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 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...

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...

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...

Diamonds provide our only direct samples of the very deep Earth and understanding their origin is consequently of great interest to Earth Scientists. The origin of diamonds can...

The current proposal seeks to establish the origin of t non-perovskite-like peak splitting observed in HRPD data for NaTaO3. It is our hypothesis that this is a result of the...

The current proposal seeks to establish the origin of t non-perovskite-like peak splitting observed in HRPD data for NaTaO3. It is our hypothesis that this is a result of the...

Light-metal hydride and amide systems are currently among the most promising materials for reversible hydrogen storage. In this proposal, we ask for 3 days on POLARIS or GEM to...

In this work, we will investigate the structures (crystallographic and magnetic) of Mn5VO8 and a range of Fe containing perovskite oxide fluorides. In terms of the former, this...

On exposure to ammonia, LiBD4 and Mg(BD4)2 form the respective ammoniates, Li(11)BD4(ND3)n and Mg((11)BD4)2(ND3)6. We have identified the decomposition temperatures, kinetics...

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...

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...

SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase...

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...

Many of the devices currently used for energy storage (e.g., batteries, solar cells) use liquid electrolytes that are known to pose a serious fire and safety risk. However, the...

Among light metal amide-imide catalysts for ammonia decomposition, lithium-calcium imide is the most promising candidate for practical application. Ex situ diffraction data...
