We have observed formation of polymer-surfactant films at the air interface having a range of structures, related to their solution interactions. The films form with...

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 propose to make neutron reflectivity measurements of hydrophillic polymers covalently attached, via thiol chemistry, to the gold-water interface. In particular, we will...

Plant-derived biosurfactants of the group of saponins offer an attractive alternative to synthetic surfactants because of their unique foaming and emulsifying properties...

We have shown that under certain conditions multilayer adsorption of surfactants occurs at the air-water interface. in which case the system becomes a powerful wetting agent (it...

Clarithromycin and Levofloxacin are essential antibiotics used to treat bacterial infections such as tuberculosis and pneumonia. Lung surfactants may be used as drug carrier of...

This experiment seeks to characterise the monolayer composition and structure of binary mixtures of fatty acid and amine. This represents a key additive system used commercially...

Chiral gemini surfactants containing stereogenic centers and two amphiphilic moieties, not only maintain the chiral properties, but also exhibit stronger aggregation properties,...

New detergents will increasingly rely on sustainable products and the use of enzymes will become ever more important. However, the process of destruction of stains (often...

Following our μSR experiment on liquid water (RB1720491) we propose to measure molecular diffusion coefficient (the sum of the diffusion coefficients of muonium and oxygen...

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

As it was predicted theoretically by Andreev at zero temperature for dilute 3He in 4He mixtures, 3He atoms will form a 2D Fermi liquid at liquid helium surface. Direct...

In a recent EPSRC / Unilever / Oxford CASE project we have used NR to explore and develop optimised delivery mechanism for active benefit agents such as perfumes. In particular...

The spontaneous formation of multilayer structures at interfaces from surfactant self-assembly has until recently been rarely observed. However, surface multilayer structures...

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...

Mn have been found to be an interesting ion to be used as dopant in Lithium Niobate (LiNbO3) crystals in order to enhance their photorefractive properties. These materials are...

The structure of colloidal crystals (dispersions of particles that spontaneously order in a regular array) is known to be influenced by solid boundaries. However there are few...

Due to a strong competition between other groups doing muSR study, we are submitting this proposal as a Rapid proposal. Recently, Wang et al. found the first nitrogen-containing...

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...

Considerable work has been carried out at ISIS with the aim of studying muoniated radicals in the gas phase by RF techniques. This has been motivated both by a desire to...
