IN-SITU NEUTRON DIFFRACTION STUDIES OF METAL-HYDRIDE HYDROGEN STORAGE MATERIALS
Hydrogen storage is considered to be one of the principal technological barriers in the transition towards a hydrogen-based economy. In this proposal, we plan to look at the key... -
Investigation of the hydrogen-bonded zero area expansion material 4-chloroimi...
We will investigate the structure of 4-chloroimidazole a material which undergoes extreme anisotropic thermal expansion. This is believed from our initial X-ray data to be due... -
Investigation of the impact of mechanical twinning on the thermal expansion b...
We request three days of beam-time on POLARIS to investigate the influence of thermally-induced twinning on the thermal expansion behaviour of polycrystalline calcite.... -
In-situ characterisation of mixed steel powders during simulated powder proce...
It is proposed that the lattice parameter change at high temperature is measured for a mix of 316L and SA508 grade 3 steel powders, by means of neutron diffraction in High... -
In situ studies on the decomposition of NaNH2 and possible formation of Na2NH.
Group 1 amides of general formula MNH2 are some of the most promising materials for hydrogen storage applications due to their relatively low temperatures of hydrogen evolution... -
Structural distortions and partial order in the selenate and chromate analogu...
The mineral mirabilite (di-sodium sulfate decahydrate) has been extensively studied by X-ray and neutron powder and single-crystal diffraction methods. The structure contains an... -
The phase stability of alpha-glycine at high pressure
Though the beta and gamma forms of the simplest amino acid, glycine, yield a variety of different phases on application of pressure, Raman data suggest that the most common... -
In situ studies on hydride diffusion and exchange in alkaline earth hydrides ...
Thermogravimetric analysis on alkaline earth hydrides in St Andrews has revealed a remarkably fast exchange of deuterium and hydrogen by alkaline earth hydrides at relatively... -
Probing of hydride phase formation of Pd nanoclusters embedded in the NH2-UiO...
With this proposal, we would like to investigate a material that could be used as a catalyst for hydrogenation reactions. A catalyst acts to increase the rate of a reaction by... -
In situ diffraction studies of cathode materials for Li ion batteries
Li-ion batteries are interesting because they offer high power and, as a consequence, they are preferred to aqueous-based batteries for traction applications e.g. hybrid... -
Structures and thermal expansivity of recovered phases of urea II & III
Urea is a prototypical hydrogen-bonded small molecule that has stimulated considerable fundamental research into its structure, elastic properties and polymorphism. Amongst the... -
Thermal expansion of recovered high-pressure ice polymorphs
The ambient-pressure phase of ice is a well-known example of a molecular solid that exhibits negative volume thermal expansion below 60 K. In a recent study carried out on HRPD... -
The Interaction of Ammonia with Binary and Ternary Nitrides
We request 2 days on GEM in conjunction with the IGAn apparatus to investigate the formation of lithium amide (LiNH2) from the interaction of Li3N with ammonia (ND3), and the... -

Dirac Point and Topological Triplon Bands in the Shastry-Sutherland Material ...
SrCu$_2$(BO$_3$)$_2$ (SCBO) is a very much studied quantum magnet that is most well known for its ground state of coupled singlets and multiple magnetization plateaux. Recently,... -
Structural and magnetic neutron diffraction study of a novel frustrated syste...
Every new triangular lattice (TL) antiferromagnet attracts considerable attention since they usually display rich physics due to the inherent frustration and degenerate ground... -
Determination of Exact Structural Symmetries in LaFeAs1-xPxO
LaFeAs1-xPxO has recently been proposed to display unusual properties as a function of P doping with two distinct superconducting (SC) domes separated by a possible AFM phase as... -
