This proposal constitutes part of our ongoing study towards understanding the solution aggregation of collagen based polypeptides and their interactions with model surfactants....

Physical developer (PD) is a latent fingerprint development technique that is highly effective on paper and related surfaces, notably banknotes. The process exploits a redox...

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...

Hydrophobins are secreted fungal proteins in the form of small lipopetide biosurfactants. They are strongly surface active and self-assemble at interfaces and in solution. This...

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 aims to provide essential surfactant micellisation structural information of significant interest in its own right but also as key information for our on-going...

Although surfactant detergency is well understood above 30 C, actions of surfactants below 30 C are not well established. In the era of energy saving and environment caring, we...

Surfactants usually form a single layer of molecules at the surface of water. We have shown, surprisingly, that under certain conditions more than one layer may form. When this...

This proposal combines optical spectroscopy with neutron scattering using novel labelling strategies to investigate ?amyloid? protein fibrils. Variations in packing and in the...

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

In this proposal we investigate the adsorption of the key dispersant additive, sodium polyacrylate, used in colloidal systems using neutron reflection on aluminium oxide, with...

The complex sample environment needed for floating supported bilayers has often led to a need to constantly redevelop the system to improve reproducibility. Here we plan to...

Gemini-like and oligomeric-like surfactants can be constructed by single-chain or gemini surfacants with connecting molecules through noncovalent binding without complicated...

The understanding of the plant wax-surfactant interaction process is crucial to the development of more effective pesticide and fungicide formulations, essential for improving...

The Gram negative bacterial outer membrane protects the bacterium from external toxins such as antibiotics. This is partially responsible for Gram negative bacteria becoming the...

We have designed a series of cationic peptides with different helix repeats that can kill bacteria but remain benign to mammalian host cells. The selectivity to cell types is...

Studying surfactant and mixed surfactant adsorption on model solid surfaces, which mimic real surfaces such as fabrics, hair and skin, is starting to provide a real insight into...

In this proposal we investigate the adsorption of a key additive and functional group used in lubrication and wear applications using neutron reflection on a metal oxide...

We request NR beam time on SURF to study the impact of multivalent counterions on the surface adsorption of alkyloxyethylene sulfate surfactants and alkyloxyethylene sulphate /...
