Polymer displacement by surfactant at colloidal interface
The interactions of neutral polymers with surfactants have a key role in detergency and are systems of current academic and commercial interest. Here, we propose to study the... -
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... -
Conformation changes in aqueous medium of a water treatment protein from Mori...
Major technological and scientific challenges arise from the pressure to provide widely available and sustainable technologies for the societal requirements for health and a... -
Interaction between Rubisco and SDOBS at an air-water interface
Protein-surfactant interactions at an interface play an important role for broad applications in the chemical, dairy, cosmetic and pharmaceutical industries. Rubisco is the most... -
Interactions between phenylboronic acid modified polyacrylamides and surfactants
We are currently investigating phenylboronic acid modified polyacrylamides with variable phenylboronic acid block lengths as a route to glucose sensors with controllable... -
Surfactant mixing at hydrophilic solid/aqueous interfaces
By applying the regular solution model (RS) to the determination of composition in a mixed surfactant layer adsorbed at a hydrophilic solid/aqueous interfaceand combining it... -
In situ study of destruction of a denatured surface protein by protease (Savi...
New detergents will increasingly rely on sustainable products and the use of enzymes will become ever more important. However, the process of destruction of stains (often... -
interaction of a pharmaceutical water-soluble polymer with bio-relevant surfa...
We have been developing hydroxypropylmethyl cellulose (HPMC) microspheres for delivering poorly water-soluble drugs. The in vitro dissolution data showed that the presence of... -
Anomalous Layer at a Nematic-Air Interface using Thin Films
The aim is to establish the nature of the surface layer of 8CB at the nematic-air interface by measuring neutron reflection from the n=8, 10 and 12 homologues of the nCB series... -
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... -
Can surfactants be pushed out of polymer layers by applying compression?
For many applications such as paints, foods and drug formulations, aggregation of colloidal particles is prevented by combining polymer and surfactant adsorption. Key to this... -
Surfactant mixing at hydrophilic solid/liquid interfaces: (A) air/water measu...
The overall objective is to model the amount and composition of adsorbed mixtures of three types of zwitterionic surfactant and two charged surfactants at the silica/water... -
Nanoemulsions for dermatological drug delivery
Nanoemulsions have considerable potential for dermatological drug delivery. Small angle neutron scattering in combination with contrast variation will be used to characterize... -
Interactions between a polymer brush grown from a macro-initiator-modified sa...
We propose to make neutron reflectivity measurements of the weak polyelectrolyte, poly(dimethy amino ethyl methacrylate), grown from two different surface densities of initiator... -
Surfactant mixing at hydrophilic solid/liquid interfaces: (B) Solid/liquid me...
The overall objective is to model the amount and composition of adsorbed mixtures of three types of zwitterionic surfactant and two charged surfactants at the silica/water... -
Microemulsion formulations for local anaesthesia
Although microemulsions have been investigated as potential drug delivery vehicles, little work has been performed establishing the detailed molecular architecture of the... -
Structure of oil-in-water microemulsions containing eutectic mixtures of ment...
Although microemulsions have been widely investigated as potential drug delivery vehicles, relatively little work has been performed establishing the detailed molecular...
