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 purpose is to follow a structural evolution as water soluble (normal curvature) micelles are gradually transformed into oil soluble (reversed curvature) aggregates. Although...

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...

This proposal is part of a broad collaboration between Oxford, CCLRC, and Unilever in the study of surfactants and mixed surfactants at interfaces and in solution. This is an...

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

There is conflicting information about properties of polycrylic acid and its behaviour in aqueous solution. This proposal for an investigation by SANS that is directed at...

Time-resolved SANS will be used to investigate the mechanisms and kinetics of ordering of aseries of novel designed tetrapeptide-based hydrogelators. These inexpensive materials...

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...

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...

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,...

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...
