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... -
Hydrogen Disorder in the molecular complex 5-fluorocytosine: 3,5-dinitrobenzo...
As part of our program in understanding hydrogen bonding systems, exploiting crystal engineering in our synthesis of complexes containing desired HB motifs, we investigate... -
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... -
Ion Exchange and Dehydration in Clinoptilolite
Determination of the position of hydrogen in inorganic materials such as zeolites, coordination compounds, H2 storage materials, energy materials, organometallics etc is a... -
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... -
Phonon Density of States in Nanocrystalline YAG:Cr
Here we propose to measure the phonon density of states in nanocrystalline samples of YAG:Cr. Our parallel luminscence measurements have revealed dramatic changes in the phonon... -

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... -
Spin ordering in the iridium oxide pyrochlore A2Ir2O7
Here we propose to search for magnetic order in 3 variants of the A2Ir2O7 (A=Y, Nd, and Lu) system. A fundamentally new, moderately-coupled, electronic ground state has been... -
Visualisation of Multi-component Ion Exchange for Oil Recovery
Release of oil bound to clay minerals by exchange of bridging cations for non-bridging ones is postulated as a major mechanism for enhanced oil recovery. In this work we propose... -
Variable Temperature studies of an anomalous proton sponge benzoic acid co-cr...
As part of a long-running programme, we have identified many co-crystallisation systems producing hydrogen-bonded molecular complexes yielding fascinating X-ray diffraction and... -
Spin Excitations and "Hourglass" Dispersion in the Model High-Tc superconduct...
The unique "hourglass"-type dispersion observed within several classes of hole-doped cuprates has garnered considerable theoretical and experimental interest. Here we propose to... -
Accurate H atomic parameters for charge densities in polymorphic materials
Polymorphism is a common feature of many molecular materials The "Holy Grail" would be the ability to predict the appearance of polymorphism in a particular molecular system,... -
Modifications to the phonon spectrum of nanocomposite thermoelectrics
Here we propose to use the superior energy resolution of OSIRIS to measure the phonon desnity of states (PDOS) of both nanocomposite and bulk thermoelectric alloys of Si1-xGex....
