Understanding graphitization: developing a model for activated carbons. For over 60 years it has remained a puzzle why some carbons graphitise under heating while others do not. The question is of practical importance as oxidation of non-graphitising carbons produces activated carbon, a product of high value with industrial, medical and environmental applications. Using computational and experimental techniques the project will study the graphitisation process and pinpoint the structural element ....Understanding graphitization: developing a model for activated carbons. For over 60 years it has remained a puzzle why some carbons graphitise under heating while others do not. The question is of practical importance as oxidation of non-graphitising carbons produces activated carbon, a product of high value with industrial, medical and environmental applications. Using computational and experimental techniques the project will study the graphitisation process and pinpoint the structural elements which inhibit it. Based on these findings the project aims to develop a nanoscale atomistic model for activated carbons. This is expected to be an important contribution to the field of chemical engineering in which current models of activated carbon neglect either curvature in the network or the presence of oxygen.Read moreRead less
Enabling semiconductor nanowire technologies via 3D atomic-scale insight. Semiconductor nanowires (NWs) are nanotechnology building blocks that have the potential to transform solar cells, light emitting diodes, lasers and transistors, creating new industries in communications, energy and healthcare.

Semiconductor nanowires (NWs) are nanotechnology building blocks that have the potential to transform solar cells, light emitting diodes, lasers and transistors, creating new industries in communications, energy and healthcare. The industrial development of NWs has been blocked by uncertainties in the relationships between their growth conditions, properties and atomic-scale structure. This project will address this challenge by establishing a rigorous framework for these relationships. The project aims to achieve this by harnessing the unique power of atom probe microscopy to reveal the NW structure in three dimensions, and at atomic-resolution. The project aims to place Australian research at the frontier of development of these future industries.Read moreRead less
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 develop an efficient multi-scale modelling capability to quantify the effect of two-phase fluid flow within porous material by modelling rock wettability heterogeneity and alteration on two-phase flow performance for heterogeneous rock. Super-resolution methods combined with a deep learning approach will be used to determine a digital representation of reservoir rock, achieving an unprecedented combination of resolution necessary to resolve small-scale fluid connectivity and field of view required to capture heterogeneity. The project expects to develop a workflow to populate a high-resolution model with wettability parameters by combining micro-CT imaging with nuclear magnetic resonance measurements. This improved understanding should provide significant benefits by enhancing our capability to optimise enhanced oil and gas recovery programs.Read moreRead less
