Tetragonal R(Fe,M)12 compounds (R=rare earth, M transition metal or Si), with the ThMn12 structure, are good candidates as permanent magnet materials with reduced R content....

The aims of the present proposal are twofold. Firstly to use very high resolution neutron diffraction data to establish accurate and precise structures of the novel...

NiSi is a technologically important material that is also of interest to Earth Scientists because of the possible role of Ni and Si in the Earth¿s core. It crystallises in the...

In this proposal we request 3 days of beam time on HRPD to study the structure and phase transitions of XNbOP2O7 (X = Rb and ND4). These materials have been shown to undergo...

Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data...

A vast amount of work has been conducted on understanding metal organic frameworks (MOFs) in their powder form. However, for use in industrial processes, powders will need to be...

We have recently discovered that light metal amides and imides are excellent cattalysts for the decomposition of ammonia. We request 3 days on POLARIS to perform in situ neutron...

This proposal aims to study the potential for neutron diffraction to offer spatially-, chemically-, and temporally-resolved information on a dynamic system, in this case the...

The present proposal is to examine the low temperature structural properties of SrSnO3 using the HRPD. This work aims to examine the structural basis for the unusual low...

It is generally accepted that austenitic steels (fcc) show no ferromagnetic signature. However, thermomagnetic measurements suggest an unexpected ferromagnetic transition (Tc =...

We seek to develop new materials for sensing and removal of toxic gases (esp., SO2) and request 2 days on POLARIS to study the structural binding details and dielectric data...

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 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...

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...

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...

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...

Thermoelectricity enables the conversion of waste heat into useful power, and it is becoming increasingly important for power recovery applications at high temperature, where...

Ab initio computer simulations have suggested that pre-melting phenomena occur in the elastic properties of hcp-iron at the conditions of the Earth’s inner core just before...

We request 3 days on POLARIS to study the detailed crystal structure of a sodium battery cathode material that is currently under consideration for use in commercial sodium...

Recently [RB 900007], we have demonstrated that it is possible to determine the detailed site-by-site behaviour of hydrogen during in-situ absorption and desorption in metal...
