One of the grand challenges in the physical sciences is fabricating materials with a defect-free controlled structure on the submicron scale. Realisation of this challenge will...

Coacervates have been studied for a long time for their unusual properties: they are dense networks of charged polymers that are soluble in water. Instead of flocculating when...

Surfactants ability to lower surface tension and act as solubilising agents is critical for their wide use in everyday products. An oily hydrocarbon (HC) "tail group" attached...

In many applications, surfactants are formulated with a variety of additives to achieve a desired range of properties; polymers and cosurfactants/cosolvents (such as alcohols)...

In recent dielectric and calorimetric studies of some alcohol-water mixtures we have discovered unexpected and unexplained relaxation behaviours. Our aim with this proposal is...

Linear sodium alkylbenzene sulfonate (NaLAS) is one of the most extensively used anionic surfactant in the world, mainly as a biodegradable laundry detergent, with an annual...

At Kings College London we have recently developed a novel combination formulation, a nanosuspsomicroemulsion (NSME), comprising of a microemulsion (ME) containing one drug and...

Polymerisation-induced self-assembly is an efficient and versatile method of producing functional block copolymer spheres, worms and vesicles in a range of media (e.g. water,...

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....

The aim of the experiment is to employ SANS to study the physical properties of a novel and very stable aqueous Fe3O4 ferrofluid system stabilized by the commercially available...

Our group has been working partially oxidized cellulose nanofibrils which form gels in aqueous formulations. Recently we have observed that these fibrils also gel when dialysed...

Nanoemulsions (NE) i.e. nanoparticles containing a fluid lipid or oil dispersed in water and stabilized by a surfactant particles have attracted considerable attention as...

It is proposed that radioactive waste generated in the Netherlands be buried underground in Boom clay formations. As this will need to be stored for hundreds of thousands of...

Surfactants are known to charge colloidal surfaces in nonpolar solvents, but only a small number of different molecules have been explored. Recent experiments demonstrate that...

For biomaterial applications, it is important that the properties of self-assembled hydrogels are well controlled and match the requirements of the application. The influence of...

Our group has been working functionalised cellulose nanofibrils which form gels in aqueous formulations. Previously we have used these fibrils to stabilise oil-in-water...

Deep Eutectic Solvents (DES) are molecular mixtures similar to ionic liquids, having melting points below room temperature. DES share many of the features of ionic liquids (low...

Major technological and scientific challenges arise from the pressure to provide widely available and sustainable technologies for the societal requirements for health and a...

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

The aim of the study is to use SANS in combination with contrast variation to determine the effect of solubilising the lipophilic drug, testosterone propionate, in micelles...
