The high-pressure-high-temperature behavior of bassanite

American Mineralogist, 2009
The pressure evolution of bassanite (CaSO{sub 4} {center_dot} 1/2 H{sub 2}O) was investigated by synchrotron X-ray powder diffraction along three isotherms: at room temperature up to 33 GPa, at 109 C up to 22 GPa, and at 200 C up to 12 GPa. The room-temperature cell-volume data, from 0.001 to 33 GPa, were fitted to a third-order Birch-Murnaghan ...

NANOMATERIALS UNDER HIGH TEMPERATURE AND HIGH PRESSURE

Modern Physics Letters B, 2010
Two different approaches to study thermal expansion and compression of nanosystems are unified, which have been treated quite independently by earlier workers. We provide the simple theoretical analysis, which demonstrates that these two approaches may be unified into a single theory, viz. one can be derived from other.

On the structure of high-pressure high-temperature η-O2

The Journal of Chemical Physics, 2009
In situ high-pressure high-temperature x-ray diffraction and optical studies have been conducted on solid oxygen between 10 and 20 GPa and up to 700 K. Optical observations and Raman spectroscopic studies have been utilized to confirm the existence of η-O2 and to identify phase behavior and phase boundaries of β-, ϵ- and η-O2 at elevated temperatures ...
