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...

Perovskite manganates with the general formula L1-xAxMnO3 (e.g. L=La, Pr , Nd and A=Ca and Sr) have attracted significant interest as a result of their unusual transport and...

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...

TOF-Neutron Diffraction experiments conducted on significant archaeological findings from the pre-roman Ligurian settlement of Guardamonte (Monte Vallassa) have shown unusual...

Organic ferroelectrics are in the focus of current research because their potential applications as a material to address global challenges. These lightweight, flexible 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...

The Ruddlesden-Popper (RP) compounds An+1BnO3n+1 exhibit a broad range of technologically interesting properties such as high-Tc superconductivity, colossal magnetoresistance,...

This beamtime request is part of a long term project based on the liquids diffractometer SANDALS and aimed at developing the use of Paris-Edinburgh press for liquids and in...

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...

Recent published studies have identified a stable solid form of carbonic acid at high pressure. This proposal is for beamtime to collect the data to solve its crystal structure.

Cu2ZnSnS4 (CZTS) is a solar cell material of great interest. However the material when fabricated, although of high symmetry, contains substantial defect concentration and a...

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...

Research on positive insertion electrodes for high performance batteries has seen immense interest in fluoride containing compounds, since higher operating potentials can be...

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...

Modulation occurs when there is ordering on two (or more) length scales. When the ratio of these is an integer, the modulation is said to be commensurate, i.e. one ordering is...

We have recently discovered a pressure-induced quantum phase transition (QPT) at 4.3 kbar in the gapped quantum magnet piperazinium hexachlorodicuprate (PHCC) by means 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...

We propose to measure the structural relaxation in this prototype glass former. The structural ralaxation time will be obtained at the structure factor maximum. We suppose that...
