Perfluoroalkyl substances (PFASs) are used extensively in industrial products although have been identified as emerging pollutants accumulating in wildlife and environment....

We have now established that multilayering at the air-water interface is a widespread phenomenon brought about by multivalent ions, whether polyelectrolyte, oligoelectrolyte or...

Surface multilayer formation provides great potential for the tuning and optimising surface wetting properties and applications such as lubrication, drug delivery. Normally...

Sol-gel derived calcium silicates are of great importance due to their ability to bond to bone and stimulate new bone growth. Diffraction has revealed the atomic-scale changes...

In the proposed experiments we aim to characterise the structures of aggregate species formed when divalent metal ions, such as calcium(II), interact with the anionic conjugated...

In this novel proposal we will investigate adsorption onto the non-equilibrium face of calcite the first time this has been attempted. This will compliment and extend our...

We have found it possible to deposit mesostructured surfactant templated polymer thin films on solid substrates. To date the majority of work has used hexadecyltrimethylammonium...

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...

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...

Amino acid based surfactants have been known for many years but so far few detailed studies have been carried out on their properties. We are using amino acids extracted from...

The increasing incidence of pathogenic fungi resistant to treatment with amphotericin B (AmB) has created a demand for novel anti-fungal agents. The successful development of...

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...

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...

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...

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...

This proposal is part of a broad programme of collaborative research between RAL / Oxford and Unilever, using predominantly scattering techniques to investigate the nature of...

The spontaneous formation of multilayer structures at surfaces and interfaces from self-assembly in mixed surfactant and in polymer / surfactant mixtures are being increasingly...

Here we aim to structurally characterise the formation of adsorbed monolayers of heparin on calcite to address how these species influence biomineralisation and the inhibition...

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...

Addition of multivalent salts to water soluble polyelectrolytes, such as sodium carboxymethyl cellulose (NaCMC), induces conformational change to the polyelectrolyte structure,...
