At the beginning of 90th Andrey Ragulya proposed the theoretical basis for Rate Controlled Sintering Process (RCSP), which previously had been experimentally considered by Prof. H.Palmour III. For the first time RCSP has been applied in the area of nanograined materials. Andrey Ragulya put forward a new ideology of so-called rate-controlled thermally activated processes, which has been confirmed experimentally for numerous technological processes, in particular, synthesis of nanosized particles of ceramic and metallic materials. His recent research activity focuses on the obtaining and characterization of nanosized particles, nanostructured ceramics & ceramic nanocomposites. In 2015 he was awarded with the State Prize of Ukraine for these efforts. Since 2002 he has been in the position of Deputyirector at IPMS and the research team leader in the development of nanomaterials at IPMS. He is an author of 6 books and 1 textbook in the area of nanomaterials, more than 270 papers and 16 patents.
