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...

This proposal is a continuation proposal (previous RB 1110285) utilising the Offspec instrument and is aimed at further understanding the utility of the spin echo grazing...

The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly has until recently been rarely observed. However, surface multilayer structures...

Lung surfactant protein B, SP-B, is found at the air-water interface of the lung. A deficiency in SP-B at birth is known to be fatal. We have recently successfully studied the...

Nanogels because of their three-dimensional physical structure and tunable chemical properties as well as their stimuli-responsive nature have emerged as one of the most...

We propose to use neutron reflection to characterise the position and shape of subtilin/lipid II pore complexes as well as to characterise the kinetics of subtilin-lipid II and...

Antibody-antigen binding has been extensively used in many technological applications such as immunoassays, chemical analysis and bionanotechnology. The crucial element...

Our long-term aim is a detailed study of the Oriental Arms & Armour in the Wallace Collection, London, which contains nearly one thousand items and is one of the most...

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,...

We plan to investigate the interaction between amyloid proteins and model biomembranes deposited on solid surfaces. The model membranes will be single zwitterionic and mixed...

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...

As part of a wider study we are studying the effects of polymer architecture between cyclic and linear polymers. From ATR-FTIR measurements we observe clear differences between...

In recent years, it has become understood that rather than being homogenous mixtures, biomembranes show a complex phase behaviour, with regions of uniform phases, and others...

Titanium dioxide (TiO2) is used in a wide range of applications from medical and dental implants to treatment of contaminated air and water streams. However many of the...

By applying the regular solution model (RS) to the determination of composition in a mixed surfactant layer adsorbed at a hydrophilic solid/aqueous interfaceand combining it...

A number of important biological processes, such as intracellular transport and signal transduction depend on the viscosity and the distribution of microdomains in cells. We...

We have shown that under certain conditions multilayer adsorption of surfactants occurs at the air-water interface. in which case the system becomes a powerful wetting agent (it...

Surfactants usually form a single layer of molecules at the surface of water. We have shown that under certain conditions more than one layer may form. When this happens the...

We have previously shown that peptides such as G(IIKK)4I-NH2 (G4) can kill bacteria and inhibit cancer cell growth whilst remaining benign to mammalian host cells. We have also...

We have a long established interest in the materials used for the immobilisation of nuclear waste from the domestic power industry and legacy waste from various defence...
