The pre-form rods this project yields will enable polymer optical fibre technology, just as suitable glass pre-forms enabled today's optical fibre. One-step casting techniques will yield PMMA rods with arrays of internal channels which can be empty, or filled with different clear polymer.

One-step casting techniques will yield PMMA rods with arrays of internal channels which can be empty, or filled with different clear polymer. Polymer microstructured optical fibre (PMOF) suitable for high bandwidth communications is then produced by drawing. It is urgently needed for local communication networks in cars and buildings. Solid PMOF channels are new to this project, and should make PMOF easier to deploy. Nanoscale mapping of light transport modes and polymer defects will help validate channel designs.Read moreRead less
An investigation of the mechanism of lacquer adhesion failure on electrolytic tinplate. "Tin" cans used for food packaging are actually made from tin-plated steel and, in most cases, the metal is coated with a lacquer. This lacquer is required to protect the can from corrosion and the contents from taint. The incidence of adhesion failure between the metal and the lacquer has increased recently for unknown reasons, causing considerable economic loss. This project will investigate the mechanisms ....An investigation of the mechanism of lacquer adhesion failure on electrolytic tinplate. "Tin" cans used for food packaging are actually made from tin-plated steel and, in most cases, the metal is coated with a lacquer. This lacquer is required to protect the can from corrosion and the contents from taint. The incidence of adhesion failure between the metal and the lacquer has increased recently for unknown reasons, causing considerable economic loss. This project will investigate the mechanisms of adhesion failure and improve our fundamental understanding of the problem. The results will be used to enable the selection of process conditions and lacquers that are more robust and reduce the incidence of adhesion failure.Read moreRead less

Efficient interconnection of photonic components is the most critical research problem facing the photonics industry in its efforts for integration. In this project, interconnects for photonic systems will be developed, utilising a recently developed new class of fibres - microstructured optical fibres, which have been called 'the next generation' of optical fibres because of their ability to produce a variety of tailorisable optical effects. Specially designed and modified microstructured fibres will be developed to achieve efficient coupling from fibre to planar waveguide circuits, and to a range of photonic band gap devices that are currently being developed by the industry partner.Read moreRead less

Microstructured optical fibres have been described as the 'next generation' of optical fibres, because of their ability to produce tailorisable optical effects. Our success in producing these fibres in polymer was a world-first. This project will yield a fundamental understanding of the fabrication process, so that for any fibre design the optimal drawing conditions can be determined and maintained for extended draws. This will allow improved draw reproducibility and fibre uniformity so that commercial quality fibres can be produced at economic rates. We will establish quantitative relationships between drawing parameters and optical properties, thus developing optimal designs and production processes.Read moreRead less

The link between composition, transport efficiency and output will be established. Input studies will include tailored external optics and full integration of bright LED's inside the cable. Prototypes evaluated will include, lighting inside display refrigeration, "on person" safety and fashion lighting (including novel jewellery), solar powered LED lighting for remote areas (including roadworks, stand alone signs, developing country and remote rural homes), daylight and lamps together in the one cable, and general lighting. Many of these will be developed by the industry collaborator.Read moreRead less
Nano-scale Modification of Paint Surfaces for Contamination Resistance. The main aim of this work is to develop a process to produce a dirt resistant paint surface. Dirt resistance is an important characteristic of prepainted steel sheets often used in architectural situations where dirt build-up is unsightly.

In addition work will be ....Nano-scale Modification of Paint Surfaces for Contamination Resistance. The main aim of this work is to develop a process to produce a dirt resistant paint surface. Dirt resistance is an important characteristic of prepainted steel sheets often used in architectural situations where dirt build-up is unsightly. To develop the process it will be necessary to understand the mechanism of dirt adhesion to paints and the modes of operation of current dirt resistant processes. In addition work will be required on the rate of surface segregation of additives to the paint solution. We propose to combine experimental and theoretical modelling approaches to obtain a fundamentally sound practical solution.Read moreRead less

The project will address the remaining challenge, the creation of a hermetic polymer seal, enabling the development of a small, light and highly efficient heart pump. The project has the potential to improve the lives of many Australians as our demographic profile shifts towards older people. Patients with advanced heart failure will live longer, with a higher quality of life. It will assist heart failure sufferers to remain productive members of our community, because many people who use the device will be fit to return to work.Read moreRead less

A new UV radiation polymerisation technique utilising charge-transfer complexes is adopted for synthesising novel hydrogels, a group of biomaterials for drug delivery. This work is significant as charge-transfer complexes, pertinent to the formation of hydrogels, form copolymers within the hydrogel matrices. This eliminates using costly, yet undesirable photo-initiators (PI), thus rendering the hydrogels as cleaner (PI-free) and more economical in production; the products present themselves as ideal treatment methods in the controlled-release of drugs, specifically targeting localised pathological sites of interest. The research findings will be invaluable to medical practices, leading to the creation of new industries in Australia.

The aims of this project are to develop and characterise hydrogel formulations for delivery of active agents, such as protein drugs, and to examine the biological responses to drug loaded hydrogels. In many medical and industrial fields, it is advantageous to control the release of active agents. Controlled release can decrease the dose of active that must be administered, sustain a more constant level of the agent in the environment and can localise the agent at the site where it is needed. This project will advance the theoretical knowledge of polymer degradation combined with protein release, will develop controlled release hydrogel technology that can be applied to medical devices and will train a postgraduate student in biomaterials and drug delivery.Read moreRead less
