ARC Centre of Excellence for Green Electrochemical Transformation of Carbon Dioxide.- CE230100017ARC Centre of Excellence for Green Electrochemical Transformation of Carbon Dioxide. ARC Centre of Excellence for Green Electrochemical Transformation of Carbon Dioxide. This Centre aims to advance carbon dioxide electrochemistry innovations to enable the conversion of carbon dioxide into valuable products and transition Australia to a carbon-neutral economy. This Centre expects to generate new knowledge using experimental and computational approaches to develop systems-level understanding to furnish industry-ready carbon dioxide utilisation technologies. Expected outcomes include enhanced capacity through collaborations establishing the Centre as an international hub for research, training, technology translation and strategic advice for stakeholders and policymakers. This should accelerate Australia’s progress towards net zero emissions targets and grow a sustainable economy and create future jobs.2023
ARC Linkage Projects LP190101279 Enabling Next-generation Rechargeable Aluminium-ion Batteries. This project aims to develop a new generation of high performance and low-cost cathode materials for rechargeable aluminium ion batteries. To address the low capacity issue of current cathodes, this project anticipates to generate new knowledge in the material design of novel graphene materials. By developing an innovative surface perforation technique coupled in a continuous production process, this project expects to produce scalable and cost-effective graphene cathodes with a record-high capacity. Expected outcomes of this project include industrial adaptable manufacturing processing and advanced materials for aluminium ion batteries, thus increasing the competitiveness of the partner organisation in the rapid growing graphene market.2021
ARC Research Hub for Advanced Manufacturing with 2D Materials (AM2D). IH210100025 ARC Research Hub for Advanced Manufacturing with 2D Materials (AM2D). Australia holds large resources of critical 2D minerals – key enablers of several existing and emerging technologies in Energy Storage, Purification and Printed Electronics. The AM2D hub aims to provide a sophisticated environment for researchers and an industrial translation platform for manufacturers; a hub where leading academics, bright students, and industry partners come together to learn, apply, collaborate, innovate, and deliver industry transformation in advanced manufacturing. Anticipated outcomes include the transformation of newly discovered materials into globally traded, high-value 2D products, enabling Australian industries to capture more wealth and jobs from this large and growing market.2021
ARC Linkage Projects LP190100830 Developing high performance nanocomposite coatings for domestic appliances. Insufficient robustness and durability of the polymeric coatings on precoated metal sheets has resulted in unacceptably high product defects and reject rates. This project aims to develop novel and high performance nanocomposite multilayer coatings through the systematic optimisation of epoxy and polyester/ graphene and nanoclay systems. These complex coatings are expected to have considerably improved toughness, hardness and interfacial adhesion, thus enhancing formability and wear resistance of precoated metal sheets. Successful outcomes from this study will not only solve a long-standing problem in the manufacturing of precoated metals, but generate breakthrough technologies for next-generation nanocomposite coatings.2020
