Polymeric films thinner than a 100 nm exhibits a variation of the glass transition temperature of a few tens of degrees and can brake up into discrete islands when heated near...

We have previously observed formation of polymer-surfactant films at the air-water interface having a range of structures including 2D hexagonal, bicontinuous cubic and lamellar...

Zwitterionics (here, alkyldimethylammonium carboxybetaines) are widely used in applications which require "mildness", e g cosmetics and isolation of membrane proteins, although...

Lipid compositional variation across the cell's membranes as well as asymmetry between two contiguous monolayers in the same membrane are critical for alive and healthy cells....

This proposal is to explore adsorption of tetraalkylammonium (R4N+) counterions into monolayers of surfactant anions (see Figure 1) at the air-water interface, as a function of...

The aim of the present study is to the determine, using specular neutron reflection (SNR), the structure of layers formed by novel tri-chain cationic lipids in combination with...

This proposal continues our work into surfactant templated films formed from surfactant/polyelectrolyte solutions. Recently we have been studying the encapsulation of...

Protein-lipid\membrane interactions are fundamentally important to biological processes. We have examined the role protein hydrophobicity in protein-membrane interactions...

Surfactants responsive to pH, temperature, CO2, and light are known, however, our recent work has shown, for the first time surfactants that are magneto-responsive, and also...

Neutron reflectivity will be used to investigate the composition in the direction perpendicular to the substrate for films of blends of electron-donor...

Many proteins exhibit a lag in lowering the surface tension at the air-water interface. The origin of this lag is not well understood either experimentally or theoretically. The...

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...

Previously we have examined the interaction of barley non-specific lipid transfer protein (nsLTP1) with OTS and lipid monolayers at the solid/liquid interface. Examining the...

Annexins are a ubiquitous group of membrane associated proteins found in animals, plants and fungi. They are linked to wide range of functions including phospholipid...

We wish to understand the mechanism to which polymer brushes such as PEO resist the adsorption of protein and thus offer biocompatibility for various surface applications....

Increased environmental pressures and awareness is promoting a major drive towards an increased use of biosurfactants to produce more biosustainable and biodegradable consumer...

The presence of a monolayer of surfactant material at the air-water interface of the lung is crucial for respiratory function. It is well known that exposure to the ubiquitous...

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 increasing incidence of pathogenic fungi resistant to treatment with amphotericin (AmB) has created a demand for novel anti-fungal agents that can circumvent the pathogens¿...

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...
