This project aims to develop a novel, computationally-based framework to optimally and efficiently design new fibre materials based on the diamond nanothreads synthesized by the PI in 2014. The CIs (and others) have demonstrated the tremendous promise these materials hold to replace common carbon fibres. The proposed framework will combine advanced computer modelling, statistical learning, genetic algorithm-based optimal design and experimental validations. It will accelerate the design of these new carbon-based fibres as game-changing materials in a wide range of areas. Ultimately this project has the potential to deliver significant economic benefits and will place Australia at the forefront of the industrial revolution of the future.Read moreRead less
Dislocation motion and anelastic recovery in layered ceramic titanate. This project aims to research deformation and facture in brittle ceramic nanowire materials and anelastic behaviour in tensile deformation.

This project aims to research deformation and facture in brittle ceramic nanowire materials and anelastic behaviour in tensile deformation. Layered sodium titanate is used in energy storage and water treatment, but in-situ tensile tests have observed unconventional deformation behaviour, with significant dislocation motion and anelastic recovery. This project will study the deformation mechanism in layered sodium titanate nanowires through molecular dynamics simulations, empirical interatomic potential, and in situ TEM experiments. Expected outcomes include knowledge of the deformation mechanism of this layered titanate which can be broadened to technologically important layered ceramic materials.Read moreRead less

Probing interfacial impedance in all-solid-state lithium-ion batteries. This project aims to investigate the mechanism behind the high impedance at the interface between electrodes and the solid electrolyte in solid-state lithium-ion batteries using advanced in-situ transmission electron microscopy.

This project aims to investigate the mechanism behind the high impedance at the interface between electrodes and the solid electrolyte in solid-state lithium-ion batteries using advanced in-situ transmission electron microscopy. The outcomes will deepen knowledge in chemical and structural evolution at the electrode–electrolyte interface during battery operation under different conditions, and thus inform the design and fabrication of safe, high power, and long lasting solid-state batteries for a myriad of portable electronic devices and the emerging electric vehicles.Read moreRead less
Plastic deformation and failure of high strength rail steels in heavy haul transportation of mineral products. The Australian Government has made infrastructure, including rail, as a national priority for investment to meet the freight transport demand. This project focuses on the deformation and failure of rail in heavy haul lines to transport ores in the mining industry. The outcomes will be applied to ensure the structural integrity of rail infrastructure.
Mass transport in high entropy alloys. This project aims to understand mass transport in high entropy alloys. Alloys of 5 to 13 components have technologically attractive mechanical properties.

Using 3D printing technology to develop architecturally-controlled synthetic bone substitutes. With the ageing population, there is increasing demand for synthetic materials that can regenerate bone. However, purely synthetic bone-substitute biomaterials cannot regenerate large bone defects in weight-bearing conditions due to their fragility.

With the ageing population, there is increasing demand for synthetic materials that can regenerate bone. However, purely synthetic bone-substitute biomaterials cannot regenerate large bone defects in weight-bearing conditions due to their fragility. This project aims to develop a customisable, biodegradable, biocompatible and mechanically strong and tough scaffold that overcomes this long-standing problem. The project aims to achieve this by applying an innovative combination of cutting-edge 3D printing technology, advanced computational modelling and design techniques to produce a next-generation bioceramic scaffold with optimised architecture. This approach aims also to enable the possibility of producing custom-made implants for individual requirements.Read moreRead less

Intravascular stents are a class of lifelong micro-devices to support blood vessel for restoring circulation. Despite its remarkable initial outcome, the high rate of long-term mechanical failure remains a major concern. This project will tackle plasticity, fatigue damage and fracture across different length scales. The proposed optimisation is expected to minimise failure, thereby enhancing the longevity and reliability of stent therapy. This will have significant benefits, such as accommodating variations in stents and service conditions for achieving a long-lasting and reliable therapeutical outcome.Read moreRead less
