We have recently developed novel ternary lipopolyplex vectors (i.e. gene delivery vectors containing cationic lipid, plasmid DNA and a cationic peptide) in which, for the first...

This proposal is part of a project based on understanding the formation of gels in suspensions of partially oxidised cellulose nanofibrils and small amounts of additives, such...

The efficiency of silicon solar cells is limited to 29%. One possible way of breaking this limit uses a process called singlet fission, converting a high energy photon into two...

Soluble pentacene derivatives are high performing semiconductors for use in organic transistors offering low cost solution processability, and potential for migration to...

Pluronic micelles are attractive candidates as drug carriers. Despite the abundance of data on their association with various drugs, there is, in contrast, very little...

This proposal aims to explore a cheaper and more environmental-benign surfactant system for yielding efficient water/CO2 microemulsions. The new surfactants permit high...

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...

Lecithin is a natural zwitterionic gemini surfactant that self-assembles in a hydrocarbon solvent, forming spherical or ellipsoidal inverse micelles, which grow into giant...

This proposal constitutes part of our ongoing study towards understanding the solution aggregation of collagen based polypeptides and their interactions with model surfactants....

The aim of this project is to develop an understanding of the relationships between the processing, nanoscale structure and device performance of bulk heterojunction,...

Emusifier distribution in concentrated dispersions

It is difficult for the naked external gene to become internalized due to its similar charge to the extracellular membrane surface. Various cationic copolymers and cationic...

In the proposed experiments we extend previous work on characterization of aggregates formed by cationic conjugated polymers and oligomers in water. Particular emphasis will be...

This projects aims to contribute to a better understanding of the relationship between processing conditions, active layer morphology and device performance in polymer solar...

Gene (nucleic acid) delivery to the cytosol or nucleus of a cell is, without the aid of a suitable delivery system, an inefficient process. Here the interaction of a defined...

Supercapacitors are devices capable of absorbing and delivering large amounts of energy over short time-scales. They are ideal for high-power/low-energy applications such as...

Amine-functionalised poly(alkylene oxides) are used extensively as swelling inhibitors in water-based drilling fluids. This study will broaden our understanding of the mechanism...

High internal phase aqueous-in-oil emulsions prepared by oil-soluble polyisobutylenesuccinicanhydride (PIBSA) with a water-soluble co-surfactant n-alkylpolyacrylamide (PAM)...

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....

We have synthesised alkyl phosphorylcholine (CnPC) surfactants in hydrogenated and deuterated form and have determined their solution aggregation using SANS. In this part of...
