A number of studies have determined that non-ionic surfactants are capable of altering diffusionrates and transportation of both water and active ingredients thorough the waxy...

Acyl L-Carnitines are a group of novel surfactants with attractive physical and biological properties associated with their head group charge features. This work proposes to use...

Biosurfactants are becoming more commonplace in pharmaceuticals, vaccines and other forms of medicines. With the biobased economy growing substantially and pressure to reduce...

Over the last two decades, many polymers have been tested to increase CO2 viscosity for applications in enhanced oil recovery using CO2 (CO2-EOR). Unfortunately, conventional...

In this work we explore how our rationally designed peptide amphiphiles bind onto lipid monolayers using neutron reflection combined with deuterium labelling to the lipids,...

Nonionic surfactants usually do not show affinity to proteins and they work via competitive surface and interfacial processes in a binary mixture with protein. However, we show...

Studies by the Bristol group, and elsewhere [1, 2], have shown that highly branched hydrocarbon chains is the key factor for generating effective non-fluorous CO2 philic...

The bacterial cell envelope is one of the best targets for antimicrobial development. It is this envelope that harbours the instruments of microbial warfare, preventing its...

We have previously shown that peptides such as G(IIKK)4I-NH2 (G4) can kill bacteria and inhibit cancer cell growth whilst remaining benign to mammalian host cells. We have also...

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

Morphological features of plant waxes vary from species to species, but little is understood about what controls these morphological changes although it is widely believed that...

Nonionic surfactants usually do not show affinity to proteins and they work via competitive surface and interfacial processes in abinary mixture. However, we show in this work...

This proposal would like SANS time to better understand the LAS phase diagram. This has been prompted by recent experiments which show the system is not fully understood under...

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...

This proposal aims to investigate how the curvature of surfactant assemblies in water/dense CO2 systems can be tuned via the design and mixing of CO2-phillic surfactants. One...

gemini surfactants are essentially two surfactants joined by a linking chain. We have extensively explored cationic geminis at the air/water interface and they exhibit a range...

As part of a project concerning the fate of nanoparticles in the body we have been studying the kinetic and competitive (or cooperative) aspects of protein adsorption. HSA is...

The effects of electrolytes on SLES3, C12E8 and LAS4 has been extensively studied, especially the effect on the critical micelle concentration of each surfactant. We wish to...

Neutron reflection will be used to reveal the structural changes from different inner membrane leaflet models upon interacting with a group of antimicrobial lipopeptides with...

The increased prevalence of antimicrobial resistant bacteria is the most significant challenge facing the human-health today in both developed and developing worlds. It's...
