Formulating polymer solutions to stabilise polymeric foams
Polyurethane foams (PUFs) are commonly prepared by mixing Pluronic type copolymers and isocyanate reactive monomers in the presence of additives e.g. catalysts, blowing agent... -
Probing the thickness of the polymer adsorbed layer in HEUR stabilized oil in...
Oils are commonly used in personal care industry as emollients. Owing to their undesirable feel they are formulated in oil in water emulsions form. Emulsions contains... -
Competitive interactions in polymer-particle-surfactant blends
Many formulations comprise distinct chemical species that exhibit antagonistic or synergistic interactions that result in unpredictable behaviour. Previous work from our group... -
SANS Study of pH-Triggered Behaviour in Pluronic-Flurbiprofen Solutions: In v...
Hydrophobic drug encapsulation is one of the widely used strategies to overcome the poor adsorption and bioavailability of these drugs in vivo. Water-soluble amphiphilic... -
Effects of confinement on polymeric surfactants
Polymeric stabilisers are often used in the preparation of emulsions and dispersions of particles. The purpose of this additive is to help keep the mixture stable so that it can... -
Characterisation of structure for the determination of liquid thermodynamic c...
This proposal is a continuation of prior combined NMR, SANS and diffraction measurements to characterise templated silicas, as part of a program to inform the behaviour of... -
On the peculiarities of the structure of particle stabilised foam
Many formulated products pass through or end up as foams, comprising immiscible millimeter sized bubbles dispersed into an aqueous continuous phase. Frequently, surfactants or... -
Polymer conjugates for drug delivery
Complex polymer architectures such as comb polymers have been studied for their highly customisable chemical properties. Potential applications have been identified in a wide... -
The effect of particles on the structure of mucin ¿ understanding the challen...
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... -
Solution aggregation of short peptide surfactants
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.... -
A SANS Study on the Influence of Shear on Peptide Fibrillisation
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... -
Adsorption of an Anionic Surfactant on Anionic Surfaces in the Presence of Po...
In this proposal, we request beamtime to study the very unexpected adsorption behaviour of the surfactant bis(2-ethylhexyl) sulfosuccinate potassium and ammonium salt (K(AOT)...
