Structure and stoichiometry in new nitride catalysts; anion mobility, chemica...
Our studies focus on the use of Co3Mo3N (331) as a catalyst in ammonia synthesis. During synthesis, N is lost and the compound is transformed to the new nitride Co6Mo6N (661); a... -
Characterisation of the gamma prime precipitate distribution in an advanced N...
The excellent high temperature properties of Ni-base superalloys are derived from the presence of fine precipitates of the intermetallic Ni3Al phase, termed gamma prime. The... -
muSR in the presence of significant spin-orbit coupling
The great majority of known muonium defect centres and muonium substituted organic radicals have essentially spin-only magnetism, with few exhibiting any noticeable departure... -
Decomposition studies of Li(1-x)NaxND2, LiNa2(ND2)3 and Li3Na(ND2)4
We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the... -
Oxygen Vacancy Clusters in Pure and Doped CeO2-d
Oxide ceramics based on ceria, CeO2, have been the subject of considerable research for the role of solid electrolyte within solid oxide fuel cells (SOFCs), since their ionic... -
Nanophase separation in monolayers of stratum corneum mixtures
There is considerable effort being put into the modelling of the outer layer of skin, the stratum corneum, because of impending EU restrictions on the use of animal skin for... -
Thermal ionization of bond-centred muonium in diamond
Our previous LF-µSR measurements in natural type Ia single crystal diamond showed some evidence of the ionization of bond-centred muonium (MuBC) from around 1000K. This was... -
Inelastic magnetic scattering in CePd3
CePd3 is a classic intermediate valence (IV) system. In MAPS experiment 620167 we obtained an important qualitative result for CePd3, namely that the Kondo-like scattering... -
Spin Dynamics in the Quantum Critical and Ferromagnetic Regimes of URu2-xRe
Recently, there has been a significant amount of interest in quantum phase transitions and non-Fermi liquid (NFL) behavior exhibited by heavy-fermion compounds. Interestingly... -
Enhanced oxygen hyperstoichiometry in Y doped La9.33+xGe6O26+3x/2
Apatite-type lanthanide silicates/germanates have been attracting considerable interest as a new class of oxide ion conductors. The presence of interstitial oxide ions is... -
O/N-distribution in host lattices for rare-earth doped phosphors in light emi...
Nitridosilicates and oxonitridosilicates (sions) gain more and more importance as host lattices for rare-earth doped phosphors in light emitting diodes. By means of... -
Adsorption of modified PEI / SDS mixtures at the solid-solution interface
Polymer-surfactant mixtures are extensively used in a wide range of domestic, industrial and technological applications. This proposal is part of a collaboration between Oxford... -
Evolution of complex surface structures in LAS / nonionic surfactant mixtures
This proposal is part of a broad programme of collaborative research between RAL / Oxford and Unilever, using predominantly scattering techniques to investigate the nature of... -
Investigation of the impact of mechanical twinning on the thermal expansion b...
We request three days of beam-time on POLARIS to investigate the influence of thermally-induced twinning on the thermal expansion behaviour of polycrystalline calcite....
