This proposal is aimed at understanding the surface activity of the antibacterial agent, Triclosan, in the presence of surfactants. We request NR beam time on SURF to...

Using an enzyme mediated conjugation method we have prepared well-designed protein-polymer conjugates using a model protein, green fluorescent protein (GFP) with...

The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly is now emerging as an important structural signature associated with a wide range...

Lipopeptide surfactants are a group of interesting biosurfactants due to their natural origin and their high effectiveness at reducing interfacial tension. However, there is a...

Water-soluble conjugated polymers (WSCP) are an important class of materials which have received great attention as active materials in optoelectronic devices and in biosensing....

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...

Polymer-surfactant mixtures are extensively used in a wide range of domestic, industrial and technological applications. This proposal is part of a collaboration between Oxford...

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,...

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

Lipopeptide surfactants are a group of interesting biosurfactants due to their natural origin and their high effectiveness at reducing interfacial tension. However, there is a...

This proposal constitutes part of our ongoing study towards understanding the adsorption of collagen based polypeptide and its interaction with ionic surfactants at the...

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

An number of potential drugs, including steroidal drugs are extremely water insoluble, limiting their commercialisation as medicines. Solubilisation of drug in surfactant...

We have recently characterised a surface wetting transition for a low molecular weight oligomer in a high molecular weight rubbery polymer. Although weak surface segregation of...

PVA film is widely used as a non-toxic water soluble polymer. This proposal relates to its use in unit dose detergent pouches where plasticised PVA film stores a concentrated...

Complex polymer architectures such as comb polymers have been studied for their highly customisable chemical properties. Potential applications have been identified in a wide...

Perfluoroalkyl substances (PFASs) are used extensively in industrial products although have been identified as emerging pollutants accumulating in wildlife and environment....

Recently there has been a vast expansion in understanding about the interactions between oppositely charged polyelectrolyte/surfactant mixtures. The use of neutron reflectometry...

Polyions and biogenic polyamine are ubiquitous in many important biochemical functions. We propose here to use neutron reflectivity to investigate their potential to induce and...
