1. Synthesis and characterization of nanocarbons as reinforced particles in metal composites
Abstract : In this work, several scientific problems related to high pressure–high temperature (HP–HT) synthesis of new materials using fullerite as a precursor were studied: first, the mechanism of the transformation of C60 crystal into a nano-clustered graphene phase (NGP) at a pressure of 8 GPa; and second, the effect of disorder introduced into C60 crystals by ball milling prior to HP–HT synthesis on the structure and properties of the NGP. A separate set of experiments was devoted to compression of C60 precursor at unexplored before pressure of 25 GPa and elevated temperatures in search for new type of disordered carbon-based materials.

3. Entropy-stabilized transition metal diborides for high-temperature applications
Abstract : Ultra-high temperature ceramics (UHTCs) are on the cutting edge as structural or protective materials that can withstand extreme environments such as hypersonic vehicles, nuclear reactors, and advanced turbine engines. These materials stand out for their melting temperatures above 2500 °C, high chemical stability, and retained mechanical resistance at temperatures higher than 1650 °C. READ MORE
