An uncommon oxygen absorption/desorption behavior for cobalt oxide YBaCo4O7+d was found[Karppinen et al. Chem Mater 18 2006 490]. Y114 absorbs and desorbs oxygen up to d = 1.5...

Al2SiO5 forms three naturally-occurring polymorphs, kyanite, andalusite and sillimanite. These minerals are produced by varying degrees of metamorphism of sedimentary rocks, the...

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...

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

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...

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...

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...

We propose to use the HRPD to establish the sequence of structures, and the nature of the transitions between these, in two complex manganites Sr0.5Pr0.5MnO3 and...

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...

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...

The most important scientific problems to solve for the future is how to efficiently convert and store clean energy. To realize all-solid-state devices and high-performance...

Metallic materials that exhibit negligible thermal expansion or zero thermal expansion (ZTE) have great merit in practical applications. However these materials are very rare...

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 recent years there has been a resurgence in research dedicated to ferroelectric materials primarily due to the combination of the requirement for Pb-free replacements for...

Pb-based materials such as PbZrxTi1-xO3 (PZT) are widely used as transducers, actuators and sensors in a range of modern technologies due to their excellent piezoelectric 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...

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...

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 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...
