Advanced ceramics materials Biomaterials Novel composite biomaterials that can induce the growth of connective tissue on the surface of implants and thus accelerate healing and improve the strength and biological stability of the implant-tissue connection (ceramic materials for replacement of soft and hard tissues, materials for orthopaedic devices). Materials for energetics and ecology Novel composite materials with functionally graded structures for improving the efficiency and lifetimes of components and devices for energetics (conductive ceramic materials for electrodes, catalysts for the decomposition of gaseous pollutants). Structural materials Novel ceramics and ceramic composites with excellent mechanical and thermal properties for structural applications (transparent ceramic materials, thermally and chemically resistant ceramic composite materials, impact-resistant ceramic composites).
