High-pressure studies of insensitive explosives: Nitroguanidine (NQ) and N-gu...
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of two insensitive energetic materials - Nitroguanidine (NQ) and N-guanylurea-dinitramide... -
A high pressure study of the alpha-form of acetylene dicarboxylic acid dihydrate
We propose to investigate changes that occur in acetylene dicarboxylic acid dihydrate as a function of pressure. This system, for which there is a general paucity of structural... -
PTM dependant polymorphism of acrylamide
Our recent X-ray and single crystal studies have shown that acrylamide can undergo different phase transformations depending on the pressure transmitting medium used i.e.... -
A High-pressure Study of the Crystal Structures of CsDF2, ND4DF2 & TlDF2
This proposal seeks PEARL and HRPD beam time to study the pressure and temperature dependence of the crystal structures of deuterated caesium, ammonium and thallium bifluoride.... -
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... -
The Effect of Pressure on the Crystal Structure of Serine Hydrate
Serine monohydrate undergoes a phase transition at 5.2 GPa which involves reorientation of water molecules. It appears that this disrupts H-bonding elsewhere in the crystal,...
