Multi metal deposition (MMD) is a new latent fingerprint enhancement technique that is extremely effective on plastics, including drug wraps and explosives wrapping; it is also...

The biobased economy growing substantially and pressure to reduce reliance on palm and crude oil derived materials, demand that Home and Personal Care industries develops...

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...

Previous data obtained from neutron reflection shown in Figure 1 has clearly shown that the surface excess of some surfactants when adsorbed from aqueous solution to a sapphire...

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...

Hydrophobins, hfb2, are secreted fungal proteins, which are strongly surface active and possess powerful emulsion and foam stabilising properties. Understanding their...

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...

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...

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...

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

Antibody-antigen binding has been extensively used in many technological applications such as immunoassays, chemical analysis and bionanotechnology. The crucial element...

The methyl ester sulfonate. MES, and ethyl ester sulfonate, EES, are representative of a promising group of anionic surfactants which have the potential for improved performance...

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...

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...

An experiment performed on INTER last year found extreme non ideal mixing between C12E8/SLES3 at the air water interface: this feature became more extreme as the temperature...

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...

The addition of multivalent counterions (Al3+, Mg2+) induces multilayer adsorption of ionic surfactants at interfaces. It is associated with strong wetting conditions, invoking...

Our first completed photo-musr experiment on 6,13-bis(tri-iso propylsilylethynyl) pentacene (TIPS-Pn) has recently been accepted for publication. We observed a significant...
