The effect of unsaturation on the shear dependence of cationic lamellar phase...
Products such as fabric and hair conditioners are commonly in the form of di-alkyl chain cationic lamellar phase dispersion. The effects of shear on such lamellar phase... -
Spontaneous multilayer formation at interfaces in mixed surfactant systems
The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly has until recently been rarely observed. However, surface multilayer structures... -
Curvature effects in polyelectrolyte-surfactant solution interactions
This proposal continues our investigations into polyelectrolyte-surfactant solutions which form thin films at the air-solution interface. Our previous work has investigated the... -
Ion mediated surfactant adsorption on cellulose films
In recent work with Unilever we have been investigating the structure of gels formed by partially oxidised cellulose nanofibrils for use in sustainable personal care products.... -
Structure of AOT layers at the sapphire water interface ¿ avoiding an isotope...
Several interesting results have emerged in studies of Aerosol-OT at the sapphire/solution interface that relate to effects of counter-ions, insensitivity to pH as well as the... -
Understanding the nature of perfume / surfactant interactions at interfaces
This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled... -
Adsorption of of hydrophobin and hydrophobin / surfactant mixtures at the oil...
Hydrophobins are secreted fungal proteins and are small lipopeptide biosurfactants. They are strongly surface active and self-assemble at interface, and these unique film... -
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... -
How polymer functionality influences multilayer formation at the interface in...
Spontaneous multilayer formation at interfaces from surfactant self assembly is emerging as an important structural signature associated with a wide range of potential... -
SANS study of the structure of surfactant stabilised Pt and Ru nanoparticles
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... -

Does ozone initiate damage to the main pulmonary surfactant lipid, DPPC, or c...
Exposure to ozone gas can cause inflammation of the airways and breathing difficulties. The initial reaction of ozone is thought to be predominantly with lipids present in the... -
Self-assembly in biosurfactants and biosurfactant / surfactant mixtures
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... -
Interactions between a mixture containing two cationic polyelectrolytes and a...
Recently there has been a vast expansion in understanding about the interactions between oppositely charged polyelectrolyte/surfactant mixtures. The use of neutron reflectometry... -
Using polymer / surfactant mixtures to optimise / enhance perfume delivery to...
This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled... -
Surface activity of biosurfactant (sophorolipid) / surfactant mixtures
Understanding the fundamental aspects of the surface adsorption and self-assembly of biosurfactant and biosurfactant / conventional surfactant mixtures is a major challenge for... -
Multilayer surfactant adsorption onto cellulose surfaces
Studying surfactant and mixed surfactant adsorption on model solid surfaces, which mimic real surfaces such as fabrics, hair and skin, is starting to provide a real insight into... -
