Liquid crystals (LCs) are known to act as good lubricants, however, the reason for this remains unclear. One contributing factor is thought to be the formation of ordered layers...

Coating two surfaces with polymer brushes has been shown on many occasions to reduce friction by orders of magnitude. These ultra-low frictions are believed to stem from be the...

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...

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

Hydrophobic drug encapsulation is one of the widely used strategies to overcome the poor adsorption and bioavailability of these drugs in vivo. Water-soluble amphiphilic...

The aim is to measure the preferential adsorption of one component in a nematic mixture. The base is 4-pentyl 4¿- cyanobiphenyl (5CB) and it is doped with 4-pentyl 4¿-...

A second-generation surface force style apparatus has been developed to probe the inter-surface and near-surface structures under compressive forces. Systems of current academic...

The adsorption of a liquid crystal dopant to a surface can have a significant impact on its properties such as electro-optic response and lubrication. The interesting adsorption...

Complex polymer architectures such as comb polymers have been studied for their highly customisable chemical properties. Potential applications have been identified in a wide...

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...

The research topic is encapsulation of a hydrophobic drug, flurbiprofen, using novel amphiphilic graft copolymers (AGCs). The AGCs of interest are shown in Figure 1: Preliminary...

For many applications such as paints, foods and drug formulations, aggregation of colloidal particles is prevented by combining polymer and surfactant adsorption. Key to this...

Small aromatic compounds are strongly solubilised by Pluronic block copolymers. This includes adjuvants, which are compounds used in the pharmaceutical industry to aid drug...

Polymers adsorbed or otherwise attached to interfaces provide an extremely powerful tool to control the forces that act between interfaces. The functionality of these attached...

The adsorption of a liquid crystal dopant to a surface can have a significant impact on its properties such as electro-optic response and lubrication. Both the interesting...

The behaviour of multiple polymers in competition for colloidal silica has previously been investigated in our group using solvent relaxation nuclear magnetic resonance. We...

Liquid crystals (LCs) are known to act as good lubricants, however, the reason for this remains unclear. One contributing factor is thought to be the formation of ordered layers...

Polymeric surface coatings are widely used to tailor the properties of surfaces. At the microscopic level, polymer layers provide steric stabilisation that gives colloidal...

The aim is to measure any tendency towards phase separation in a nematic mixture to complement an adsorption study on the same mixture. The base is 4-pentyl 4¿- cyanobiphenyl...

Carbon nanotubes are of great interest due to their unique properties, such as their high aspect ratio and electrical conductivity. Many possible applications of CNTs require...
