This project seeks to develop a new class of electron field emitting nanocomposite consisting of nanotubes in liquid crystalline polymers. Electron emitting materials are in much demand in x-ray and microwave generation, computer displays and low-energy lighting. We utilise the ready alignability of liquid crystalline units in magnetic fields to cause realignment of incorporated carbon nanotubes, followed by polymer solidification to maintain orientation. It involves low temperature processing, contrasting very favourably with current problematic, high temperature processes. This allows materials to be cast on flexible polymer substrates, potentially enabling construction of cathode tubes to replace existing mercury-containing fluorescent lighting.Read moreRead less
Efficient ionic liquid-based reduction of nitrogen to ammonia. This project aims to develop a hybrid ionic liquid-nanostructured electrode platform to electrochemically convert nitrogen gas to ammonia. Ammonia production, mostly for fertilisers, consumes more than 1% of the global energy supply and contributes 1.6 % of global carbon dioxide emissions. A process that could convert nitrogen to ammonia using renewable energy would be an important alternative approach.

New polymeric nanocomposite coatings are proposed with enhanced abrasion resistance, toughness and optical functionality, suitable for the coating of optical plastic substrates. These composites contain inorganic cages, dispersed and chemically-coupled within the crosslinked organic matrix. In addition to good mechanical behaviour, high value properties such as colorisation on exposure to light and resistance to damage from high energy lasers will be achieved by attachment to the cages of chemical units with optical activity. These cages are of nanometre size and an important aspect of the project involves probing the resultant structure at the molecular level, using advanced characterisation techniques.Read moreRead less

Bioactive Polymer Platelets. This project aims to develop polymers that can be self-assembled into 2D structures. Most nanoparticles developed for drug delivery are spherical. However these are not always the most efficacious as theory suggest that non-spherical nanoparticles have longer circulation times. It is proposed that discoid morphologies may be advantageous as they tend to migrate to the vascular membrane and adhere more efficiently.

Most nanoparticles developed for drug delivery are spherical. However these are not always the most efficacious as theory suggest that non-spherical nanoparticles have longer circulation times. It is proposed that discoid morphologies may be advantageous as they tend to migrate to the vascular membrane and adhere more efficiently. The polymers developed by this project will be tailored towards bioactive and biocompatible material to create a drug delivery platform for more efficient disease treatment. The outcome will be better understanding on how polymer platelets can be obtained and how they compare in their biological activity with spherical nanoparticles.Read moreRead less

Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, whic ....Calcification of acrylic hydrogels in abiotic media: mechanism and control. Poly(2-hydroxyethyl methacrylate (PHEMA) and other acrylic hydrogels are extensively used as biomaterials, yet conclusive evidence exists that they have a propensity to calcify following implantation. This process has undesirable consequences on the functionality of various prostheses. Based on preliminary observations that PHEMA can promote the deposition of calcium minerals from media devoid of biological factors, which appears thus to be an inherent property of the polymer, the project aims at formulating new hypotheses to explain this phenomenon, and to confirm them experimentally. The "chelation" hypothesis will be validated by modifying the structure of polymers, and the "spontaneous precipitation" hypothesis by assessing the effect of solutes on the equilibrium water content of polymers. NMR and FTIR spectrometric techniques will be used to gain further insight into the mechanism of calcification. Methods to prevent the calcification will potentially result from these experiments, however, anticalcification agents will also be incorporated into hydrogels and their effect evaluated in calcification assays.Read moreRead less
