We have now established that multilayering at the air-water interface is a widespread phenomenon brought about by multivalent ions, whether polyelectrolyte, oligoelectrolyte or...

This proposal constitutes part of our ongoing study towards understanding how keratin, an important protein component of hair and skin, interacts with ionic surfactants using...

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

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...

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...

The immersion deposition of silver onto copper and brass from deep eutectic solvents (DES) is a novel method for protecting the surface of printed circuit boards. Background...

The strong interaction between polyelectrolytes and ionic surfactants can result in pronounced surface adsorption and the formation of surface multilayer structures. This...

Perfluoroalkyl substances (PFASs) are fully fluorinated, stabile, and surface-active compounds. They contain both a hydrophobic fluorinated carbon chain and an ionizable...

Increased environmental pressures and awareness is promoting a major drive towards an increased use of biosurfactants to produce more biosustainable and biodegradable consumer...

With the biobased economy growing substantially and pressure to reduce reliance on palm and crude oil derived materials, it is vital that the Home and Personal Care industry...

This proposal is part of a new project based on understanding the formation of gels in suspensions of partially oxidised cellulose nanofibrils with small amounts of salt or...

The aim of the proposed experiment is to carry out a series of SANS measurements on chain-grafted silica nanoparticles prepared in our laboratory. In this experiment we plan to...

Pyrite (FeS2) is a hydrophobic mineral surface, i.e. of a type thus far inaccessible to the types of aqueous adsorption experiments suitable for study by reflectometry (NR), but...

This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled...

In this work we explore how to use neutron reflection to study the interfacial adsorption from a natural eggshell membrane polypeptide at the oil/water interface. We will then...

In recent work with Unilever we have been investigating the structure of gels formed by partially oxidised cellulose nanofibrils for use in sustainable personal care products....

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...

Calcium ions have been shown in a preliminary experiment to have a dramatic effect on the thickness and structure of free supported bilayer films. In this proposal we...

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...

We propose to use the new SANS2d to study the dynamic structural evolution in the couse of the formation of DNA-cationic polymer complexes. The dynamic process and the mixing...
