Experimental and theoretical confirmation of an orthorhombic phase transition in niobium at high pressure and temperature
Daniel Errandonea, Leonid Burakovsky, Dean L. Preston +8
Compared to other body-centered cubic (bcc) transition metals Nb has been the subject of fewer compression studies and there are still aspects of its phase diagram which are unclea…
The effect of pressure on hydrogen solubility in Zircaloy-4
H. E. Weekes, D. Dye, J. E. Proctor +4
The effect of pressure on the room temperature solubility of hydrogen in Zircaloy-4 was examined using synchrotron X-ray diffraction on small ground flake samples in a diamond anvi…
Monazite-type SrCrO4 under compression
J. Gleissner, D. Errandonea, A. Segura +9
We report a high-pressure study of monoclinic monazite-type SrCrO4 up to 26 GPa. Therein we combined x-ray diffraction, Raman and optical-absorption measurements with ab initio cal…
Comment on: "The Frenkel Line: a direct experimental evidence for the new thermodynamic boundary"
V. V. Brazhkin, J. E. Proctor
In a recent publication (D. Bolmatov et al. Sci.Rep. 5, 15850 (2015)) the experimental observation of structural transformations on crossing the Frenkel line in supercritical argon…
Pressure coefficients of Raman modes of carbon nanotubes resolved by chirality: Environmental effect on graphene sheet
A. J. Ghandour, I. F. Crowe, J. E. Proctor +5
Studies of the mechanical properties of single-walled carbon nanotubes are hindered by the availability only of ensembles of tubes with a range of diameters. Tunable Raman excitati…
Formation of transition metal hydrides at high pressures
Olga Degtyareva, John E. Proctor, Christophe Guillaume +2
Silane (SiH4) is found to (partially) decompose at pressures above 50 GPa at room temperature into pure Si and H2. The released hydrogen reacts with surrounding metals in the diamo…
