We propose to study the competitive adsorption of a biosurfactant conventional surfactant mixture at the surface of an emulsion droplet in order to determine how these two...

Gram-negative bacteria, which cause a variety of diseases including meningitis, plague, sepsis and food poisoning, are becoming increasingly antibiotic resistant. One reason is...

Dendrimersomes are an exciting new class of vesicles, comprising bilayers of dendrimer molecules that can be engineered to have sensitivity to e.g. changes in pH and enzymes....

The properties of hydrogels are defined not only by their chemical composition, but also the spatial organization of their components. Applications that require a higher level...

Amphiphilic linear surfactants based on PEO and PPO triblock copolymers, known as Pluronics, exhibit a rich polymorphism and have been extensively studied for their applications...

Recently we have trialled the new techniques enabled on Larmor which permit simultaneous measurements of nanoscale and macroscale structure. These experiments gave new insights...

Bacterial lipopolysaccharide (LPS) is a bioactive structural amphiphilic molecule which forms the outer leaflet of the outer membrane of the Gram negative cell envelope. During...

This proposal aims to understand how the structure of non-ionic surfactant micelles affects the amount of fungicides solubilised. SANS is a technique unique for unravelling the...

This proposal aims to explore cheap and environmental-benign cosurfactants (or cosolvents) for yielding CO2-philic hydrocarbon surfactant/water/CO2 microemulsions (W/CO2...

It is well established that the anisotropy of nanoparticles has a dominant effect on increasing their uptake by cells. However, the advantage of anisotropy for cell penetration...

In this proposal we request beamtime on the Inter reflectometer to study the unexpected adsorption behaviour of the surfactant bis(2-ethylhexyl) sulfosuccinate caesium salt...

Dye sensitised solar cells, based around colloids of the wide bandgap semiconductor TiO2 with bound dyes have potential to provide a cheap,sustainable source of solar energy...

Contrast variation Small-angle neutron scattering (CV-SANS) will be used to probe structure of novel organogels made from surfactants and p-halophenols as low molecular weight...

Rhamnolipids are a type of glycolipid biosurfactant, produced as secondary metabolites by various Pseudomonas and Burkholderia species; they have been shown to possess...

Today, a number of technological devices, such as the readout sensor in the hard disc drive, have used the exchange bias (EB) effect, which arises in a...

In this proposal, we request beamtime to study the unexpected behaviour of a strongly bound bilayer of the cationic surfactant didodecyldimethylammonium bromide on the anionic...

Small angle neutron scattering will be used to directly quantify the adsorption of lecithin at the interface between partially deuterated sucrose particles contrast-matched to a...

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...

Solventless protein liquids (SPLS) represent a novel form of biological matter. Recently we reported on the preparation and properties of a solvent-free liquid protein based on...

Short peptide sequences consisting of hydrophobic and hydrophilic amino acid units are capable of self-assembly to lead to interfacial adsorption and solution nano-aggregation....
