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... -

Structural study of high pressure phases of multiferroic BiFeO3
BiFeO3 is a rare example of multiferroic material with a simple perovskite-like structure, having extremely large magnetic ordering temperature (TN = 650 K) and Curie... -
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,... -
pressure induced para-antiferromagnetic switching in the multiferroic BiFeO3 ...
We have shown using previous experiments that moderate hydrostatic pressures can be used to switch phase from tetragonal to rhombohedral in the material BiFeO3 - PbTiO3 at room...
