Annotation:The reconstruction of Nuclotron-NICA accelerator system and building of the multi-purpose detector system (MPD) is currently underway in the V. I. Veksler and A. M. Baldin Laboratory of High Energy Physics (VBLHEP) in the Joint Institute for Nuclear Research in Dubna (Russian Federation). The main goal is to enable further experimental research in the field of relativistic nuclear physics of heavy and light ions. It is therefore necessary to upgrade the equipment in the area of internal targets station of Nuclotron. This innovation assumes a partial, respectively complete substitution of equipment and materials in the vacuum chamber of internal targets station of Nuclotron. In the context of cooperation between VBLHEP and Institute of Physics it is planned to innovate the electronic apparatus intended for the above described experiments. The experiments require electronics to work in a high vacuum. This requires an innovation of electronic blocks of the internal targets station, upgrading of targets position measurement system in the vacuum chamber, implementation of stabilization of the motion of targets in high vacuum conditions. It is necessary to upgrade the control system, upgrade the connection to the control electronics of the targets chamber and rebuild the software equipment completely.

MultiComp - Multi-Functional Nano-Carbon Composite Materials Network
Multifunkcionálne nanokarbónové kompozitné materiály
Program: COST
Project leader: Dr. Rer. Nat. Šiffalovič Peter PhD.
Annotation:MultiComp is a COST Action designed to bring together theorists, experimentalists and industrialists in the field of nano-carbon materials technology. Although carbon nanotubes, graphene and Few-Layer Graphene (FLG) have been used to improve the properties of composite materials, two main problems remain to be solved before these composite materials can realize their full potential: (1) adequate dispersion of the nano-carbon reinforcement material, and (2) strong enough interfacial bonding between the nano-carbon reinforcement elements and the composite matrix. In addition to making modified MWNTs such as branched-MWNTs, the Action will explore other possibilities of strengthening composites by integrating FLG (using existing as well as unpublished methods); theoretical modelling of these nano-carbons and composites; due consideration and evaluation of the Health, Safety and Environmental implications; making and testing composites e.g. mechanical and electrical/thermal, HRTEM of interphases, voltage-contrast SEM of percolation networks, sensing and photocatalytic properties; development of new composite materials with Electronic and Multi-Functional properties. This Action will provide an ideal platform, especially via STSM exchanges, for permanent established researchers, post-doctoral workers and ECIs to enhance their research-related skills as well as their innovation and enterprise skills in this international network involving both academic and business enterprises.

AFM-IMASS - AFM: Imaging, manipulation, atomic-scale simulation
AFM: Zobrazovanie, manipulácia, simulácia na atomárnej škále
Program: APVV
Project leader: prof. Ing. Štich Ivan DrSc.
Annotation:The AFM-IMASS project focuses on imaging and manipulation of surfaces and nanostructures on them using local atomic-scale SPM methods. For imaging the AFM and to a lesser extent also STM methods will be used. For atomic manipulation the AFM methods will be used and for manipulation of electronic charge the KPFM methods. All experiments will be backed up by computer simulations using mainly methods of density functional theory and, for correlated systems, by correlated electronic structure methods, QMC in particular. In order to achieve these objectives we will use the well-proven international consortium which in the last 5 years has generated several top results published in journals with highest impact factors (Nat. Phys., Nat. Commun., Nano Lett., ACS Nano, J. Am. Chem. Soc.). In addition to the Inst. of Physics SAS (group of Prof. Stich, computer modeling and simulation), this consortium consists of Dept. of Appl. Physics, Osaka University (prof. Sugawara and prof. Li, sample preparation and non-contact AFM/KPFM experiments), Dept. Appl. Phys. University Giessen (Prof. Schirmeisen, nanotribology experiments), and King's college London (prof. Kantorovich, theory and simulation). For the purpose of the AFM-IMASS project this consortium will be extended by Inst. of Physics CAS (Prof. Jelinek, AFM/KPFM of correlated systems). In line with that we envisage three principal research directions: 1) Transition metal oxide surfaces with focus on their catalytic properties, 2) Organometallic materials and polymers and their electronic properties: 1D and 2D ferrocene, and 3) Nanotribology with focus on structural superlubricity. Scientific objectives will be complemented by 4) Educational and public outreach targeting young generation. Objective of the current AFM-IMASS project will be top internationally competitive results with the ambition of publishing them in the journals with highest impact factors- part of the results in journals with impact factors >10.

MICROPAN - Rational design of hydrogel microcapsules for immunoprotection of transplanted pancreatic islets in diabetes treatment
Cielený dizajn hydrogélových mikrokapsúl pre imunitnú ochranu pankreatických ostrovčekov v liečbe cukrovky
Program: APVV
Project leader: Dr. Rer. Nat. Šiffalovič Peter PhD.
Annotation:This project is devoted to our continuous effort aimed at the diabetes treatment by transplanted insulin-producing cells that are immunoprotected from the host immune system by a semipermeable polymer membrane. This membrane is in the form of a hydrogel microcapsule formed by the polyelectrolyte complexation of polyanions, the sodium alginate (SA) and sodium cellulose sulfate (SCS) with the polycation poly(methylene-co- cyanoguanidine), (PMCG). Over the past two decades we have accumulated important knowledge showing that this type of microcapsule (acronym PMCG), belongs to the family of microcapsules with a promise to reach the phase of clinical trials. There are two principal advantages of this microcapsule: (1) it exhibits biocompatibility after intraperitoneal implantation to various animal models, including the pre-clinical model of non-human primates (NHP), (2) it affords a unique ability to tailor the physico-chemical properties in correlation with in vivo performance that is not possible for other encapsulation systems. The MICROPAN project aims at the first systematic investigation for the microencapsulation system of the correlation between polymer selection, encapsulation conditions, microcapsule properties and in vivo performance. This is thanks to the availability of in- house synthesized SCS and PMCG polymers used instead of commercial polymers with inconsistent characteristics. The expected project outcome will be the library of microcapsules of predicted performance in vivo in the immunocompetent mice with the proposal to test selected microcapsules in NHPs that will be planned outside of MICROPAN project. This project will enhance our understanding of the mechanism of microcapsule formation by polyelectrolyte complexation and, hence, will contribute to the future rational designs of microcapsules for immunoprotection of transplanted cells.

HvdWH - Real-time grow studies of hybrid van der Waals heterostructures
Časovo-rozlíšené štúdium rastu hybridných van der Waalsových heteroštruktúr
Program: APVV
Project leader: RNDr. Mrkývková Naďa PhD.
Annotation:The van der Waals heterostructures (vdWHs) are newly discovered physical structures that consist of several two-dimensional (2D) atomic layers held together by weak van der Waals forces. The vdWHs show unique functionalities that are not accessible in their three-dimensional counterparts. This project is focused on the investigation of the hybrid vdWHs (hybrid refers to the fact that at least one of the layers is organic) with large application potential in organic electronics and optoelectronics. In particular, we will investigate the growth kinetics, molecular orientation, structure and lattice parameters of organic thin films deposited on 2D substrates. The proposed research will address fundamental questions of the molecular thin film growth processes with particular emphasis on time-resolved in-situ experiments. The novelty of this project resides in the use of new and intriguing 2D materials as the substrates for the growth of organic molecular films and in a detailed investigation of this growth process in order to tailor preparation of novel hybrid vdWHs with specific properties. We will use 2D substrates with different electronic properties, namely the semimetal graphene and the semiconducting MoS2 thin films, which both have strong application potential in nowadays electronics. Regarding the organic molecules, we will concentrate on those possessing the properties beneficial for optoelectronics, such as absorption in the visible spectrum range, good electric conductivity and capability of self-assembly. We will start with pentacene and TzTz-based small molecules. We believe that such basic research is highly relevant for further development of enhanced organic electronic applications such as organic light emitting diodes, organic field effect transistors and organic solar cells.

Monocell - In situ growth process and controllable preparation of perovskite monolayer films
In situ monitorovanie rastu a riadená príprava monovrstiev perovskitov
Program: APVV
Project leader: Dr. Rer. Nat. Šiffalovič Peter PhD.
Annotation:Metal halide perovskites are an exciting class of materials that possess many of the attributes desirable for optoelectronic applications, with certified power-conversion efficiencies of perovskite-based photovoltaics reaching 23%. Photoluminescence quantum efficiency of thin films used in highly efficient devices is still low (~1%), which is mainly consistent with sizable density of sub-gap trap states that act as non-radiative recombination centers. In order for a solar cell to reach its theoretical performance limits, luminescence should be maximized with all non-radiative recombination eliminated. The conventional perovskite films prepared by solution process are usually composed of nanoscale grains so that there are a number of boundaries in the film. Correspondingly, a perovskite monolayer with single crystal cross-section profile is considered to be the desired active layer. The characteristics of the monolayer film are very close to that of the single crystal film. However, how to prepare a monolayer perovskites film with single crystal cross-section profile for solar cells is still a big challenge. The primary project’s objective is to identify the key mechanisms governing the formation of perovskite thin films during solution fabrication process. Accordingly, systematic understanding of perovskite crystals growth process is highly required and will be sorted out by real-time and in-situ GI-WAXS/SAXS complemented by real-time photoluminescence. The ex-situ energy-resolved electrochemical impedance spectroscopy of trap states in bandgap will be employed to elucidate the relationship between the electronic and structural properties of perovskite thin films. The principal aims of this joint research proposal are focused on understanding of growth mechanism of the perovskites, which will enable controllable fabrication of perovskite monolayer films for high efficiency solar cells.

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.

The effort of researchers included in this project is focused on optimisation of theoretical proposals, also by taking into account more realistic models reflecting the situations outside the laboratories. Our project joins the second quantum revolution on the side of theory, while aiming at mid-term quantum technology applications.

In particular, we aim to investigate the mathematical structure of quantum information resources in order to utilize them in novel and efficient quantum metrology applications and quantum simulations. The planned analysis of higher-order quantum structures and related optimal information processing is uncovering new quantum resouces (e.g. quantum causality, memory) that has potential to boost qualitatively the performance of quantum computation and communication technologies. Our plans to optimize tensor network algorithms by using the structure of interactions (space-time) are definitely enlarging our chances for efficient quantum simulations of physically relevant quantum many-body systems. Project tasks are divided into three workpackages aiming to optimize quantum structures, develop optimal higher-order quantum information processing and optimisation of tensor network algorithms.

BENECON - 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.

DiaGraph - Properties of the graphene-diamond interface: study on the atomic level
Vlastnosti rozhrania grafén-diamant: štúdium na atomárnej úrovni
Program: APVV
Project leader: Dr. Rer. Nat. Šiffalovič Peter PhD.
Annotation:The performance of electronic devices made of graphene substantially depends on the interactions of graphene with a substrate beneath, mostly silicon substrate covered with oxide layer. The reasons are numerous: remote phonon scattering, charge traps, adsorbed dopants, etc. Recently it was proven that changing silicon to diamond substrate significantly improved performance of the graphene devices. However, theoretical calculations of interactions at the graphene – diamond (GOD) interface vary and often contradict each other. Systematic experimental studies related to the nature of GOD interactions are missing. In our project we propose experimentally to realize systems of graphene-on-diamond by different routes that will result in different GOD interfaces. We will investigate the atomic and electronic structures using HRTEM/STEM with atomic resolution, and perform other complementary characterizations. We will also produce GOD field effect devices and will relate the transport properties to the resolved structure at the GOD interface. The final goal is to understand the interactions between graphene and diamond and their relation to electronic transport.

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.

Ground state and low-temperature properties of classical Coulomb systems
Základný stav a nízkoteplotné vlastnosti klasických coulombovských systémov
Program: VEGA
Project leader: RNDr. Šamaj Ladislav DrSc.
Annotation:The project concerns the theoretical investigation of the ground state and low-temperature thermodynamics for systems of classical particles with Coulomb interaction. We shall study the phase transitions, critical exponents and the tricritical behavior of Wigner mono- and bi-layers which minimize the energy for the case of dimers of equivalent charges and dipoles of opposite charges. We shall derive the effective interaction between two equivalent macromolecules immersed in water. We shall study the effect of their charged surfaces on the space distribution of released micro-ions to describe a paradoxical attraction of the same charges based on the WIgner picture. We shall establish a theory to describe the low-temperature thermodynamics of micro-ions with a finite hard core. We shall try to construct a universal theory which interpolates correctly between the high-temperature Poisson-Boltzmann approach and the low-temperature Wigner description, respecting at the same time the contact theorem.
