Heat management is critical to many technologies for sustainable energy, electronics, protective equipment and energy-efficient buildings. The phonon is the quantum particle representing a travelling vibration and is responsible for the transmission of heat in solids. This project will study the new mechanisms for phonon transport in solids modified with embedded nanoparticles, which operate as phononic filters. Neutron spectroscopy provides a tool to measure the phonon density of states which is critical for developing a mathematical model of thermal boundary resistance. This is expected to identify mechanisms for ultra-low thermal conductivity leading to potential applications in thermoelectric generators and heat-resistant materials.Read moreRead less

Precipitation in the solid state is key to the performance of many materials, but is especially important for light alloys used in structural applications. This project expects to deliver greater fundamental understanding of precipitation mechanisms and generate experimental and computational methods for three-dimensional characterisation and simulations at the atomic-scale of embedded nanostructures. This should provide significant benefits for the improved design of light alloys, such as for the automotive and aerospace sectors, but also for high-tech materials whose function depends on precipitates.

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

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
