It is possible that there is a coupling between the spin and gravitation, for instance by an adaptation of the Hamiltonian with an additional termH=k/c (gvec.Svec) where gvec is...

Bacterial membranes contain safety valves called mechanosensitive ion channels, which protect the bacterium from changes in the osmotic pressure of their environment. However,...

This proposal is part of a major EPSRC (EP/GR065705)/Unilever funded programme to develop and control the spontaneous formation of surfactant multilayer structures at...

Accurate, safe and cheap hydrogen detectors functioning under a wide range of conditions are a vital ingredient for using hydrogen as an energy carrier. A novel, safe and cheap...

During the operation of nuclear plants, several fission products are released. Among them, radioiodine is considered one of the most important due to its tendency to form...

Observation of both ferromagnetic ordering and Kondo/heavy fermion behavior in a system is not so common. Recently we have discovered the Kondo effect/heavy fermion behavior in...

We have recently used a combination of PNR and low energy muon spin rotation (LEM) to detect the coexistence of an induced SDW and superconductivity in the superconducting layer...

The solid solution Mn(1-x)Fe(x)WO4 exhibits complex antiferromagnetic order with coexistence of commensurate and incommensurate magnetic structures. Furthermore, the MnWO4 end...

We use chemistry to arrange unusual crystal structures that set up conflicting interactions between magnetic ions in the material. In these compounds i is not possible for a...

Previous data obtained from neutron reflection shown in Figure 1 has clearly shown that the surface excess of some surfactants when adsorbed from aqueous solution to a sapphire...

Calcium ions have been shown in a preliminary experiment to have a dramatic effect on the thickness and structure of free supported bilayer films. In this proposal we...

Negative thermal expansion (NTE) materials, the volume of a material abnormally contract with the increase of temperature, is closed related to the magnetovolume effect in...

The compound, Si5O(PO4)6, is a component of a solid phosphoric acid catalyst, it has highly unusual coordination of the silicon (octahedral, as well as the more common...

We will use time-resolved specular neutron reflectivity measurements to follow the in-situ growth of polymer brushes by surface-initiated ATRP. This will enable us to determine...

The mineral gaudefroyite contains parallel chains of linked MnO6 octahedra. The Mn magnetic moments order with parallel spins within a given chain at low temperature, but the...

There is a great deal of interest in the Casimir force due its connection with quantum fluctuations, dark energy and nanotechnology applications. Measurements in plate geometry...

Lubricants contain a complex mixtures of polymers and base oils that must provide protection to moving surfaces with minimal energy loss due to friction or viscous drag. There...

"Chemical expansion" occurs when some ceramics expand upon releasing oxygen. Their ability to effectively "breathe" oxygen makes them of use in sustainable energy...

Schafarzikite minerals are structurally interesting in having 1-D chains of edge-linked transition metal octahedra. This experiment aims to determine the cause of the...

To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently...
