Atmospheric electricity and secondary cosmic radiation
Atmosferická alektrina a sekundárne kozmické žiarenie
Program: Inter-academic agreement
Project leader: Mgr. Langer Ronald
Annotation:A continuation of recently started joint investigation into the relation between atmospheric electricity and dynamics, secondary cosmic radiation and space weather is proposed. A special focus will be paid to events that occur during thunderstorms, e.g., to enhanced count rates that were observed in particle detector SEVAN during periods of large electric fields, and search for a possible detection of particles during individual atmospheric discharges. The study will be based on measurements of electrostatic field, electromagnetic radiation from lightning, meteorological data, and energetic particles and gamma-rays on Lomnický peak. A further improvement and extension of measurement setup around Lomnický peak is anticipated. Atmospheric electric field will also be measured at several places in the Czech Republic. The main goal of the proposed project is a better understanding of mechanisms that couple atmospheric electricity and thunderstorms with energetic particles (radiation) and space weather. Both statistical approach and analysis of individual events will be performed.

Dynamical study of formation/destruction of protein amyloid aggregatess targeted by magnetic zeolite nanocomposites
Dynamické štúdium amyloidnej agregácie proteínov pomocou magnetických zeolitových nanočastíc
Program: JRP
Project leader: doc. RNDr. Kopčanský Peter CSc.
Annotation:Abnormal protein aggregation and accumulation of formed fibrils are characteristic features for a range of, if not all, neurodegenerative disorders such as Alzheimer’s, Huntington’s, Parkinson’s, as well as non-neuropathic amyloidosis. Nanoparticles (NPs), attributed to its particularities in sizes, chemical composition and surface properties, have already been found effective in influencing amyloid fibrils. Our preliminary results acquired on amyloid fibrils incubated with in-laboratory synthesized Fe3O4 nanoparticles (MNPs) indicated reductive potential of MNPs on formation of amyloid fibrils, and also suggested facilitation of inhibiting preformation and eradication of amyloid fibrils may be plausible when the fibrils are exposed to external radiation in presence of MNPs. Also, with our previously reported photoluminescence properties of natural zeolite (CZ) which is a promising material for biomedicine and pharmaceutics due to its non-toxicity, thermal stability, expanded surface area, and exceptional ability to adsorb various atoms, organic molecules and nanoparticles into micro- and mesopores, we plan to apply the MNPs with CZ, developing multiphoton excitation microscopy (MPEM), and other appropriate instruments to establish the dynamical investigation of amyloid fibril formation and remodeling in real time. Prior to in vivo experiment, cytotoxicity in different type of cells and animal models such as zebrafish and mice will be evaluated.

Flexible Magnetic Filaments: Properties and Applications
Flexibilné magnetické vlákna: Vlastnosti a aplikácie
Program: ERANET
Project leader: doc. RNDr. Kopčanský Peter CSc.
Annotation:Different technologies for synthesis of flexible magnetic filaments are developed. These include linking magnetic micro-particles by DNA, attaching magnetic nanoparticles to polyelectrolyte bundles, extraction of magnetosomes from magnetotactic bacteria and other. Flexible magnetic filaments are interesting for applications as self-propelling microdevices(for targeted transport), micro-mixers (for microfluidics), different sensors(micro rheology). Numerical algorithms for predicting their behavior in magnetic fields of different configurations will be developed, including algorithms based on curve dynamics, lattice Boltzmann method, Brownian dynamics. Obtained numerical results will be compared with experimental results of measurement of flows fields around magnetic filaments, their buckling instabilities. As a result new technology will be developed for DLS measurements giving access to characteristics of translation and rotational motion of string like magnetic micro-objects.

Complementary analytic methods for the determination of the biodistribution of the magnetic nanoparticles
Komplementárne analytické metódy na určenie biodistribúcie magnetických nanočastíc
Program: Bilateral - other
Project leader: Ing. Koneracká Martina CSc.
Annotation:The main objective of the proposed project is focused on the design and synthesis of magnetic nanoparticles as a potential candidate for hyperthermia, transport delivery and chemotherapy/radiotherapy treatment. The special effort is devoted to their biodistribution investigation due to the combination of complementary physico-analytical methods. Basic concept includes procedures (i) to obtain well-defined magnetic nanoparticles available for medical applications, (ii) to characterize the products under welldefined and reproducible conditions, (iii) to develop proper combination of physico-analytical methods towards detailed biodistribution analyses. In the context of the proposed project, special effort will be focused on the systematic study of the optimization of magnetic nanoparticles synthesis with suitable functional properties and sufficient response to the selected analytical methods for determination of their biodistribution. It is expected that such attitude will result in protocol for preparation and study biodistribution of magnetic nanoparticles in as low as possible concentrations that could significantly decrease undesirable side effects of treatment. Besides that, such project will significantly contribute to the (i) bilateral cooperation and transfer of knowledge between experts in chemistry, physics, biology and pharmacy; (ii) the optimization of the real structure and bioaccumulation investigation of the prepared products; (iii) presentation and publication of common results on high impact factor journals and important international conferences; (iv) networking/base for further cooperation in highly attractive scientific field regarding biophysics/nanomedicine.

Metallic geometrically frustrated systems
Kovové geometricky frustrované systémy
Program: Inter-academic agreement
Project leader: doc. RNDr. Gabáni Slavomír PhD.
Annotation:The principal aim of this project is to establish the microscopic anisotropy parameters and the relevant terms for the magnetic interaction in MGFS. Despite significant experimental and theoretical work, such parameters are unknown for the compounds (e.g. TmB4, HoB4) which form a Shastry Sutherland lattice (SSL) as well as for the highly symmetric face centered cubic (fcc) lattice based systems (e.g. HoB12). The experimental approach will be magnetisation measurements as a function of field direction, neutron diffraction combined with modelling techniques like WIEN2K, McPhase or SpinW. The oscillatory RKKY exchange interaction parameters are expected to be susceptible to applied pressure as well as to alloying. Suitable methods and oriented samples of rare earth borides are available. Crystal field anisotropy is theoretically described by a multipole expansion of the electric field. The crystal field level splitting parameters will be determined from magnetisation and specific heat data, as a function of field direction, as well as from inelastic neutron diffraction on powder samples, typically using software like McPhase. The goal of this part is a description of anisotropy of TmB4, HoB4 and the symmetric fcc – counterparts HoB12 and TmB12. The second set of parameters needed for understanding of the Hamiltonian are the magnetic interactions. They will be determined from the dispersion relations measured using neutron spectroscopy on HoB4 and HoB12 along different crystallographic directions and in applied magnetic field. These parameters depend on details of the RKKY interaction which as a cross check can also be obtained from first principles, using packages like WIEN2K. This type of experiments will be carried out at the HZB Berlin on isotopically enrich Ho11B4 and Ho11B12 samples, which are available and first testing experiments were already carried out. We intend to verify results by high pressure experiments (we assume pressures up to 10 GPa in diamond pressure cells) which is associated with the increase of itinerant electron concentration in MGFS, and thus with the change of parameters as well as changes of critical fields and temperatures. This aim will cover MGFS based on the SSL structure as well as systems based on the fcc structure. Another option to verify results is alloying. We will study the effect of substitution of magnetic ions like Tm3+ and Ho3+ ions by nonmagnetic Lu3+ ions. Necessary devices and samples for this research are available.

Cosmic rays as observed at two high mountain observatories: BEO Moussala and Lomnicky Stit
Kozmické žiarenie pozorované na dvoch vysokohorských observatóriách: Moussala a Lomnický štít
Program: Inter-academic agreement
Project leader: Mgr. Langer Ronald
Annotation:The main idea of the project is bilateral cooperation between two European high mountain stations (Lomnický štít, Slovakia and BEO Moussala, Bulgaria) in the field of solar phenomena (or extreme space whether events) as Forbush decrease (FD) and modulation effects on galactic cosmic rays (GCR), and their possible correlation with meteorological parameters. A Forbush decrease is a rapid decrease in the observed galactic cosmic ray intensity following a coronal mass ejection (CME). It occurs due to the magnetic field of the plasma solar wind sweeping some of the GCR away from Earth. The FD is usually observable by particle detectors on Earth within a few dаys аfter the CME, аnd the decrease takes place over the course of a few hours. Over the following severаl dаys, the sоlar cоsmic ray intensity rеturns tо nоrmal. Peer reviewed article (2) from 2009 found that low clouds contain less liquid water following Forbush decreases, and for the most influential events the liquid water in the oceanic atmosphere can diminish by as much as 7%. Further work (3, 4) found no connection between Forbush decreases and cloud properties until the connection was found in diurnal temperature range (5) and since confirmed in satellite data (6). 8NM64 neutron monitor measures continuously cosmic rays at Lomnický Štít (2634 m a.s.l., rigidity cut-off ~4GV) with high statistical accuracy (average count rate ~440 s-1) since December 1981 (7). The muon telescope at BEO Moussala (2925 m a.s.l., rigidity cut-off ~6.3 GV) is in operation since August 2006. The averaged yearly data show good anti-correlation with the averaged sun-spot number for the period August 2006 – June 2017 (to be published elsewhere), several FDs were also detected (8, 9 and 10). The CR data from the two stations will be analyzed for 11 years period and correlations between their variations and meteorological parameters will be investigated (11, 12). The effect of strong electric field around the time of the thunderstorms will be searched both at Moussala and at Lomnický štít with help of similar detector systems SEVAN being in operation at both stations as it was done recently for Lomnický štít (15). This may be especially importance because of different shape of surface at the stations (Lomnicky stit is rather sharp in altitude profile). The physics behind climate change is still a subject of discussion and in need of further analysis (13). The standard method of examining the effect of CR on CC is to search for a correlation of the time series of the two quantities: CC and CR (14). There are numbers of factors which need to be kept in mind, as follows: the presence of a correlation between CR and CC; the nature of CC; Global, spatial variability; Global temporal variability; Altitude differences. In what follows we examine the comprehensive meteorological data from the Lomnicky stit (LS) and BEO Moussala mountain observatories in comparison with Global data to answer the question: is there support for the hypothesis that CR contribute significantly to the local climate, by way of enhanced cloud cover?

NANOSCALE COHERENT HYBRID DEVICES FOR SUPERCONDUCTING QUANTUM TECHNOLOGIES
NANOSCALE COHERENT HYBRID DEVICES FOR SUPERCONDUCTING QUANTUM TECHNOLOGIES
Program: COST
Project leader: prof. RNDr. Samuely Peter DrSc., akademik US Slovensko
Annotation:Superconducting technologies are prime candidates to ripen quantum effects into devices and applications. The accumulated knowledge in decades of work in understanding superconductivity allows scientists now to make experiments by design, controlling relevant parameters in devices. A new field is emerging whose final objective is to improve appliances taking advantage of quantum effects, be it for dissipationless transport of current, generation of high magnetic fields, sensors or quantum information. The field will impact crucial areas for societal development, including energy, transport, medicine or computation. Quantum behavior is controlled by using hybrids of superconductors with magnets, insulators, semiconductors or normal metals. Traditionally, the scientific and technical communities working in superconductivity are spread across projects from different calls, whose activities put Europe at the frontier of research. The present Action aims to address the pressing need for a common place to share knowledge and infrastructure and develop new cooperative projects.To this end, we have set-up a program including networking activities with an open, proactive and inclusive approach to other researchers and industry. We will develop the concept of a Virtual Institute to improve availability of infrastructure and knowledge, and focus on contributing to gender balance and the participation of young researchers. The proposal aims to avoid duplication of resources and skills in a subject traditionally dominated by small groups working independently. This will optimize European efforts in this area and uncover our full potential, thus maintaining and developing Europe’s leading position in superconducting quantum technologies.

New MAGnetic Biomaterials for Brain Repair and Imaging after Stroke
Nové magnetické biomateriály pre obnovu mozgu a zobrazovanie po mozgovej príhode
Program: ERANET
Project leader: doc. RNDr. Kopčanský Peter CSc.
Annotation:By engineering novel magnetic nano-biomaterials we will achieve tissue repair in the context of an ischemic event. We will take advantage of nanotechnology to deliver therapeutic growth factors, secreted by progenitor cells, into the injured brain. According to the World Health Organization, 15 million persons suffer a stroke worldwide eachyear. However, the only available treatment is the acute thrombolytic therapy (pharmacological or mechanical) which is being administered to less than 10% of stroke patients due to strict selectioncriteria. In contrast, neuro-repair treatments could offer the opportunity to include most strokepatients by extending the therapeutic time window. MAGBBRIS will demonstrate that growth factors, secreted by endothelial progenitor cells, with proved potential to induce tissue repair, can be encapsulated in magnetic biomaterials and be successfully and safely transplanted into mouse brains to induce tissue repair. In the ischemic brain, the secretome will be retained by an external magnetic field in the vasculature, improving vascular remodelling and neurogenic tissue regeneration after stroke.

Slovak contribution to ESA-JUICE mission: Development of Anti-Coincidence Module ACM for Particle Environment Package PEP
Slovenský príspevok k misii ESA-JUICE: Vývoj anti-koincidenčného modulu ACM pre časticový komplex PEP
Program: Other
Project leader: Ing. Baláž Ján PhD., akademik IAA
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 ) is under development 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).

Investigation of graphene covered superconducting nanostructures by scanning tunneling microscopy
STM štúdium grafénom pokrytých nanoštruktúr
Program: Inter-academic agreement
Project leader: Mgr. Szabó Pavol CSc.
Annotation:The proposed project represents a continuation of our previous collaboration, which we started in the framework of our common APVV SK-Hu-2013-0039 project „Elaboration and characterization of graphene layers with controlled nanoscale rippling” in 2015. In this project, we have studied the physical properties of tin/graphene hybrid nanostructures applying low temperature STM microscopy and spectroscopy. We have shown, that the graphene cover layer acts as a passivating layer and protects the tin nanoparticles from oxidation. Our low temperature STM results prove that superconductivity is induced in grapheme both, when directly directly supported by tin nanoparticles or suspended among them. These results have been published in our common paper in a prestigious journal Carbon [A. Pálinkás, et al., Carbon 124 (2017) 611-617].
