Effect of drug on the micelles formed by ionic surfactants
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... -
Effect of pH on the shape of oil-in-water microemulsions formed by a zwitteri...
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... -
Effect of surfactant head group on micelle structure of drug containing micelles
The aim of the current project is to probe (at the nanometer length scale) the relationship between the solution structures of a surfactant molecule, the aggregate(s) it forms... -
SANS study of engine oil gelation
Metal carbonate particles dispersed in dodecane and stabilised with alkyl salicylate surfactants have been shown to aggregate when trace water is added. We have found that... -
Opening up microemulsion phases in CO2
New types of water-in-CO2 microemulsions using mixed surfactant systems will be investigated by high-pressure SANS (HP-SANS). Exciting new results (see report on RB820030) have... -
Viscosity modifiers for 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... -
Co-assembly of gold nanoparticles with wormlike micelles
Gold nanoparticles (GNPs) are attracting tremendous interest in nanotechnology due to their plasmonic properties, in particular the localized surface plasmon resonance effect... -
Structural characterization of a series of polymer-protein conjugates for chr...
Polymer-protein conjugates have been designed to deliver an appropriate target growth factor to promote a more rapid healing of chronic wounds, an incredibly important area for... -
Interaction of a pH-sensitive Polymer with a Model Lipid Membrane in the Form...
This SANS experiment was proposed by 4 PhD students from 3 different institutions in a Marie-Curie Training Network. They are all in the second year of their PhD and their... -
Aggregation of new silicon containing surfactants (NOT silicone surfactants)
The results from this experiment will develop alternatives to controlling surface tension through the design of 21st century surfactants (better performance at lower...
