There is great interest in scaling up Li-ion batteries for use in electric vehicles, requiring cheap and safe cathodes. Recently, silicate-based cathodes have been described,...

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...

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

Bismuth ferrite, BiFeO3, is a much-studied ceramic showing both dielectric and magnetic ordering at relatively high temperatures. In order to improve its properties there has...

Multiferroic materials exhibiting at least two ferroic orders are the subject of extensive research due to many potential technological applications. Bismuth ferrite (BFO) is by...

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...

Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal...

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 =...

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...

Geometric ferroelectrics are an unusual and rare class of materials which exhibit spontaneous electrical polarisation due purely to 'geometric' effects, i.e. caused by atomic...

Advanced materials such as polycrystalline Ni superalloys put increased pressure on developing appropriate thermomechanical procedures, which avoid the generation of large...

Finely divided supported palladium particles are used as catalysts in many technical processes. Using MAPS we have recently investigated the interaction of hydrogen with the...

HRPD data will be collected in situ at low and high temperatures from perovskites belonging to the Sr(ZrxTi1-x)O3 solid solution which have recently been characterised for their...

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...

This proposal seeks to study three systems associated with heat-storage applications using in situ neutron powder diffraction. The first experiment will focus on a sample of...

Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to...

Ammonia has been proposed as a high density chemical energy-storage media, which can be safely and reversible stored within low cost saline halides. Here we propose to extend...
