Functional composites based on elastomer matrix and inorganic filler
Funkčné kompozity na báze elastomérnej matrice a anorganických plnív
Program: Inter-academic agreement
Project leader: Ing. Bureš Radovan CSc.
Annotation:Advanced functional materials combining required mechanical and electro-magnetic properties currently represent a promising approach in development of new types of sensors. The primary aim of the proposed joint project is formulation of novel functional composites based on elastomer matrix modified by nano-particle fillers. To obtain materials with a broad range of physicochemical properties the polymer matrix, for instance polyurethane based on polybutadiene blocks, will be modified by different types and amounts of metallic nano-particles. Indispensable part of the proposed project is detailed structural and physicochemical characterization of the prepared composite systems. For such task specific correlations between mechanical and electrical properties and the chemical composition of the prepared systems will be primarily studied. Molecular structure will be probed by FTIR and ssNMR techniques while surface morphology will be determined using advanced microscopy. Successful solution of the proposed project requires extensive knowledge transfer between both working groups.

Solutions for Critical Raw Materials Under Extreme Conditions
Kritické suroviny pri extrémnych podmienkach
Program: COST
Project leader: RNDr. Hvizdoš Pavol CSc.
Annotation:CRM-EXTREME focuses in particular on the replacement of CRMs in high value alloys and metal-matrix composites used under extreme conditions of temperature, loading, friction, wear and, corrosion, in Energy, Transportation and Machinery manufacturing industries. The project lasts 4 years and with the goal to set up a network of expertise to define the state of knowledge and gaps in multi-scale modelling, synthesis, characterization, engineering design and recycling, that could find viable alternatives to CRMs and promote the industrial exploitation of substituted materials.

Modeling of phase diagrams of systems with boron
Modelovanie fázových diagramov systémov s bórom
Program: Inter-academic agreement
Project leader: RNDr. Homolová Viera PhD.
Annotation:The project deals with modelling of phase diagrams of systems containing boron by CALPHAD method. Main aim of the project is the development of reliable database for thermodynamic calculations of phase diagrams of studied systems. The ternary subsystems of Fe-B-Cr-V-C-Mn system are the main subject of the investigation. Known unary and binary data from literature together with results of our experimental program, based on long term annealing at high temperatures and consequent study of samples by electron microscopy, X-ray diffraction (XRD), X-ray analysis (EDX, WDX, EBSD), DTA-DSC, and also available experimental data from the literature will be used for modelling of the systems. Developed database will allow predict phase equilibria in more complex systems and can be used for modelling of diffusion processes. The results of the project will contribute to the knowledge about phase chemical composition, structure and morphology in thermodynamic equilibrium in the mentioned systems.

Advanced fibre laser and coherent source as tools for society manufacturing and life science - The surface microstructure modification of steels via the fiber laser
Pokročilý vláknový laser a koherentný zdroj ako nástroje pre spoločnosť, priemyselnú výrobu a vedu o živote - Modifikácia povrchovej mikroštruktúry ocele prostredníctvom vláknového lasera
Program: COST
Project leader: Mgr. Petryshynets Ivan PhD.
Annotation:Among the different types of Lasers, fibre lasers are, both as research and commercially, the youngest, yet the fast growing type of laser due to several factors. This Action will be the first arena where experts in fundamental material science, established laser and component groups, fibre laser manufacturers and end-users will be able to actively interact, share know-how and focus on common goals. We do expect to boost a series of innovations in the field. Among them we aim to cover the 3-6 micron wavelength interval, and beyond, to support mid-infrared applications and to enhance fibre performance to cover more efficiently visible and ultra-violet wavelength generation for biophotonics and healthcare. The Action will also investigate glass material and fibre design to overcome the actual limitation in output power. The improvements will mainly boost healthcare to benefit wide society and EU manufacturing to retain and increase manufacturing workforce within EU. The Action will mentor a new generation of researchers by providing Early Stage Researchers an opportunity to develop both scientific and management skills. At the same time the Action will actively promote gender balance and women researchers to management positions.

Project leader: RNDr. Strečková Magdaléna PhD.
Annotation:The project will be focused on preparation of soft magnetic alloys materials high energy milling of Fe and Ni with addition of glassy phase stabilizer and with addition of elements supporting nanocrystallization process. Main goal of the project is preparation and haracterization of nanocrystalline or partially amorphous alloys. Task of Czech research team will be echanochemical preparation of powder nano-crystalline material. XRD and SEM-EBSD methods will be used for characterization and optimization of mechanical milling process. Technology parameters and conditions of preparation of studied nano-crystalline alloys will be defined. Task of Slovak research team is analyses of powder morphology and particle size distribution of prepared powder alloys. Analysis of compressibility, shaping and compaction of selected powders to sample body for electric, magnetic and mechanical tests. Correlation analyse of measured characteristics will be used to obtain the information, which will be important for potential application of studied alloys in technical practice.
