Discrete particle modelling and analysis of complex particle-fluid flows. Multiphase processes are widely used in both conventional and modern industries in Australia and worldwide, however rarely reach more than 60% of design capacity because of a poor understanding of their fundamental characteristics. This project aims to overcome this problem using an extensive combined fundamental and applied approach. The resulting theories, computer models and simulation techniques will be applied to imp ....Discrete particle modelling and analysis of complex particle-fluid flows. Multiphase processes are widely used in both conventional and modern industries in Australia and worldwide, however rarely reach more than 60% of design capacity because of a poor understanding of their fundamental characteristics. This project aims to overcome this problem using an extensive combined fundamental and applied approach. The resulting theories, computer models and simulation techniques will be applied to improve process design, control and optimisation. Consequentially, productivity and Australian competitiveness will be significantly enhanced in its most important industries such as minerals, metallurgical, chemical, energy, and materials.Read moreRead less

This project aims to develop photocatalysts via AC magnetic field through nanoscale heating for efficient H2 generation. This project is to introduce cold catalysis concept, which heats catalysts only but not solution, thus called cold catalysis, in the area of production of renewable energy. Expected outcome is the creation of clean and low cost catalysts to effectively harvest the chemical energy from the sun via splitting of water into H2 and O2 without causing any environmental damage. This unique technology will also help to address clean energy generation, which is in line with H2 economy plan by Australia government, and provide opportunities for new industries that will benefit Australian economy.Read moreRead less

Development of new steel products by thin strip casting and direct thermomechanical processing. The development of strip casting is now being driven by the opportunity to produce steel products with much lower utilization of energy, land and water and lower greenhouse gas emissions. However, this process represents a radical departure from conventional steel processes and therefore the factors that determine the final properties of the strip need to be understood and controlled under high rates ....Development of new steel products by thin strip casting and direct thermomechanical processing. The development of strip casting is now being driven by the opportunity to produce steel products with much lower utilization of energy, land and water and lower greenhouse gas emissions. However, this process represents a radical departure from conventional steel processes and therefore the factors that determine the final properties of the strip need to be understood and controlled under high rates of change. We believe that these challenges actually represent an opportunity to develop new high performance steel products that exploit the unique processing conditions of strip casting and that can use much more recycled material as a feed.Read moreRead less
Giant magnetic hardening in flash-annealed nanocomposite magnets. One of the most important properties required for permanent magnets is the coercivity. Recent results from an international collaboration between the Chief Investigator and researchers from the Japanese materials industry have shown that rapid heating can enhance the coercivity of chromium-added iron-neodymium-boron-based nanocomposite magnets by 30 times. The aim of this project is to clarify the mechanism of this giant magnetic ....Giant magnetic hardening in flash-annealed nanocomposite magnets.

Recent results from an international collaboration between the Chief Investigator and researchers from the Japanese materials industry have shown that rapid heating can enhance the coercivity of chromium-added iron-neodymium-boron-based nanocomposite magnets by 30 times. The aim of this project is to clarify the mechanism of this giant magnetic hardening effect and thereby establish a basis for further development of economically viable nanocomposite magnets with low neodymium content. Our novel flash-annealing process will allow exploration of new nanocomposite alloys, which may lead to Australian-owned patents.Read moreRead less

This project aims to develop innovative catalytic routes to the chemical recycling of mixed plastics for recovery of their molecular building blocks. Plastic pollution poses a significant threat to the Australian ecosystem. Efficient recycling technologies are urgently needed as Australia only recycles ~4% of its 3.4 million tons of mixed waste plastics. This project expects to design highly efficient catalysts for the stepwise breakdown of mixed polyolefin plastics into monomers for the subsequent manufacturing of virgin plastics in a circular economy, and to elucidate fundamental underpinning reaction mechanisms. Outcomes will stimulate the Australian waste plastic recycling industry, and minimise plastic accumulation in the environment.Read moreRead less
Geological sequestration of carbon dioxide in deep saline aquifers: coupled flow-mechanical considerations. Deep saline aquifers have been routinely proposed as sites for long-term, large-scale storage of carbon dioxide (CO2) emissions, as an option to assist the abatement of global warming.

This project determines the fundamental science underpinning the operation of a novel hybrid chemical looping carbon reforming (CLCR) process for production of alternative transportation fuels with a reduced greenhouse gas emissions profile.

To achieve the broad objectives of the project comprehensive experimental and modelling studies will be carried out at macro, micro and molecular levels. Expected outcomes include fundamental knowledge essential to the development and commercial-scale deployment of the CLCR process.Read moreRead less
