The Chemistry of Transition Metal Carbides and Nitrides ISBN: 9789401071994
This paper reviews the formation of several transition metal based double nitrides. The metallic nature of the nitrides has been used as the basis for understanding their properties and structure. At 3 GPa and 1673 K normally covalent GaN with a wurt

The hydrocracking of coal extracts was performed using as catalysts (in the same weight as the extract used) three kinds of molten salts, ZnCl2, ZnCl2-CuCl (3:2mol), and ZnCl2-KCl (3:2mol) at 350°C under the initial hydrogen pressure of 100kg/cm2 fo

In the depolymerization of Yubari coal in the presence of tetralin, reaction time did not alter the average molecular weight of the coal extract but it effected deoxygenation and hydrogenation in which its nitrogen content remained constant. These ef
