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.... -
High-Pressure Structural Behaviour of 2,2,2-trifluoro-ethanol
In the mono-alcohols (ROH) there is a competition between the packing requirements of the R-group and for the hydroxyl groups to be sufficiently close for hydrogen bonding to... -
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... -
Copy of: Division of the supercritical fluid state into liquid- and gas-like ...
In recent years, the long-standing belief that beyond the critical point, matter exhibits no clear transition between liquid-like and gas-like states has been questioned. A line... -
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.... -
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... -
The hypersensitivity of the water phase diagram to ammonium fluoride doping
Water displays a highly complex phase diagram that is key to a range of critical processes, from the evolution of icy moons to that of the Earth's hydrosphere and even of life... -
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... -
Investigation of the multiferroic materials Ba3Dy2GaNb9O30 and Ba3.5Dy2Ga1.5N...
We have recently performed a ZF muon experiment on Ba3Dy2GaNb9O30 in EMU under the influence of electric fields and demonstrated that this material demonstrates multiferroic... -
Neutron Powder Diffraction Studies of Gas-loaded NOTT-300 Materials for Energ...
The development of new porous metal-organic frameworks (MOFs) is receiving considerable attention owing to their potential for energy-efficient gas storage and separation. We... -
calcite oil interface
The interface of CaCO3 (calcite) and oil is of paramount importance in a number of key academic and industrial areas, not least oil recovery. Neutron reflection has proved to be... -
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... -
30 T High Magnetic Field Neutron Diffraction on Multi-ferroic TbMnO3
The main target of the proposal is to determine the magnetic phase diagram of multi-ferroic compound TbMnO3 in extremely high magnetic fields around 30 T by using a pulsed... -
Further studies of the Mg(BH_{4} )_{2} and parahydrogen
We found evidence of solid para-hydrogen absorbed in Mg(BH_{4} ){2} up to temperatures of 195 K. Para hydrogen was dosed in Mg(BH{4} )_{2} at 50 K. A series of dosings were... -
Understanding deep-Earth mineralogy: The crystal structure of CaSiO3 perovskite
CaSiO3 perovskite is the third most abundant mineral in the Earth's lower mantle (below 670 km). It also occurs as a major phase at lower pressures and temperatures in...
