It is shown that the bulk modulus of the alkali halides with rocksalt structure follows the simple relation B = b0(1 — b1fc) V where V0 is the unit cell volume, fc the spectroscopically defined covalency of the chemical bond, and b0, b1, and n are constants having the same values ...
The rocksalt phase persisted to the highest pressure studied, yielding a bulk modulus of 295(17) GPa for A1N, 323(27) GPa for GaN and 170(16) GPa for InN. The bulk moduli derived are discussed in terms of bond length and unit cell volume....

structure. Therefore, our results firmly show that the observed phase of PtC under high-pressure is rocksalt, although it is difficult to distinguish the structures of RS from ZB only by X-ray diffraction measurement[27]. We have also found[26] that the total energy of the ZB ...
Like most coiled-coils it is held together principally by hydrophobic interactions, although these are usually reinforced by salt-bridges at the edge of the hydrophobic interface, and in ROCKII there is only a single ionic interaction between the chains. The coiled-coil is packed tightly at the ...
