatalysts that could further improve their HER performance in membrane electrode assembly. Excellent dispersity of electrocatalysts allows full use of active sites on catalysts to participate in electrode reaction to improve the electrocatalytic efficiency. Therefore, the main challenge in this project is to reduce the production cost of HER and at the same time to maintain the high efficiency of polymer electrode water electrolysis. Substantial aim of the project will be devoted to improve the PEM water electrolysis components mainly electrode materials based on modified carbon fibers electrocatalysts result in the technology which should be more approached to commercial markets.

MNPs functionalization and drug conjugation will be optimized and studied by physicochemical methods such as UV/Vis and IR spectroscopy, microscopy, calorimetry or magnetic measurements. In the next phase, the conjugate will be analyzed by MRI and compared with the properties of commercially available MRI contrast agents. In the third step, the relevant ARDS model will be created, and the conjugate will be applied to the lungs. Finally, the conjugate will be imaged using optimized MRI techniques to study the drug distribution in the lungs in ARDS. The output items of the project have a direct application potential for clinical practice.

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.

Project leader: RNDr. Rajňák Michal PhD.
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.

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.

Unraveling the early events of protein amyloid aggregation - from mechanism to therapy

Objasnenie počiatočných štádií amyloidnej agregácie proteínov - od mechanizmu k terapii

Evidence number:2/0176/21
Program: VEGA
Project leader: doc. RNDr. Gažová Zuzana DrSc.
Annotation:Structural changes of poly/peptides leading to the formation of amyloid aggregates are associated with incurable diseases, like Alzheimer's disease or diabetes. While the general mechanisms of fibril formation and their characterization are well reported, the early events during poly/peptide fibrillation are still unclear. The project is focused on understanding the early events mechanisms leading to the formation of pre-fibrillar (partially un/folded intermediates, nuclei, oligomers) and fibrillar amyloid aggregates of selected globular and intrinsically disordered proteins. Our focus will be the study of the kinetics of pre-fibrillar structures formation, their morphology, and cytotoxicity, under various experimental conditions, and in the presence of selected interacting partners (small molecules, nanoparticles). The obtained results will contribute to understanding the early events of amyloid aggregation and identifying the inhibitors with therapeutic potential for amyloid diseases.

PRESPEED - Perspective electronic spin systems for future quantum technologies

Evidence number:APVV-20-0150
Program: APVV
Project leader: RNDr. Vargová Hana PhD.
Annotation:The project is aimed at a comprehensive understanding of possibilities and limiting factors of electron spin systems for a quantum computation and quantum information processing, which will be investigated by the combination of advanced analytical and numerical methods including among others exact mapping transformations, localized-magnon theory, exact diagonalization, tensor-network methods, density functional theory, Monte Carlo simulations and density-matrix renormalization group method. In particular, we will examine the possibility to stabilize a bipartite and multipartite entanglement as a genuine quantum phenomenon needed for a quantum computation and quantum information processing at least up to temperature of liquid nitrogen or preferably room temperature. We will also explore the capability of the pulsed electron spin resonance for the spin-qubit manipulation. Quantum spin systems with topologically protected edge states eligible for a topological quantum computation will be investigated in detail together with a few selected quantum spin chains studied in connection with the implementation of a quantum teleportation. Frustrated Heisenberg spin systems supporting either the presence of a nontrivial skyrmion phase or magnon-crystal phases will be investigated in connection with the possibility to store a quantum information or to implement more complex quantum circuits. Heterostructures composed of atomically thin layers coupled by van der Waals forces will be examined with respect to a superconducting pairing and topological quantum computation. The studied electron spin systems will be either motivated by the effort to understand unconventional behavior of existing real magnetic materials or will be supplemented by the respective proposals for their experimental realization.

Annotation:The proposal aims to approach the research of liquid crystals doped with nanoparticles of different kind from a novel perspective of the self-organization that has an indisputable importance covering all fields of natural sciences, and has also a deep impact in social sciences. In such composite systems a subtle interplay among the nanoparticles, the self-assembling matrix and the topological defects commands the self-organization process. We will focus on the electric/magnetic field induced self-organization in such systems experimentally on different length scales by investigating the processes in different phases, isotropic, nematic, cholesteric with the anticipation that our results can be exploited in applications such as guided material transport, magnetic/electric switches/sensors, chemical/biosensors, in microfluidic/lab-on-a-chip devices, etc. We are convinced that systematic studies in this topic may change fundamentally current knowledge.

Evidence number:APVV-21-0333
Program: APVV
Project leader: doc. Ing. Tomori Zoltán CSc.
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.

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.

STRIPEX - Influence of dynamic charge stripes on quantum magnets and superconductors in extreme conditions

Vplyv dynamických nábojových pásov na kvantové magnety a supravodiče v extrémnych podmienkach

Duration: 1. 7. 2024 - 30. 6. 2028
Evidence number:APVV-23-0226
Program: APVV
Project leader: doc. RNDr. Gabáni Slavomír PhD.
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.

Enhancement of superconducting parameters in high-entropy alloy thin films

Project leader: RNDr. Pristáš Gabriel PhD.
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.
