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 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... -
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... -
Understanding the decomposition of ammonia by lithium-calcium imide
Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data... -
In-situ studies of amides with ammonia
The aim of this proposal is to determine that materials that are present in the ammoniation of amides. -
Average structures of new functional oxides - HPRD
The proposal addresses the average structures of new lead-free ferroelectrics, low-temperature ionic conductors and mixed conductors which are candidate solid oxide fuel cell... -
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... -
Ba7MoNb4O20: Local structure analysis of a novel hexagonal electrolyte
Solid-state electrolyte materials are crucial for applications involving electrochemical conversion and storage, as these devices become increasingly important in the transition... -
Hydrogen from ammonia using lithium imide metal nitride composites
Light metal amides and imides are a new class of highly active ammonia decomposition catalysts. Indeed, composites of lithium imide and transition metal nitrides are likely to... -
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... -
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... -
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,... -
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 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...
