Melanins are the major determinants of pigmentation of skin, hair and eyes in humans. These pigments originate from the tyrosinase-catalyzed oxidation of tyrosine, leading to...

Mixtures of colloidal particles of essentially two different sizes are commonly used in technological applications such as film formation on surfaces, paper coatings, etc....

We have recently prepared and studied the surface properties of some well-defined multi-end functional polyethylenes. Whilst most of our surface studies indicate that these...

In the proposed experiments we aim to characterise the structures of aggregate species formed when divalent metal ions, such as calcium(II), interact with the anionic conjugated...

The aim of this proposal is to investigate a novel approach to phase separation in microemulsions using careful choice of organic solvents, and appropriate mixtures....

This proposal aims to explore co-surfactants, as additives with CO2-active surfactants, for elongating reversed micelles in dense CO2 by using high-pressure small-angle neutron...

This proposal is part of a new research programme at Reading which is focused on a new types of macromolecular structures namely conetworks and pseudo-conetworks. These are...

This proposal is to probe the gel structure with High Pressure SANS (HP-SANS) using an in-line pressure cell. The ability to control the properties of supercritical CO2,...

New types of water-in-CO2 microemulsions using mixed surfactant systems will be investigated by high-pressure SANS (HP-SANS). Exciting new results (see report on RB820030) have...

We have recently embarked on a new 1 year project funded by Michelin to explore the self-associatation and mechanical properties of telechelic rubbery materials. Such materials...

Thus proposal seeks to explore the nature of electrospun composite fibres where the polymeric material contains a substantial quantity of biopolymer obtained from food waste -...

This proposal is part of a research programme at Reading which is focused on thermoresponsive supramolecular gels formed from self-assembling metallo organic polymers. These...

Metal carbonate particles dispersed in dodecane and stabilised with alkyl salicylate surfactants have been shown to aggregate when trace water is added. We have found that...

This proposal involves manipulating the curvature of aggregated polar materials in supercritical CO2 (scCO2) by tuning the mixing ratio of fluorocarbon (FC) and hydrocarbon (HC)...

We plan to carry out SANS experiments on a bacterial colonization factor to elucidate how it interacts with chitin, which is found on the surface of plankton and crustaceans....

An analogue of the popular surfactant AOT with isopropyl glycol tails (IG-AOT, Figure.1) has been recently designed as a co-surfactant for water-in-CO2 (w/c) systems: stable...

We propose to use the new SANS2d to study the dynamic structural evolution in the couse of the formation of DNA-cationic polymer complexes. The dynamic process and the mixing...

This proposal aims to explore aqueous phase structures and compositions of a series of mixed surfactants. Although standard petrochemically-derived surfactant mixtures have been...

This proposal is centered on the preparation of nanoscale fibres prepared by electrospinning and is the focus of the final year PhD programme of Saeed Mohan. These experiments...

We propose to use neutron scattering experiments to gain molecular level insight into an intriguing liquid structure observed in a water-free CO2-capture solvent. Switchable...
