Designer Surfactants for Creation of Emulsion Properties. We propose new approaches to the design of surfactants for stabilising water in oil emulsions. New block copolymer surfactants may be "tailored" for head group structure and a pre-chosen hydrophilic/lipophilic balance at the oil-water interface using the Australian developed RAFT polymer synthesis method and polymeric inorganic species. The proposers have an extensive background in these areas.

X-ray and neutron scattering techniques, developed by us, allow the interfacial structure of the surfactant to be found and the intellectual "loop" closed in the design process. Preliminary screening will be done using the surface balance and bulk emulsion synthesis.Read moreRead less
High Internal Phase Emulsions - Structure and Rheology Control. Our first SPIRT Grant with ORICA Australia Ltd has successfully identified nanostructures in high internal phase emulsions which confer useful stability and robustness on these industrially important systems. The aim now is to ramify those discoveries both scientifically and technologically in the design of emulsion structure using our, now established, techniques. In particular, the objective is to control both nanoscale and mes ....High Internal Phase Emulsions - Structure and Rheology Control. Our first SPIRT Grant with ORICA Australia Ltd has successfully identified nanostructures in high internal phase emulsions which confer useful stability and robustness on these industrially important systems. The aim now is to ramify those discoveries both scientifically and technologically in the design of emulsion structure using our, now established, techniques. In particular, the objective is to control both nanoscale and mesoscale structure in emulsion formulation, as well as the rheology and stability of emulsion preparations. To do this we plan to use mixed surfactant systems and to study intersurfactant synergic effects on the structure and fluidity of the interfacial material. We believe that the proposed work is unique and that the outcomes will be scientifically novel and also valuable for Australian industry.Read moreRead less
Milk protein denaturation and stabilisation at surfaces. The Australian Dairy Industry, valued at $2.8 billion in 2003-4, is ranked third among rural industries in Australia. Australia exports over 50% of its annual milk production, contributing to 13% of world trade. Exports of dairy products are valued at $2.4 billion. In order for Australia to maintain this position, Australia needs to keep up with its major competitors by ensuring quality and consistency of dairy products is maintained, and ....Milk protein denaturation and stabilisation at surfaces.

Australia exports over 50% of its annual milk production, contributing to 13% of world trade. Exports of dairy products are valued at $2.4 billion. In order for Australia to maintain this position, Australia needs to keep up with its major competitors by ensuring quality and consistency of dairy products is maintained, and by developing new applications and innovative products. The proposal expects to recruit an exceptional young Australian graduate - a former Rhodes Scholar from Oxford University.Read moreRead less
Researching the Social Role of Religions in Australia. Most Australians claim allegiance to various religions in the Census. The number of religious denominations has greatly increased in recent years, most notably through immigration, with significant numbers from all world religions. Political and social policies are frequently influenced by religious principles and a detailed analysis of this variety is of crucial national importance. Religions from neighbouring societies are significantly r ....Researching the Social Role of Religions in Australia. Most Australians claim allegiance to various religions in the Census. The number of religious denominations has greatly increased in recent years, most notably through immigration, with significant numbers from all world religions. Political and social policies are frequently influenced by religious principles and a detailed analysis of this variety is of crucial national importance. Religions from neighbouring societies are significantly represented in Australia. Understanding them is of central importance in international political and commercial activity. Current research is essential, based on the most recent Census and other recent socio-economic information.

What makes for successful numeracy education in remote Indigenous contexts: an ethnographic case study approach. There are many successful teachers and schools who have enabled remote Indigenous learners to engage with, and learn, school mathematics. But what do they do? How do they do it? This project investigates and documents successful practices in 32 schools located in remote communities. The project includes the many aspects of teaching practice.
The endangered swift parrot as a model for managing small migratory birds. Endangered swift parrots use variable locations while breeding in eastern Tasmania and over winter on the Australian mainland. This project aims to develop effective conservation strategies for swift parrots and other migrants using new and long term data and innovative technological solutions to tracking small birds across vast landscapes.
Processing mathematics tasks: the nature and role of visual and non-visual reasoning in digital and non-digital environments. Within the next four years, it is likely that the National Assessment Plan for Literacy and Numeracy (NAPLAN) will be administered in a digital mode.

Processing dynamic graphics: Visuospatial reasoning in mathematics. Increasingly, mathematics competence will be measured in digital and dynamic contexts. Students who possess high visuospatial reasoning are expected to become even better equipped to succeed in science, technology, engineering and mathematics (STEM) related disciplines as technological advances shape how we interpret and decode information.

Increasingly, mathematics competence will be measured in digital and dynamic contexts. Students who possess high visuospatial reasoning are expected to become even better equipped to succeed in science, technology, engineering and mathematics (STEM) related disciplines as technological advances shape how we interpret and decode information. This project explores those aspects of visuospatial reasoning critical for success when students encounter dynamic mathematics tasks, and attempts to determine whether different forms of visuospatial reasoning are required to decode static and dynamic information. The project aims to better understand how students process mathematics tasks, so the inevitable move toward digital assessment can be managed effectively to promote assessment for learning.Read moreRead less
Genetic rescue of Australian wildlife. Genetic rescue of Australian wildlife. This project aims to test genetic rescue as an efficient recovery technique for threatened plants and animals. Genetic rescue is under-utilised, even though it is overwhelmingly beneficial. This project will convert management actions on five Endangered/Critically Endangered species into rigorous experiments that measure the fitness benefits of genetic rescue, and demonstrate genome-wide consequences. Anticipated outco ....Genetic rescue of Australian wildlife. Genetic rescue of Australian wildlife. This project aims to test genetic rescue as an efficient recovery technique for threatened plants and animals. Genetic rescue is under-utilised, even though it is overwhelmingly beneficial. This project will convert management actions on five Endangered/Critically Endangered species into rigorous experiments that measure the fitness benefits of genetic rescue, and demonstrate genome-wide consequences. Anticipated outcomes include innovative genetic rescue protocols, a framework for genetic rescue, and leading-edge conservation training. Expected benefits are increased persistence of species that are otherwise unresponsive to management, and a new path to saving endangered species.Read moreRead less
Social and geographical location and its impact on mathematics teaching and learning. Too many students from poor urban backgrounds or from rural communities are at risk of underperforming in school mathematics. This project identifies the critical factors that contribute to this failure and seeks to develop improved practices to enable greater access to school mathematics.
