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

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...

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...

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

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,...

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...

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...

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

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

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...

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

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...

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...

We have recently investigated a hybridization gap in Kondo systems using HET and several papers along with a review have been published. Our study shows a universal scaling...

For non-Fermi liquid compounds, the dynamical susceptibility, as determined from inelastic neutron scattering, is particularly interesting as it exhibits universal energy...

Spin ice materials are a class of compounds with exotic magnetic properties, resulting from the frustration. Magnetic monopoles have been detected at low temperature; manifest...

The myelin sheath is a multilayered membrane wrapped around axons in the vertebrate nervous system; it enables the rapid transmission of nerve impulses. It contains a set of...

Water plays a critical role in determining the structure and function of biological system. A hydration level, h~0.2 g water/g protein, is often found to be the minimum...
