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

The formation of multilayer structures at surfaces and interfaces from self-assembly in mixed surfactant and in polymer / surfactant mixtures has been recently reported, and...

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...

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...

The spontaneous formation of multilayer structures at surfaces and interfaces from self-assembly in mixed surfactant and in polymer / surfactant mixtures are being increasingly...

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