Exotic centrosymmetric phase of acentric urea under high pressure
Haw-Tyng Huang, Yedukondalu Neelam, Mei-Shuan Cheng +6
Urea is a simple prototype supramolecular crystal that exhibits rich polymorphism at low pressure due to broken and restored N-H-O hydrogen bonds. The high pressure polymorph (phas…
Ultra-fast yttrium hydride chemistry at high pressures via non-equilibrium states induced by x-ray free electron laser
Emily Siska, G. Alexander Smith, Sergio Villa-Cortes +24
Controlling the formation and stoichiometric content of desired phases of materials has become a central interest for the study of a variety of fields, notably high temperature sup…
Expanded Comment on: Optical Properties of Fluid Hydrogen at the Transition to a Conducting State
Isaac F. Silvera, Rachel Husband, Ashkan Salamat +1
We comment on a recent paper published by McWilliams et al claiming that high-pressure/high-temperature hydrogen is a semi-conductor or semi-metal, in conflict with all earlier mea…
One-dimensional chain "melting" in incommensurate potassium
Emma E. McBride, Keith A. Munro, Graham W. Stinton +4
Between 19 and 54 GPa, potassium has a complex composite incommensurate host-guest structure which undergoes two intraphase transitions over this pressure range. The temperature de…
Structural Changes in Thermoelectric SnSe at High Pressures
I Loa, R J Husband, R A Downie +2
The crystal structure of the thermoelectric material tin selenide has been investigated with angle-dispersive synchrotron x-ray powder diffraction under hydrostatic pressure up to…
The Structure of Eu-III
R. J. Husband, I. Loa, G. W. Stinton +3
Previous x-ray diffraction studies have reported Eu to transform from the hcp structure to a new phase, Eu-III, at 18 GPa. Using x-ray powder diffraction we have determined that Eu…
