In situ diffraction studies of the archetypal network glass, SiO2 at high pre...
Silica glass is one of the most widely studies amorphous materials. It is the archetypal glass former, comprising a network of corner-shared SiO4 tetrahedra. Recently a lot of... -
In situ studies of the transition between high-density and very-high-density ...
The amorphous ices are good model systems for the study of pressure amorphisation and provide our princpal experimental test of the two liquids model of water. This seeks to... -

Structure of hot dense liquid carbon dioxide
We propose to study the structure of liquid CO2 by neutron diffraction under high pressure and high temperatures to 6 GPa / 800 K. Carbon dioxide belongs to the most fundamental... -
Structural determination of non-stoichiomentric phases Li2+yND for 0<y<1
In a series of in situ neutron diffraction measurements from deuterium up-take in Li3N, the present authors have identified a novel non-stoichiometric 'quasi-imide' of... -

Neutron scattering investigation of the influence of high hydrostatic pressur...
Amyloid fibrils are highly organized filamentous structures formed by the self-assembly of polypeptides. This proposal is to study the effect of pressure on the structure of... -
The high pressure structure of deuterium
Of all the stable elements hydrogen(deuterium) is the least well studied from a structural point of view. Not one of its crystal structures has been fully charecterised. This... -
Transformations in B2O3 glass under pressure
B2O3 is a prototypical glass forming oxide material and is an essential component in many industrial glasses. Unlike SiO2 and GeO2 its structure under ambient conditions is not... -
Mixed gas hydrates at high pressure
High pressure gas hydrates offer considerable potential for gas storage applications if methods can be devised to stablise them at lower pressures. This proposal is form... -
High-resolution phonon spectra of silicon nitride phases
Silicon nitride is a mechanically tough and light-weight ceramic material able to withstand high temperatures. It is therefore becoming increasingly attractive for use in... -
Polyamorphism in Glassy GeO2
The object of this proposal is to determine, by using neutron diffraction, the nature of the polyamorphic phase transition that occurs in glassy GeO2 with increasing pressure.... -

The hydrogen clathrates of hydroquinone and urea
The search for new hydrogen storage materials is of considerable importance given the need to develop a carbon-free energy economy. This proposal is to investigate the... -
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... -
The high pressure structures of lithium ammonia
Lithium ammonia is the lowest temperature liquid metal known and has been suggested as a candidate for high Tc superconductivity at high pressure. In earlier work at the ILL we... -

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... -
Contrast match on activated carbon: density and structure determination
At present there is a growing interest to porous carbon due to its large field of application. Porous activated carbons with their large surface area and microporosity are one... -
Pressure-induced changes in intermediate range order in the candidate polyamo...
This proposal is a continued exploration of the non-recoverable changes that have been reported in the structure of vitreous SiO2 when compressed. This proposed experiment will...
