Precise atomic-scale structure determination in thick nanostructures. This project aims to tackle a great challenge of atomic-scale characterisation: quantitative structure determination. Powerful new electron microscopes offer a window into the atomic world, but complex electron multiple scattering has limited reliable structure determination to ultrathin materials.

This project aims to tackle a great challenge of atomic-scale characterisation: quantitative structure determination. Powerful new electron microscopes offer a window into the atomic world, but complex electron multiple scattering has limited reliable structure determination to ultrathin materials. This project expects to overcome this barrier. Anticipated outcomes include methods that use the latest detector technology to determine structure and interatomic bonding in much thicker nanostructures than hitherto possible. This should benefit academic and industrial researchers by giving them new tools to understand and design high-performance materials for applications ranging from catalysis to energy storage to next-generation electronics.Read moreRead less
Imaging Symmetry – A New Mechanism for Revealing the Structure of Matter. This project aims to develop a revolutionary method for imaging atomic structures. In this method, the image contrast derives from the symmetry of the structure, measured at the picometre scale, using tiny electron probes. This new conceptual approach is expected to overcome some of the key limitations of existing electron microscopy methods by providing increased sensitivity and reduced radiation damage, thereby enabling ....Imaging Symmetry – A New Mechanism for Revealing the Structure of Matter. This project aims to develop a revolutionary method for imaging atomic structures. In this method, the image contrast derives from the symmetry of the structure, measured at the picometre scale, using tiny electron probes. This new conceptual approach is expected to overcome some of the key limitations of existing electron microscopy methods by providing increased sensitivity and reduced radiation damage, thereby enabling complex structures in technologically important materials to be determined. This should provide new ways to understand the properties of these materials advanced materials and engineer them for applications in the energy, transport, health, communications and other sectors of society.

Making every electron count in atomic resolution microscopy. The development of aberration-corrected electron microscopy, which allows individual atom imaging with unprecedented precision, was recognised by the 2011 Wolf Prize in Physics. However, only a very limited amount of the wealth of information obtainable from such microscopes is currently exploited.

The development of aberration-corrected electron microscopy, which allows individual atom imaging with unprecedented precision, was recognised by the 2011 Wolf Prize in Physics. However, only a very limited amount of the wealth of information obtainable from such microscopes is currently exploited. By collecting a maximal data set of electrons scattered in manifold different ways and using the fundamental theory of electron-specimen interaction, this project will realise the huge potential of this untapped data. This will improve the utility of scanning transmission electron microscopy far beyond its current level. Applying these new techniques will expand our understanding of the structure and function of advanced materials.Read moreRead less

This project aims to establish a triple beam ion and electron microscope facility for the modification, preparation and characterisation of materials that have hitherto been too sensitive for high resolution analysis with charged particle beams. It is expected that materials will be studied artefact-free and at the nanoscale with twin ion beams and new detectors that allow novel imaging modes and extreme chemical sensitivity plus controlled atmosphere transfer to other instruments for correlative measurements. This unique facility should benefit research in many disciplines such as physics, chemistry, geology, pharmacy, materials, civil and chemical engineering by allowing first-ever observations of vital phenomena in diverse materials.Read moreRead less
Chemical mapping of materials at the atomic scale. This project will develop a method for measuring the chemical composition of technologically important nanomaterials. This capability will provide Australian scientists with an advanced method for the characterisation of materials and will help them to develop new and better materials for future applications.
Novel advances in sub-nanometer imaging. After two decades of research the first wave of applications in nanotechnology and nanobiology is breaking. Immediately key to further progress in both areas is the ability to characterise the structure of such systems and also their evolution on very short time scales. This research project places Australia at the forefront in this endeavour.

Summary
Deterministic coherent diffractive imaging for the nanosciences. The technological trend towards nanoscale device fabrication demands picoscale measurements which will only be possible with the development of novel and advanced imaging techniques. This project will develop and implement cutting edge approaches to lensless imaging using both electrons and x-rays and will enable real-time imaging at the picoscale.
