Novel hybrid agricultural-byproduct/synthetic materials. The French partners have developed a method of converting low-value agricultural by-products into commodity plastics; however, the results are too water-sensitive to be useful. This project is to develop the science for grafting water-resistant moieties to this product, using mechanistically-based techniques developed by the Sydney group. The outcome would be technology for making useful materials from agricultural by-products that are cur ....Novel hybrid agricultural-byproduct/synthetic materials.

This project is to develop the science for grafting water-resistant moieties to this product, using mechanistically-based techniques developed by the Sydney group. The outcome would be technology for making useful materials from agricultural by-products that are currently of very low value in Australia.Read moreRead less

Scanning electron microscopy is a basic analytical tool for imaging surfaces of natural and synthetic materials and identification of nanometre-scale features and their compositions. At the University of Tasmania, it supports four of our six designated priority research themes: Antarctic and Marine Studies, Environment, Frontier Technologies, and Sustainable Primary Production. Our research depending on this technique includes many fundamental and applied topics from a wide range of disciplines, such as developing portable detection devices for explosives, finding more efficient and sustainable ways to explore for ore, investigating the effects of climate change on marine ecosystems and improving salinity and drought tolerance of crops.Read moreRead less
Disruption of Sex Pheromone Biosynthesis: A Novel Control Method for Pestiferous Fruit Flies by. Fruit flies from the genus Bactrocera are economically important worldwide. B. tryoni, (Queensland fruit fly) is the most damaging horticultural pest in Australia and B. oleae (olive fly) is a major European pest. These flies use chemicals of similar but distinct structure for communication and particularly for finding mates. This research will examine the pathways and enzymes these flies use to sy ....Disruption of Sex Pheromone Biosynthesis: A Novel Control Method for Pestiferous Fruit Flies by. Fruit flies from the genus Bactrocera are economically important worldwide. B. tryoni, (Queensland fruit fly) is the most damaging horticultural pest in Australia and B. oleae (olive fly) is a major European pest. These flies use chemicals of similar but distinct structure for communication and particularly for finding mates. This research will examine the pathways and enzymes these flies use to synthesise sex pheromones. We propose that understanding the chemical and biochemical steps employed by the flies will allow us to design inhibitors to prevent pheromone production and thus provide a novel, species specific method for controlling fruit flies.Read moreRead less

Preparation of Photo-Affinity Molecular Probes for the Identification of Gibberellin Receptors. Bioactive gibberellins affect numerous processes during plant growth and development, including seed germination, leaf expansion, stem elongation, flowering and fruit development. However, only very limited information is available regarding their mode of action at the molecular level. The central aim of the project is to prepare a family of photo-affinity molecular probes based on the gibberellin m ....Preparation of Photo-Affinity Molecular Probes for the Identification of Gibberellin Receptors. Bioactive gibberellins affect numerous processes during plant growth and development, including seed germination, leaf expansion, stem elongation, flowering and fruit development. However, only very limited information is available regarding their mode of action at the molecular level. The central aim of the project is to prepare a family of photo-affinity molecular probes based on the gibberellin molecule that will be designed to provide critical information on the location and structure of gibberellin receptors. Screening of the probes for potential effectiveness will be determined initially by the measurement of alpha-amylase produced in a standard barley aleurone assay.Read moreRead less
