Improper ferroelectricity in hexagonal tungsten bronzes
We address the detailed atomistic mechanism of ferroelectricity in a new family of oxides typified by the composition CsNbW2O9. Contrary to the mechanism in most ferroelectrics,... -
Examining the structural effects of non-stoichiometry in lithium amide-imide
The solid solution between lithium amide and lithium imide plays important roles in both ammonia decomposition catalysis and solid state hydrogen storage. In order to understand... -

Structural and Magnetic Behaviour of PrCrO3 at High Pressure
The application of hydrostatic pressure tunes the interatomic separations within a compound, causing changes in the electronic structure. This alters many other material... -
Environmental Apatites
Materials adopting the apatite structure are gaining an increasing importance as potential solid-oxide fuel cell electrolytes and for the chemical stabilisation of high level... -
Superstructure in bismuth rich substituted bismuth oxides
A study of superlattice ordering in substituted bismuth oxides is proposed. Bismuth rich compositions at the 14:1 B:M (where M = W/La and Ta) ratio will be investigated. These... -
Structures of new n-type thermoelectric oxides
Thermoelectric materials (TEs), which produce a voltage in response to an applied temperature gradient, are set to play an increasingly important role in the development of new... -
Order and disorder in sodium amide
Sodium amide has recently attracted interest as a catalyst for the decomposition of ammonia as a means of producing hydrogen. As such, its properties are of increasing relevance... -
The definitive Bi4Ti3O12: a textbook example of Hybrid-Improper Ferroelectricity
Bi4Ti3O12 is a well-known and studied layered perovskite; such phases are ferroelectrics, which have been used in random-acccess memories and other applications. Understanding... -

H/D isotope effect on enantiomers: the case of Alanine
In the current description of any molecular system based on the Schrodinger equation with a Hamiltonian accounting only for the electromagnetic forces, the structural properties... -
The application of INS to investigate the methanol-to-gasoline reaction over ...
We propose to use MERLIN to measure INS from commercial zeolite catalyst samples extracted from a reactor in which they have been exposed to dimethylether for different lengths... -
Cation substitution in synthetic meridianiite (MgSO4.11D2O): phase behaviour ...
MgSO4.11H2O (MS11) is the most highly hydrated phase in the binary MgSO4¿H2O system. Whilst lower hydrates in this system have end-member analogues containing alternative... -
Coupled magnetic and nematic fluctuations in S-doped FeSe
Iron selenide (FeSe) is the simplest of the iron-based superconductors. It has a nematic (tetragonal to orthorhombic) phase transition at T = 90K. Upon doping with sulphur, the... -

High resolution powder diffraction on Sm based pyrochlores
Magnetic frustration is a hot topic in solid state physics, mainly due to the topological new phases of matter that frustration mechanisms can drive (vide Physics Nobel Prize... -
Structural characterisation of chemisorbed methoxy in ZSM5: an intermediate i...
Zeolites and zeotype materials are well established in the field of catalytic science. Particularly notable is their use for shape selective, acid-catalyzed conversions of... -

Structural Distortions in the Spin Ladder Compounds Ba2CuTe1-xWxO6
Ba2CuTeO6 has garnered considerable interest as the combination of stacking sequence and Cu2+ displacements lead to a magnetic geometry that reproduce the effects of a spin... -
Towards an improved understanding of the active phase of iron based Fischer-T...
The applicants have recently completed a series of INS studies on a model iron Fischer-Tropsch catalyst. That work established that different sample pre-treatments could...
