This project aims to develop a fundamental understanding at the nanostructural level of the factors that contribute to the enhanced mineralisation and mechanical properties of dentine and enamel following the treatment with silver diammine fluoride (SDF). A variety of advanced nanomechanical, tomographic and microscopic techniques will be used to characterise sound, carious and SDF treated tissue. The new biomechanical evidence on the underlying mechanisms, alternative protocols, delivery systems enable to optimise the treatment. The scientific insights into arresting/repairing damage processes will provide critical data for developing minimal intervention protocols for pediatric and geriatric populations.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
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
