Ammonia synthesis using lithium hydride-metal nitride composites: an in situ ...
The development of more active catalysts for the production of ammonia will have a worldwide impact on the energy cost of producing fertiliser. Composites of lithium hydride and... -
The Crystal Structure of a New Hydrogen Hydrate
Hydrogen hydrates are good potential hydrogen storage materials because they are both cheap and environmentally passive. This proposal is to study the crystal structure and... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we... -
Characterisation of the hydrides in Stryker¿s reagent
In recent years, soluble derivatives of CuH prepared by non-aqueous routes have become important as mild reducing agents, one such compound, Stryker¿s reagent [Ph3PCuI]6. The... -
Understanding the "post-perovskite" structure (I): the Behaviour of CaPtO3 at...
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:... -
Mechanism of hydride-ion mobility in a novel oxide-hydride
This proposal requests 7 days of beamtime on the quasielastic neutron scattering spectrometer OSIRIS to investigate the mechanism of hydride ion mobility in the recently... -
Copy of: Magnetic excitations in the one dimensional (1D) spin-chain systems:...
The spin-chain systems with general formula A¿3ABO6, crystallizing in the K4CdCl6 type structure has attracted a lot attention in recent years due to geometrical frustration... -
Water dynamics in porous PTFE membranes for water purification
This is a resubmitted proposal in a new project on water purification by membrane distillation. With this technology liquid water is excluded from passing the separating... -
Intercalation of Ciprofloxacin into Lithium - Fluorohectorite at acid and bas...
Using quasielastic neutron scattering (QENS) we will investigate the intercalation of Ciprofloxacin (CIPRO) into the synthetic clay Lithium Fluorohectorite (LiFh) to... -
Ba3MoNbO8.5 novel oxide ion conductor: Direct observation of oxide ion dynamics
Oxide ion conductors are researched as electrolytes in solid oxide fuel cells. Yttria-stabilized zirconia is the currently used electrolyte in SOFCs, leading to high operating... -
Microstructural orientation mapping with a neutron beam
We propose to develop the means to measure the orientations, phases and strains of individual crystal grains within a polycrystal using neutrons. Such measurements have... -
Compositional analysis and working technique determination of five Japanese T...
The Pitt Rivers is Oxford University¿s museum of anthropology and world archaeology. The Japanese material includes a large number of items of metalwork. Amongst these, the... -
The effect of electron-phonon coupling on the nuclear dynamics of MgB2
We propose a spectroscopic experiment to characterise the effect of electron-phonon coupling on the nuclear dynamics of Mg and B in the the MgB2 superconductor. The... -
Shifting the tricritical point in CoMnSi
We have a long-standing interest in the temperature- and magnetic field-evolution of magnetic and crystal structure in CoMnSi. This is driven by an interest in the... -
Structural origin of negative thermal expansion in ScF3
Scandium fluoride has recently been identified as a very simple example of a material showing negative thermal expansion over a wide range of temperatures. In particular, it... -

Excitation spectrum of isotope-enriched Sr2IrO4
Sr2IrO4 is an important material in condensed matter physics, having been discovered to host a novel Jeff=½ Mott insulating state.Yet while magnetic fluctuations play a crucial... -
Thermal expansion of kyanite, andalusite and sillimanite
Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the... -
Thermal expansion of Mg: pre-melting effects in hcp metals and the Earth's in...
Ab initio computer simulations have suggested that pre-melting phenomena occur in the elastic properties of hcp-iron at the conditions of the Earths inner core just before... -
Pressure-Tuning Interactions in Spin-Crossover Metal-Organic Frameworks
The magnetism of spin-crossover (SCO) materials containing Fe(II) can be switched by changing conditions. The low-spin state existing at low temperature or high pressure can be...
