H2020-WIDESPREAD-2014-1 (2015-2016): SlovakION - Slovak Centre of Excellence in Ion Beam and Plasma Technologies for Materials Engineering and Nanotechnology 

The Center of Excellence SlovakION aims to become Eastern Europe’s leading research centre for ion beam and plasma technologies in materials engineering and nanotechnology. Based on cutting-edge research and closely integrated in an international network of research facilities, SlovakION’s holistic approach to innovation transfer and its close interaction with the regional industry will contribute to the economic development of Slovakia. The main focus lies with the automotive and electronics industry as pointed out in Slovakia’s Research and Innovation Strategy for Smart Specialisation. The TEAMING project shall help to develop the new Centre of Excellence as an internationally acclaimed source of excellent research. In close cooperation with the Slovak government and relevant industrial partners, SlovakION will establish and develop an integrated system for technology transfer and applied research. As a long term vision, this Slovak transfer model should be extended on other areas of research and industrial fields. The SlovakION project draws its strength from three major sources: (i) STU is Slovakia’s leading technical university with a long tradition of excellent research and education, (ii) As of today, already €42M has been committed for creating a state-of the- art facility for ion and plasma technologies. These funds were provided by the European Structural Investment Fund (ESIF), the Slovak Republic Government and the STU, and (iii) HZDR Dresden will be the leading support for SlovakION building on more than a decade of close collaboration. HZDR will not only bring its own experiences in breeding excellent research and develop fruitful technology transfer, but could draw on the whole Dresden research cluster including a leading technical university, several thematically linked Fraunhofer sites as well as several public-private partnerships fostering technology transfer.

Schéma Návraty (01.04.2018 - 01.04.2019): Predictive modelling of new finctional materials for technological applications

The project focuses on search for novel materials for innovative technologies by means of atomic-scale computational modelling. We will gain new insights into fictionalization of transition metals in form of new inorganic compounds and their attractive solid-state phases. The computational approach will be based on learning algorithms combined with quantum-mechanical Density Functional Theory methods. The project will be realized in two stages. In the first stage, new systems with transition metals will be mapped and their crystal structures characterized. In the second stage, we will shift our attention to physico-chemical properties with the aim to functionalize the new systems for applications in electronics and spintronics.

 

VEGA- 1/0418/18 (2018-2020): Time of Flight (ToF) system for Elastic Recoil Detection Analysis (ERDA) based on digital nuclear electronics

APVV-15-0105 (2016-2020): Noncovalent interactions in systems of increasing complexity

A common idea of this project is providing benchmark wavefunction data (mostly CCSD(T)) that would support DFT predictions of energetics and properties of gradually complex systems. Noncovalent interactions will be analysed, contributions many-body terms to the non additivity will be evaluated. As a prototype, beryllium clusters will be studied, binding energies per atom of Be_n up to the solid state will be of interest. The focus will be on interactions of biologically relevant amino acid clusters extracted from protein structures in the Protein Data Bank, their geometry and stability. Another class of molecules considered are metal-ligand complexes, including heavy metals. The main goal is to understand the bonding mechanism in context of their size, from small complexes to nanoclusters. Relativistic effects provide one of instruments for this analysis as well as for the analysis of iodine containing species relevant to coolant system of the nuclear reactor and in 12 complexes with antithyroid drugs. Many-body dispersion interactions will be treated using DFT in connection with layered materials and molecular crystals, their structure, elastic and thermal properties and adsorption. The alteration of properties of solute molecules in solvents, is another consequence of intermolecular interactions. This will be considered in relativistic calculations of NMR shielding constants. We combine wavefunction and DFT methods having in mind controlled accuracy. Large systems are treated using DFT, but selection of functionals is supported by extensive benchmarks on model systems. This will be achieved by further extension of efficiency of the wavefunction methods towards treating model systems closer to large molecules of interest. Important part of the project is the development of relativistic methods as well as improvement of methods for dispersion treatment within DFT. All methodological achievements will be implemented in computer programs MOLCAS, DIRAC and VASP.

VEGA- 1/0219/16 (2016-2018): High energy heavy ion-beam annealing of ion implantation synthesized silicon carbide

SiC is a promising material for a wide range of applications from semiconductor industry to e.g. in fuel elements of next generation nuclear power plants' reactors. The most recent method for SiC synthesis is based on carbon implantation into silicon substrate followed by High Energy Heavy-Ion-Beam Annealing (HE HIBA) is currently under development. Advantages of HE HIBA annealing are significantly lower temperature requirements, possibility of localized synthesis and short time of treatment, among other things. Synthesized silicon carbide will be analyzed and characterized by Rutherford backscattering spectrometry (RBS), Resonant Nuclear Reaction Analysis (R-NRA), X-ray diffraction (XRD) and transmission electron microscopy (TEM). Particularly the new experimental facility at MTF STU Trnava equipped with a 500 kV ion implanter and 6 MV tandem accelerator will be utilized. Relation between the main parameters of synthesis processes and of the resulting SiC layers will be studied.

 

VEGA-1/0335/16 (2016-2018): Searching for physical sources of the fast stochastic oscillations in accreating systems

The goal of the project is the study of the fast stochastic oscillations generated by turbulent accretion in cosmic objects, where the main driving mechanism is the accretion through a disc. This stochastic flickering usually does not originate only from a single source, hence the light curve is a superposition of more signals. Individual components can be identified by detailed study of the periodogram. For analysis of such complicated periodograms data with high cadence on long time-base are required. Ideal instrument satisfying such demands is the Kepler spacecraft. Its one-minute cadence on time-base over hundreds of days is a unique opportunity for our study. Together with our flickering simulating model based on turbulent accretion process we want to identify individual parts of the complicated periodograms calculated from Kepler telescope data, to localize their source and bring a complex model of accretion in some types of cosmic objects.

 

VEGA-1/0770/13 (2013-2015): Structure, propeties and processes at surfaces and interfaces of materials: computational modeling.

Joining is an important technological process. Frequently, there is defined an upper limit for the joining temperature due to, e.g. undesirable phase transition in the joined materials and the technological need for decreasing of the joining temperature arises. This goal can be achieved by the melting point depression – its reduction in nanostructured material in comparison to the bulk material. Nano-multilayer foils of brazing filler alloy and diffusion barrier layer (DBL) was shown to be working concept in joining. In the proposed project we address by atomic scale modeling methods structural and thermodynamical properties of the nano-multilayer systems potentially applicable in joining technology. We will apply DFT methods to model structure of the brazing alloy and DBL material interfaces and fit effective potentials for subsequent classical molecular dynamics modeling of large scale structure of interfaces and simulation of melting point depression. Benchmark interaction energies will also be provided.

 

VEGA 1/0511/13 (2013 – 2015): Study of turbulent accretion process in accreating binary systems through flickering activit

The main purpose of the project is the study of the turbulent flow in high Reynolds number (Re) regime, not accessible in today’s laboratories. Accretion systems are unique cosmic experiments to do so. The turbulence minimum dimension scales in the fluid are described by the Re. The largest scales of fluid motion are set by the overall geometry of the flow and are dissipating into smaller eddies up to the minimal dimension scale. From the basic fluid mechanics it is well known that higher Re numbers yield smaller minimal dimension scale. From Re about 10^6 the dissipation toward smaller scales of turbulent elements is so strong that the fluid becomes quasilaminar. The bigger eddies should dissipate and hence disappear. Today Re estimates from Earth goes toward a value of about 10^8. What is happening then? The typical Re in an accretion disk of cataclysmic variables is of about 10^12 and one of the possibility to explain flickering are turbulence in the disc. Can the flow tell something about the size of the turbulence? Why do we observe the flickering if the turbulence should "disappear" for Re ~ 10^6?
