Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial ana ....Tree-mediated methane fluxes: A new frontier in the global carbon cycle. Methane is an extremely potent greenhouse gas. Recent evidence suggests that tree-mediated fluxes may be a significant, but overlooked source of methane to the atmosphere. This project aims to quantify the magnitude and drivers of tree-mediated methane fluxes from Australia’s dominant forest types. Innovatively, we will be using a novel combination of empirical field based measurements, gas tracer experiments, microbial analysis and modelling methods. Expected outcomes are a mechanistic understanding of tree-mediated methane fluxes, helping to constrain regional, national and global methane budgets. The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less
A new angle on the coalescence of drops. Many processes depend on what happens when drops and/or bubbles collide with each other, or with the surfaces of other materials. Examples include inkjet printing, agricultural spraying, spray coating of paints, pharmaceutical formulation, stability of cosmetics and foodstuffs, formation of froths and foams, and flow of bubbly liquids. To control these processes, we need to understand how and why drops sometimes do and sometimes do not coalesce with each ....A new angle on the coalescence of drops. Many processes depend on what happens when drops and/or bubbles collide with each other, or with the surfaces of other materials. Examples include inkjet printing, agricultural spraying, spray coating of paints, pharmaceutical formulation, stability of cosmetics and foodstuffs, formation of froths and foams, and flow of bubbly liquids. To control these processes, we need to understand how and why drops sometimes do and sometimes do not coalesce with each other or adhere to surfaces. The knowledge gained in this project will enable improvements to be made in the efficiency of processes such as those listed above.Read moreRead less
Brains frozen in time: vertebrate neural adaptations to invading land . The evolution of terrestrial animals from fish was one of the most significant events in our evolution, yet little is known about how the brain evolved during this transition. This project aims to investigate the major novelties acquired in the evolution of the early vertebrate brain in order to determine the functional reasons for such changes, as well as identifying the timing and environmental factors driving such changes ....Brains frozen in time: vertebrate neural adaptations to invading land . The evolution of terrestrial animals from fish was one of the most significant events in our evolution, yet little is known about how the brain evolved during this transition. This project aims to investigate the major novelties acquired in the evolution of the early vertebrate brain in order to determine the functional reasons for such changes, as well as identifying the timing and environmental factors driving such changes. This project expects to generate new knowledge on the anatomy of the vertebrate brain with improved methods for reconstructing fossil brains to better understand our own neurological evolution. Expected outcomes include enhanced institutional collaborations within Australia, and between Australia, Canada and the USA.Read moreRead less

The project aims to quantify brain anatomy on an unprecedented scale in comparative neurobiology. Focusing on Australia’s diverse and extensive collection of reptiles, including goannas, dragons and venomous snakes, the project expects to generate new knowledge on the evolution of brains as these animals adapted to new habitats and climates. Data will be collected by cutting-edge micro-CT technology and advanced phylogenetic techniques, which will be complemented by detailed neuroanatomy. Expected outcomes include enhanced understanding of the effects of temperature on brains, and a large database of 3D digital anatomical models. A major benefit includes a greater ability to mitigate the effects of environmental change.Read moreRead less
Designing and Building Novel 2D Hybrid Materials. The aim of this project is to use computational and experimental techniques to discover and fabricate new hybrid materials. Single-layer (2-D) materials like graphene have gained prominence and new ones are constantly being reported.

Gas Phase Reactivity of Charged Peptide and DNA Radicals: Fundamentals and Applications. Radicals derived from the "molecules of life", proteins and DNA, play both beneficial (e.g. enzyme catalysis) and deleterious roles (e.g. protein and DNA damage associated with disease).

Radicals derived from the "molecules of life", proteins and DNA, play both beneficial (e.g. enzyme catalysis) and deleterious roles (e.g. protein and DNA damage associated with disease). Two electrospray ionisation mass spectrometry approaches have been discovered to generate charged radicals of related models systems (e.g. peptides and nucleobases). The gas phase chemistry of these species is a largely unchartered area! We will examine the fundamental chemistry (unimolecular and bimolecular reactions) of these systems and build upon some exciting preliminary results which suggest potential applications (e.g. as a proteomics tool to sequence and distinguish between leucine and isoleucine residues in peptides).Read moreRead less

This project aims to exploit the behaviour of semiconducting polymer chains in solution to realise high-performance polymer electronics. This project will be achieved through a combination of simulation, theory, and X-ray measurements of solution-phase chain conformation and device studies. The project expects to create new predictive understanding of how the self organisation of semiconducting polymer chains determines thin-film microstructure and thus charge transport in thin-film devices. Expected outcomes include new materials and processes for high-performance polymer transistors and enhanced interdisciplinary research partnerships. This approach should hasten the development of new technologies based on lightweight flexible electronic devices.Read moreRead less

This is not possible with current theories. This project aims to find viable theories using a wide range of data from particle astrophysics and collider experiments. With the resulting knowledge, this project aims to design, optimise and implement better searches for new physics at the Large Hadron Collider (LHC). The new LHC results will be used to either determine the correct explanation for any new discoveries or alternatively to provide definitive limits on new theories. The results will be used to make high impact statements on the design of future facilities.Read moreRead less

This project aims to investigate the behaviour and origin of intraplate earthquakes in Australia by developing a multi-million-year record of earthquakes using geological, geochronological, geospatial, seismological, statistical and numerical modelling data. It will use maximum credible magnitudes, maximum shaking intensities of intraplate earthquakes and spatiotemporal relationships between large prehistoric and contemporary earthquakes to improve models of future seismic hazard in Australia and globally. This will lead to improved predictions of future earthquake impacts in urban and natural environments and development of new paleoseismic techniques.Read moreRead less
