Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Barocaloric materials...

LixCoO2 is used extensively in portable batteries in laptops and mobile phones, but the scarcity of Li means that alternative materials are required. Structurally related...

Using deep inelastic neutron scattering, we plan to investigate chemical short range order on a quantitative level in liquid alloys and its correlation with the long range mass...

Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al...

A new metamagnetic material CoSr2Nd1.1Ce0.9CuO9±d has been synthesised. At 2 K the metamagnetic transition occurs at a field of 0.1 T. We propose to measure the field dependence...

Methylammonium lead iodide has recently been recognised as an excellent photovoltaic material, with energy conversion efficient of up to 15% with the prospect of gaining higher...

Oxides with tetragonal tungsten bronze (TTB) structures are an important class of ferroelectrics with properties relevant for several technological applications. The...

Quite recently, the high thermoelectric performance has been reported in the MgAgSb-based half Heusler alloys. The ZT values close to 1 at room temperature with a maximum of ZT...

All solid-state sodium ion batteries are potential low-cost alternatives to lithium ion batteries, especially for static and large-scale energy storage systems. The shift from...

Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold...

We propose to study two aspects of the hydrogen dynamics in complex hydrides:First: The structural transitions in borohydrides are believed to be connected with an increase in...

LiBH4, is an ionic solid, consisting of Li+ and BH4- ions. It undergoes a structural phase transition at 383K. Within the HT phase, the BH4-units undergo rapid re-orientations,...

LaCa2Fe2GaO8 adopts a 3-layer cation-ordered structure. Magnetisation data collected from this phase exhibit two high-temperature anomalies consistent with the onset of...

Cerium-based Kondo lattice compounds have received great attention, owing mostly to the variety of exotic ground states that they exhibit (e.g., unconventional...

Organic ferroelectrics are in the focus of current research because their potential applications as a material to address global challenges. These lightweight, flexible and...

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...

Strong orbital mixing resulting from local distortions in the crystal field can mix higher energy orbital states with the ground state. We propose to characterise this mixing in...

High-entropy alloys (HEAs) typically contain four or more principle elements in equimolar amounts. We have recently discovered the first bcc HEA-based hydride with reversible...

In the vicinity of x ~ 0.75, LixCoO2 has potential as a thermoelectric, since it has a high Seebeck coefficient and metallic conductivity. We have performed the first successful...

The properties of methane ammonia water mixtures are crucial for models of how the outer planets evolved and yet have not been much studied. This proposal is for beamtime to...
