Gram negative bacteria cause a wide range of diseases. Colicins are protein toxins capable of penetrating the outer membrane barrier and killing the bacteria. Thus they...

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...

Deep Eutectic Solvents (DES) are a subclass of room temperature ionic liquids (ILs). They are mixtures of an organic salt with a hydrogen bond donor that form strong...

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...

The process of cell division requires precise duplication of the genetic material. The separation of the two strands of DNA and the progression of the replisome are driven by...

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

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

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

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...

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...

This SANS experiment was proposed by 4 PhD students from 3 different institutions in a Marie-Curie Training Network. They are all in the second year of their PhD and their...

Phase behaviour studies have identified hydrogen bonding as a key aspect in polymer solubility in fluorinated liquids, both in terms of solute-solvent and solute-solute...

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

This proposal is to perform SANS contrast measurements on three protein/DNA interactions currently worked on at the Research Complex at Harwell. This is part of an ongoing...

Non-ionic/metallosurfactant (P123/CTAF) mixed micelles are used as templates for the hydrothermal synthesis of mesoporous ferrisilicate materials. It was hypothesized that...

After initial and secondary oil recovery up to 50% of the oil can be left behind in the reservoir. Various enhanced oil recovery (EOR) techniques can be applied to improve the...

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

The aim is to probe the mixed micellar compositions of three common industrial fluorotelomer surfactants used in fire-fighting foam formulations (Figure 1) using contrast...

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

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...
