This proposal is part of a major EPSRC (EP/GR065705) / Unilever funded programme to develop and control the spontaneous formation of surfactant multilayer structures at...

Liquid crystalline particles consisting of glycerol dioleate (GDO) / soy phosphatidylcholine (SPC) mixture and stabilised by polysorbate 80 (P80) have proven to be suitable as...

This proposal is part of a collaboration between Oxford and Ulster Universities and Unilever, on the development of sustainable laundry detergents, using a blend of conventional...

Amphiphilic protein surfactant interactions are becoming increasingly important in all aspects of soft condensed matter for drug delivery, flavour enhancement, foam stability...

Polymer-surfactant stabilised emulsion droplets are a potentially exciting route for micro-encapsulation of volatile agents (such as perfumes, flavours and many other benefit...

Hydrophobins are secreted fungal proteins and are small lipopeptide biosurfactants. They are strongly surface active and self-assemble at interfaces. Their unique film forming...

We request SANS beam time on LOQ to study the impact of multivalent counterions on the micellisation of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /...

The addition of multivalent counterions (Al3+, Mg2+) induces multilayer adsorption of ionic surfactants at interfaces. It is associated with strong wetting conditions, invoking...

Zwitterionic surfactants carry no net charge at the natural pH with no added electrolyte. This lack of overall charge makes their interactions with bio-systems weaker than those...

Adsorption maxima have been reported for adsorption at the hydrophilic solid/water interface based on measurements on powders and solution analysis. Many would claim that this...

We ask for 3 days of beam time on Inter/SURF to study the adsorption and adlayer characteristics of avidin on Ti surfaces, relevant for biomedical applications, such as...

There is an increased pressure towards incorporating biosustainable and biodegradable components in consumer products such as home and personal care products, cosmetics and...

The interaction of small polyelectrolytes or oligoions with surfactants appears to follow a model that we have recently established for large polyelectrolytes but the smaller...

Pore forming lipopeptides, such as Tolaasin, are produced by pathogenic mushroom bacteria, and are implicated in diseases such as ¿brown blotch¿ disease. They have potential...

This proposal is part of a major EPSRC (EP/GR065705)/Unilever funded programme to develop and control the spontaneous formation of surfactant multilayer structures at...

Surfactants usually form a single layer of molecules at the surface of water. We have shown that under certain conditions more than one layer may form. in which case the system...

Despite the wide practical interest in particulate colloids there have been few studies that exploit the advantages of reflection and neutron scattering to study adsorption of...

Surfactants usually form a single layer of molecules at the surface of water. We have shown that under certain conditions more than one layer may form. in which case the system...

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...

The MES is representative of a promising group of anionic surfactants which have the potential for improved performance and biocompatibility / biosustainability, and their...
