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...

The sequence of structural phase transitions that occur in distorted ABO3 perovskites as a function of temperature is of intrinsic interest for better understanding of the...

The aim of the experiment is to monitor the temporal evolution of gamma prime precipitates in three polycrystalline nickel base superalloys using Sans2D. This instrument is...

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...

Recently [RB 900007], we have demonstrated that it is possible to determine the detailed site-by-site behaviour of hydrogen during in-situ absorption and desorption in metal...

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...

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...

We propose to develop the means to measure the orientations, phases and strains of individual crystal grains within a polycrystal using neutrons. Such measurements have...

This proposal requests 7 days of beamtime on the quasielastic neutron scattering spectrometer OSIRIS to investigate the mechanism of hydride ion mobility in the recently...

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...

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...

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...
