For energy storage applications, high energy density is an important material characteristic when searching for new types of suitable materials. LiNi0.5Mn1.5O4 (LNMO) is an...

The estimated number of contact lens wearers worldwide exceeds 140 million people: contact lenses are indeed commonly used for corrective, therapeutic and esthetics purposes....

We have recently carried out an inelastic neutron scattering experiment at LET in order to investigate the excitations in the quantum spin ice Yb2Ti2O7. The single crystal...

Several distinct families of layered perovskites have been shown experimentally to display ferroelectricity. The most recent of these is the Dion-Jacobson (DJ) family, typified...

Ionic conductivity is a property where a material is able to conduct electricity through the movement of ions. Oxide ion conductors can be used in solid oxide fuel cells, which...

Water ice displays a remarkably complex phase diagram containing pairs of hydrogen-ordered / disordered phases. Ice XII is a hydrogen-disordered phase and ice XIV is its...

Thermal batteries find use in applications such as emergency power systems and ejector seats in aircraft. They operate at elevated temperatures of around 400-500 °C, where the...

Hydrogen is an efficient energy carrier that can be produced from renewable sources and stored in alloys in solid-state for long period enabling the transition towards CO2-free...

The Earth¿s climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects cloud droplet size and optical properties, important climatic...

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...

Projected climate change is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and reflectivity, important climatic effects....

It is proposed that the lattice parameter change at high temperature is measured for a mix of 316L and SA508 grade 3 steel powders, by means of neutron diffraction in High...

Group 1 amides of general formula MNH2 are some of the most promising materials for hydrogen storage applications due to their relatively low temperatures of hydrogen evolution...

Thermogravimetric analysis on alkaline earth hydrides in St Andrews has revealed a remarkably fast exchange of deuterium and hydrogen by alkaline earth hydrides at relatively...

Li-ion batteries are interesting because they offer high power and, as a consequence, they are preferred to aqueous-based batteries for traction applications e.g. hybrid...

With appropriate storage materials, ammonia has great potential as a fuel. We propose to use a novel piece of equipment, which combines microwave and neutron diffraction...

XNiSn (X = Ti, Zr, Hf) Half-Heusler materials are potential candidates for application in thermoelectric waste heat recovery. The aim of the experiment is to follow the...

Bio-responsive polymers hold great promise as delivery vehicles for drugs, peptides and proteins as their chemistry can be tuned to effect a change in physico-chemical...

Increasing global population, global warming and depletion of fossil fuels have resulted in a growing need for better energy storage. Lithium-ion batteries are promising devices...

We intend to study the phase behaviour of 2 cationic polythiophenes, P3MAHT and P3ImiHT, in the presence of the perfluorinated surfactant potassium...
