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,... -
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... -
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... -
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... -
Pressure effect on high-temperature multiferroic CuO studied by a single crys...
We propose to perform neutron diffraction experiment under high pressure condition, using a single crystal of CuO on WISH beamline. This monoxide is known as a multiferroic... -
Relaxor-like dielectric behaviour in stoichiometric Sillenite Bi12SiO20
We request 1 day of beam-time on POLARIS to collect Neutron Diffraction (ND) data on the Sillenite Bi12SiO20 (gamma-Bi2O3) that we have recently discovered to exhibit a... -
Cation site disorder in KTiOPO4 isostructures
KTiOPO4 (KTP) is a well known non-linear optical material. Its crystal structure has highly asymmetric Ti-O bonds, a rigid TiO6-PO4 lattice and K cations trapped in cages. The... -

Investigating the role of Oxygen in the delafossite-spinel transformations in...
CuFe1-xCrO2 has potential applications as an SOFC cathode material. It exhibits and interesting transformation on oxidation. This is a follow on from our recent HRPD experiment... -
Formation of hard carbon from carbonized biowaste and in situ neutron study
hard carbon are promising anodes for sodium ion batteries, due to their high capacity and green production from biowaste. However, they require treatment at very high... -
Investigation of the low temperature phases of SrSnO3
The present proposal is to examine the low temperature structural properties of SrSnO3 using the HRPD. This work aims to examine the structural basis for the unusual low... -
Spatial, Chemical, and Temporal Resolution of Platinum-Catalysed Benzene Conv...
This proposal aims to study the potential for neutron diffraction to offer spatially-, chemically-, and temporally-resolved information on a dynamic system, in this case the... -
Investigation of pore filling via pseudo-condensation of supercritical hydrog...
This proposal aims to use NIMROD to glean information on the mechanisms of pore filling and to obtain a quantitative absolute value for the density of supercritical hydrogen... -
Does elastic twinning play a role in the thermal expansion behaviour of polyc...
We request two days of beam-time on POLARIS to obtain high resolution measurements of the thermal expansion of dolomite [CaMg(CO3)2]. The experiment forms part of a larger... -
The high temperature phases of multiferroic YMnO3
Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal... -
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... -
Improper ferroelectricity in hexagonal tungsten bronzes
Ferroelectrics are an important class of materials in modern electronics. Their application range from simple capacitors to ultrasonics transducers and sensors to memory... -
