High-pressure studies of energetic materials
This proposal seeks to identify and characterise high-pressure polymorphs of the energetic materials hydroxylammonium perchlorate, CL-20, diaminodinitroethene (FOX-7), and... -
High-pressure and high-temperature studies of N-guanylurea dinitramide (FOX-1...
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of 2 important energetic materials - N-guanylurea dinitramide (FOX-12) and... -
High-pressure studies of inorganic azides
This proposal seeks to identify and structurally characterise the high-pressure phases of the azide salts of sodium, silver, lead, and the ammonium ion. Azides are examples of... -

Pressure and Temperature-Induced Phase Transformations in PbZrO3-BiFeO3 Ceramics
The proposed experiment involves identification of the phase boundaries and determination of the crystal structures of PbZrO3-BiFeO3 (PZ-BF) ceramics as a function of... -
The Pressure and Temperature Dependence of the Structure of Ammonium Triiodide
We have shown that the molecular ionic solids MI3 (M=Tl, Cs, Tl, NH4) undergo structural phase transitions below 3.4 GPa at RT to give the same new high pressure phase (HP) with... -
A high-pressure study of N,N'-dimethylurea
This proposal seeks to explore the high-pressure structural behaviour of N,N¿-dimethylurea. Two new high-pressure forms have been structurally characterised using x-ray methods,... -
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...
