This proposal aims to explore a cheaper and more environmental-benign surfactant system for yielding efficient water/CO2 microemulsions. The new surfactants permit high...

The excellent high temperature properties of Ni-base superalloys are derived from the presence of fine precipitates of the intermetallic Ni3Al phase, termed gamma prime. The...

The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly is an important structural signature associated with a wide range of technological...

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...

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

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....

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...

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...

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

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

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...

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...

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

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,...

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...

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...

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...

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...

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

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