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
Thin Films of Oxide Ceramics. Aluminium oxide films are used extensively in the Australian industries of Protective & Decorative Coatings (examples include door-knobs and cutting-tools). The industry will be offered a remarkably simple process for preparation of high quality films.

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
Helium droplets: a nanoscale laboratory for studying intermolecular bonding and chemical reactivity. This type of research requires a rather complicated apparatus capable of creating a stream of helium droplets, embedding molecules and interrogating their properties using laser spectroscopy. The apparatus built in Sydney is the only one capable of this in Australia and using this new apparatus we will create many novel, bizarre and intriguing aggregates of molecules and atoms.
