Biosurfactants are becoming more commonplace in pharmaceuticals, vaccines and other forms of medicines. With the biobased economy growing substantially and pressure to reduce...

The balance of proteins adsorbed at a surface is important in a wide range of situations, e.g. implants, nanoparticles. The accepted model is that rapidly diffusing proteins...

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...

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...

Amino acid based surfactants have been known for many years, but so far few detailed studies have been carried out on their properties. We are using amino acids extracted from...

Soft polymeric nanoparticles possess many interesting properties. Those based on N-isopropylacrylamide are surface active and respond to changes in temperature. This give rise...

This proposal is part of a funded (CASE) project, aimed at understanding the delivery of benefit actives (perfumes) to interfaces and the development of new self-assembled...

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...

The strong interaction between polyelectrolytes and ionic surfactants can result in pronounced surface adsorption and the formation of surface multilayer structures. This...

DNA is a versatile building material for nanotechnology. We have recently studied a surface-tethered single-domain DNA motor by neutron reflection (IR) for the first time. We...

Organic solar cells (OPVs) are photovoltaic devices that can convert the energy from sunlight into electricity and have attracted much attention as a viable green energy source...

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...

The crystallisation of membrane proteins is of great interest, not least, to the pharmaceutical industry. We have recently begun a project aiming to investigate the role played...

Neutron reflectometery will be used to provide the vital information about the interaction/conformation of the organophosphonate compound on the lipid structure in the...

The aim is to establish the nature of the surface layer of 8CB at the nematic-air interface by measuring neutron reflection from the n=8, 10 and 12 homologues of the nCB series...

We will use time-resolved specular neutron reflectivity measurements to follow the in-situ growth of polymer brushes by surface-initiated ATRP. This will enable us to determine...

In our previous experiment we determined a value for the interfacial width of bare hexadecane-water interface. The NR-determined width was 6.0 ± 1.0 Å, which compares well with...

Conjugated organic semiconductors form an exciting class of materials that can be used in a variety of cutting edge technologies including organic light-emitting diodes (OLED),...

As part of a wider study we are investigating the effects of polymer architecture between cyclic and linear polymers. From ATR-FTIR measurements we observe clear differences...
