A variable temperature study of polymorphism in Li2MSiO4 electrode materials
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 Interaction of Ammonia with Binary and Ternary Nitrides
We request 2 days on GEM in conjunction with the IGAn apparatus to investigate the formation of lithium amide (LiNH2) from the interaction of Li3N with ammonia (ND3), and the... -
Structural phase transitions in Li doped AgNbO3.
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... -
The crystal structure and thermal expansion of orthorhombic NiSi
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... -
Understanding the decomposition of ammonia by lithium-calcium imide
Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data... -
Phase transitions in Sr-doped multiferroic bismuth ferrite
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... -

Hydrogen production from ammonia using lithium imide: an isotope study
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... -
The high temperature phases of multiferroic YMnO3
Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal... -
Investigation of the low temperature phases of SrSnO3
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... -
The possibility of strongly ferromagnetic austenite in a stainless steel
It is generally accepted that austenitic steels (fcc) show no ferromagnetic signature. However, thermomagnetic measurements suggest an unexpected ferromagnetic transition (Tc =... -
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... -
Ammonia adsorption studies of Li(11)BD4 and Mg((11)BD4)2
On exposure to ammonia, LiBD4 and Mg(BD4)2 form the respective ammoniates, Li(11)BD4(ND3)n and Mg((11)BD4)2(ND3)6. We have identified the decomposition temperatures, kinetics... -
Amorphous content of alpha alumina
Powder diffraction offers an accessible and accurate method to determine the phase abundance in crystalline mixtures. Unfortunately, only the crystalline components of the... -
Possible high-temperature polar phases in the [110] layered perovskites NdBaI...
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... -
Investigating the ammoniation of light metal hydrides for hydrogen storage ap...
Light-metal hydride and amide systems are currently among the most promising materials for reversible hydrogen storage. In this proposal, we ask for 3 days on POLARIS or GEM to... -
Strain/order parameter coupling and anomalous elastic properties of Sr(Ti,Zr)...
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... -
