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... -
Determination of the Thermoelastic Properties of Jadeite
Jadeite, NaAlSi2O6 is an important mineral in metamorphic rocks and occurs in low as well as high metamorphic grade. Previously we have determined the thermoelastic properties... -
A High pressure investigation of the Binary carbonyls of group 7 M2(CO)10 M =...
The structures of two binary metal carbonyls containing a metal-metal bond Mn2(CO)10 and Re2(CO)10 will be studied as a function of pressure. Both these molecules undergo a... -
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... -
Copy of: The Effect of Pressure on the Crystal Structure Titanium Tetrachloride
At ambient pressure and temperature TiCl4 is a fuming yellow liquid. On cooling it forma a solid composed of essentially isolated tetrahedral molecules; the same structure is... -
Insulator to metal transition in TiOCl at high pressures
We propose to study the high temperature structure of TiOCl where a pressure induced metal to insulator transition has been reported recently by Kuntscher et al.Due to our... -
Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crystal. There have been no... -
The effect of pressure on the hydrogen bonding in ammonium formate
We propose to investigate the changes that occur in the structure of ammonium formate as a function of pressure. This is the simplest system in which the oxygen atoms of a... -

LOW DIMENSIONAL NETWORKS UNDER PRESSURE. IN-SITU DIFFRACTION MEASUREMENTS OF ...
Carbonate liquids are characterised by low temperature and low viscosity and play an important role in molten carbonate fuel cells, battery electrolytes and, surprisingly, in... -
Investigation of glycolide-h4 and d4 at high pressure.
This proposal seeks to investigate the polymorphism and polymerisation of glycolide. Glycolide is a six-memebered ring structure that polymerises into poly(glycolic acid) and is...
