This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well...

In a proof-of-concept beamtime award (RB1220486) we studied the process of platinum-catalysed benzene hydrogenation in the pores of MCM-41 using standard neutron diffraction...

Previous studies have pointed to a heavy-electron state in CePtSi with a strongly enhanced electronic specific heat. We have explored the heat capacity, susceptibility and...

Mixture of water and dimethylsulfoxide (DMSO) are useful as preservative liquids for the storage of living cells at very low temperatures, such that they can be revived and used...

At room temperature the ternary stannide CeRuSn crystallizes with a super structure of the monoclinic CeCoAl-type structure. Charge ordering produces a doubling of the unit cell...

Green dioptase is a naturally occurring mineral, that has a deep green colour, similar to that of an emerald, and with a chemical formula of CuSiO3.H2O. The Cu lies in quasi-1D...

The proposed experiment is addressed to use the MARI spectrometer to study the thermal denaturation process of the psychrophile enzyme alpha-amylase in presence of bioprotectant...

Barocaloric materials, in which a large isothermal entropy change is associated with a pressure-induced phase transition, offer an alternative to vapour-compression techniques...

We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a...

The hardening process of moulding sands on quartz matrices bound by polymer binders containing carboxyl and hydroxyl groups can be carried out by using physical agents...

A controlled investigation of light-induced changes in hybrid perovskites is required to achieve stable operation of tandem solar cells and colour-tuneable light-emitting...

High pressure is a powerful thermodynamic tool, like temperature, to vary the properties and structure of materials. X-ray and neutron diffraction can be used to measure certain...

Magnetic nanoparticles are currently being investigated comprehensively. Our ball-milled TbCu2 nanoparticles show a core-shell structure in which the core orders...

We studied a new metamagnetic heavy-fermion (HF) compound YbRh3 Si7, synthesized for the first time. This is the first HF compound in the ScRh3Si7 family, for which the only...

This experiment will measure the microstructure of Amorphous Solid Water (ASW), a porous material that can be formed by vapour-depositing water onto a cold plate, an excellent...

We will determine the atomic and magnetic structure of two polymorphs of manganese cyanide, Mn(CN)2, which exhibit negative thermal expansion (NTE). The two forms are related;...

Methylammonium lead iodide is currently one of the most promising materials for solar energy applications, with light-conversion efficiencies exceeding 20%. Although insightful,...

Acetylene is produced in great abundance in the solar system wherever carbonaceous solids are exposed to energetic radiation. It has been the subject of several studies,...

There are great energy costs associated with the separation of the light olefins (ethylene and propylene) from mixed hydrocarbon gas feeds. These olefins (obtained from natural...

Novel cathode materials for rechargeable batteries have been under intense investigation since high cost and toxicity of current Li-ion batteries. We propose to study the...
