High pressure structural studies on Nb5Si3 up to 26.2 GPa

Superconducting phase diagram of Li metal in nearly hydrostatic pressures up to 67 GPa.

The dependence of the superconducting transition temperature T(c) on nearly hydrostatic pressure has been determined to 67 GPa in an ac susceptibility measurement for a Li sample embedded in helium pressure medium. With increasing pressure, superconductivity appears at 5.47 K for 20.3 GPa, T(c) rising rapidly to approximately 14 K at 30 GPa. The T(c)(P) dependence to 67 GPa differs significantl...

Conformation of p-terphenyl under hydrostatic pressure.

The conformation of p-terphenyl (C18H14) and deuterated p-terphenyl (C18D14) has been investigated, using high-pressure infrared spectroscopy at liquid-helium temperatures. First-principles calculations, together with the experimental results, were performed to determine the structure of p-terphenyl in the twisted conformation. At low temperatures and pressures, p-terphenyl belongs to the C2 po...

Infrared spectroscopy of biphenyl under hydrostatic pressure

Changes in the conformations of conjugated molecules affect the optical and electronic properties significantly. Hydrostatic pressure has been used to probe the conformations of biphenyl (C12H10) and deuterated biphenyl (C12D10) at liquid-helium temperatures. Infrared ~IR! spectra of these materials have been taken up to a pressure of 2 GPa. A disappearance of certain IR absorption peaks has be...
