Cause and effect: new mechanisms of particles formation in thunderstorms. This project aims to identify meaningful and specific indicators for predicting particle formation and alteration during thunderstorms. How thunderstorms develop is well-understood. However, identifying meaningful and specific indicators for predicting particle alteration during a thunderstorm is still not clear.

This project aims to identify meaningful and specific indicators for predicting particle formation and alteration during thunderstorms. How thunderstorms develop is well-understood. However, identifying meaningful and specific indicators for predicting particle alteration during a thunderstorm is still not clear. This project will practically contribute to the evidence of the impact of air particulates, thereby having direct implications for meteorological, and air pollution policy in Australia and worldwide. This project will allow researchers to understand the impact of these factors on the escalation of the causative effects, and to find a way to prevent unnecessary fatal outcomes.Read moreRead less
Pyrogenic carbon sequestration in Australian soils. Pyrogenic Carbon ('charcoal') is a poorly understood component of the global carbon cycle, important because it is resistant to degradation and hence has potential soil carbon sequestration benefits. This project applies a new technique (hydrogen pyrolysis), in combination with spectroscopic techniques, to quantify charcoal in a pan-Australian soil sample set, collected using uniform stratified sampling and preparation protocols. This will ena ....Pyrogenic carbon sequestration in Australian soils. Pyrogenic Carbon ('charcoal') is a poorly understood component of the global carbon cycle, important because it is resistant to degradation and hence has potential soil carbon sequestration benefits. This project applies a new technique (hydrogen pyrolysis), in combination with spectroscopic techniques, to quantify charcoal in a pan-Australian soil sample set, collected using uniform stratified sampling and preparation protocols. This will enable the mapping of soil charcoal stocks in relation to environmental and soil variables across Australia. The results will enable understanding of the controls on charcoal sequestration potential in Australian soils and contribute to efforts to quantify soil charcoal stocks and dynamics globally.Read moreRead less
Climate and environmental history of SE Queensland dunefields. This project aims to generate fundamental information about the timing and mode of formation of sand dunes in the world's largest downdrift sand system, Cooloola and Fraser Island, Queensland. The project aims to provide a world class record of climate variability, sea-level change and long term climate change from the sub-tropics of Australia, an area critical to understanding global climate links and sea-level change but where high ....Climate and environmental history of SE Queensland dunefields. This project aims to generate fundamental information about the timing and mode of formation of sand dunes in the world's largest downdrift sand system, Cooloola and Fraser Island, Queensland. The project aims to provide a world class record of climate variability, sea-level change and long term climate change from the sub-tropics of Australia, an area critical to understanding global climate links and sea-level change but where high quality long-term records are sparse and little investigated. This project will also underpin the outstanding universal value of the Fraser Island World Heritage Area which is based on the area being the world's largest sand island, but for which scientific understanding of the sand dunes is remarkably poor.Read moreRead less
Novel hybrid silica membranes for desalination. This project aims to produce high flux, highly stable ceramic membranes for use in desalination. This will result in novel, low energy desalination processes, delivering potable water at a greatly reduced cost.
Protected Action Ballots and Protected Industrial Action under the Fair Work Act: The Impact of Ballot Procedures on Enterprise Bargaining Processes. Under the Fair Work Act 2009 (Cth), lawful industrial action may be taken by employees in support of collective bargaining, provided that they have first authorised the action in a secret ballot. This research project explores the effect of the statutory process by which a bargaining representative of such employees seeks permission from the Fair W ....Protected Action Ballots and Protected Industrial Action under the Fair Work Act: The Impact of Ballot Procedures on Enterprise Bargaining Processes. Under the Fair Work Act 2009 (Cth), lawful industrial action may be taken by employees in support of collective bargaining, provided that they have first authorised the action in a secret ballot. This research project explores the effect of the statutory process by which a bargaining representative of such employees seeks permission from the Fair Work Commission to conduct a ballot. It will examine the impact of the ballot requirement and statutory process on decision-making by bargaining representatives and subsequent employee access to industrial action in order to understand the effect of the regulatory scheme on enterprise bargaining behaviour. It is the first empirical study of strike ballots, analysing an important public policy area.Read moreRead less
Towards a climate theory of tropical cyclone formation. In Earth's current climate, about 80 to 90 tropical cyclones form every year around the globe, but the reasons why cyclones form at this rate are unknown. This project will use a combination of theoretical techniques and numerical simulation to elucidate the links between large-scale climate and the rate of tropical cyclone formation. A series of climate model experiments will be performed that also have the potential to improve confidence ....Towards a climate theory of tropical cyclone formation.

This project will use a combination of theoretical techniques and numerical simulation to elucidate the links between large-scale climate and the rate of tropical cyclone formation. A series of climate model experiments will be performed that also have the potential to improve confidence in our predictions of tropical cyclone incidence in a future, changed climate.Read moreRead less
Reactivity and photochemistry of halide anions: atmospheric implications. Bromine and iodine are suspected to be responsible for most of the halogen-induced ozone loss in the stratosphere but are not currently included in atmospheric models due to a paucity of knowledge of the gas-phase chemistry and photochemistry of their anions and radicals. This project will develop and deploy advanced mass spectrometry and laser spectroscopy techniques to enable precision measurements of the reactions and p ....Reactivity and photochemistry of halide anions: atmospheric implications. Bromine and iodine are suspected to be responsible for most of the halogen-induced ozone loss in the stratosphere but are not currently included in atmospheric models due to a paucity of knowledge of the gas-phase chemistry and photochemistry of their anions and radicals. This project will develop and deploy advanced mass spectrometry and laser spectroscopy techniques to enable precision measurements of the reactions and photo-reactions of gas-phase iodide and bromide anions and their oxides. These state-of-the-art measurements of reaction kinetics and products will enable accurate chemical models that predict the impact of bromine and iodine chemistry on ozone levels and will inform future models for global climate.Read moreRead less
