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...

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

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...

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...

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

The interactions of neutral polymers with surfactants have a key role in detergency and are systems of current academic and commercial interest. Here, we propose to study the...

There is conflicting information about properties of polycrylic acid and its behaviour in aqueous solution. This proposal for an investigation by SANS that is directed at...

Conjugation of therapeutic proteins to polymers is well established but most methods result in multi-site and multiple conjugation, crosslinking resulting in lack of orientation...

Polymers and surfactants are key components in detergency. Understanding their interactions is essential to formulate smartly. Detergent formulations usually contain a mixture...

We have previously used LOQ to identify the complex (polyplex) structures formed between a short single strand DNA and a cationic diblock copolymer MPC30-DEA60. The SANS...

CO2 foams can be formed in water/carbon dioxide (W/CO2) mixtures with the aid of W/CO2 interfacially active hydrocarbon surfactants and surface treated silica nanoparticles...

Nanostructured lipid aggregates offer enormous potential as tools for membrane structural biology and biophysics. Styrene-Maleic Acid Lipid Particles have a number of attractive...

Amphiphilic linear surfactants based on PEO and PPO triblock copolymers, known as Pluronics, exhibit a rich polymorphism and have been extensively studied for their applications...

Bacterial lipopolysaccharide (LPS) is a bioactive structural amphiphilic molecule which forms the outer leaflet of the outer membrane of the Gram negative cell envelope. During...

Dye sensitised solar cells, based around colloids of the wide bandgap semiconductor TiO2 with bound dyes have potential to provide a cheap,sustainable source of solar energy...

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....

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