A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound...

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...

The application of hydrostatic pressure allows the precise tuning of atomic separations, which control electronic structure and virtually all the interatomic interactions that...

This proposal will explore the effects of elevated pressures and temperatures on the structures of an energetic co-crystal containing nitroguanidine (NQ)and an energetic salt...

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...

Lead scandium niobate (PSN) belongs to the class of perovskite-type relaxor ferroelectrics, which are among the key functional materials. Due to their structural complexity, the...

Recently we studied L-alanine to 9.85 GPa. This is the highest pressure for which structural data are available for any organic system larger than methane. The results enabled...

One of the aims of this proposal is to quench to ambient pressure a metastable form of the widely used secondary explosive RDX. This is formed above ~4.5 GPa and 448 K but is...

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....

We propose a high-pressure powder neutron diffraction study of the archetypal donor-acceptor complexes (CD3)3N...I2 and (CD3)3N...ICl . These are the simplest structurally...

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....

This proposal seeks to identify and characterise high-pressure polymorphs of the energetic materials hydroxylammonium perchlorate, CL-20, diaminodinitroethene (FOX-7), and...

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...

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...

Previous studies have suggested that a high-pressure form of the widely used secondary explosive RDX can be obtained above ~4 GPa and 488 K. This phase is reported to be...

This proposal seeks to identify and characterise high-pressure polymorphs of the energetic materials hydroxylammonium perchlorate, CL-20, diaminodinitroethene (FOX-7), and...

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...

The family of guanidinium metal formates has the perovskite structure and, like many perovskites, is of interest for these materials' magnetic and electric properties, in...

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...

BiCoO3 is a perovskite type material recently prepared by high pressure-high temperature synthesis in Kyoto. It has a distorted acentric perovskite structure with order of high...
