Currently I am finishing the 2nd volume of my book on UHTM devoted to refractory carbides (TaCx, HfCx, NbCx, ZrCx, TiCx and VCx), so I would like to include in it all the newest data on structural, thermal, electro-magnetic, optical, physico-mechanical and physico-chemical properties of these compounds, which sometimes are given in the publications (journals, chapters, books) not referred to in Scopus and Web of Science.
