X-ray Raman Scattering of Water Near the Critical Point: Comparison of an Isotherm and Isochore
D. Ishikawa, Y. Q. Cai, D. M. Shaw +3
X-ray Raman spectra of liquid, sub- and super- critical water at the oxygen K-edge were measured, at densities 1.02 - 0.16 gcm^-3. Measurements were made along both an isotherm and…
Bonding, structures, and band gap closure of hydrogen at high pressures
Alexander F. Goncharov, John S. Tse, Hui Wang +4
We have studied dense hydrogen and deuterium experimentally up to 320 GPa and using ab initio molecular dynamic (MD) simulations up to 370 GPa between 250 and 300 K. Raman and opti…
Superconductive "sodalite"-like clathrate calcium hydride at high pressures
Hui Wang, John S. Tse, Kaori Tanaka +2
Hydrogen-rich compounds hold promise as high-temperature superconductors under high pressures. Recent theoretical hydride structures on achieving high-pressure superconductivity ar…
