We have previously observed formation of polymer-surfactant films at the air-water interface having a range of structures including 2D hexagonal, bicontinuous cubic and lamellar...

Zwitterionics (here, alkyldimethylammonium carboxybetaines) are widely used in applications which require "mildness", e g cosmetics and isolation of membrane proteins, although...

The aim of the present study is to the determine, using specular neutron reflection (SNR), the structure of layers formed by novel tri-chain cationic lipids in combination with...

Projected climate change is strongly influenced by clouds. The oxidative processing of pollutants in clouds affects droplet size and reflectivity, important climatic effects....

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...

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...

CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of...

Previously we have examined the interaction of barley non-specific lipid transfer protein (nsLTP1) with OTS and lipid monolayers at the solid/liquid interface. Examining the...

Annexins are a ubiquitous group of membrane associated proteins found in animals, plants and fungi. They are linked to wide range of functions including phospholipid...

We wish to understand the mechanism to which polymer brushes such as PEO resist the adsorption of protein and thus offer biocompatibility for various surface applications....

Reflectometry is a technique that is capable of vector magnetometry. By selecting the appropriate valves of Q we could access the different forms of magnetic disorder, either...

The term cononsolvency has been used to describe a situation in which a polymer is less soluble in a mixture of two cosolvents than it is in either one of the pure solvents. If...

Nonionic surfactants usually do not show affinity to proteins and they work via competitive surface and interfacial processes in a binary mixture with protein. However, we show...

Nanoscale magnetic skyrmions are swirl-like magnetisation entities that satisfy topological quantisation conditions. They can therefore not be easily unwound into another...

Adsorption of a charged polyelectrolyte onto an oppositely charged substrate is important for the understanding of many natural molecular events as well as for the development...

We have previously shown that peptides such as G(IIKK)4I-NH2 (G4) can kill bacteria and inhibit cancer cell growth whilst remaining benign to mammalian host cells. We have also...

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...

By polarized neutron reflectometry we want to investigate the magnetic field profile in Y(1-x)PrxBa2Cu3O7/La(2/3)Ca(1/3)MnO3 high-Tc superconductor/ferromagnet superlattices. In...

We have recently improved the stability and coverage of free standing bilayers (FSB) by the use of a supporting thiolipid layer on gold. The system has been investigated on...
