Copy of: Abiogenic origin of methane: a neutron diffraction study
It has recently be demonstrated, through diamond-anvil cell experiments, that it may be possible for methane to be formed within the inner Earth through transformation reactions... -
High pressure effects on Jahn-Teller distortion in metal-formate perovskites
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... -
A High-Pressure investigation on 3,4,5-Trinitropyrazole
This proposal will explore the effect of elevated pressure on the 3,4,5-Trinitropyrazole (TNP). TNP releases a large amount of dinitrogen gas as a detonation product which is... -
Network compression and pressure-induced amorphisation in Zn(CN)2
Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour... -
Towards Neutron Scattering of Amorphous Materials in the Gigapascal Regime
Over the past few years, extensive developments have been made in the use of neutron diffraction for structural studies of liquids and amorphous materials at high pressure.... -
Investigation of caprolactam-d11 at high pressure
High pressure has shown to be a powerful tool for the exploration of the organic solid state. In particular one is able to perform polymerisation reactions on solid materials by... -
Non-uniform elastic deformation of layered crystal structures
The experiment will resolve a discrepancy between earlier experiments carried out very recently by us and work elsewhere on the hydrostatic compression of a series of 211... -
Search for magnetic ordering in the high pressure metallic state of LuNiO3 & ...
It has very recently been shown that Mott-insulators located at the crossover regime closer to the itinerant side, such as RNiO3, undergo a pressure-induced transition into a... -
Following the formation of Ho2Ge2O7 pyrochlore using high-pressure neutron di...
When synthesised at high pressure and temperature, holmium germanate adopts the pyrochlore structure. Because of its geometry, materials with this structure often have exotic... -
Ultra-rapid microwave materials synthesis in-situ; a microwave reactor for ti...
Microwave techniques are of interest to the materials chemistry community as they allow access to new metastable materials, and offer synthetic routes that are considerably... -

Over the past few years, extensive developments have been made in the use of neutron diffraction for structural studies of liquids and amorphous materials at high pressure.... -
High-pressure, high-temperature studies of energetic materials - FOX-7, CL-20...
The aims of this proposal are to explore the high-pressure, high-temperature behaviour of 3 important energetic materials - FOX-7, CL-20, and ADN. These experiments are expected... -
Understanding the "post-perovskite" structure (II): the Behaviour of CaPtO3 a...
Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present throughout all of the lower mantle:... -
Pressure response of CoMnSi: an anisotropic metamagnet with giant magnetoelas...
We wish to use elastic (this experiment) and inelastic neutron scattering (experiments on MARI and MERLIN submitted in this round) as an approach to quantify the change in... -
Mechanism of network collapse in strong network glass forming systems
The object of this proposal is to investigate the mechanism of network collapse in the ¿strong¿ network glass forming system GeO2 in the pressure range between 9 and 16 GPa... -
High pressure structural studies of halogen bonded systems
We propose a high-pressure neutron powder diffraction study of three halogen-bonded complexes, namely trimethylamine:ICl, 1,4-dioxane:(IBr)2 and pyridine:IBr. These are some of... -
Towards the Calibration of Chemical Pressure
The application of hydrostatic pressure allows the precise tuning of atomic separations, which control electronic structure and virtually all the interatomic interactions that... -
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...
