The modern synthesis of superhard and, especially, ultrahard phases is a fascinating area of
research that could lead to the design of new, industrially important materials …

Since the discovery of spinel nitrides in 1999, there has been a lot of effort in basic science
to further develop advanced nitrides and electronic nitrides. The aim and scope of the …

We report here the high-pressure synthesis of well-sintered millimeter-sized bulks of
superhard BC2N and BC4N materials in the form of a nanocrystalline composite with …

Heterodiamond BC 2 N, as a kind of superhard material expectable, is studied using the ab
initio pseudopotential density functional method. All the calculations are performed after …
