Halogenomethane derivatives exhibit thermally induced solid¿solid phase transitions before melting that are attributed to the ability to gain rotational degrees of freedom in...

Ferroelectric tetragonal tungsten bronze oxides (TTBs) have been extensively studied for their application dielectric and non-linear optical devices. TTBs often exhibit...

In a previous WISH experiment, we have succeeded in determining the incommensurate cycloidal magnetic structure of AgFeO2, which induces a ferroelectric polarization[1]....

Transition metal catalysts are ubiquitous in the academic and industrial study and application of synthetic chemistry. The properties of these catalysts can be augmented by...

Halide perovskites have been the focus of an intense research effort, ever since the discovery that they can be employed to fabricate highly efficient solar cells. One of the...

Diffusion of a range of cyclic hydrocarbons relevant to the nylon production process will be measured in the potential catalyst Pt/MCM-41 in the context of the benzene...

The thermoelectric properties of NaxCoO2 can be substantially improved by replacing Na ions by cations of higher valence. Our neutron diffraction studies on SXD for doping with...

This experiment seeks to resolve an ambiguity surrounding the structure of a prototypical relaxor ferroelectric Pb(Mg1/3Nb2/3)O3 (PMN). Relaxors have been studied extensively...

Water supports vital biochemical processes in living organisms, namely through maintenance of the three-dimensional architecture of biopolymers by a tight interplay with their...

The mechanism of high temperature superconductivity (HTSC) remains unresolved. Of particular interest is the origin of the mysterious pseudogap (PG, a partial gap in the...

The tellurides, M3TeO6, were recently reported as multiferroic The materials show complex behaviour with a series of commensurate and incommensurate antiferromagnetic phases...

Na2PdC2 and Na2PtC2 are the first examples of ternary alkali metal transition metal acetylides. They were synthesized and structurally characterised by our group in 2001 based...

Zaccai et al. proposed to build up a neutron Dynamics Data Bank which would be populated with dynamical data of biological macromolecules measured with different techniques,...

By adding only about 1% of soft polymer nanoparticles to natural rubber, a dramatic decrease in the viscosity (more than 50%) is induced. Our recent time of flight measurements...

High quality epitaxial films of the multiferroic BiFeO3 - PbTiO3 have been prepared using pulsed laser deposition. Using an electric field, we will induce a ferroelectrically...

Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this...

We propose to measure spin waves in detwinned SrFe2As2, combined with our data on detwinned BaFe2As2 this allows us to understand if magnetic excitations in the two systems can...

Human hair has been studied by x-ray diffraction and electron microscopy for many years, however a complete picture of its structure is still missing. Hair is a weakly...

The proposed experiment addresses the dynamics of surfactants in amphiphile/water systems during the topological transition, with a focus on the membrane with non-lamellae...

We use inorganic nanoparticles grafted with polymers as membranes for gas separation. These membranes show remarkable enhancement in permeability as compared to the bulk...
