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...

Magnetic cooling has recently become the focus of cooling system technology as it boasts important advantages in terms of power consumption and for the environment e.g. not...

[BiZn2/3NbO3]x-[BaTiO3]1-x for x up to roughly 0.2, known as BZN-BT is a complex made from one of the most studied materials in the world, BaTiO3 (BT), doped with Bismuth Zinc...

In certain materials, notably with the spinel structure, orbital ordering can result in the formation of a ground state with electrons delocalising between small numbers of...

We request NR beam time on SURF to study the impact of multivalent counterions on the surface adsorption of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /...

CaSiO3 perovskite is the third most abundant mineral in the Earth's lower mantle (below 670 km). It also occurs as a major phase at lower pressures and temperatures in...

In order to tackle emissions targets for CO2, there is increasing pressure to replace fossil fuels with renewable fuels. Biodiesel is one such renewable transportation fuel that...

LiCoMnO4 is a spinel material of great interest for possible applications in the next generation of lithium-ion batteries. LiCoMnO4 exhibits electrochemical activity at 5 volts,...

Mixtures of methanol with water and ammonia dominate the chemistry of cometary bodies, leftovers of the building blocks of the outer planets. We have previously determined the...

The term cononsolvency has been used to describe a situation in which a polymer is less soluble in a mixture of two cosolvents than it is in either one of the pure solvents. If...

Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped...

Nanoscale magnetic skyrmions are swirl-like magnetisation entities that satisfy topological quantisation conditions. They can therefore not be easily unwound into another...

Neutron reflection has been successfully used to measure the conformation of proteins adsorbed at the oil/water interface. However, in several such experiments, hexadecane has...

Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crysta. There are outstanding...

The "magnetocaloric effect" (MCE) is based on the entropy difference encountered when themagnetic state of a material is changed and it can be used for refrigeration. However,...

Mn12, with an anisotropy barrier close to 65 K, has been for 20 years a prototype nanomagnet, but in spite of a number of investigations the actual link between the value of the...

The functionality of biological membranes is closely tied to their structural behavior. To understand this behavior we propose to study the conformality of artificial lipid...

This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we apply for a...

It is the aim of the current proposal to examine in detail the magnetic structure of LaCo0.75Mn0.25O3 at low temperature, which should provide insight into the nature of the...

This proposal aims to investigate the effect of magnetic impurities on the ALC resonance amplitude of an organic semiconductor (RRa-P3HT), to determine whether the effect can be...
