This proposal seeks 2 days on POLARIS in order to study hydrothermal chemical syntheses of yttrium aluminium garnet, Y3Al5O12 (YAG) in supercritical water using the...

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...

The detection of hydrogen content in bulk media is a challenging task. Several techniques aiming at measuring the amount of hydrogen require disruption or erosion of the sample....

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...

Thermoelectric devices are capable of converting thermal energy directly into electrical energy. Large-scale applications of the technology requires materials that are composed...

Ammonia borane (AB) is arguably the most promising hydrogen storage material for use in clean, green fuel applications. Simple heating of AB produces hydrogen that can be used...

Cubic cadmium(II) cyanide shows the most pronounced isotropic NTE effect known, with behaviour more than twice as extreme as that of better known materials such as ZrW2O8. This...

We propose to study the magnetic fluctuations of the unconventional superconductor Sr2RuO4 in the superconducting state extending our previous experiments on a cold triple-axis...

Whilst rechargeable batteries continue to take over the consumer electronics market, they are unsuitable to replace specific battery technologies, such as the thermal battery,...

The objectives of this proposal is to seek 2 days on POLARIS in order to test and complete a full commissioning of the latest design of our prototype in-situ reaction cell for...

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...

In a series of in situ neutron diffraction measurements from deuterium up-take in Li3N, the present authors have identified a novel non-stoichiometric 'quasi-imide' 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...

SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of...

The aim of this proposal is to study the condensation transitions of polar gas molecules in nanoporous flexible materials by means of wide Q-range neutron diffraction. An...

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...

The objective of the proposed experiment is to develop an understanding of the Li/Ni/Mn ordering in a commercially relevant lithium ion battery positive electrode,...
