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
Wet Particulate Materials - Flow or Fracture? Most advanced materials are produced from starting materials in the form of fine particles. Powders, especially in ceramic engineering, are first processed wet into near-final shape. Improved understanding of the fracture of particle networks is critical in order to process nano-sized advanced ceramic materials for use in solar energy harvesting and extreme heat engine applications as well as minimising drying cracks in paints and coatings.

New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriat ....New Biomimetic Nanostructured Coatings for Hip Implants. Over 30,000 hip implants operations take place in Australia each year, due largely to a significant and growing proportion of the population suffering from conditions such as osteoporosis. The coating on the implants, required to cause good bone ingrowth and adhesion between bone and implant, is far from perfect. We propose to spray coatings which mimic the structure of bone, and thus offer improved mechanical properties such as appropriate rigidity and toughness, and stimulate better bone growth at the interface. In this way the implant should be much longer lasting and the need for undesirable revision surgery reduced. The processing technique proposed could also be a useful platform coating technology in a number of other industries.Read moreRead less

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.
