The quest for fully hydrogen-ordered ice XIV
Water ice displays a remarkably complex phase diagram containing pairs of hydrogen-ordered / disordered phases. Ice XII is a hydrogen-disordered phase and ice XIV is its... -
Magnon dispersion in the polar ferrimagnet BaCaFe4O7
Polar or non-centrosymmetric ferri(-o)magnets offer a plethora of potential technological devices;the inherent magnetoelectric effect can underpin both pyroelectric or... -
Non-magnetic impurities in a strong-leg spin ladder
Th S = ½ AF spin ladder is one of the most important models in quantum magnetism. While its properties throughout the (H,T)-phase diagram may be considered to be well understood... -
In-situ Battery Discharge Studies of Thermal Batteries using Transition Metal...
Thermal batteries find use in applications such as emergency power systems and ejector seats in aircraft. They operate at elevated temperatures of around 400-500 °C, where the... -
Thermoelastic Properties of Thermoelectric PbSe I HRPD
We propose to study the effect of pressure and temperature on the crystal structure and the elastic properties of lead selenide, an important material for conversion of waste... -

Structural and magnetic orders in Ga-V oxide spinels
In certain materials, notably with the spinel structure, orbital ordering can result in the formation of a ground state with electrons delocalising between small numbers of... -
Characterization of the texture properties of Euro coins as a function of min...
This work intends to see if a diffraction technique is able to distinguish between coins minted in different places. All the physical properties of euro coins were restricted by... -
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 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... -
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... -
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...
