Recent SAXS measurements have indicated that CO2 can dramatically swell the surfactant layer in w/o microemulsions formed in CO2-swollen oils and also enhance solubilisation...

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

This proposal is part of a research programme which is focused on nano-fibres prepared by electrospinning. The programme is centered on the spinning...

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...

High internal phase water-in-oil emulsions can be efficiently stabilised by polymer amphiphiles for a static emulsion, and also show high shear stabillity even at elevated...

The aim of the study is to use SANS in combination with contrast variation to determine the effect of solubilising the lipophilic drug, testosterone propionate, in micelles...

The aim of the experiment is to employ SANS to study the physical properties of a novel and very stable aqueous Fe3O4 ferrofluid system stabilized by the commercially available...

This proposal continues our investigations into polyelectrolyte-surfactant solutions which form thin films at the air-solution interface. Our previous work has investigated the...

Despite interest in microemulsions as drug delivery vehicles, there is a lack of structural understanding to justify the formulations used. The present study examines the use of...

Progress in the development of nano-sized hybrid therapeutics and nano-sized drug delivery systems - "nanomedicines" - over the last decade has been remarkable. One key...

Surfactants have been used to bind and disperse Pt and Ru nanoparticles during their synthesis. In this work, we propose to use SANS to determine the thickness and packing...

This proposal is part of a new project which is a collaboration between Oxford, Newcastle, Ulster, and Unilever on the development of sustainable laundry detergents, using...

These experiments are part of a much broader programme at the University of Reading. focused on the use of water-soluble half-acetylated chitosan as a mucoadhesive polymer,...

Lipopolysaccharides are amphiphilic macromolecules indispensable for the growth and the survival of Gram-negative bacteria, one of the most diffuse classes of pathogenic...

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...

The aim of the present study is to investigate the effect of different stimuli on a novel iron oxide core shell nanoparticles. The system is composed of a magnetite core with a...

Proteasome plays an important role in the processing of antigenenic proteins for presentation by the MHC class I pathway. PA28 is an activator of the 20S proteasome, a large...

The asphaltene fraction of crude oil is defined by its solubility parameters (insoluble in n-heptanebut soluble in toluene). Changes in conditions (temperature, pressure,...

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...
