Ab initio calculations of temperature dependent resistivity for transition metals
Wagenknecht, D. ; Turek, Ilja ; Carva, K.
The effect of phonons on electrical resistivity has been simulated by considering random displacements of atomic nuclei from their equilibrium positions together with a frozen-potential approach. The developed theory has been applied successfully to late transition metals (Fe, Ni, Rh, Pd, Pt).
Plasmachemical synthesis of borides, carbides and nitrides of transition metals
Brožek, Vlastimil ; Ctibor, Pavel
For technical practice the most important are up to now borides of titanium and zirconium, carbides of boron, calcium, silicium, titanium, zirconium, hafnium, aluminum and chromium. Nitrides of boron, silicium and titanium. Besides of tungssten carbide, any of the mentioned compounds is proced presently in the Czech Republic, however the know-how and suitable conditions are existing. The contribution describes possibilities of the processing of the mentioned materials to functional layers or thin-walled shaped parts by plasmachemical methods.
Vliv nosičů gamma-Al2O3, TiO2 a ZrO2 na hydrodesulfurizační aktivitu sulfidů přechodových kovů
Kaluža, Luděk ; Zdražil, Miroslav
A significant effect of ZrO2 and TiO2 supports on the hydrodesulfurization-activity ranking of V, Cr, Mn, Fe, Co, Ni, Mo, Ru, Rh, Pd, W, Re, Os, Ir and Pt sulfides studied was ascertained.
