Scandium fluoride has recently been identified as a very simple example of a material showing negative thermal expansion over a wide range of temperatures. In particular, it...

Lithium-ion batteries are of great interest for automotive applications but are expensive. Sodium is much more abundant and hence cheaper so for e.g. storing energy from...

The recently reported double perovskite analogue imidazolium potassium iron(III) cyanide is noteworthy for two reasons. First, the order-disorder phase transitions, in which the...

Recent single crystal work on α-CoV2O6 has found a significant enhancement of the nuclear Bragg peaks on entering the low temperature antiferromagnetic states. This...

The proposed experiment aims to study the dynamics of hydrated lysozyme in presence of trehalose, glycerol and trehalose/glycerol mixtures at different relative concentration in...

The search for new porous materials is increasingly be driven by socio-economic pressure to diversify our energy supply and minimize environmental impact. Carbon-based...

Heavy fermion systems situated close to a quantum critical point present very rich physics due to the dominant Kondo interactions. Our investigations on the Kondo lattice heavy...

The metal-organic framework perovskite analogue guanadinium copper(II) formate has achieved considerable recent attention for its multiferroic properties and consequent...

Under confinement in porous media, helium-4 excitations develop a complicate behaviour and, in addition to a bulk-like spectrum, a second branch emerges due to helium-4 atoms in...

We propose to measure the high energy magnon spectrum of Bi2Fe4O9 in order to finalize a spin wave model and to classify this compound within the theoretical phase diagram of...

Cold neutrons are widely used in different fields of research such as the study of the structure and dynamics of solids and liquids, the investigation of magnetic materials,...

Pb2FeMO6 phases are of interest as potential multiferroics. We have prepared a new non-centrosymmetric pyrochlore-derived structure containing anion vacancy ordering...

Non-coplanar magnetic orders in metallic helimagnets have been of great interest since the discovery of a vortex-like spin-swirling object called "skyrmion" and the resulting...

Despite the importance of the LiFeO2 phases as cathode materials in lithium ion batteries, little is known about their crystal structures. In the frame of our research project...

Thermoelectricity enables the conversion of waste heat into useful power, and it is becoming increasingly important for power recovery applications at high temperature, where...

In this proposal we aim to study the low temperature uptake and dynamics of hydrogen in the interlayer region of partially hydrated pillared clays. There are linked dual...

A-site-ordered perovskite oxides with formula AA'3B4O12 have a rich variety of physical and chemical properties. Most have Jahn-Teller active Cu2+ or Mn3+ at the square-planar...

The intermetallic Mo3Sb7 compound exhibits superconductivity at Tc=2 K and exhibits interesting physical properties in the magnetic susceptibility, electrical resistivity and...

It is well known that water is the medium in which the overwhelming majority of biological processes take place. In cell membranes water molecules are thought to be essential to...

This proposal aims to investigate the dynamics of the melting transition in H2O and CO2 when confined in a vycor (SiO2) matrix. The field of fluids in confined geometries is...
