The aim of this experiment is to characterise several novel ionic liquid ¿ oil and ionic liquid ¿ water microemulsions via SANS prior to their use in the synthesis of metallic...

We seek to investigate the non-equilibrium phenomena of a model polymer mixture by time-solved SANS and temperature jump experiments within (a) one-phase region and (b) one to...

This research project addresses an overlooked, but fundamental issue of colloid science: surfactant adsorption dynamics at nanoparticle-organosolvent interfaces. Adsorption of...

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...

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...

Polymer-surfactant mixtures are extensively used in a wide range of domestic, industrial and technological applications. This proposal is part of a collaboration between Oxford...

Small angle neutron scattering (SANS) will be used to characterise the structures of aggregates formed between the anionic conjugated polyelectrolyte...

Nanoemulsions have considerable potential for dermatological drug delivery. Small angle neutron scattering in combination with contrast variation will be used to characterize...

The aim of the experiment is investigate some nucleid acids to provide us with information about the size and shape when is dispersed in a solvent, so in a future studies to be...

The structures of emulsions formed from mixed oil-soluble and water-soluble amphiphiles (respectively derivatives of polyisobutylene, PIBSA, and polyacrylamide, PAM) will be...

This project concerns fundamental and strategically important research underlying the development of new drug delivery vehicles. We propose to sample phase diagram of...

This proposal is part of a broad programme of collaborative research between RAL / Oxford and Unilever, using predominantly scattering techniques to investigate the nature of...

The asphaltene fraction of crude oil is defined by its solubility parameters (insoluble in n-heptanebut soluble in toluene). Changes in conditions (temperature, pressure,...

Proteasome plays an important role in the processing of antigenenic proteins for presentation by the MHC class I pathway. PA28 is an activator of the 20S proteasome, a large...

The aim of the present study is to investigate the effect of different stimuli on a novel iron oxide core shell nanoparticles. The system is composed of a magnetite core with a...

There is a well-documented track record of research into water-in-CO2 (w/c) microemulsions. Using newly discovered CO2 compatible surfactants, the next step is to explore...

Lipopolysaccharides are amphiphilic macromolecules indispensable for the growth and the survival of Gram-negative bacteria, one of the most diffuse classes of pathogenic...

These experiments are part of a much broader programme at the University of Reading. focused on the use of water-soluble half-acetylated chitosan as a mucoadhesive polymer,...

This proposal is part of a new project which is a collaboration between Oxford, Newcastle, Ulster, and Unilever on the development of sustainable laundry detergents, using...

Surfactants have been used to bind and disperse Pt and Ru nanoparticles during their synthesis. In this work, we propose to use SANS to determine the thickness and packing...
