Stronger, coarser-grained biodegradable zinc alloys. This project aims to develop stronger and more durable zinc alloys for a new generation of biodegradable metals for potential load-bearing orthopaedic applications. It expects to deliver a group of novel zinc alloys with better properties and a new technology for manufacturing them, and to use advanced experimental techniques to reveal deformation and strengthening mechanisms that underlie the unusual Hall-Petch and anomalous twinning phenomen ....Stronger, coarser-grained biodegradable zinc alloys. This project aims to develop stronger and more durable zinc alloys for a new generation of biodegradable metals for potential load-bearing orthopaedic applications. It expects to deliver a group of novel zinc alloys with better properties and a new technology for manufacturing them, and to use advanced experimental techniques to reveal deformation and strengthening mechanisms that underlie the unusual Hall-Petch and anomalous twinning phenomena and the unprecedented properties of these alloys. Expected outcomes are likely to form the technology and scientific basis for developing better biodegradable metallic alloys. This has the potential eventually to create a better life for thousands of Australian patients.Read moreRead less
Stronger zinc alloys for more flexible biodegradable stents. This project aims to develop stronger zinc alloys for a new class of biodegradable metallic stents. A key challenge for biodegradable stent technology is to make stents as thin as possible while also being strong. This project will develop ultra-high strength zinc alloys that can be used to fabricate thinner biodegradable stents for easier surgical operation. The project outcomes should be a major step in the design and development of ....Stronger zinc alloys for more flexible biodegradable stents.

Oxygenation history of the Earth and the evolution of complex life. This project will investigate how and when the atmosphere became oxygen-rich by analyzing ancient barrier reefs and other rocks that formed between 1000 to 300 million years ago, spanning the appearance and diversification of animals and plants. The project is significant because the buildup of oxygen in the atmosphere was arguably the most important chemical process ever to have occurred on Earth and controlled the evolution of ....Oxygenation history of the Earth and the evolution of complex life. This project will investigate how and when the atmosphere became oxygen-rich by analyzing ancient barrier reefs and other rocks that formed between 1000 to 300 million years ago, spanning the appearance and diversification of animals and plants. The project is significant because the buildup of oxygen in the atmosphere was arguably the most important chemical process ever to have occurred on Earth and controlled the evolution of environments, climate and life. A major outcome will be an improved understanding of how the Earth's atmosphere and climate are regulated by geological processes. This project will generate new knowledge about how sedimentary zinc, lead and copper ore deposits form, which may guide exploration for these commodities.Read moreRead less
