Synthetic phenazines for enhanced biogas production from renewable and non-renewable resources. Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active p ....Synthetic phenazines for enhanced biogas production from renewable and non-renewable resources. Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active phenazines; understand the molecular mechanism by which phenazines increase biogas yields; and, assess the environmental consequence of phenazine application to coal seam gas production and anaerobic digestion of food waste. Phenazines are likely to emerge as a safe and cost-effective technology for improved biogas generation.Read moreRead less
Optimising Control of Hydroelectric Turbines Subject to Basslink Instability. With the introduction of Basslink, an underwater DC power cable across the Bass Strait, Tasmania will be connected to the national Electricity Market. Basslink will also provide an opportunity to utilise the significant water energy potential found throughout Tasmania. This project will examine the impact and disturbances due to the connection of Basslink with Tasmanian hydro power systems and develop control strategi ....Optimising Control of Hydroelectric Turbines Subject to Basslink Instability. With the introduction of Basslink, an underwater DC power cable across the Bass Strait, Tasmania will be connected to the national Electricity Market. Basslink will also provide an opportunity to utilise the significant water energy potential found throughout Tasmania. This project will examine the impact and disturbances due to the connection of Basslink with Tasmanian hydro power systems and develop control strategies for effective operation and control of hydro turbines with Basslink. Particular attention will be paid to the quality and reliability of electricity supply in Tasmania.Read moreRead less
Cosmic powerhouses: The birth, death, and legacy of black hole jets. This project targets relativistic jets powered by supermassive black holes - the most powerful systems in the Universe. Theoretically, the enormous energies released have a profound influence on how galaxies evolve; empirically, observations reveal signatures of their impact across cosmic time. However, fundamental questions remain about how these jets are triggered and what impact they have on galaxies. The project will addres ....Cosmic powerhouses: The birth, death, and legacy of black hole jets. This project targets relativistic jets powered by supermassive black holes - the most powerful systems in the Universe. Theoretically, the enormous energies released have a profound influence on how galaxies evolve; empirically, observations reveal signatures of their impact across cosmic time. However, fundamental questions remain about how these jets are triggered and what impact they have on galaxies. The project will address these questions using novel supercomputer models of black hole jets in realistic cosmological environments, then confront these predictions with new data from Square Kilometre Array (SKA) pathfinding radio telescopes. This will substantially enhance Australia’s leadership capacity in a strategically important area.Read moreRead less
Are ocean storms impacting Australia becoming more severe? This project aims to improve our understanding of the severe ocean storms that impact Australia. The novel approach will make use of multiple decades of the background 'noise', recorded continuously by earthquake seismic observatories, to locate and analyse ocean storms through time and identify changes in storm tracks. An interdisciplinary interpretation will follow which combines the large body of new results from seismology with data ....Are ocean storms impacting Australia becoming more severe? This project aims to improve our understanding of the severe ocean storms that impact Australia. The novel approach will make use of multiple decades of the background 'noise', recorded continuously by earthquake seismic observatories, to locate and analyse ocean storms through time and identify changes in storm tracks. An interdisciplinary interpretation will follow which combines the large body of new results from seismology with data from oceanography and meteorology. Significant advancement in our knowledge of severe storms will benefit Australia by indicating whether such storms are becoming more severe or, alternatively, if storm patterns are shifting.Read moreRead less
Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine ....Impact of hot gas on volcanic rocks and ore-forming processes. High temperature gases move from Earth's interior to the atmosphere at volcanoes, but little is known about how they react. Recent work shows that exceptionally rapid reactions occur between hot gases and the surfaces of solids. These reactions are instrumental in forming ore deposits. The proposed work aims to apply state-of-the-art chemical analysis of natural samples and investigate gas-solid reactions experimentally to determine how chemical elements, including metals, are distributed in these reactions. The study seeks to create robust geochenmical models for understanding geochemical and ore-forming processes. Improved understanding of ore deposition will enhance the long-term viability of Australia's metals sector.Read moreRead less
Submarine volcanoes: degassing of silicic magma with implications for ascent and eruption processes. This research project will advance the basic understanding of how magma ascends and erupts in submarine settings. This study will identify the relative roles and timing of volcanic gas release from silicic magmas, using cutting-edge techniques newly available at the Australian Synchrotron.
