In this work we will investigate how the magnetic properties of nanometer thick iron-oxide films can be manipulated by heating them in air. Our preliminary results indicate that...

Topological insulators are one of the most important recent discoveries in condensed matter physics. The topological surface state can become gapped when ferromagnetic order is...

The aim is to use Neutron Reflectivity (NR) to gain essential information on adsorption properties of practical fluorotelomer surfactants used in fire-fighting foam formulations...

Magnetic rare earth/transition metal (RE/TM) multilayers have been a subject of considerableinterest in recent years, given the antiferromagnetic exchange coupling between RE...

We aim at studying proximity effects between a ferromagnetic thin film (either metallic or insulating) and a topological insulator (either undoped, or magnetically homogeneously...

The main objective of the present work is to gain an understanding of the interaction of the cationic protein, cyt c with anionic lipid membranes. This objective will be...

We will add temperature control to our reaction chamber for simultaneous neutron reflectometry(NR) and infra-red reflection absorption spectroscopy (IRRAS). This new set-up will...

In the present proposal neutron reflectivity will be used in combination with contrast variation to detect changes in the presence (and size) of microdomains in monolayer films...

Sulfobetaines are zwitterionic surfactants where the headgroup charges are arranged in the opposite manner to those found in phosphotidylcholine lipid headgroups. Sulfobetaines...

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...

This is one of a pair of linked proposals, one for SURF and one for INTER. The voltage response of poly(2-dimethylaminoethyl methacrylate) (PDMAEMA) weak polybase brushes...

Donated blood is typically stored in bags made of PVC plasticized with DEHP. DEHP migrates into the blood and the amount in the blood cells can be 5 to 10% of the phospholipid...

Lipopeptide surfactants are a group of interesting biosurfactants due to their natural origin and their high effectiveness at reducing interfacial tension. However, there is a...

We have recently developed methods for the extraction, separation and analysis of lipids from yeast cell cultures as physiologically realistic targets for membrane binding drugs...

Many drugs are both poorly water-soluble (hydrophobic) and lipophilic in nature and are therefore incorporated into surfactant micelles and monolayers. As the incorporation 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...

The Earth's climate is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and optical properties, important effects. Common...

Short peptide sequences consisting of hydrophobic and hydrophilic amino acid units are capable of self-assembly to lead to interfacial adsorption and solution nano-aggregation....

Foam stability, appearance and functionality is governed by the thin liquid films between foam bubbles. These films are stabilised by surface active molecules (surfactants and...

The main objective of the present study is to gain an understanding of the nature of the interaction of ¿phospholipid membranes¿ with small, interfering RNA (siRNA) in the...
