Local Structure within Fluorite-Pyrochlore Solid Solutions
This proposal requests 6 days beamtime on the Polaris diffractometer to study the nature of the local structure within two systems which have been reported to show a solid... -
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... -
Local structure within Li+ depleted LiFePO4
Lithium iron phosphate is a commonly used cathode material in Li-ion batteries. The material exhibits a two phase system on lithiation and delithiation with narrow solid... -
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... -

Local structure of liquid gallium-iodine and gallium-indium
Liquid metal alloys, with liquidus temperatures close to room temperature, are a rapidly developing research area with novel applications in renewable energy, catalysis,... -
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... -
QENS Investigation of Proton Conduction Mechanism in Spark-Plasma-Sintered Pr...
Fuel cells exhibit high-energy efficiency and the only release is clean water when used with hydrogen. Proton ceramic fuel cells (PCFC) are from special interest because proton... -
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... -
Towards the development of carbonitrides as novel two-stage regenerable reage...
We are examining a number of cobalt-molybdenum carbonitrides as possible catalysts for reactions that produce nitrogen-containing organic molecules. There is good evidence that... -
In-situ hydration and total scattering studies of Ba2In2-xMxO5 (M = Y and Ga)...
Motivated by the goal of improving the proton conduction in the brownmillerite Ba2In2O5 we are investigating the role of isovalent substitution at the indium sites. In... -
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... -
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... -
In search of origin of metal-insulator transition in honeycomb structure Li2RuO3
Recently we have carried out inelastic neutron scattering measurements on Li2RuO3 to understand the nature of the phase transition at 550K. We have seen a clear inelastic...
