Redox conditions in the earth's upper mantle and the implications for kimberlite petrogenesis, diamond formation and mantle metasomatism. Diamonds are an important and high value commodity. Australia is the world's leading producer in terms of carats, due mainly to the massive Argyle deposit in northern Western Australia. Although diamonds form at great depths in the earth, they are accessible at the surface because they are transported by rare volcanic rocks, kimberlites and lamproites. Despite ....Redox conditions in the earth's upper mantle and the implications for kimberlite petrogenesis, diamond formation and mantle metasomatism. Diamonds are an important and high value commodity. Australia is the world's leading producer in terms of carats, due mainly to the massive Argyle deposit in northern Western Australia. Although diamonds form at great depths in the earth, they are accessible at the surface because they are transported by rare volcanic rocks, kimberlites and lamproites. Despite their importance the genesis of these rocks is poorly understood. This research will address this, providing scientific constraints on models for formation of diamonds and their host volcanics, which will directly inform the minerals industry's exploration models. There will be an economic benefit to the nation in terms of more successful outcomes from exploration expenditure.Read moreRead less
Understanding and controlling the stereochemistry of free-radical polymerisation. The stereochemistry of a molecule, which relates to the relative spatial arrangement of its atoms, can have a profound effect on its physical and chemical properties. This project will use a computer-guided experimental approach to design new methods for controlling the stereochemistry of the polymers formed in free-radical polymerisation.

The charXive challenge and the clean coal quest: thermokinetic principles and methods for capturing and sequestering carbon dioxide. Article 6 of the Kyoto Protocol, which Australia signed in 2007, states that a transfer of carbon credits may only take place if the associated activity provides a reduction in emissions by sources or an enhancement of removals by sinks that is additional to any that would otherwise occur. Since biochar production reduces emissions from biomass decay and transfers ....The charXive challenge and the clean coal quest: thermokinetic principles and methods for capturing and sequestering carbon dioxide. Article 6 of the Kyoto Protocol, which Australia signed in 2007, states that a transfer of carbon credits may only take place if the associated activity provides a reduction in emissions by sources or an enhancement of removals by sinks that is additional to any that would otherwise occur. Since biochar production reduces emissions from biomass decay and transfers oxidized carbon from the atmosphere to the inactive black carbon pool this project will contribute to the national effort in additional greenhouse gas abatements. The Australian Government is also committed to clean coal technologies, which are expensive. An economically viable method of capturing carbon emissions from electricity generators will result from this project.Read moreRead less

Changing your mind by changing your brain: An interventionist perspective on cognitive neuroscience. Functional neuroimaging provides a tremendous amount of information about the brain, but what it shows about the mind is less clear. Addressing this fundamental philosophical question requires developing a detailed account of theory-testing in cognitive neuroscience. This project aims to connect neuroimaging to theories of explanation that focus on the way one variable can make a difference to an ....Changing your mind by changing your brain: An interventionist perspective on cognitive neuroscience. Functional neuroimaging provides a tremendous amount of information about the brain, but what it shows about the mind is less clear. Addressing this fundamental philosophical question requires developing a detailed account of theory-testing in cognitive neuroscience. This project aims to connect neuroimaging to theories of explanation that focus on the way one variable can make a difference to another. By linking neuroimaging to facts about manipulable relationships between the brain and the mind, it will also provide a bridge between neuroimaging and complementary technologies for directly intervening on the brain. This, in turn, will provide a platform from which to explore the theoretical and ethical consequences of direct brain manipulation.Read moreRead less
Deciphering how plants control water and salt co-transport. This project aims to increase our understanding of how plant cells regulate solute transport. Crop growth depends on water uptake and transport, and the rapid movement of water across plant cell membranes requires transporters such as aquaporins. Preliminary data indicates that a series of signals can switch aquaporins between functioning as highly selective water channels and salt transport channels. The project aims to reveal the mole ....Deciphering how plants control water and salt co-transport. This project aims to increase our understanding of how plant cells regulate solute transport. Crop growth depends on water uptake and transport, and the rapid movement of water across plant cell membranes requires transporters such as aquaporins. Preliminary data indicates that a series of signals can switch aquaporins between functioning as highly selective water channels and salt transport channels. The project aims to reveal the molecular pathways that regulate water and salt co-transport, using genetics, molecular biology, and electrophysiology data to decipher how plants regulate and coordinate aquaporin solute transport during growth and in osmotic adjustment. The project has the potential to lead to improvements in crop-plant solute transport traits, enhanced agricultural productivity, and yield stability in saline and water limited environments.Read moreRead less
Cascading effects of Australia's ecological extinctions on biodiversity and ecosystem function. The current rate of species extinctions is so extensive that it has been described as the “sixth mass extinction”. In Australian ecosystems, extinctions and declines of mammals have been dramatic, with formerly abundant species now “ecologically extinct”, meaning they are too rare to continue to play important ecological roles. The loss of entire functional guilds may have cascading effects on biodive ....Cascading effects of Australia's ecological extinctions on biodiversity and ecosystem function. The current rate of species extinctions is so extensive that it has been described as the “sixth mass extinction”. In Australian ecosystems, extinctions and declines of mammals have been dramatic, with formerly abundant species now “ecologically extinct”, meaning they are too rare to continue to play important ecological roles. The loss of entire functional guilds may have cascading effects on biodiversity and ecosystem function. This project uses a multi-scalar experimental approach to investigate the broader impacts of mammal declines on Australian ecosystems, accounting for interactions with climate. The outcomes will include new insights into the pre-European state of Australian ecosystems and more realistic targets for ecosystem restoration.Read moreRead less
