RADIOMAG - Multifunctional Nanoparticles for Magnetic Hyperthermia and Indirect Radiation Therapy
Multifunkcionalizované nanočastice pre magnetickú hypertermiu a nepriamu radiačnú
Program: COST
Project leader: Doc. RNDr. Kopčanský Peter CSc.
Annotation:The Action aims to bring together and to organise the research outcomes from the different participating network members in a practical way to provide clinicians with the necessary input to trial a novel anti-cancer treatment combining magnetic hyperthermia and radiotherapy, also identifying future research objectives upon appraisal of the obtained results. Feedback between the different working groups here is essential, and is expected that the lifetime of this Action proposal will eventually result in a compendium of best practices for magnetic hyperthermia.RADIOMAG will generate new and strengthen the existing synergies between technical advances (thermal imaging / MH), new treatment concepts (combined targeting radiosensitisation and magnetic thermotherapy) and biocompatible coating in order to achieve a breakthrough in the clinical application of magnetic hyperthermia. Due to the complexity of this aim, synergies can only be achieved on a longer time frame, by means of workshops, STSMs, joint publications, common Horizon 2020 research proposals and exchange with other COST Actions (e.g. TD1004, TD1205).

NGP-NET - Non-globular proteins - from sequence to structure, function and application in molecular physiopathology
Neglobulárne proteíny - od sekvencie ku štruktúre, funkcii a aplikácii v molekulárnej fyziopatológii
Program: COST
Project leader: doc. RNDr. Gažová Zuzana CSc.
Annotation:Non-globular proteins (NGPs) encompass different molecular phenomena that defy the traditional sequence-structure-function paradigm. NGPs include intrinsically disordered regions, tandem repeats, aggregating domains, low-complexity sequences and transmembrane domains. Although growing evidence suggests that NGPs are central to many human diseases, functional annotation is very limited. It was recently estimated that close to 40 of all residues in the human proteome lack functional annotation and many of these are NGPs. While a better understanding of NGPs is crucial to fully comprehend human molecular physiopathology, progress has been hampered so far by the lack of a systematic approach to their study.This Action Proposal aims to create a pan-European scientific network of groups that work on NGPs to strengthen, focus and coordinate research in this field. It proposes to develop a novel classification of NGPs by consensus among interested experts that will be showcased on a newly developed web site, along with meetings, training schools and scientific missions on NGP-related topics.

NANOUPTAKE - Overcoming Barriers to Nanofluids Market Uptake ( NANOUPTAKE)
Prekonanie bariiér pre komerčné využitie nanokvapalín (NANOUPTAKE)
Program: COST
Project leader: RNDr. Timko Milan CSc.
Annotation:Nanofluids are defined as fluids that contain nanometre-sized particles with enhanced heat transfer properties. Nanofluids improve the efficiency of heat exchange and thermal energy storage. In addition, nanofluids fall within one of the Key Enabling Technologies (KET) supported by the European Commission. Although some nanofluid commercial applications currently exist, most of the current nanofluids are at Technological Readiness Levels (TRL) 1 to 3. Most of the nanofluids research in COST countries has been conducted by Research, Development and Innovation (R+D+i) centres through national funding. Additional coordinated research and development efforts are required to develop nanofluids up to higher TRL levels and to overcome commercial application barriers. If these barriers are overcome, nanofluids will be an important player in the Value Added Materials (VAM) for the energy sector.The objective of the NANOUPTAKE COST Action is to create a Europe-wide network of leading R+D+i institutions, and of key industries, to develop and foster the use of nanofluids as advanced heat transfer/thermal storage materials to increase the efficiency of heat exchange and storage systems.

Program: Bilaterálne - iné
Project leader: doc. RNDr. Gažová Zuzana CSc.
Annotation:This project is aimed at examining the self-assembly of proteins into amyloid aggregates, one of the hallmarks of AD and other amyloidosis. Accordingly, there is a considerable world-wide interest to identify molecular entities that can influence the amyloid aggregation in order to facilitate the drug development for amyloid diseases. The main goals of the project are to estimate the conditions required for promoting protein misfolding, to determine the cytotoxicity of amyloid aggregates, and to identify the compounds (e.g. small molecules and nanoparticles) that are able to inhibit protein aggregation using in vitro and in silico methods. The bilateral collaboration will allow to combine expertise and experience of both partners in the field of protein aggregation and acquire complex data with aid of complementary approaches, leading to a better understanding of amyloid aggregation mechanisms. The use of equipment provided by both institutions will offer a solid background for team members in order to publish their results at conferences and in journals. 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 NTU and SAS and work as an international scientific research group.

The obtained theoretical outcomes will contribute to a deeper understanding of exotic quantum states of spin and electron systems such as being for instance different kinds of quantum spin liquids as well as quantum states with a subtle long-range order of topological character or with a character of valence-bond solid. The project will significantly contribute to a clarification of unconventional magnetic behavior of selected low-dimensional magnetic materials and thus, it will have significant impact on a current state-of-the-art in the field of condensed matter physics and material science. On the other hand, a detailed investigation of quantum entanglement will establish borders of applicability of the studied spin and electron systems for the sake of quantum computation and quantum information processing. Another important outcome of the project is to clarify nontrivial symmetries in tensor states of the strongly correlated spin and electron systems affected by either position dependent interactions or changes in lattice geometries, which induce phase transitions of many types.

GONanoplatform - Graphene-based nanoplatform for detection of cancer
Grafénová nanoplatforma na detekciu rakoviny
Program: APVV
Project leader: Ing. Koneracká Martina CSc.
Annotation:This project proposal reflects current technological progress and new opportunities in biomedical applications of graphene-based sensors. Our main goals include the design and development of a graphene oxide multifunctional nanoplatform (GO-MFN) for the detection of tumor cells. In the first step, the development of graphene oxide nanoflakes of appropriate size functionalized by monoclonal antibody is planned. For sensing the tumor cells, GO-MFN of 100 nm size able to interact with a single cell will be prepared. Magnetic nanoparticles added to GO-MFN will enable the inspection of deep tissues by nuclear magnetic resonance. The degree of oxidation of GO, type of the functional groups, optimal functionalization with covalently bound monoclonal antibodies and magnetic nanoparticles, are the most important technological steps. The analysis of the basic interactions related to tumor sensing will be conducted in vitro on 2D and 3D cell models up to the proof-of-principle stage that will be directly applicable to laboratory and preclinical testing. The GO-MFN interaction with the cell membrane and with the cell interior will be analysed with subcellular resolution. Such an approach will bring original knowledge and a detailed understanding of the tumor sensing process that is important 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 to biomedicine and combining excellent science and the most sophisticated nano and bio-engineering. The involved partners possess key skills, infrastructure, antibodies and tumor models, and are highly motivated to reach the project goals.

Complementary study of superconductivity of selected materials
Komplementárne štúdium supravodivosti vybraných materiálov
Program: VEGA
Project leader: RNDr. Kačmarčík Jozef PhD
Annotation:Since the discovery of the two-gap superconductivity in MgB2 almost 15 years ago, a continuous search for other examples of this special feature is maintained. Another interesting issue of these days in condensed matter physics is investigation of materials with competing orders, where for example superconductivity coexists or compete with magnetic ordering or charge density waves. Within the project we will focus on study of several representatives of these groups – we will confirm or disconfirm presence of two energy gaps in LaRu4As12 and Bi2Pd, we will explore competing orders in CuxTiSe2 and CeCoIn5 and we will address spatially constrained superconductivity in granular doped diamond. Clarification of their superconducting mechanism could shed some light on other superconducting materials. We will also work on development of new experimental methods – implementation of a resistive calorimeter and mastering and further enhancement of local magnetometry using Scanning Hall-probe microscope.

The mechanical analysis will be concentrate on examination of elastic properties, like Young modulus, Poisson ratio, thermal expansion as well as the sample hardness. The obtained results will contribute to a deeper understanding of mechanisms leading to the unconventional phenomena in two-dimensional magnetically frustrated spin system and will help us to better understand the role of quantum fluctuations in these materials.

In order to achieve this aim we will investigate novel quantum materials which can improve properties of quantum devices. Therefore, the fundamental research of new topological materials including topological insulators and superconductors will thus be a logical and integral part of our project.

Magnetoelektrický a magnetokalorický jav v exaktne riešiteľných mriežkovo-štatistických modeloch
Program: VEGA
Project leader: RNDr. Čenčariková Hana PhD
Annotation:Magnetoelectric and magnetocaloric effects will be examined in detail with the help of exactly solvable lattice-statistical models including Ising spin systems, Ising-Heisenberg spin systems and coupled spin-electron systems, which consist of localized Ising spins and delocalized electrons. The primary goal of the project is to explore an influence of external electric field on basic magnetic properties and an influence of external magnetic field on basic thermodynamic properties of the studied lattice-statistical models. A response of magnetic system on a change of external electric and magnetic fields will be investigated mainly in a vicinity of phase transitions (including quantum ones), where particularly interesting behaviour can be expected. The rigorous theoretical results will contribute to a deeper understanding of both studied cooperative phenomena, what enables to propose a subsequent optimalization of technologically important properties of multifunctional materials and magnetic refrigerants.

MICROMANIP - Image analysis of microscopic particles in the automation of optical manipulation techniques applicable in mikro/nanorobotics.
Obrazová analýza mikroskopických častíc pri automatizácii optických manipulačných techník aplikovateľných v mikro/nanorobotike.
Program: APVV
Project leader: Doc. Ing. Tomori Zoltán CSc.
Annotation:Mikromanipulation based on the laser optical traps represents a progressive method of basic research in the physical, chemical and biomedical sciences. An analogy between the optical manipulation and the robotics evokes exploitation of the artificial intelligence algorithms (computer vision, machine learning, planning of trajectories, etc.). According to some authors, the use of these methods in combination with physical models has led to the significant increase of the effectiveness compared to the classic optimization (up to 1000 times in SVM classifier trained in advance using the Lorenz-Mie scattering light model). The aim of the project is to use a similar philosophy for the experimental tasks solved in our laboratory - cells sorting and fusing, their physical properties measurement and etc. Using the apparatus for 2-photon polymerization we plan to manufacture microrobotic instruments controlled by the optical tweezers traps, e.g. a mikrorobotic arm (gripper). As continuity with our previous project, we would improve the interactive control of optical tweezers via NUI interface (using the position of the fingers and gaze, voice, gestures). This interface should be functional not only locally, but also remotely over a network connection.

Functional and Structural Insights into the Phospholipid-Protein Interaction during Oxidative Stress
Oxidačný stres a fosfolipidovo-proteínové interakcie: funkčné a štrukturálne dôsledky
Program: VEGA
Project leader: MUDr. Musatov Andrey DrSc.
Annotation:Mitochondria play a critical role in cells metabolism and mitochondrial dysfunction has long been implicated in age-related neurodegenerative diseases. One currently accepted theory is that damage to mitochondria, the main source of reactive oxygen species (ROS), initiates these diseases. In fact, when ROS levels overpower the cell’s defenses (oxidative stress), proteins, nucleic acids and/or lipids are irreversibly damaged. Particularly important is that oxidative stress disrupts or modifies the protein-lipid interactions what is one of the essential features of normal cell operation. Such disruptions could be a decisive factor leading to ROS-induced diseases. To test this hypothesis and clearly elucidate the links between mitochondrial oxidative stress and cells dysfunction we propose to investigate both, (i) the role of phospholipid modification in ROS-induced damage to mitochondrial electron transport Complex IV, and (ii) the role of phospholipids and oxidatively modified phospholipids in amyloidogenesis.

Project leader: Mgr. Szabó Pavol CSc.
Annotation:The project aims at understanding the problem of how superconductor transforms to insulator at increased disorder. The questions of what is the force driving the superconducting transition temperature to lower values in ultrathin superconducting films and what is the mechanism of the quantum phase transition between superconducting and insulating states will be addressed experimentally as well as theoretically. The superconducting films of various content with thicknesses down to few atomic layers as well as the nanostructures and resonators on their basis will be prepared. Transport, microwave and optical properties of these objects will be investigated. By means of the subkelvin scanning tunnelling microscope the spectral maps of the quasiparticle density of states at ultralow temperatures and in high magnetic fields will be measured. We will explore possibilities to prepare sensitive photon detectors and amplifiers based on ultrathin disordered superconducting films for the spectroscopy in physics, chemistry and biology. Dynamics of the surface states in another macroscopic quantum object, the superfluid 3He which is the topological insulator at ultra low temperatures, will be investigated experimentally as well as theoretically. The objective is to elucidate the dynamics of surface bound excitations in superfluid 3He by means of mechanical resonators and resolve if the excitations can be identified with the long searched Majorana fermions. By experiment the recent question if samarium hexaboride is a topological insulator will be addressed.

Supramolecular complexes of biomacromolecules
Supramolekulárne komplexy biomakromolekúl
Program: VEGA
Project leader: RNDr. Valušová Eva PhD.
Annotation:Cells have numerous examples of nonmembrane-bound compartments containing many biomacromolecules. However, their physicochemical properties play an important role in a number of biological processes, but their complex biochemistry still remain poorly understood. These granules exhibit liquid-like behavior. Two or more biomacromolecules that interact with each other form liquid droplets in which their concentration is higher than in the surrounding aqueous medium. Furthermore, high concentrations of solutes, ions and also some low - molecular weight molecules contribute to mesoscale organization in certain biological systems. The project is devoted to address processes allowing preparing and characterization physicochemical properties of supramolecular complex models of nonmembrane-bound compartments and will also concentrate on mechanisms that occur during these processes.

Study of universal properties of diffusion proceses in turbulent environments
Štúdium univerzálnych vlastností difúznych procesov v turbulentných prostrediach
Program: VEGA
Project leader: RNDr. Jurčišin Marián PhD.
Annotation:One of the basic attributes of macroscopic physical, chemical, biological, and also social-economical and environmental systems is their stochasticity. This fact is the main reason for present intensive scientific interest about various stochastic systems. Advection of various admixtures in random environments, turbulence and magnetohydrodynamic turbulence, or crossing of cosmic particles through interstellar space, are typical examples. The importance of intensive Investigation of these problems is dictated by need for fundamental understanding of the physical nature of phenomena which are involved in them, as well as from the point of view of their potential future applications in technical praxis. The aim of the project is the study of the anomalous scaling of structure and correlation functions of fluctuating fields in turbulent systems without and with symmetry breaking, as well as the study and the calculation of universal characteristics of such turbulent systems.

NANOSIMKA - Effects of nanoencapsulated simvastatin on cardiovascular system in experimental metabolic syndrome
Účinok nanoenkapsulovaného simvastatínu na kardiovaskulárny systém pri experimentálnom metabolickom syndróme
Program: APVV
Project leader: Ing. Závišová Vlasta PhD.
Annotation:High level of cholesterol in the blood increases the risk of heart and vascular diseases. Simvastatin reduces cholesterol production in the liver thus reduces the blood cholesterol level. Long-term use of statins has been associated with the occurrence of side effects, which in addition increase with increasing their dose. In particular, the statin side effect include mainly inhibition of the endogenous synthesis of CoQ10 - basic cofactor for ATP synthesis and paradoxically activation of PCSK9 - an important enzyme for the synthesis of LDLcholesterol. The project aims to increase the bioavailability of simvastatin in the liver, thus reducing the daily dose and consequently to prevent the reduction of CoQ10 levels as well as to block the activation of PCSK9. In order to achieve this this aim, nano-encapsulated simvastatin together with nano-encapsulated CoQ10 or PCSK9 inhibitor, or in the polymer with antioxidant properties will be prepared, tested and applied. This ensures the targeted transport of simvastatin to the liver simultaneously with CoQ10, or inhibitor of PCSK9, or simultaneous increase in antioxidant capacity. In the case of successful results the proposed project may uncover new possibility of using nanocarriers for the treatment of metabolic and cardiovascular diseases.

The role of surface states in samarium hexaboride and other valence-fluctuating systems exhibiting metal-insulator transition
Úloha povrchových stavov v hexaboride samária a iných zmiešanovalenčných systémoch vykazujúcich prechod kov-izolátor
Program: VEGA
Project leader: RNDr. Baťková Marianna PhD.
Annotation:Samarium hexaboride (SmB6) represents an important model system exhibiting metal-insulator transition. A mysterious property of this valence fluctuating semiconductor is that at lowest temperatures it does not reveal divergency of electrical resistivity, but behaves as a metal. SmB6 is nowadays intensively studied also as a possible topological insulator, while metallic topologically protected surface is considered to be a reason of absence of insulating ground state. However, the latest results provide evidence about trivial surface states in SmB6. The project aims to evaluate the role of surface states in electrical conduction of SmB6 by investigating SmB6 thin films, to evaluate relevance of the scenario of topological insulator and other alternative approaches to explain electrical conductivity in SmB6, thus to contribute to understanding the nature of electronic transport in SmB6 and similar systems.

Effect of extreme environment (magnetic field, pressure, temperature) on the anomalous behavior of the ground state and phase transitions in strongly correlated materials.
Vplyv extrémnych podmienok (magnetické pole, tlak, teplota) na neobvyklé chovanie základného stavu a fázové prechody v korelovaných látkach
Program: VEGA
Project leader: RNDr. Mihálik Matúš PhD.
Annotation:Nowadays, the trend in research of rare-earth intermetallic compounds is the shift of the interest towards the physical phenomena like Kondo behavior, non-Fermi liquid behavior, or quantum critical point. It has turned out that these exotic types of behavior can be observed in Ce, Yb, or U-based compounds. During the project we will prepare and characterize polycrystals and single crystals from Ce – Ni – Ge; Ce – Co – Ge, U - Ni – Ge and U – Co – Ge ternary systems. The main objective of our project is search for quantum criticality in these antiferromagnetic and ferromagnetic systems and generating quantum fluctuations by suitable chemical doping (Co-Ni substitution; or Ge-Si substitution), high pressure and magnetic field. The additional objective is seeking for the novel materials targeted U-based ternary intermetallic compounds.

Influence of extreme conditions on strongly correlated electron systems
Vplyv extrémnych podmienok na silne korelované elektrónové systémy.
Program: VEGA
Project leader: Doc. RNDr. Gabáni Slavomír PhD.
Annotation:Strong correlations between free (conduction) and bound (localized) electrons in a condensed matter can be change or modified by extreme conditions (very low temperatures, high pressures and magnetic fields), what often leads to the creation of new/exotic states/effects in these materials. In this proposal, we will experimentally study the newest open problems in strongly correlated electron systems (SCES), as surface conductivity in topological Kondo insulators, dynamics of frustrated antiferromagnets, Kondo vs. spin-polaron model in spin glasses, superconductivity under pressure. All this will be a very time-consuming research on new-produced samples.

Development of new procedures for the reconstruction and analysis of the data from the proton-proton collisions at the LHC
Vývoj nových postupov pre rekonštrukciu a analýzu dát z protón-protónových zrážok na urýchľovači LHC
Program: VEGA
Project leader: RNDr. Stríženec Pavol CSc.
Annotation:Theoretical as well as methodological contribution to studies of proton interactions at LHC accelerator, which was just upgraded to a new, so far the highest energy of proton-proton collisions, is proposed in this project. The project goal is to contribute to the improvements of existing reconstruction and analysis procedures, as well as to bring up new aspects from theoretical and methodological points of view. The main contribution to methodology will be the improvement of the hadronic calibration of the ATLAS calorimeter. Contribution to the accuracy improvement of b-jet charge calibration is also foreseen. We assume three main contributions to the analysis, namely improvements of the top-quark charge measurement, searches for Higgs boson and searches for Standard Model (SM) extensions, as well as to obtain improved data to study Bose-Einstein correlations between the pions produced in proton collisions.
