This project will investigate the formation and phase transition mechanism of these 1D particulates by various techniques. With such knowledge, we can effectively control the morphology on a scale of nanometers, and tailor the energy gap of these materials. This will significantly influence the photosemiconductive photocatalytic and lithium ions insertion behaviours of the particles so that advanced materials for solar energy conversion, photocatalysts for decomposing organic pollutants in environment, eletrode materials of lithium batteries can be developed.Read moreRead less
Renewable fuels and chemicals from fibrous organic waste and non-food crops. At current rates of resource usage, a world population with Australian standards of living would require between four and six planets. Solutions to existing and impending resource scarcity (water, power, chemical feedstocks) and associated greenhouse pollution are required in the short- to medium-term.

At current rates of resource usage, a world population with Australian standards of living would require between four and six planets. Solutions to existing and impending resource scarcity (water, power, chemical feedstocks) and associated greenhouse pollution are required in the short- to medium-term. The new catalysts and processes and their novel integration into an effective refining stream are designed to deliver the required breakthroughs, which will enable the broad adoption of lignocellulosic biomass for a sustainable solution. This is a major opportunity for Australia to address the fossil-fuel conundrum, and to show scientific leadership in an area that is set to drive economic and political change in the 21st century.Read moreRead less

This project will quantify the emission of carcinogenic pollutants, produced as a consequence of intended and unintended combustion of pesticides and pesticide-contaminated biomass. The project will identify specific pesticides and agricultural practices (such as burning of sugar cane prior to harvest or burning biomass contaminated with pesticides for energy recovery) which may become regulated in Australia. The research will benefit Australia socially, by reducing the emissions of polychlorinated dibenzo-p-dioxins and dibenzofurans and thus protecting the environment and the population, and economically by identifying pesticides that do not produce pollutants in combustion processes and thus do not contaminate biomass intended for energy recovery.Read moreRead less
