Breaking bad oilfield emulsions. This project aims to use a solution of natural oil resin extract in carbon dioxide to break problematic water-in-crude oil emulsions with no secondary environmental consequences. Extracted crude oil contains water, which can result in problematic water-in-crude oil emulsions. These can be difficult to break into separate water and oil phases with potentially severe economic and environmental consequences. In Australia, such oilfield emulsion problems are frequent ....Breaking bad oilfield emulsions. This project aims to use a solution of natural oil resin extract in carbon dioxide to break problematic water-in-crude oil emulsions with no secondary environmental consequences. Extracted crude oil contains water, which can result in problematic water-in-crude oil emulsions. These can be difficult to break into separate water and oil phases with potentially severe economic and environmental consequences. In Australia, such oilfield emulsion problems are frequently encountered in both the Bass Strait and across the Carnarvon Basin. The treatment option proposed will target both asphaltene and silt stabilised water-in-oil emulsions and will be readily deployable.Read moreRead less
Does coevolution drive speciation? This project aims to connect micro-evolutionary processes with macro-evolutionary patterns to test the extent to which tightly coupled co-evolutionary interactions between species drive evolutionary diversification. The project will use techniques including the most recent phylogenetic modelling methods, field experiments and molecular genetics. Expected outcomes include advancing understanding of the mechanisms that generate biodiversity and developing new tec ....Does coevolution drive speciation? This project aims to connect micro-evolutionary processes with macro-evolutionary patterns to test the extent to which tightly coupled co-evolutionary interactions between species drive evolutionary diversification. The project will use techniques including the most recent phylogenetic modelling methods, field experiments and molecular genetics. Expected outcomes include advancing understanding of the mechanisms that generate biodiversity and developing new techniques for acquisition of DNA from museum specimens. The project is expected to provide significant benefits, such as insights into the processes that promote new species in nature.Read moreRead less
Understanding mosquito smell system: a new frontier in mosquito control. This project aims to identify and functionally investigate mosquito smell receptors, which are critical in detecting volatile compounds and locating their hosts from a considerable distance away. Mosquitoes display preferences for certain hosts over others, primarily determined by volatile chemicals produced by hosts. This study builds on recently discovered, novel, host-derived volatile compounds, which can elicit robust r ....Understanding mosquito smell system: a new frontier in mosquito control. This project aims to identify and functionally investigate mosquito smell receptors, which are critical in detecting volatile compounds and locating their hosts from a considerable distance away. Mosquitoes display preferences for certain hosts over others, primarily determined by volatile chemicals produced by hosts. This study builds on recently discovered, novel, host-derived volatile compounds, which can elicit robust responses and attractiveness from mosquitoes. Expected outcomes of the project are enhanced understanding of mosquito smell system and behaviours. This could provide significant benefits to how we can fight mosquitoes and mosquito-transmitted diseases in a more efficient and environmentally responsible way.Read moreRead less
Species redundancy in response to multiple disturbances. This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances. Studies that merely observe biodiversity change after disturbance cannot identify ecological processes connecting high diversity and e ....Species redundancy in response to multiple disturbances. This project aims to elucidate how the context within which disturbances occur affects food web linkages and how these map to responses in ecosystem function. There is a critical need to test the common assumption in environmental management that high biodiversity makes ecosystems resilient to disturbances. Studies that merely observe biodiversity change after disturbance cannot identify ecological processes connecting high diversity and ecosystem function, making experiments that manipulate identical disturbances in ecosystems with different biodiversity essential. This project will use field experiments that manipulate disturbances in streams replicated in low and high biodiversity regions and across gradients of chronic background stress to show how biodiversity sustains functional ecosystems, and how much diversity can be lost before ecosystems collapse.Read moreRead less
Next generation gas separations via innovative adsorption technologies. This project aims to develop new gas separation technologies that combine novel materials and pressure swing adsorption cycles to deliver inexpensive industrial processes capable of both high recovery and high purity products. The project will advance our ability to manipulate the phenomenon of regulated guest admission into microporous materials, and integrate such materials within new types of dual-reflux adsorption cycles ....Next generation gas separations via innovative adsorption technologies. This project aims to develop new gas separation technologies that combine novel materials and pressure swing adsorption cycles to deliver inexpensive industrial processes capable of both high recovery and high purity products. The project will advance our ability to manipulate the phenomenon of regulated guest admission into microporous materials, and integrate such materials within new types of dual-reflux adsorption cycles that deliver multiple refined gas products. Successful implementation of these industrial developments will increase Australia's access to cheap supplies of natural gas, encourage the broader use of biomass, lower the carbon emissions of industrial processes, and efficiently recover high-value compounds only present at trace concentrations.Read moreRead less
