Magnetic behavior and domain structure of modern soft-magnetic materials
Magnetické správanie a doménová štruktúra moderných magneticky mäkkých materiálov
Program: Medziakademická dohoda (MAD)
Project leader: RNDr. Butvinová Beata CSc.
Annotation:Soft-magnetic ribbons produced by rapid quenching of the melt and subsequent thermal treatment are already used in the industrial practice and still offer possibilities of smart compositions recently aimed namely to higher magnetic saturation induction. Magnetic properties of some special compositions greatly profit from partial nanocrystallization after thermal treatment that leads to formation of fine sized grains. Actual knowledge of surface effects on magnetic properties of the positively magnetostrictive Fe-based ribbons showed that in-plane surface compressive stress comes from surface crystallization and oxidation during non-vacuum annealing. The main aim of this proposal is to investigate correlations between mechanical and magnetic properties to better clarify the surface layer influence.

Program: APVV
Project leader: prof. Ing. Štich Ivan DrSc.
Annotation:2D - MAT&FUN project is conceived as an international project on graphene and graphene - like 2D materials and their functionalization aiming at tailoring their electronic, magnetic, spintronics, and sensorics properties. The quest is to harness the synergy between theory and experiment groups and between theo ry and theory groups represented by three top - end - of the line theory (CCMS at Institute of Physics SAS (CCMS), University of Regensburg (UREG), and North Carolina State University (NCSU)) and two experimental groups (Osaka University (OUNI) and Justus Lieb ig University Giessen (JLUG)). Primary role of the proposer, CCMS, will be studies using ultra - accurate computational studies based on explicitly correlated many - body techniques, such as quantum Monte Carlo (QMC). Our preliminary results clearly indicate t hat use of these accurate techniques is imperative for reliable description of functionalization of these materials with d - electrons, for accurate description of electronic properties, or for description of energetics of catalytic or sensoric properties of these novel materials. The QMC studies will be supported by the experts at the NCSU. The results of our correlated modeling will serve as inputs into more coarse - grained spintronics modeling at the spintronics group at UREG. Our computer modeling will als o serve as back - up support for the primarily SPM experiments at the OUNI and JLUG on this group of materials. As a basic research project the main outcomes are expected in the form of outstanding results publishable in highest - impact journals, numerous cit ations and invited talks at international conferences. These research results will be accompanied by public outreach activities in daily press and by events targeting primarily, but not exclusively, the high school students via strong presence at Tournamen t of young physicists, Olympiad of young scientists, Researcher’s night, etc, where top - end of the line scientific results will be highlighted.

MAGRID - Efficent preparation of powdered magnesium hydrid directly from the magnesium melt
Ekonomická príprava práškového hydridu horčíka z roztaveného horčíka
Program: APVV
Project leader: Ing. Švec Peter DrSc.
Annotation:Magnesium hydride is one of the most promising materials for safe storage and transport of hydrogen. It is mostly produced by long term mechanical milling and is thus very expensive what greatly limits its practical application. This applied research project is therefore aimed to verify economically attractive method of magnesium hydride production via direct spraying of molten magnesium or its complex alloy with compressed hydrogen and produce th us proper structure for repeatable storage of hydrogen. The subject of the research is to study the effect of the composition of the melt, cooling rate, gas pressure and size of the powder particles onto the amount of hydrogen absorbed in the solid powder. In addition, the ability of such powder to absorb and desorb the hydrogen repeatedly without excessive creation of passive layer on the powder particle surfaces will be determined. The ways of further use of powder after exhausting its ability to effectiv ely bind hydrogen will be examined as well. The successful results of the project could revolutionary help in the storage of energy from clean and renewable sources, thus contributing to the formation of sustainably clean environment.

MoSense - Smart MoS2 platform for cancer diagnosis and targeted treatment
Inovatívna MoS2 platforma pre diagnózu a cielenú liečbu rakoviny
Program: APVV
Project leader: Dr. Rer. Nat. Šiffalovič Peter PhD.
Annotation:The goal of the proposed project is to develop a novel smart 2-dimensional multifunctional nanoplatform based on MoS2 for cancer cell detection and treatment. The MoS2 nanosheets prepared by liquid phase exfoliation and/or Li intercalation and modified for low toxicity and high biocompatibility will be chemically functionalized with antibodies sensitive to specific cancer cells and relevant cytotoxine. In comparison to graphene based nanosheets the MoS2 provides much stronger signal for the advanced laboratory diagnostics such as Raman spectroscopy, X-ray methods, SEM and TEM. Strong Raman signal and photoluminescence of MoS2 nanosheets will allow a label-free in situ tracking of the nanoplatform localization at the cell level. This will be one of the original project contributions to the knowledge of the cell interaction with the functional nanoplatform in general. The new quality of the laboratory testing of the nanoplatform interaction with the cancer cells may bring new knowledge and essential progress in the field of 2D nanoplatform generally. New knowledge is expected also in terms of a smart handling of biocompatibility and toxicity of the nanoplatform which is important for the nanoplatform cell internalization. Newly elaborated technological procedures will have direct implications for tailored 2D materials technology.

ProQuNet - Probing quantum networks with quantum walks
Prieskum kvantových sietí pomocou kvantových kráčaní
Program: APVV
Project leader: RNDr. Reitzner Daniel PhD.
Annotation:In the theory of quantum information and computation quantum walks play a role of a specific system that is relatively simple both from theoretical and experimental side, yet still complex enough to provide computational advantage over classical applications while being universal for computation in general. This can have significant implication to applications in implementation of quantum technologies and in the near future it can serve as a good mid-size quantum simulator. A specific task relevant to advance in quantum technologies is the topic of probing quantum networks. In this project we plan to address this task from the specific view of scatterings on graphs by attaching semi-infinite runways on chosen locations in graphs which serve as input and output leads for quantum walkers. By doing so we want to first identify features of the graphs that are recognizable by this approach, while being efficient (in the length of the wave packet). These findings will be used for particular task such as searches for defects or their avoidance, routing of walkers, scattering simulators, programmable transports or transports under decoherence. For these aims we will use know-how of both groups - the Slovak partner is an expert in quantum searches and computation complexity while the Portuguese partner is an expert in studying transport properties on graphs, spatial search by quantum walks, and how these are affected by defects.

Annotation:The project is based on a strong collaboration with foreign experimental groups (Osaka University, Giessen University, North Carolina State University, University, Regensburg) with the objective to provide theoretical modeling to those experiments. The following projects are foreseen: 1) imaging and manipulation with (non-contact) atomic force microscope (NC-AFM), 2) nanotribology, (3) spintronics and magnetic nanostructures on graphene, (4) study of molecular switches. We plan predominantly use two modeling tools, namely density functional theory methods (DFT) and correlated methods of quantum Monte Carlo (QMC). In particular in 1) we plan study of Al2O3 surface (alumina), for which we have high-quality NC-AFM images which will be used to elucidate the still not fully understood atomic structure. 2) In the field of nanotribology we plan to study the superlubric behavior of nanoparticles.

QWIN - Quantum Walks and Incompatibility
Quantum Walks and Incompatibility
Program: SASPRO
Project leader: RNDr. Reitzner Daniel PhD.
Annotation:The project consists of two separate parts, one on quantum walks (split into scatterings and decoherence questions) and the second one on quantum incompatibility. In the first year of the project we addressed the issue of the decoherence in quantum walks, i.e. how are the applications of quantum walks affected by decoherence on given network. One partial result in this direction is that decoherence in quantum searches rather quickly destroys its efficiency up to few extra cases. This is, however, done only for a specific task related to Grover quantum search. The second result is the detection of extraneous edges, which might be considered as a leakage in the network. This result is still preliminary. Objective on quantum incompatibility aimed this year at describing a general degree of incompatibility necessary for considering quantum incompatibility as a resource in quantum applications. This point has been addressed fully with additional results of providing a generalized Tsirelson bound. Further additional results, not planned within the project, but relating to the objective, were the expansion of the degree of incompatibility on measurements on evolutions and the description of dynamical effects on incompatibility.

In the related research the representative part of the Slovak scientific basis will be involved, namely the Slovak University of Technology (STU) in Bratislava, the Institute of Physics (IP) of the Slovak Academy of Sciences (SAS), and the Institute of Materials Research (IMR) of SAS. To fulfil project tasks, the top - level recently provided equipment will be use d, available at the university scientific parks of STU located in Bratislava and Trnava as well as at the scientific centres of SAS located in Bratislava (IP) and Košice (IMR).

WearQuPros - Weak Randomness in Quantum Protocols
Slabá náhodnosť v kvantových protokoloch
Program: VEGA
Project leader: Doc. RNDr. Plesch Martin PhD.
Annotation:Security is one of the most used words nowadays, whether in science, politics, economy or every-day life. Meaning of this word has, however, changed significantly throughout recent decades. To be secure means often to have more information than the enemy rather than to have a more powerful army than the enemy. It is of a vital importance for the whole community to achieve security of any information that is being communicated worldwide. The aim of this project is to question and re-establish security in a specific domain of protocols, namely protocols utilizing properties of Quantum physics. Many of these protocols are believed to be secure in most situations, hence we will concentrate on a very specific kind of attack, where an adversary can influence the sources of randomness used in protocols. Preliminary results show that this capability of an adversary can significantly reduce the security of existing protocols or their particular implementations and it is thus important to examine this problem in detail.

The behaviour of new progressive construction materials in aggresive enviroment of molten salts
Vlastnosti nových progresívnych konštrukčných materiálov v agresívnom prostredí roztavených solí
Program: APVV
Project leader: Ing. Švec Peter DrSc.
Annotation:Proposed project deals with the complex research of corrosion processes on advanced construction materials that take place in aggressive molten fluoride salts. Research objects are special alloys and ceramic materials for high temperature applications prepared by different methods and consequently thermally threated . The study of the corrosion induced microstructure degradation is a key part of the project. The main objective is to understand corrosion damage of microstructure of construction materials in molten salts using multidisciplinary combination of techniques . Based on these techniques it is possible to analyse and characterise also very gentle changes in local structure of corrosion interlayers on atomic level between molten medium and material at elevated temperatures. Complex information on physical nature of particular molten systems is in centre of interest, as well. The combination of diffraction, imaging and spectral methods in combination with theoretical calculation enable us to determine structural characteristics of new phases formed in the corrosion process. Evaluation of the processes that take place will provide permanent share in studied field. This share can be even generalised and applied in many other fields.

Intrinsic macroscopic forces - what are its sources and how it impacts magnetic properties of high-induction metallic ribbons
Vnútorné makroskopické sily - z čoho pochádzajú a ako ovplyvňujú magnetické vlastnosti vysokoindukčných kovových pások
Program: VEGA
Project leader: RNDr. Butvinová Beata CSc.
Annotation:The project is focused on specific properties of new soft-magnetic nanocrystalline materials that show a high surface to volume ratio. These modern materials target high saturation induction and are developed for power electronics, which is necessary for an efficient production of electricity from renewable sources. Economic reasons dictate to use cheap and available feedstock and high induction demands to be sparing with nonmagnetic elements. Thus certain properties regarded marginal with alike older materials now become important: Macroscopic heterogeneity resulting in mutual forces between surface and interior of the magnetic component (thin ribbon, powder) can build up and significantly affect useful magnetic properties. We already study such properties on very similar ribbons in recent years. We thus believe to effectively use the knowledge and experience to achieve the project goals aimed at explaining the properties and so enabling optimal choice of composition and treatment of the modern materials.

Annotation:The project deals with development of the surface processing technology based on single-point diamond turning and fly cutting and their implementation in preparation of elements for the next generation of multifunctional crystal X-ray optics, in particular those based on germanium, silicon and copper.The main parameters under study will be morphology of the processed surfaces on various length scales and degree of subsurface damage of the crystal lattice with the aim to minimize surface roughness and damaged region. This will guarantee supression of the diffuse X-ray scattering and geometrically and spectrally pure working X-ray diffraction that is particularly important for strongly asymmetric diffraction with added functionality of the beam shaping. In addition to the diamond processing the project will focus on final treatment of active surfaces of the crystal X-ray optics, namely by combination of mechanical and chemical methods as well as by utilization of ion beams and pulsed nanosecond laser source.

DevTransSens - Development of sensors and measurement methods for transient techniques for the measurement of thermophysical properties of materials and their application for seasonal storage of heat energy
Vývoj senzorov a metód pre prechodové metódy merania termofyzikálnych vlastností látok a ich aplikácia pre možnosti sezónneho uskladnenia tepelnej energie.
Program: VEGA
Project leader: Ing. Boháč Vlastimil CSc.
Annotation:Investigation of thermophysical properties of natural materials with new sensors and methods. Thermal properties of rocks are important at solving the problems of seasonal storage of heat energy in geological formations around the houses. To optimize the process of the energy acumulation it is necessary to know the thermo-physical properties of the surrounding material in which the energy is stored. We must know the values of coefficient of thermal diffusivity, thermal conductivity and specific heat capacity for the numerical simulation of heat transport phenomena for the transfer from the heat exchanger into the bedrock materials (eg. Limestone and clay loam). In the frame of project there will be designed and manufactured single-probe thermo-physical sensors and their modifications for in-situ measurements. The new sensors will be placed in the ground in the hole bored in different geological conditions, so clay loam and rock massif. For the new single-probe sensors there will be derived the new models.

Electronic transport vs. structure, size and ordering in nanoparticle arrays for advanced gas sensors
Vzťah elektrónového transportu a štruktúry, rozmerov a usporiadania v nanočasticových súboroch pre pokročilé senzory plynov
Program: VEGA
Project leader: Dr. Rer. Nat. Šiffalovič Peter PhD.
Annotation:The aim of the research is the new knowledge on electronic transport in arrays from semiconducting iron oxide nanoparticles (NPs) combined also with graphene oxide vs. their lateral and vertical ordering. Arrays will be prepared by modified Langmuir-Schaeffer deposition and their structure will be studied mainly by GISAXS. Electronic transport in these arrays used e.g. in NP gas sensors is not understood enough. Its complexity follows from the combination of inter- and intraparticle components depending on the size effects. Understanding of the transport together with surface molecular interactions is a key to advanced gas sensors for healthcare, protection of environment and civil security. However, the research diverges and its systemization depends also on the clarification of transport. Sensors must be also thermally stable and structurally homogeneous to facilitate further miniaturization and integration into electronic circuits.

Relations between electronic structure and microstructure of copolymer thin films
Vzťahy medzi elektrónovou štruktúrou a mikroštruktúrou tenkých kopolymérnych vrstiev
Program: VEGA
Project leader: RNDr. Gmucová Katarína CSc.
Annotation:The efficiency of sunlight conversion to electricity relies, among other things, on the charge separation after the photovoltaic process initiation by the absorption of a photon which generates an exciton. The presence of a donor-acceptor interface in the thin films confines the electron and hole in their respective layers and facilitate thus the charge separation. In past years, the synthesis of novel all-conjugated copolymers bringing together hole- and electron-conductive polymers turned up to be of utmost importance. The relations between microstructure and electrical properties of such copolymers are far from being clearly understood. This originates from the presence of both the ordered (polycrystalline) and disordered (amorphous) phases in the solution-processed thin films. This project proposal is focused on the explanation of the relations between the microstructure of copolymer thin films and the structural defect-related DOS, which markedly influences the functionality of solar cells.
