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,... -
Copy of: Local magnetic order and the paramagnetic-parmagnetic transition in MnO
The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong... -
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... -
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... -
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... -
Simultaneous Conductivity-Diffraction Studies of Halide Superionics
We request 5 days beamtime on the Polaris diffractometer to perform simultaneous ionic conductivity and neutron powder diffraction measurements of five superionic binary... -
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... -
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...
