Compressibility and Tilting of Polyhedra within Sr2NiMoO6 at High Pressure
Ordered double perovskites (also known as elpasolites) have the general formula A2BBO6 where A is generally a rare earth metal or alkaline earth metal and where B and B are... -
Local ordering in the pressure-induced order-disorder transition in ammonium ...
Ammonium bromide undergoes a pressure-induced order-disorder transition, where the disordered (plastic) phase is thought to consist of a random distribution of ammonium cations... -
The quest for fully hydrogen-ordered ice XIV
Water ice displays a remarkably complex phase diagram containing pairs of hydrogen-ordered / disordered phases. Ice XII is a hydrogen-disordered phase and ice XIV is its... -

High-pressure structure of ferrosilite FeSiO3 glass
The density-driven structural transformations in ferrosilite glass FeSiO3 will be investigated at pressures increasing to 17.5 GPa. This glass is one of a family of silicate... -
High pressure charge transitions in PbCoO3
PbCoO3 used to be the missing link in the PbMO3 perovskite series. PbCoO3 was recently synthesized by the Azuma group using high-pressure synthesis at 12 GPa. NPD at JPARC... -
Phase Behaviour in Pyrazine and Tetramethylpyrazine.
Pyrazine-I is stable < 302 K, phase II exists from 302-310 K, and phase III from 310-324 K. The known phase-I forms an ordered structure. It is thought that structures of... -
