A microscopic empirical model of bulk modulus based on atomic-scale parameters is proposed. These parameters include the bond length, the effective bonded valence electron (EBVE) number, and the ...

Gas hydrates are crystalline inclusion compounds formed by trapping gas molecules inside water cages at high pressures and low temperatures. Hydrates are promising materials for hydrogen storage, but ...

In a surprising overturn, the lustrous, blue-white element osmium has beaten diamond in a test of compressibility. Not used much today, osmium has been incorporated into alloys for fountain-pen tips ...
