The interface of CaCO3 (calcite) and water or oil is of paramount importance in a number of key academic and industrial areas, not least oil recovery and scale deposition in...

Inhibition of non-specific protein adsorption to surfaces is critical for proper functioning of medical devices. Different approaches have been developed for producing surfaces...

Despite the wide practical interest in particulate colloids there have been few studies that exploit the advantages of reflection and neutron scattering to study adsorption of...

In a recent experiment carried out on SURF we have shown that on addition of ethanol to a DPPC model membrane, the anaesthetic initially diffuses to the bilayer surface followed...

Adsorption maxima have been reported for adsorption at the hydrophilic solid/water interface based on measurements on powders and solution analysis. Many would claim that this...

Polymer-surfactant mixtures are widely used in commercial formulations in personal care, pharmaceutical and agrochemical, cleaning, automotive and food industries. The...

This proposal presents to directly measure ¿bridging¿ of anionic surfactants on an anionic surface through multivalent ions from water under well-controlled conditions (pHs and...

This proposal is part of a collaboration between Oxford and Ulster Universities and Unilever, on the development of sustainable laundry detergents, using a blend of conventional...

Stabilizers of colloidal particles are often complex and their function may involve several mechanisms to impart stability of a wide range of conditions. Sodium polyacrylate is...

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...

Surfactants responsive to pH, temperature, CO2, and light are known, however, our recent work has shown, for the first time surfactants that are magneto-responsive, and also...

This proposal is to explore adsorption of tetraalkylammonium (R4N+) counterions into monolayers of surfactant anions (see Figure 1) at the air-water interface, as a function of...

Perfluoroalkyl substances (PFASs) are stable compounds and commercially desirable. They are widely used, for example, as surfactants in textile and paper products and in aqueous...
