Magnetic and Structural Studies on Oxychalcogenides
In this proposal we request 3 days of beam time on HRPD to study the structures (both atomic and magnetic) of a variety of oxychalcogenide phases: La2O2Se2Fe2O, Ce2O2Se2Mn and... -
Roles of magnetic anisotropy and inter site exchange interactions in the temp...
NdMnO3 exhibits A-type antiferromagnetism with TN =73 K. At 15 K, Nd sublattice orders with a (0, -Fy, 0) type ferromagnetic arrangement. Mn spin reorientation from (Ax, Fy, 0)... -
Insight into the adsorbed water layer of hydration shells around iron oxide n...
With this proposal we want to study the (deuterated) hydration shell of facetted iron oxide nanoparticles (IONPs). IONPwater interfaces are of great importance for biomedical... -
Voltage-induced swelling and collapse of weak polyelectrolyte brushes
The voltage-induced actuation of a weak polyelectrolyte brush is an example of an ultrathin, remotely controlled responsive surface coating. We propose a continuation of... -
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... -
Persistent geometrical frustration in the distorted spinel lattice
The corner-shared network of tetrahedra is the most well-known lattice exhibiting geometrical frustation of AFM exchanges under cubic symmetry. Even when the lattice symmetry is... -
Combined in-situ structural and hydrogen desorption/absorption studies of hyd...
The Li?N?H hydrogen storage system is one of the most promising candidates for hydrogen storage in vehicular applications and the addition of halide ions significantly increases... -
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... -

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... -
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... -
