This project will develop novel, state-of-the-art circuits and design strategies that overcome the challenges of current and future Integrated Circuit (IC) fabrication technologies. The extremely small sizes of transistors in these technologies offer advantages in speed, but at the price of a number of drawbacks, which the project will aim to overcome in this work. This research will make a significant contribution to the field of IC design as well as providing training for students to fill the present and future needs of Australia's IC design companies. Some of the most advanced cochlear implants, mobile phone ICs, and Wireless Internet ICs have been designed in Australia, and companies in Australia desperately need graduates skilled in designing in the latest technologies.Read moreRead less
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.

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.

New insights on the role of microalloying in high strength steels. By gaining fundamental understanding of microalloying element interactions at an atomic level during various stages of steel processing, this project aims to assist optimisation of steel compositions and address important industrial issues. Further modifications of the Castrip process of steel strip production will be examined.
Advanced hard metals: microstructure-property-processing relationships. Our aim is to understand the origins of the properties of tungsten-carbide cobalt based hard metals and how these may be tuned via alloying and processing. This is significant because hard metals are used in industrial-scale turning, milling and drilling processes to cut other materials into finished parts with precise tolerance and surface finish. The expected outcomes are increased competitiveness of Australia's aerospace, ....Advanced hard metals: microstructure-property-processing relationships. Our aim is to understand the origins of the properties of tungsten-carbide cobalt based hard metals and how these may be tuned via alloying and processing. This is significant because hard metals are used in industrial-scale turning, milling and drilling processes to cut other materials into finished parts with precise tolerance and surface finish. The expected outcomes are increased competitiveness of Australia's aerospace, agriculture, biomedical, construction, defence, mechatronics, mining, and oil and gas industries, which depend on this materials technology. The benefits will be the creation of leading expertise in advanced manufacturing, support of end-user industries and the establishment of a regional R&D focal point in hard metals.Read moreRead less

Mitigating hydrogen embrittlement in high-strength steels. Hydrogen wreaks havoc in many alloys, leading to embrittlement that can cause catastrophic failure. This is a very serious issue for any industry in which structures are exposed to hydrogen and is a limiting factor for the production, transport, storage and use of hydrogen in a potential hydrogen economy. However, understanding the behaviour of hydrogen in alloys is restricted by the difficulty of observing it. In this project we will ob ....Mitigating hydrogen embrittlement in high-strength steels. Hydrogen wreaks havoc in many alloys, leading to embrittlement that can cause catastrophic failure. This is a very serious issue for any industry in which structures are exposed to hydrogen and is a limiting factor for the production, transport, storage and use of hydrogen in a potential hydrogen economy. However, understanding the behaviour of hydrogen in alloys is restricted by the difficulty of observing it. In this project we will obtain accurate 3D maps showing the position of hydrogen atoms in steel by combining deuteration with cryogenic atom probe microscopy. In this way we will will elucidate how a proposed solution, hydrogen trapping, reduces hydrogen embrittlement, contributing to design criteria for hydrogen-resistant steels.Read moreRead less
