Clay barriers are routinely used in nuclear waste repositories to isolate radionuclides from the biosphere. Such barriers have to be carefully designed to remain effective for...

The ambient-pressure phase of ice is a well-known example of a molecular solid that exhibits negative volume thermal expansion below 60 K. In a recent study carried out on HRPD...

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

Phenol-water and phenol-ammonia clusters are useful model systems for understanding the types of proton-transfer interactions that occur during photosynthesis in plants and...

Phenol-water and phenol-ammonia clusters are useful model systems for understanding the types of proton-transfer interactions that occur during photosynthesis in plants and...

Clathrate hydrates (CHs) are ice structures in which water molecules (host) form cages through hydrogen bonds. The cages can accommodate various types of molecules (guests),...

The structure of liquids in confined geometries is of significant interest to many diverse areas, for instance chemical catalysis (liquid-phase reactions inside porous...

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...

An inelastic X-ray investigation on the collective inelastic dynamics of molten NaCl revealed the remarkable result that the acoustic-like dynamics is similar to the dispersion...

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,...

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...

In search for new materials with exotic electronic states, one often turns to strongly correlated materials. Ruthenium oxides attract attention as they exhibit intriguing...

Surfactant-silica self-assembly processes have been extensively studied since the discovery of M41S mesoporous materials in 1992. Mesoporous silicate films can be grown from...

Abnormally glycosylated IgA leads to IgA nephropathy, the most common cause of renal failure. IgG antibody represents one-third of new drugs currently in development, and its...

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...

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...

Ice and carbon exist in vast quantities in our Universe. In fact, they often coexist, and form interfaces in highly diverse settings and environments. These include, for...

This proposal will study the temperature dependence of the structure of a novel perovskite oxynitride SrTaO2N in order to establish how anion ordering impacts on the coupling of...

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...
