We request 1 day of beam-time on POLARIS to collect Neutron Diffraction (ND) data on the Sillenite Bi12SiO20 (gamma-Bi2O3) that we have recently discovered to exhibit a...

Abstract. In experiments at LLB and ILL we have measured low-resolution INS spectra and elastic scans for H2O- and D2O-hydrated samples of a 15-residue oligopeptide between 30...

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...

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...

Structural studies of water have been made for a wide range of states but little work has been made for ¿stretched water¿, i.e. under negative pressure. This state may be...

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...

It is a well established fact that several molecular liquids experiences a series of thermal anomalies as measured by microscopic and macroscopic techniques. A remarkable case...

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...

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...

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...

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,...

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...

Pb-Li alloy (Li 15.7-16.7at.%) is a candidate as tritium breeding blanket material for fusion reactors. Despite the extensive work reported in literature, the values of the...

Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric...

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...

Experiments performed in our laboratory indicate that maleic acid undergoes an unexpected structural change when subject to high pressure and temperature conditions. For these...

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...

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...

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...
