High-pressure and high-temperature studies of CL-20, HMX, and TATB
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of 3important energetic materials - CL-20, HMX and TATB. These experiments are expected... -
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... -
A high pressure structural study of the charge transfer complexes of pyridine...
We propose a high-pressure powder neutron diffraction study of the simple donor-acceptor complexes (C5D5N)...ICl and (C5D5N)...IBr . These are the simplest structurally... -
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... -
Copy of: Pressure induced phase switching magnetic ordering in BiFeO3-PbTiO3
This experiment seeks to continue previous work on PEARL, whereby the phase is altered in the room temperature multiferroic BiFeO3 - PbTiO3 using hydrostatic pressure with the... -
A high-pressure study of monovalent bifluorides
This proposal seeks PEARL beam time to conduct the first high-pressure neutron diffraction study of the monovalent azides XDF2, where X = Na, ND4, Cs and Tl. In so doing, we... -
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... -
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... -
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...
