Materials with incommensurate structures often show exotic properties (such as charge density waves). The development of reliable and efficient refinement techniques for such...

This proposal is part of our research programme on spin and orbital order in frustrated systems. AgNiO2 has a layered crystal structure with Jahn-Teller active Ni3+ ions forming...

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...

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...

We have constructed a novel microwave frequency resonator that can sit within the GEM and POLARIS diffractometers and will allow us to simultaneously collect diffraction and...

We seek to develop new MOFs for sensing and removal of toxic gases (e.g., SO2) and request 4 days on POLARIS to study the structural binding details and dielectric data...

Inexpensive light-metal amides are among the most highly active and effective ammonia decomposition catalysts at modest temperatures and are likely to surpass the performance of...

Heavy alkaline earth nitride hydrides (AE2NH, with AE = Ca and Ba) are of interest due to their potential suitability as electrolyte materials in a variety of electrochemical...

We ask for 3 days on GEM to study in-situ the decomposition of the Na-substituted LiNH2 phases, Li1-xNaxND2, LiNa2(ND2)3, Li3Na(ND2)4 and their reactions with LiD. LiNH2 is the...

Ammonia has been proposed as a high density chemical energy-storage media, which can be safely and reversible stored within low cost saline halides. Here we propose to extend...

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...

This proposal seeks to study three systems associated with heat-storage applications using in situ neutron powder diffraction. The first experiment will focus on a sample of...

The Li?N?H hydrogen storage system is one of the most promising candidates for hydrogen storage in vehicular applications and the addition of halide ions significantly increases...

We request 3 days beam time on POLARIS for the in-situ study of the crystalline phase composition of iron, manganese and ruthenium catalysts for ammonia decomposition. These...

We request 3 days on POLARIS to study the detailed crystal structure of a sodium battery cathode material that is currently under consideration for use in commercial sodium...

This proposal seeks 2 days on POLARIS in order to fully complete the commissioning of a large volume in-situ reaction cell for studying hydrothermal chemical syntheses in...

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...

We seek to develop new materials for sensing and removal of toxic gases (esp., SO2) and request 2 days on POLARIS to study the structural binding details and dielectric data...

It is generally accepted that austenitic steels (fcc) show no ferromagnetic signature. However, thermomagnetic measurements suggest an unexpected ferromagnetic transition (Tc =...

This proposal aims to study the potential for neutron diffraction to offer spatially-, chemically-, and temporally-resolved information on a dynamic system, in this case the...
