The Benefits of Utilising Visual-Spatial Representations of Numbers . The aim of this project is to investigate how visual-spatial representations of numbers enhance practice to promote the use of retrieval-based over counting-based strategies for children learning early arithmetic. About one-third of Australian children stay reliant on counting strategies for basic arithmetic, despite these being associated with lower achievement in mathematics in later years. Expected outcomes of this project ....The Benefits of Utilising Visual-Spatial Representations of Numbers . The aim of this project is to investigate how visual-spatial representations of numbers enhance practice to promote the use of retrieval-based over counting-based strategies for children learning early arithmetic. About one-third of Australian children stay reliant on counting strategies for basic arithmetic, despite these being associated with lower achievement in mathematics in later years. Expected outcomes of this project are new understandings of how problem-answer associations can be strengthened in memory and the development of tools to promote retrieval-based strategies. Potential benefits include children who are better prepared to take on higher-level mathematics in secondary school and, subsequently, more numerate citizens. Read moreRead less
Designer solvents to control reaction outcome. This project aims to control outcomes of chemical reactions using specifically designed ionic liquids as solvents. Ionic liquids are distinct from molecular solvents and are underused due to the limited understanding of their effects on chemical processes. We are developing a predictive framework to explain such effects and this project aims to exploit this new knowledge, using both new and rarely applied ionic liquids to control reaction outcomes. ....Designer solvents to control reaction outcome. This project aims to control outcomes of chemical reactions using specifically designed ionic liquids as solvents. Ionic liquids are distinct from molecular solvents and are underused due to the limited understanding of their effects on chemical processes. We are developing a predictive framework to explain such effects and this project aims to exploit this new knowledge, using both new and rarely applied ionic liquids to control reaction outcomes. The significance lies in the ability to optimise reaction outcomes without the need for solvent screening. The innovation lies in the measurement of microscopic interactions between solvent and reagents, and the use of these interactions to affect a given process.Read moreRead less

Soil communities, among the most abundant and diverse in nature are responsible for many critical ecosystem functions, including nutrient cycling and climate regulation. This project will determine whether consideration and quantification of interactions between different biotic communities – specifically among plants, soil microbes and animals, within and across trophic levels - can address underlying shortcomings in predictions from classical biodiversity-ecosystem function theory. By advancing understanding of biological complexity and its impacts on ecosystem functions, the project will provide a unifying framework for understanding variation in ecosystem functions across scales, ecosystem types and multiple environmental disturbances.Read moreRead less
Examining scientific, philosophical, and folk perspectives on time=. This project aims to consider three very different physical theories, each of which reconciles quantum mechanics and general and special relativity in a different way. While science is more accessible than ever, we are increasingly faced with a scientific world-view that is antithetical to the way we see the world and experience ourselves in it. This project will consider the tension between the scientific picture of the world ....Examining scientific, philosophical, and folk perspectives on time=. This project aims to consider three very different physical theories, each of which reconciles quantum mechanics and general and special relativity in a different way. While science is more accessible than ever, we are increasingly faced with a scientific world-view that is antithetical to the way we see the world and experience ourselves in it. This project will consider the tension between the scientific picture of the world and our experience of the world, and aims to reconcile the two by bridging the gap between lived experience and scientific findings. The project will provide a range of ways of bridging the tension between these physical theories with our lived experience.Read moreRead less
Catalytic conversion of Australia's natural gas to value added products. While natural gas (of which methane is the primary component) is an abundant source of energy, it is normally found in remote areas and for its successful exploitation it needs to be processed. The processing usually requires significant energy and resources input. In this project we will develop a fundamental understanding to a single step catalytic process that can utilise natural gas and nitrous oxide (both potent greenh ....Catalytic conversion of Australia's natural gas to value added products. While natural gas (of which methane is the primary component) is an abundant source of energy, it is normally found in remote areas and for its successful exploitation it needs to be processed. The processing usually requires significant energy and resources input. In this project we will develop a fundamental understanding to a single step catalytic process that can utilise natural gas and nitrous oxide (both potent greenhouse gases) and oxygen to produce selectively methanol and hydrocarbons from a natural gas feedstream in a controlled manner. A single step process for natural gas conversion utilising waste green-house gases is expected to be of great benefit to the Australian economy, environment and energy securityRead moreRead less

The results of this study will help inform publicly funded greenhouse gas abatement strategies, ensuring a maximal return on investment.Read moreRead less
The role of phospholipids in the biogenesis of lipid droplets. The general aim is to elucidate the fundamental molecular mechanisms that govern the biogenesis/formation of the lipid droplets. Lipid droplets store sterol esters and/or triacylglycerols, two major storage lipids that play key roles in cellular and whole body lipid metabolism. Lipid droplets are also the core components of plant oil and biodiesel. Little is known about how lipid droplets are generated. The proposed work will examine ....The role of phospholipids in the biogenesis of lipid droplets. The general aim is to elucidate the fundamental molecular mechanisms that govern the biogenesis/formation of the lipid droplets. Lipid droplets store sterol esters and/or triacylglycerols, two major storage lipids that play key roles in cellular and whole body lipid metabolism. Lipid droplets are also the core components of plant oil and biodiesel. Little is known about how lipid droplets are generated. The proposed work will examine the synthesis of certain lipid intermediates such as phosphatidic acid, and their impact on the biogenesis of lipid droplets from the endoplasmic reticulum. Such fundamental new knowledge on how cells store neutral lipids will provide new strategies for enhancing plant oil and biodiesel production. Read moreRead less
Shallow water carbonate sediment dissolution in the global carbon cycle. Carbonate sediment dissolution is a globally significant process, but poorly understood in shallow marine waters. This project will determine whether the combined effect of organic matter, ocean acidification and pore water flow in shallow water carbonate sediments increases the release of calcium and alkalinity to the ocean. This project is significant because this release has not previously been accounted for and may lead ....Shallow water carbonate sediment dissolution in the global carbon cycle. Carbonate sediment dissolution is a globally significant process, but poorly understood in shallow marine waters. This project will determine whether the combined effect of organic matter, ocean acidification and pore water flow in shallow water carbonate sediments increases the release of calcium and alkalinity to the ocean. This project is significant because this release has not previously been accounted for and may lead to an additional uptake of atmospheric carbon dioxide into the global ocean, maybe some additional buffering against ocean acidification, but unfortunately, maybe also a loss of carbonate ecosystems. The outcomes of this project will make a significant contribution to our understanding of the global carbon cycle.
