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... -
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... -
calcite water interface
The interface of CaCO3 (calcite) and water is of paramount importance in a number of key academic and industrial areas, including scale deposition in domestic and industrial... -

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... -
Impact of Jahn-Teller Distortions in Sr0.5Pr0.5MnO3
We propose to use the HRPD to establish the sequence of structures, and the nature of the transitions between these, in two complex manganites Sr0.5Pr0.5MnO3 and... -
In-Situ Study of Self-Recovery in MAX Phases
MAX phases exhibit a unique combination of the characteristics ofboth ceramics and metals coupled with an unusual combination of mechanical, electrical and thermal properties.... -
Muonium Defect Levels in 4H Silicon Carbide
We propose to obtain the temperature dependence of the diamagnetic spin-precession amplitudes up to 1100 K for the three electrical types of 4H-SiC in order to extract the Mu... -
Anion order in perovskite oxynitrides
Transition metal oxynitrides with perovskite type structures are an emerging class of materials with optical, photocatalytic, dielectric and magnetoresistive properties that may... -
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... -
Crystal structure and phase transitions of Sr2IrO4
Sr2IrO4 is an important material in the field of condensed matter physics, being a proposed J_eff=1/2 Mott insulator. Recent publications have shown that the reported low- and... -
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... -
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... -
Understanding the Pressure Response in Amines: Weak hydrogen-bonding vs Non-b...
Methylamines are an ideal chemical system to study in order to understand the effects of steric bulk and competing non-bonding interactions on hydrogen bonding at the networks...
