Peptide-functionalized nanoparticle (NP) aggregates have significant potential as biosensors (for specific enzymes) due to their high sensitivity, modular design and simple...

An unusual set of systems, displaying key characteristics of microemulsions have been discovered using highly branched chain anionic surfactant stabilizers (Figure 1)....

The aim of our work is to study structural properties of supra-molecular assemblies formed in aqueous solutions of cationic pH- and thermo-sensitive block-gradient copolymers...

N-acyl amino acids are surfactants with attractive applications in different technological fields. They are referred to as mild surfactants because they are commonly considered...

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...

We are unravelling the solution structures of the Fab and Fc fragments in the IgA antibody family important in mucosal immunology. Having completed the structures for IgA...

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...

There is a well-documented track record of research into water-in-CO2 (w/c) microemulsions. Using newly discovered CO2 compatible surfactants, the next step is to explore...

This proposal is to probe the gel structure with High Pressure SANS (HP-SANS) using an in-line pressure cell. The ability to control the properties of supercritical CO2,...

Nanogranular thin films of FexM100-x (M=Au,Ag; x=7,20,39) are an excellent system to study the magnetism of nanoparticles in diamagnetic matrices coupled by direct, RKKY and...

Complex polymer architectures such as comb polymers have been studied for their highly customisable chemical properties. Potential applications have been identified in a wide...

We propose to look at the interaction of the aggregates two phospholipids form with two phospholipase (PL) enzymes, PLA2 and PLC, which hydrolyse different ester groups in the...

The aim of this project is to use SANS to determine if a critical micelle concentration (CMC) exists for the formation of inverse micelles in non-polar solvents. The CMC is a...

Surprisingly little work has been done to gain understanding about the nature, stability and properties of nanoparticles dispersed in organic solvents (organosols). Recently...

Hydrophobins are secreted fungal proteins and are small lipopeptide biosurfactants. They are strongly surface active and self-assemble at interface, and these unique film...

The aim of the proposal is to improve understanding about combinations of normal surfactants and hydrotropes. The systems of study are reference oil-water interfaces, provided...

The idea is to be able to ¿dial-up¿ the length and properties of CO2-philic and organo-philic rod-like micelles. This proposal aims to explore mixed surfactant systems in...

Low temperature embrittlement of stainless steels is due to phase separation and in this proposal we will further investigate the underlying mechanisms for phase separation....

This proposal aims to explore aqueous phase structures and compositions of a series of mixed surfactants. Although standard petrochemically-derived surfactant mixtures have been...

Bacterial lipopolysaccharide (LPS) is a bioactive structural amphiphilic molecule which forms the outer leaflet of the outer membrane of the Gram negative cell envelope. During...
