3D neutron TOF diffraction imaging
We propose to use SXD for mapping the crystallographic phases in an extended 3D benchmark object. The phase distribution will be reconstructed using a geometrical aberration... -
Understanding the mechanism of benzyl alcohol oxidation using supported Au-Pd...
Gold, in its nano-scale, has been found to be very effective catalyst for oxidation reactions. More recently, it was shown that supported Au-Pd catalysts can be used for... -
The high-pressure structures of carbon dioxide hydrate
The gas hydrates offer potential as hydrogen and carbon dioxide storage materials for use either in transport applications or for carbon sequestration. We have discovered a... -
High pressure polymorphism in ammonium bicarbonate, (ND4)DCO3
In an earlier high-pressure survey of the P,T phase diagram of deuterated ammonium carbonate, we observed changes in the neutron powder diffraction patterns that are consistent... -
Nuclear quantum effects and ortho-to-para conversion for hydrogen adsorbed in...
Metal-organic frameworks represent one of the most studied options to store hydrogen for clean-energy applications. Nuclear quantum effects, and in particular zero-point... -
High-pressure structure of magnetite nanoparticles
One way in which nanoparticles may differ from bulk properties are in terms of their response to pressure, but at the present time there have been very few structural studies of... -
High-pressure neutron diffraction studies of valence transitions in ACu3Fe4O12
Two new A-site ordered perovskite structure oxides, CaCu3Fe4O12 and LaCu3Fe4O12, were recently synthesized under high-pressure and high-temperature conditions in Kyoto. These... -
Neutron Compton Scattering Study of the Co-Nonsolvency Effect
(RB1010481) Neutron Compton Scattering, experiments were done on samples of poly-N-isopropylacrylamide dissolved in D2O, CH3OD and a mix of both solvents. This is of interest... -
Uranyl carbonates under pressure
The recommended method for storage of spent nuclear fuels is in an underground repository for 100,000 years. Under the long timescales, containment will fail and radioactive... -
Unravelling the temperature-pressure phase diagram for the multiferroic, BiFeO3
Bismuth ferrite is arguably the most widely studied multiferroic material due to room temperature magnetic and ferroelectric ordering. However, despite extensive research the... -
Equation of state of ice VI
Ice VI is likely to be a major mantle mineral in the interiors of large icy moons in our solar system, and in large icy extrasolar planets. It is also a common accessory phase... -

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,... -
Continued studies of the temperature-pressure phase diagram of BiFeO3
Bismuth ferrite is the most widely studied multiferroic material primarily due to the observation of both room temperature magnetic and electric ordering. Despite extensive... -
High pressure studies of the gillespite-structured phase Ba0.5Sr0.5CuSi4O10
We propose to study the pressure-dependence of the crystal structure of the alkaline earth copper phyllo-decaoxotetrasilicate Ba0.5Sr0.5CuSi4O10 to compliment our earlier... -
New high pressure hydrates for energy applications.
The need to decarbon the energy economy is one of the greatest technological challenges mankind has ever faced. Gas hydrates offer new clean potential materials for hydrogen... -
High-pressure studies of insenitive explosives: 2,4-dinitroanisole (DNAN) and...
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of 2 important energetic materials - 2,4-dinitroanisole (DNAN) and nitrotriazalone (NTO).... -
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...
