Total scattering from multiferroic bismuth ferrite at high temperatures
Bismuth ferrite (BiFeO3) is the archetypal multiferroic material and as such has been copiously studied using a wide variety of techniques. Despite this, new structural and... -
In-situ reaction of lithium amide or imide with manganese(IV) oxide
We request 3 days beam time on POLARIS for in-situ powder diffraction studies of the reactions of lithium amide or lithium imide with manganese(IV) oxide under flowing argon or... -
Formation and ammonia decomposition behaviour of lithium nitride hydride
Ammonia is seen as a key part of the transition to a sustainable energy economy, but needs decomposition catalysts to release its stored hydrogen. Lithium nitride-hydride... -
In-Situ Studies of Alternative Mobile-Ions for High-Temperature Thermal Batte...
Whilst rechargeable batteries continue to take over the consumer electronics market, they are unsuitable to replace specific battery technologies, such as the thermal battery,... -
Towards the development of lithium manganese nitride as novel two stage regen...
In the last decades the production and consumption of reactive nitrogen increased exponentially due to the extensive utilisation of nitrogen containing compounds as fertilizers... -
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... -
Phase Transitions and Orbital Ordering in SrRu1-xCuxO3.
This proposal seeks to establish the importance of orbital ordering on the stability of the tetragonal phase in Cu doped SrRiuO3. Orbital ordering is believed to be a... -
In-situ studies of thermal electrochemical cells utilising transition metal s...
Thermal batteries are used in applications were high reliability is a key requirement. They can be stored for decades and activated in less than a second. Most contemporary... -

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... -
Spin orientation in natural nanoscale intergrowths and the origin of giant ex...
The orientation of spins in a natural sample of Ti-bearing hematite (Fe2O3) has been measured previously from 2-300K using neutron powder diffraction. It was shown that spins... -
In-situ neutron powder diffraction study of the synthesis of Half-Heusler the...
XNiSn (X = Ti, Zr, Hf) Half-Heusler materials are potential candidates for application in thermoelectric waste heat recovery. The aim of the experiment is to follow the... -
Structural Disorder in the Quantum Spin Liquid Candidate YbMgGaO4
Quantum spin liquids are novel magnetic states in which quantum entanglement suppresses conventional magnetic order. Understanding the effects that stabilise such states is 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...
