Variable Temperature Study of Structural Transitions Occurring In Clusters of...
Catalysts lower energy costs of a wide range of important processes, from the production of oil and plastics to the preparation of drugs and paints, making these products... -
Mass-selective Neutron Spectroscopy of Molten FLiBe
We request time on VESUVIO to study the properties of FLiBe using mass-resolved neutron spectroscopy (MANSE). FLiBe is a mixture of BeF2 and LiF and its physical properties in... -
Muon radicals in the metastable phases of Sulphur
Following our investigation of alpha-orthorhombic sulphur, we will measure level crossing spectra of some other allotropes and phases, to find if the muon radical observed in... -
Structural Changes through the Semiconductor to Metal Transition in Cu2ZnGeSe4
We wish to collect powder neutron diffraction data as a function of temperature to investigate structural changes through a phase transition in the parent thermoelectric phase... -
Investigation of pseudo-condensation of supercritical H2 in nanoporous hydrog...
This proposal aims to use small angle neutron scattering for characterization of hydrogen adsorption (including the provision of a quantitative value for the absolute hydrogen... -

QENS studies of hydride ion diffusion in alkaline earth hydrides
We propose to study hydride ion diffusion in AEH2 (AE = Ca and Ba) using the QENS technique. We have recently demonstrated that the charge carrier in these materials are hydride... -
Oxide ion vacancy distribution in A site substituted defect pyrochlores.
Electrolytes based on pyrochlores such as Ln2M2O7 (M = Ti, Zr, Hf) have attracted attention due to their relative stability combined with relatively high ionic conductivity at... -
Copy of: Local magnetic order and the paramagnetic-parmagnetic transition in MnO
The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong... -
Investigation of the Li-intercalation mechanism for the perovskite Li0.18Sr0....
Our work on LSTN showed that it exhibits favourable electrochemical properties, i.e. rapid diffusion of lithium into the structure at low temperatures and the ability to... -
In-situ studies of alkaline earth nitride deuterides
Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical... -

Defect structure in W/Ln and Ta/Ln di-substituted bismuth oxide based solid e...
The stability regime of the oxide ion conductor delta-Bi2O3 is limited to a narrow temperature range just below its melting point. Substitution of Bi3+ by a variety of isovalent... -
Local structure in layered perovskite oxides - probing ion transport in fuel ...
Layered oxides are increasingly attractive as electrode materials in energy technology applications, such as fuel cells, electrolysers and permeation membranes. As the... -
In situ studies of mixed-phase oxygen transport membranes
The oxygen transport membrane is a system being developed by St Andrews in conjunction with industry, which at high temperatures will allow the selective migration of oxygen... -
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... -
Order-Disorder Transitions in Layered Tellurides
We have prepared a new series of layered tellurides Cr2-xInxGe2Te6, containing 2D ordered arrays of (Cr,In) cations and (Ge-Ge) pairs. Recent neutron measurements reveal indium... -
In-situ hydration and total scattering studies of Ba2In2-xMxO5 (M = Y and Ga)...
Motivated by the goal of improving the proton conduction in the brownmillerite Ba2In2O5 we are investigating the role of isovalent substitution at the indium sites. In... -
Oxygen mobility in the defect perovskite Sr3SbO5.5
We propose to use Polaris to record powder neutron diffraction data for the oxygen deficient double perovskite Sr3SbO5.5 as a function of temperature to establish the... -
Local structure and dynamics in metal-imidazolate frameworks
This proposal aims to study local structure and dynamics in two metal-organic frameworks (MOFs): namely, zinc imidazolate and cobalt imidazolate. Imidazole (IM) is a small, flat...
