In conjunction with an industrial partner (Sasol Technology), it is proposed to apply INS to characterize a series of prototype Fischer-Tröpsch synthesis (FTS) catalysts that... -
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... -
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... -
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 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... -
The possibility of strongly ferromagnetic austenite in a stainless steel
It is generally accepted that austenitic steels (fcc) show no ferromagnetic signature. However, thermomagnetic measurements suggest an unexpected ferromagnetic transition (Tc =... -
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... -
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... -
Studies of propene formation by gasoline cracking in steamed ZSM-5 by INS
Fluidised Catalytic Cracking (FCC) units (shown below) are one of the major conversion units in modern petrochemical refineries. ZSM-5 additives. These are used in FCC units to... -
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... -
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... -
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... -
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:... -
Chain exchange mechanism of complex coacervate core micelles
Complex coacervates have been studied for a long time for their medical applications and unusual physical-chemical properties: they are dense networks of poly-electrolytes, that... -
Mechanism of hydride-ion mobility in a novel oxide-hydride
This proposal requests 7 days of beamtime on the quasielastic neutron scattering spectrometer OSIRIS to investigate the mechanism of hydride ion mobility in the recently... -
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... -
Phase transitions in RbBi2Ti2NbO10
Ferroelectric materials, in which the polarization may be switched, are an important class of compounds due to their academic and technological relevance. The mechanisms that...
