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...

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...

Pyrolysis is considered as a sustainable way to generate energy from bio-oil, however, biochar – a solid residue by-product– is inevitably produced in the production line. We...

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...

In this proposal we request 3 days of beam time on HRPD to study the structures (both atomic and magnetic) of a variety of oxychalcogenide phases: La2O2Se2Fe2O, Ce2O2Se2Mn and...

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...

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...

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...

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...

We request 2 days on GEM in conjunction with the IGAn apparatus to investigate the formation of lithium amide (LiNH2) from the interaction of Li3N with ammonia (ND3), and the...

In this proposal we request 4 days of beamtime on GEM to study four new transition metal oxyselenide materials. Two new layered oxyselenides, La2O2Se2Mn and La2O2Se2Fe have been...

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...

Atmospheric climate change is strongly influenced by clouds and the oxidative processing of pollutants in clouds affects droplet size and reflectivity of the planet. Clouds...

Sr3Ru2O7 is a layered Ruddlesden-Popper perovskite which displays intriguing behaviour at low temperatures and high magnetic field. It can be tuned close to a quantum critical...

NaAlH4 has been a model system for metal hydride hydrogen storage materials since the reaction was identified to be reversible. The decomposition pathway has been described by a...

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...
