Functional biomass carbons for low-cost sodium and potassium-ion batteries. The development of hard carbon anode materials for stationary rechargeable sodium and potassium ion batteries remains a major technological challenge. This project aims to utilise two very different biomass feedstock sources, sorghum and macadamia shell agricultural waste to manufacture low-cost, high-performance carbon anodes.

The development of hard carbon anode materials for stationary rechargeable sodium and potassium ion batteries remains a major technological challenge. This project aims to utilise two very different biomass feedstock sources, sorghum and macadamia shell agricultural waste to manufacture low-cost, high-performance carbon anodes. Current carbon anode materials such as graphite or carbonised sucrose, pitch or phenolics suffer from poor performance, high cost and/or low carbon yield and device durability issues. This project will investigate combinations of biomass precursors, tailored graphene and carbon alloys in order to significantly enhance anode performance while minimising cost.Read moreRead less
High-resolution optical studies of solids nucleation in cryogenic processes. During liquefied natural gas (LNG) production, low concentration impurities can freeze and block the cryogenic heat exchangers at the heart of the liquefaction process. Substantial knowledge gaps exist regarding the kinetics of these solids (i.e. the rate at which they form), especially at the part per million concentrations relevant to LNG. This project, in partnership with ExxonMobil Upstream Research Company, will us ....High-resolution optical studies of solids nucleation in cryogenic processes. During liquefied natural gas (LNG) production, low concentration impurities can freeze and block the cryogenic heat exchangers at the heart of the liquefaction process. Substantial knowledge gaps exist regarding the kinetics of these solids (i.e. the rate at which they form), especially at the part per million concentrations relevant to LNG. This project, in partnership with ExxonMobil Upstream Research Company, will use a proven high resolution optical technique to deliver new insight into solid nucleation and growth kinetics in the high-pressure cryogenic fluids that govern industrial blockage risk. The results will enable energy optimisation to increase liquefaction efficiency as well as tests of innovative blockage-remediation methods.Read moreRead less
Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based ....Nano-engineered catalysts for sustainable fuel production from waste . This project aims to address two major problems simultaneously-reducing the burden of non-recyclable waste currently going to landfill in Australia, and offsetting Australia’s reliance on imported diesel to support industry and transport needs. While approximately 95% of diesel consumed in Australia is imported, vast quantities of carbon-based waste ends up in landfill. Municipal Solid Waste (MSW) is a mixture of plant-based waste (including food, garden, paper, and wood) and fossil-fuel derived materials (plastics). Using an innovative and environmentally-sustainable catalytic process, the outcomes of this project are aimed alleviating Australia’s dependence on diesel fuel imports and better waste management solutions in Australia.Read moreRead less
Controlling arsenic to unlock value in gold and copper resources. This project aims to characterise the transformation of arsenic between oxidation states during mineral processing. Up to one third of the world’s gold reserves are locked up in arsenic rich minerals and 5000 tonnes of arsenic is released annually from mine waste. The project will enable the development of process technology that immobilises and removes arsenic at the earliest possible stage. The use of novel time-resolved in-situ ....Controlling arsenic to unlock value in gold and copper resources.

Up to one third of the world’s gold reserves are locked up in arsenic rich minerals and 5000 tonnes of arsenic is released annually from mine waste. The project will enable the development of process technology that immobilises and removes arsenic at the earliest possible stage. The use of novel time-resolved in-situ techniques proposed in this research will give vital information of the complex chemical pathways involved during processing which current characterization methods on pre- and post-processed species do not achieve.Read moreRead less
Low emission iron and steelmaking using hydrogen to pre-reduce lump ore. This project aims to develop and apply a new route of lump iron ore pre-reduction with hydrogen or H2-enriched gases for ironmaking to minimise CO2 emission from steel production. The route will be built up on the base of H2 reduction kinetics of iron ore and with novel technologies such as CO2 recycle and H2-heating using hot blast, underpinning the hydrogen economy by addressing the environmental concerns in mineral and s ....Low emission iron and steelmaking using hydrogen to pre-reduce lump ore. This project aims to develop and apply a new route of lump iron ore pre-reduction with hydrogen or H2-enriched gases for ironmaking to minimise CO2 emission from steel production. The route will be built up on the base of H2 reduction kinetics of iron ore and with novel technologies such as CO2 recycle and H2-heating using hot blast, underpinning the hydrogen economy by addressing the environmental concerns in mineral and steel industries. It is not only significant for low-carbon steel production, but also for better fundamental understanding to develop the future zero-emission iron and steelmaking with hydrogen. The project will be very beneficent because it increases the use of lump iron ore and expends Australian export of iron ores.Read moreRead less

The mining industry is processing low-grade ores associated with high amounts of waste minerals. Extracting metals from low-grade ores is very difficult with technical challenges in rejecting waste minerals. This project aims to understand the surface properties and the behaviour of a major waste mineral which is becoming increasingly problematic during the processing of copper and gold ores. New chemistry and chemical reagents will be developed to efficiently and economically reject the waste mineral by manipulating the reactions that take place on its surface. This project expects to have immediate economic and environmental impacts through increasing metal production, cutting greenhouse gas emissions and applying new green reagents.Read moreRead less

This project aims to engineer unique particles containing defect-intensive surfaces which are designed to accelerate the catalytic ozonation of waters contaminated with pharmaceuticals and other recalcitrant pollutants. This will enable timely treatment of industrial waste water as well as sewerage treatment plant effluents using simple and cheap catalyst materials. Wet- and flame-based particle fabrication technologies paired with unique post-synthesis treatment strategies, including either a coupled hydrogenation-illumination approach or plasma exposure, will be implemented for defect manipulation so as to produce new cheaper, stable, and higher-performing catalysts for activating ozone to treat water containing pharmaceutical and endocrine disrupting micro-pollutants under different process conditions.Read moreRead less
