Investigation into the Effect of Heating Rates on Recrystallisation Mechanism...
Electrical steels (ES) used in motors and transformers. The major challenge is to optimise the magnetic property of ES to reduce energy waste during service. The... -
SHINING THE BEAM ON BONES: CHARACTERISATION OF BURNED AND FOSSILISED SKELETAL...
Neutron spectroscopy is applied to study bones exposed to anaerobic burning or fossilisation. The results thus obtained will complement previous data gathered by the team on... -
Ammonia synthesis using lithium hydride-metal nitride composites: an in situ ...
The development of more active catalysts for the production of ammonia will have a worldwide impact on the energy cost of producing fertiliser. Composites of lithium hydride and... -
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,... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we... -
Magnetic order in two pyrochlore iridates
Iridium oxides are of interest because many novel magnetic phases have been predicted in crystals, depending on the geometry of the crystal lattice. Our proposal concerns two... -
The ferroelectric phase transition in Dion-Jacobson layered perovskites - con...
Ferroelectricity in the Dion-Jacobson (DJ) family of layered perovskites arises from a 'trilinear coupling', whereby two non-polar lattice modes interact in such a way to... -
YMnO3-x : Mn(I) in a mixed metal oxide ?
Topotactic reduction of YMnO3 with CaH2 yields three new reduced phases. Two of these phases appear to have compositions close to YMnO2.5 but with very different anion vacancy... -
Understanding the "post-perovskite" structure (I): the Behaviour of CaPtO3 at...
Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present throughout all of the lower mantle:... -
Possible high-temperature polar phases in the [110] layered perovskites NdBaI...
Geometric ferroelectrics are an unusual and rare class of materials which exhibit spontaneous electrical polarisation due purely to 'geometric' effects, i.e. caused by atomic... -
Microstructural orientation mapping with a neutron beam
We propose to develop the means to measure the orientations, phases and strains of individual crystal grains within a polycrystal using neutrons. Such measurements have... -
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... -
Structural phase transition in SnSe with ultra low thermal conductivity
SnSe has recently been reported to have very good thermoelectric performance. This is linked to an ultralow thermal conductivity and occurs in the B-phase (ZT > 2 above 800... -
Variable temperature structural study of disordered La0.5Ba0.5CoO3-d; and lay...
The aim of the proposal is to investigate changes in the crystal structure of A-site disordered La0.5Ba0.5CoO3-d; and layered LnBaCo2O6-d; (Ln = La, Y) perovskites at... -
Can we use the H-H stretch of adsorbed dihydrogen to characterise materials?
The use of the J 0-to-1 rotational transition of dihydrogen has been extensively used to characterise the state if hydrogen in and on materials. The disadvantage of studying 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... -

Formation of Ho2Ge2O7 Pyrochlore at High Temperature and Pressure
When synthesised at high pressure and temperature, holmium germanate adopts the pyrochlorestructure. Because of its geometry, materials with this structure often have exotic and... -
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... -
