The quest to create superhard materials rarely strays from the use of high-pressure synthetic
methods, which typically require gigapascals of applied pressure. We report that rhenium …

Dense transition metal borides have recently been identified as superhard materials that
offer the possibility of ambient pressure synthesis compared to the conventional high …

First-principles method based on the electronic structure theory is one of the most promising
approaches of computational materials design. Although only a few of mechanical …

This article summarizes the developments of experimental techniques for high pressure x-
ray diffraction (XRD) in diamond anvil cells (DACs) using synchrotron radiation. Basic …

A concise description of models and quantitative parameters in structural chemistry and their
interrelations, with 280 tables and> 3000 references giving the most up-to-date experimental …

Hafnium carbide (HfC) is a potential candidate of ultrahigh-temperature ceramics (UHTCs)
and has attracted significantly widespread interest in recent years. Here, we have …
