International audience; Material equation-of-state (EOS) models, generally providing the pressure and internal energy for a given density and temperature, are required to close the equations of hydrodynamics. As a result they are an essential piece o

Publikováno v: Physical Review B. 95

Density functional theory calculations using the quasiharmonic approximation have been used to calculate the solid Hugoniot of two polytypes of boron carbide up to 100 GPa. Under the assumption that segregation into the elemental phases occurs around

Superconductivity in Hydrides Doped with Main Group Elements Under Pressure

Autor: Eva Zurek, Andrew Shamp

Publikováno v: Novel Superconducting Materials. 3

A priori crystal structure prediction techniques have been used to explore the phase diagrams of hydrides of main group elements under pressure. A number of novel phases with the chemical formulas MHn, n > 1 and M = Li, Na, K, Rb, Cs; MHn, n > 2 and

Publikováno v: Physical Review B. 94

A equation of state (EOS) experimental technique that enables the study of thermodynamic derivatives into the TPa regime is described and applied to boron carbide (${\mathrm{B}}_{4}\mathrm{C}$). Data presented here are principal Hugoniot sound speed

Compressed Cesium Polyhydrides: Cs+ Sublattices and H3– Three-Connected Nets

Autor: Eva Zurek, James Hooper, Andrew Shamp

Publikováno v: Inorganic Chemistry. 51:9333-9342

The cesium polyhydrides (CsH(n), n1) are predicted to become stable, with respect to decomposition into CsH and H2, at pressures as low as 2 GPa. The CsH3 stoichiometry is found to have the lowest enthalpy of formation from CsH and H2 between 30 and
