Environmental and Technological Applications of Electron-Driven Processes. We plan to use state-of-the-art experimental techniques and methodologies for the measurement of collision cross sections and reaction rates for low energy electron-driven process in molecules and molecular radicals. These processes are fundamental to our understanding of our environment and many devices used in the technology of today and of the future. In particular we will provide accurate cross sections for NOx and SO ....Environmental and Technological Applications of Electron-Driven Processes. We plan to use state-of-the-art experimental techniques and methodologies for the measurement of collision cross sections and reaction rates for low energy electron-driven process in molecules and molecular radicals. These processes are fundamental to our understanding of our environment and many devices used in the technology of today and of the future. In particular we will provide accurate cross sections for NOx and SOx pollutants and H2O, as well for molecules such as C4F8, and its radicals such as CF2, which are used extensively in plasma processing technologies.Read moreRead less
Correlation between surface force and morphology of self-assembled monolayer. As a most potential solid support for biological molecules without denaturing their functions, gold thiol self-assembled monolayers (SAMs) have been studied extensively for surface fabrication. In this project we will prepare functional monolayers using newly synthesized thiol derivatives, evaluate correlation between surface force and surface morphology of the SAMs using the surface forces apparatus, and optimize the ....Correlation between surface force and morphology of self-assembled monolayer. As a most potential solid support for biological molecules without denaturing their functions, gold thiol self-assembled monolayers (SAMs) have been studied extensively for surface fabrication. In this project we will prepare functional monolayers using newly synthesized thiol derivatives, evaluate correlation between surface force and surface morphology of the SAMs using the surface forces apparatus, and optimize the condition to fabricate biological devices such as immune sensors.Read moreRead less
Three-dimensional flow, temperature and melting distributions in mantle subduction zones. We will predict spatial distributions and time evolution of temperature and magma production in subduction zones, where cold oceanic plates sink into the Earth's mantle, recycle crust and sediments, and generate volcanic arcs. Three-dimensional laboratory experiments, including 3-D flow visualization and high-resolution temperature measurements, will model slab segments, different rates and modes of subduct ....Three-dimensional flow, temperature and melting distributions in mantle subduction zones. We will predict spatial distributions and time evolution of temperature and magma production in subduction zones, where cold oceanic plates sink into the Earth's mantle, recycle crust and sediments, and generate volcanic arcs. Three-dimensional laboratory experiments, including 3-D flow visualization and high-resolution temperature measurements, will model slab segments, different rates and modes of subduction and upward transport of melt. Ocean trench migration (?rollback? subduction) is of special interest because it gives patterns of temperature and vertical motion most conducive to melting. Results will be used to interpret geochemical and seismic data from the Tonga subduction zone in the South Pacific.Read moreRead less
Single Molecule Studies of Replisomal Function. It has recently become possible to watch the copying of DNA molecules with a specialized microscope in real time. This process requires assembly of a complex molecular machine on the DNA, followed by triggering of its function, and yields exquisitely detailed information about how the machine works. In this new collaboration between scientists in Australia and the U.S.A., we will assemble these machines on single DNA molecules, watch how they work ....Single Molecule Studies of Replisomal Function.

This process requires assembly of a complex molecular machine on the DNA, followed by triggering of its function, and yields exquisitely detailed information about how the machine works. In this new collaboration between scientists in Australia and the U.S.A., we will assemble these machines on single DNA molecules, watch how they work and simultaneously measure the very small forces that the machines generate. This will give Australian scientists access to a new technology for studying molecular machines.Read moreRead less
Understanding the chemistry and evolution of planets and their atmospheres: Integrating experiments, observations, and quantum mechanical models. Ongoing changes in the Earth's atmosphere, demonstrate the need to understand photochemical processes and their role in atmospheric evolution.

Ongoing changes in the Earth's atmosphere, demonstrate the need to understand photochemical processes and their role in atmospheric evolution. The proposed research will increase our understanding of the evolution of planetary atmospheres, with concomitant insight into the Earth's evolution. This proposal will greatly enhance the visibility of Australian research, through formal, direct connections to NASA and ESA (European Space Agency) planetary exploration missions, along with publications in Nature, Science, and/or PNAS (Proceedings of the National Academy of Sciences) that will likely result from the high-profile problems to be studied. Furthermore, as a result of this collaboration, Australian students and postdoctoral researchers will benefit from interactions with top international scientists.Read moreRead less
