With the pressing need for the reduction of Greenhouse emissions from electricity generation in Australia, one option that must be seriously considered is nuclear energy. However, the issue of waste storage is a highly significant one that must be addressed. Geopolymeric cements are expected to perform much better than traditional Portland cements in nuclear applications, both for solidification of radioactive wastes and also for the construction of underground waste storage bunkers. This project will use Australia's strong existing knowledge in geopolymers research, and apply it to the development of materials to fill the need for environmentally secure waste storage solutions.Read moreRead less

Production and nano-characterisation of II-VI semiconductor quantum dots from plant cell cultures. Nanocrystallites with semiconductor properties have potential applications in medicine, microelectronics and waste treatment.

Nanocrystallites with semiconductor properties have potential applications in medicine, microelectronics and waste treatment. Cheap, reliable methods for producing large quantities of monodisperse nanoparticles are required. Solution techniques have been used most commonly; however, production of stable, high-quality particles remains difficult. Biological synthesis using plant cell culture offers several important advantages. As peptide capping is incorporated into the biological assembly process, the nanoparticles are restricted in size, their stability is improved, and their surfaces are passivated. Application of plant cultures for nanocrystallite production is a novel approach with the potential to yield significant improvements in the quality of manufactured quantum dots.Read moreRead less

Wet granular materials are of immense economic importance in industries such as mining, agriculture, pharmaceuticals, and food processing. It has been estimated that operations involving the storage, handling and transport of granular materials account for over a third of the capital costs and over half of all the operating costs involved in process industries worldwide. An improved understanding of the dramatic effects of liquid on the cohesion, flow and mixing of granular materials will be of benefit to Australian industry both in terms of helping to reduce costly problems, such as caking and segregation, and in terms of the development of better particulate-based products, such as ceramics and pharmaceuticals.Read moreRead less

Granulation is the process that forms granular products with carefully targeted properties from powdery or liquid feeds. Granular products abound in the pharmaceutical, agricultural & industrial chemicals, and food & consumer goods industries. Poor understanding of the granulation causes delays in the time to market of new products and poor efficiency in large scale continuous granulation plants. This project will build on recent advances in the understanding of granulation fundamentals to (1) develop new robust design and scale up rules (2) develop intelligent control schemes for continuous granulation circuits, and (3) develop a new generation of regime separated granulators. The project is receiving substantial support from 3 industry partners (MSD Australia, Incitec and WMC Fertilizers) with cash contributions over 40% of the ARC grant requested, as well as very substantial in-kind contributions.Read moreRead less

Particulate materials are encountered in many different forms, sizes and environments, and vastly different areas such as biological, environmental, chemical and materials engineering. Particle size and its distribution are fundamental properties of these materials. Existing particle size measuring equipment in Australia is poor as currently available facilities cannot accurately resolve particle sizes in concentrated dispersions, nor can they visualise the in situ structure and size of fragile assemblies of particles (flocs). This proposal seeks funding for a suite of complementary particle size analysers, for use in an extensive number of research areas, to specifically address these critical current deficits.Read moreRead less
