The aim of this experiment is to characterise several novel ionic liquid ¿ oil and ionic liquid ¿ water microemulsions via SANS prior to their use in the synthesis of metallic...

We intend to study the phase behaviour of 2 cationic polythiophenes, P3MAHT and P3ImiHT, in the presence of the perfluorinated surfactant potassium...

We shall use SANS to investigate the conformational behaviour of a range of amphiphilic copolymers with varying architectures: graft, hyperbranched block, hyperbranched random,...

We have been investigating the influcence of the cationic staphylococcal lipid lysyl-phosphatidylglycerol (L-PG) on bacterial resistance to antimicrobial peptides (AMPs). Using...

The aim of this experiment is to investigate surfactant aggregation in ionic liquids and also ionic liquid ¿ oil and ionic liquid ¿ water microemulsions via SANS. Contrast...

This proposal is part of a broad programme of collaborative research between RAL / Oxford and Unilever, using predominantly scattering techniques to investigate the nature of...

Amphiphiles derived from amino acids are important functional materials. The amino, carboxyl and side chain groups present in the chemical structure of amino acids provide wide...

Nanostructured lipid aggregates offer enormous potential as tools for membrane structural biology and biophysics. Poly(Styrene-Maleic Acid) stabilized lipid nanodiscs have a...

The use of polymer-drug conjugates for the delivery of drugs to specific sites of disease within the body has shown much clinical promise. It has become clear that the...

This proposal aims to explore organogel systems, like those recently decsribed1-3, but made from new CO2 philic surfactant-gelators. These have been synthesised to feature...

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...

Polyurethane foams (PUF) are commonly prepared by mixing Pluronic type copolymers and isocyanate reactive monomers in the presence of additives e.g. catalysts, blowing agents...

Recent results show that gold nanoparticles (Au-NPs) can be included into microgels (MGs). UV-visible spectra (Figure 1) suggest the original Au-NP sols retain their size and...

Ion transfer through fluid-fluid interfaces plays decisive roles in many natural and industrial processes. In studies of Cu(II) transport by Permeation Liquid Membrane (PLM)...

We have been studying the solution interactions leading to formation of solid polymer-surfactant films at the air-solution interface. We want to use the mesostructures in the...

This proposal continues our investigations into polyelectrolyte-surfactant solutions which form thin films at the air-solution interface. Our previous work has investigated the...

Proposal is focused on the study of the interactions of some lypopolysaccharides (LPSs) with Lactoferrin. LPSs compose about 70-80% of the outer membrane of Gram negative...

An analogue of the popular surfactant AOT with isopropyl glycol tails (IG-AOT, Figure.1) has been recently designed as a co-surfactant for water-in-CO2 (w/c) systems: stable...

This proposal is centered on the preparation of nanoscale fibres prepared by electrospinning and is the focus of the final year PhD programme of Saeed Mohan. These experiments...

CO2 foams can be formed in water/carbon dioxide (W/CO2) mixtures with the aid of W/CO2 interfacially active hydrocarbon surfactants and surface treated silica nanoparticles...
