Project leader: RNDr. Kovaľ Vladimír PhD.
Annotation:The main goal of the proposed project is to establish and develop a scientific cooperation between Slovakia and China in the field of multifunctional materials for advanced applications in microelectronics and spintronics. Joining of the research teams from both countries is motivated not only because of great technological potential of multifunctional materials but also due to the fascinating physics behind their unique properties. Multiferroics, exhibiting simultaneously ferroelectric and magnetic properties, are among the most attractive multifunctional materials. They allow for controlling the magnetic state of multifunctional devices with an external electric field, and vice versa. The main obstacle is, however, the scarcity of multifunctional magnetoelectrics in nature. Currently, single-phase multiferroics are far beyond any practical application, because they only demonstrate useful properties at very low temperatures. Recently, we showed that Aurivillius-type ferroelectrics doped by magnetic atoms can exhibit multiferroic behavior at room temperature. The origin of magnetism and magnetoelectric coupling in these materials, however, still needs a proper interpretation and confirmation from detailed experimental and theoretical studies. Our aim is to combine research on multiferroic materials in Slovakia with activities in China on theoretical modelling of multiferroics to design and prepare single-phase materials with the improved magnetoelectric property at room temperature.

Project leader: RNDr. Hvizdoš Pavol CSc.
Annotation:Extension of lifetime and enhancing the thermal stability of steel used for construction of exhaust pipes, heat exchangers in waste incinerators, and casting and melting aggregates in steel and glass production can be achieved via suitable anti-corrosion coatings. The aim of this project is development of new types of composite anti-corrosion protective layers, based on ceramics prepared by controlled pyrolysis of organosilicon precursors. The use of organosilicon precursors facilitates application of conventional coating technologies, such as spray and dip-coating, with subsequent pyrolysis and conversion of the precursor to amorphous ceramics. Increased thermal stability, corrosion resistance, and minimisation of volume changes related to conversion of the organic precursor to ceramics will be achieved through the addition of suitable active and passive oxide glass fillers prepared by flame synthesis in the form of microspheres.The flame synthesis facilitates the preparation of glasses with high melting point, which ensures increase of the maximum operation temperature of the coating up to 1400 oC, as well as increased oxidation and corrosion resistance of prepared coatings, optimum compatibility of the filler with ceramic matrix and metallic substrate and, due to spherical shape of glass microparticles, also negligible influence on the rheology of the system polymer-filler in the course of coating on metallic substrate.
