Liquid crystalline particles consisting of glycerol dioleate (GDO) / soy phosphatidylcholine (SPC) mixture and stabilised by polysorbate 80 (P80) have proven to be suitable as...

We shall use small angle neutron scattering to investigate the structural behaviour of the temperature sensitive highly branched poly(N-isopropyl acrylamide) [PNIPAM]. These...

The increasing incidence of pathogenic fungi resistant to treatment with amphotericin B (AmB) has created a demand for novel anti-fungal agents that can circumvent the...

Over the last two decades, many polymers have been tested to increase CO2 viscosity for applications in enhanced oil recovery using CO2 (CO2-EOR). Unfortunately, conventional...

A Unilever proprietary technology has been shown to inhibit biofilm growth and development, and is also found to possess antimicrobial activity, effective both as a...

We will use SANS to characterize dispersions of gold nanoparticles functionalized with poly(dimethyl aminoethyl methacrylate) brushes grafted from 25 nm gold nanoparticle...

Due to the naturally low viscosity of liquid CO2 (0.1-1.0 cP pressure/temperature dependent) the CO2 is prone to ¿fingering¿, limiting the efficiency of CO2-EOR [1]. In order to...

Progress in the development of nano-sized hybrid therapeutics and nano-sized drug delivery systems - "nanomedicines" - over the last decade has been remarkable. One key...

With the beamtime requested we plan to employ small-angle neutron scattering (SANS) to study novel nanocolloidal drug carriers prepared using lipids, surfactants and...

Amphiphilic copolymers with perfluoroalkyl blocks provide self-assembled nanostructures, in water, via the association and/or self-folding of the copolymer chains. This feature...

We shall use SANS to investigate the conformational behaviour of a range of amphiphilic copolymers with varying architectures: graft, hyperbranched block, hyperbranched random,...

Time-resolved SANS will be performed to investigate the effect of shear on the fibrillisation of insulin following denaturation. The rheological response will be measured...

Centrifugal force spinning is a technique that has recently come into light as an easy route to producing large quantities of nano- to micro- scale polymer fibres in a short...

The controlled synthesis of precious metal nanoparticles of the appriopriate chemical composition, optimised size and morphology for use in catalysis is an ongoing experimental...

We intend to study the phase behaviour of 2 cationic polythiophenes, P3MAHT and P3ImiHT, in the presence of the perfluorinated surfactant potassium...

This proposal continues our investigations into film-forming polyelectrolyte-surfactant solutions. We have found that mixed micelle systems offer greater control over micelle...

Bio-responsive polymers hold great promise as delivery vehicles for drugs, peptides and proteins as their chemistry can be tuned to effect a change in physico-chemical...

Recent studies implied an unusual headgroup (HG)-free, fluorocarbon (FC) surfactant Nohead FC6-HC4 to form stable, W/CO2 nanodispersions (W/C NDs). With the unusual surfactant...

The results from this experiment will develop alternatives to controlling surface tension through the design of 21st century surfactants (better performance at lower...

It has been recently shown that reversible thermal folding-unfolding, stabilization and high solubility of proteins (e.g. lysozyme) can be achieved when dissolved in protic...
