We are currently investigating the formation and structure of surfactant-templated polymer films comprised of cat-anionic surfactant mixtures and a variety of polymers. As we...

Mixed films of palmitic acid (PA) and galactocerebrosides (GCB) –a proxy for marine aerosol– exhibit attractive interactions due to H-bonding of galactose and carbonyl head...

The outer membrane (OM) of Gram-Negative bacteria (GNB) is an asymmetric structure which contains complex lipids known as lipopolysaccharides (LPSs) on the outer surface. LPSs...

Bacterial and fungal infections of cereal crops pose a considerable risk to global food security. Typically plant pathogens are controlled through the use of chemical agents...

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

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...

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...

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

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...

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...

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...

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...

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 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...

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...

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...

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...
