Synchrotron developments of new techniques in X-ray interactions with matter, resolving major discrepancies in Quantum Physics and Chemistry. Synchrotron science is a priority area for Australia, the USA, and most first world countries. Development of new ideas and tools for X-ray investigations is the key to future opportunities and is the subject of this proposal. We will develop new techniques for crystallographic electron-density studies, X-ray Anomalous Fine Structure (XAFS) and Multiple-wa ....Synchrotron developments of new techniques in X-ray interactions with matter, resolving major discrepancies in Quantum Physics and Chemistry. Synchrotron science is a priority area for Australia, the USA, and most first world countries. Development of new ideas and tools for X-ray investigations is the key to future opportunities and is the subject of this proposal. We will develop new techniques for crystallographic electron-density studies, X-ray Anomalous Fine Structure (XAFS) and Multiple-wavelength Anomalous Dispersion (MAD), and provide useful advances for X-ray lithography and radiography. Simultaneous investigation of form factors, absorption coefficients, anomalous dispersion and X-ray scattering will provide new experimental tests of relativistic atomic wavefunction calculations, molecular bonding and solid state coupled cluster theory. Major discrepancies will be resolved.Read moreRead less
Gamma-ray spectra from electron-positron annihilation in molecules. Positrons and molecular electrons interact in new ways as compared to the electrons themselves, thus providing novel chemical possibilities. Australian expertise and the best available elsewhere will be combined to produce important new scientific results in this area and provide major training opportunities for young researchers.
How do biomolecules control excited-state dynamics? This project will use a combined theoretical and experimental approach to find out why non-fluorescent dyes become fluorescent when they bind certain biomolecules. This project's science will help guide the development of smart, biomimetic energy technologies and increase our understanding of how light powers living things.
Synchrotron X-ray absorption fine structure and fundamental X-ray interactions for nano-physics, chemistry and mineralogy. This project will develop new synchrotron techniques for measuring and interpreting X-ray data from materials targeting the nano-environment and bonding. The first wave of synchrotron nanotechnology is nascent. The project's X-ray methods develop techniques in applied mineralogy and catalysis. New insight will address key questions in chemistry, mining and biology.
