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...

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...

We propose a high-pressure neutron powder diffraction study of three halogen-bonded complexes, namely trimethylamine:ICl, 1,4-dioxane:(IBr)2 and pyridine:IBr. These are some of...

Olivines - in particular the solid-solution between forsterite (Mg2SiO4) and fayalite (Fe2SiO4) - are important rock-forming minerals on Earth, also occurring in meteorites and...

Transition metal oxynitride perovskites are an emerging class of functional materials. However, their oxide/nitride ordering principles were unclear until a recent study of the...

Ammonia is an extremely important industrial chemical and a fundamental canonical hydrogen-bonded solid. An accurate and precise crystal structure for solid ammonia at ambient...

Bi0.7La0.3FeO3 has received extensive attention in the past years, since this compound exhibits simultaneously ferroelectricity and ferromagnetism at room temperature. Despite...

As part of our research into novel cathodes for sodium ion batteries we request beamtime to study the structures of a series of bimetallic sulphates. Sodium transition metal...

We propose to study the effect of pressure and temperature on the crystal structure and the elastic properties of lead selenide, an important material for conversion of waste...

KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling...

The aim of this experiment is to complete the understanding of the complex nature of the structural and magnetic interactions in the La0.7Sr0.3Mn1-xFexO3 series of materials in...

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...

4 days are requested on HRPD to collect Neutron Diffraction (ND) on a carefully designed series of (Na1/2Bi1/2)TiO3-based perovskites (NBT) that exhibit a switch in electrical...

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...

We request two days on Engin-X to carry out commissioning tests on a pair of new piston-cylinder cells and their associated hydraulic press. Although intended primarily for use...

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...

Recently we have developed a family of fast Li-conducting garnets via doping with Li7-3xGaxLa3Zr2O12 (0 ≤ x ≤ 0.5) system. The measured bulk conductivities at room...
