Locating transition metals in the apatite structure
Apatites are currently of major interest in a number of fields: biomaterials, solid oxide fuel cells, catalysis, environmental remediation to name a few. Hydroxyapatite -... -
Ferroelastic transitions in quantum critical tetragonal tungsten bronzes
Tetragonal tungsten bronzes have three types of channels for ions with the smallest unusually occupied with Li in potassium lithium tantalate (KLT). This creates complexity... -
The interpenetration of two poly(ethylene oxide) polymer brushes under confin...
Coating two surfaces with polymer brushes has been shown on many occasions to reduce friction by orders of magnitude. These ultra-low frictions are believed to stem from be the... -
Sensing SO2 in Robust Porous MOF Materials via Simultaneous Microwave Dielect...
We seek to develop new MOFs for sensing and removal of toxic gases (e.g., SO2) and request 4 days on POLARIS to study the structural binding details and dielectric data... -
Structure of Molecular Hydrogen in High Charge Pillared Clays
In this proposal we aim to study low temperature structure of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual motivations for this... -
Structure Sequence in Ca(1-x)Nd2x/3TiO3 Ceramics
Microwave dielectric ceramics are used in communications devices. Such materials need high relative permittivity, high dielectric quality factor and be temperature stable.... -
Determination of the structure of SiO2-rich aqueous fluids at high temperatur...
Many geological processes are governed by the migration of hot, mineral-rich water. These "hydrothermal" fluids are stable at high pressures and temperatures and are important... -

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... -
Equation of state and phase transitions of the cubic NTE material Cd(CN)2 - c...
Cubic cadmium(II) cyanide shows the most pronounced isotropic negative thermal expansion (NTE) effect known, with behaviour more than twice as extreme as that of better known... -
Investigation of the relevant thermodynamic parameters for the production of ...
With fantastic flux gains over its liquid conterpart, a solid methane moderator is essential to the newly built Second Target Station at ISIS. Unfortunately, it is notoriously... -
A high temperature neutron powder diffraction study of the crystal structures...
Cu2ZnSnS4 (CZTS) is a solar cell material of great interest. However the material whenfabricated, although of high symmetry, contains substantial defect concentration and a... -
Investigation of the magnetism and multiferroic properties in the MOF Cu--gua...
Multiferroic materials which exhibit both ferroelectric and (anti)ferromagnetic ordering are of great technological importance offering the potential for the design of novel... -
Hydrogen from ammonia using lithium imide metal nitride composites
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... -
IN-SITU NEUTRON DIFFRACTION STUDIES OF METAL-HYDRIDE HYDROGEN STORAGE MATERIALS
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... -
In-situ neutron powder diffraction studies of non-stoichiometry in Na battery...
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... -
Basic Science for Offpsec : Part 2
This proposal is part 2 of a set of two proposals on Offspec aimed at understanding some of the effects seen in off-specular data and in particular the use of the spin echo... -
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... -
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... -
Order-Disorder in A New Generation of Ceria-Zirconia Catalyst Supports
This proposal is concerned with understanding the properties of materials used in important applications in catalysis and energy, such as in molecular transformations of exhaust...
