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... -
New brownmillerite-based oxide ion conductors: Local structure and structure-...
Oxide ion conductors are key components in a number of technologically important applications. Our research programme on the development of new oxide ion conductors, using... -
Re-examination of PZT structures around a tricritical point
The mixture of lead titanate (PbTiO3) and lead zirconate (PbZrO3), known as PbZr1-xTixO3 (PZT), is commonly used in a wide range of applications (sensors, actuators, etc)... -
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... -
Reentrant Structural Transitions and Collapse of Charge and Orbital Orders in...
A-site ordered quadruple perovskites, AA3B4O12, show many interesting physical and chemical properties, for example, inter-site charge transfer and disproportionation, giant... -
Ammonia synthesis using lithium hydride-metal nitride composites: an in situ ...
The development of more active catalysts for the production of ammonia will have a worldwide impact on the energy cost of producing fertiliser. Composites of lithium hydride and... -
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. -
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... -
In-situ high-resolution study of the Pd-D2 system after passage over the ther...
Our previous HRPD experiment on the Pd-D2 system resolved the long-standing controversy over the occupation of T interstitial sites by D, showing that T sites are occupied owing... -
The Definitive Sodium Niobate Phase Diagram?
NaNbO3 has long been regarded as the 'most complex' perovskite known, with at least seven different phases reported as a function of T, at least two of which have evaded all... -
Spin reorientation transition in Ba2CrO2Cr2As2 - resubmission
This is an experiment to probe the magnetic ordering in Ba2CrO2Cr2As2 and compare the behaviour with the Sr analogue which shows a complex spin reorientation transition around...
