The Interface of Oil-in-Water Emulsions. The interface between two immiscible liquids controls many phenomena including the formation and properties of emulsions, the nature of many chemical separation processes and the behaviour of biological systems. There are few methods to study such interfaces and most of these are susceptible to trace contamination by adventitious surfactants, but emulsions with their large surface area avoid this problem. Significant advances are possible with the new Aus ....The Interface of Oil-in-Water Emulsions. The interface between two immiscible liquids controls many phenomena including the formation and properties of emulsions, the nature of many chemical separation processes and the behaviour of biological systems. There are few methods to study such interfaces and most of these are susceptible to trace contamination by adventitious surfactants, but emulsions with their large surface area avoid this problem. Significant advances are possible with the new Australian technique of electroacoustics, complemented by neutron scattering, nmr, rheological and dielectric response measurements on concentrated emulsions. Our surfactant-free emulsions provide a fundamental breakthrough in such studies, leading to new materials from nanostructures.Read moreRead less

Improving explosive emulsions by understanding surfactant interactions. This project will design new surfactants that will lead to more cost effective, stable and reliable explosive emulsions. The pressure required to force dispersed phase droplets to coalesce will be measured both directly and by osmotic stress. These parameters have not previously been measured for an inverse emulsion system. The measurements made will be correlated to the structure of the stabilising surfactant enabling new a ....Improving explosive emulsions by understanding surfactant interactions.

Bubble Stabilization and Density Control in Self-Supporting Explosive Emulsions. The mining industry in Australia employs about 70,000 people and has a total sales and service income of about $55B. Most mining outputs are commodities and a reduction in cost is the primary method of increasing market share. DNAP is a major supplier of explosive services to mines that produce coal, iron ore and gold for export.

The mining industry in Australia employs about 70,000 people and has a total sales and service income of about $55B. Most mining outputs are commodities and a reduction in cost is the primary method of increasing market share. DNAP is a major supplier of explosive services to mines that produce coal, iron ore and gold for export. The work in this project will lead to more efficient explosives emulsions and allow mining tolower total cost per unit sold. Such improvements in mining efficiencies will have a direct impact of the selling price of the product. Increased export earnings and a greater number of people employed in the industry would be direct results of the successful completion of the work proposed.Read moreRead less
Nanoparticles with designed morphology for surface-coating applications. Significantly improved water-based paints, with zero volatile organic content and organic opacifiers, are highly desirable for environmental and health reasons. The science needed to produce such paints has been persistently elusive. USyd and Dulux will collaborate to achieve these paints by using Australian-developed platform technologies that allow polymer architecture to be controlled at molecular and nanoscale levels.

Significantly improved water-based paints, with zero volatile organic content and organic opacifiers, are highly desirable for environmental and health reasons. The science needed to produce such paints has been persistently elusive. USyd and Dulux will collaborate to achieve these paints by using Australian-developed platform technologies that allow polymer architecture to be controlled at molecular and nanoscale levels. This will give us the means to make structured nanoparticles with morphologies that had been regarded as unachievable, and that are the key to dispensing with harmful ingredients in paints.Read moreRead less
Template-Free Synthesis of Zeolite Nanocrystals and Their Application for Zeolite-Polymer Nanocomposites. A novel method is proposed for template-free synthesis of zeolite nanocrystals, in which polymer hydrogels will be used, in-situ, to control zeolite nucleation and growth from precursor solutions.

What controls the shift from a hot house climate to a cold house climate: the Eocene/ Oligocene climate transition and greenhouse warming. This study contributes to putting Australia on the map as a centre of excellence in the study of past climates as well as in global warming research. It aims at a greater understanding of the dynamics of past warm climate states. This could ultimately lead to a better knowledge of the formation of the ancient deposits that we mine in Australia today.

This study contributes to putting Australia on the map as a centre of excellence in the study of past climates as well as in global warming research. It aims at a greater understanding of the dynamics of past warm climate states. This could ultimately lead to a better knowledge of the formation of the ancient deposits that we mine in Australia today. Furthermore, the study of these past warm climates tells us something about current global warming as both involve increased levels of carbon in the atmosphere. The impact of climate change on Australia is likely to be large. Our study of past warm climates helps to gain an understanding of the mechanisms behind climate change and help quantify the risks of climate change posed to Australia.Read moreRead less

The ability to accurately establish the identity of an individual is central to the national security of Australia. Identity checking often relies on facial photographs contained on passports and other documents. Despite the introduction of automated systems, the decision whether a photograph is of a person rests with human operators. Research by CI has demonstrated that this task is difficult and error prone. The proposed research seeks to improve performance by developing a fuller understanding of the nature of the task and the limits of the operators' abilities and by testing possible training and selection procedures.Read moreRead less
