Below 80 K ordinary water ice (ice Ih) undergoes a phase transition in which the randomly oriented molecules in the crystal adopt an ordered orientation. This ordered form of...

We propose to measure the one- and multi-magnon excitations in the first realization of a S=1/2 quantum spin ladder in the strong-leg regime. Our material, DIMPY, has very well...

The reaction of methanol to form hydrocarbons over zeolite catalysts is an important option for conversion of natural gas or coal to liquid fuels. We have shown previously via...

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,...

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...

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...

Here the use of the IGAN system for in-situ TGA and neutron diffraction is proposed in order to study the de-hydration of four proton conducting materials. The selected...

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...

This proposal seeks to test a new battery designed to allow in situ neutron diffraction measurements of lithium ion battery electrodes under charge and discharge. We have...

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...

SrCu$_2$(BO$_3$)$_2$ (SCBO) is a very much studied quantum magnet that is most well known for its ground state of coupled singlets and multiple magnetization plateaux. Recently,...

Recent studies in our laboratory have shown that a range of A-site deficient perovskite oxides, with carefully tuned chemical compositions, exhibit excellent properties when...

We wish to develop a rational understanding of the mechanisms underlying the way water soluble polymer brushes - in particular those of polyethylene oxide/polyethylene glycol -...

Recent studies in our laboratory have shown that a range of A-site deficient perovskite oxides, with carefully tuned chemical compositions, exhibit excellent properties when...

Organic molecular crystal structures have densities that are typically in the range 1.2-1.4 gcm-3 although these can be increased, in general, to ca. 2.0 GPa through application...

The recently reported double perovskite analogue imidazolium potassium iron(III) cyanide is noteworthy for two reasons. First, the order-disorder phase transitions, in which the...

Thermal batteries are used in applications were high reliability is a key requirement. They can be stored for decades and activated in less than a second. Most contemporary...
