We propose to use instruments SXD and WISH to carry out a detailed feasibility study of neutron protein crystallography at ISIS. Since one of the major impediments to protein...

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...

The complex sample environment needed for floating supported bilayers has often led to a need to constantly redevelop the system to improve reproducibility. Here we plan to...

There are specific models about the influence of shear on mixtures that are distinctive from dspersions of unifom particles. Understanding the flow behaviour of mixtures of...

In this proposal we request beamtime to study the unexpected behaviour of a strongly bound bilayer of the cationic surfactant didodecyldimethylammonium bromide on the anionic...

Cyclic peptides with alternating side chain stereochemistry are capable of self-assembling into long nanotubes. The conjugation of polymers to these peptides renders the...

The aim of this proposal is to determine the thickness of a water layer surrounding colloidal particles dispersed in oil with changes in ionic strength. Recent work by our group...

In this proposal we investigate the adsorption of the key dispersant additive, sodium polyacrylate, used in colloidal systems using neutron reflection on aluminium oxide, with...

Gram-negative bacteria, which cause a variety of diseases including meningitis, plague, sepsis and food poisoning, are becoming increasingly antibiotic resistant. One reason is...

gemini surfactants are essentially two surfactants joined by a linking chain. We have extensively explored cationic geminis at the air/water interface and they exhibit a range...

Hydrogen bonds are ubiquitous in materials across the chemical spectrum, from inorganic to biological. They influence the structure, the functionality, and therefore the...

We wish to extend previous studies on the adsorption of binary surfactant systems at the air water interface by the addition of NaCl and CaCl2: mimicking the 'hard water'...

It is now well established that the addition of the trivalent counterion, Al3+, induces surface multilayer formation in a range of anionic surfactants, including SLES, MES and...

This proposal constitutes part of our ongoing study towards understanding the solution aggregation of collagen based polypeptides and their interactions with model surfactants....

This proposal sets out to investigate the high pressure behaviour of the double perovskitematerial with the chemical formula La2NiMnO6. The properties of this and related...

In this project we propose to study the adsorption of methane onto a model mineral surface. This type of study is crucial to the understanding of the temperature dependence of...

The effects of electrolytes on SLES3, C12E8 and LAS4 has been extensively studied, especially the effect on the critical micelle concentration of each surfactant. We wish to...

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. in which case the system...

This proposal is about the development of sustainable detergency based formulations, based on the blending of biosurfactants with conventional surfactants, and is part of a CASE...
