Novel research based around the Atomic Force Microscope are pursued to make ultra-sensitive measurement of forces between emulsion droplets and probe the mechanical properties of long molecules such as DNA. These studies generate basic knowledge that provides insight about emulsion stability that are of importance from the food and pharmaceutical industries to manufacturing drilling mud for oil wells. The results also provide qualitative and predictive information about the mechanisms that determine the interaction involving large bio-molecules such as DNA and proteins. The instrumentation created along the way has the potential to be developed into special purpose ultra-sensitive devices and sensors.Read moreRead less
Biodegradable polymeric microparticles for targeted delivery. The use of microparticles with tuneable physicochemical properties and loading characteristics is of interest in the fields of biomaterials, drug delivery and imaging. Such engineered particles are likely to address problems associated with conventional drugs and drug carriers, including poor disease site selectivity, polymer toxicity, non-biodegradability and free diffusion of drugs throughout the body.

The overarching goal of this project is to obtain the depth of knowledge necessary to achieve specific size, composition and morphology control in the crystallization of nanometer-sized iron oxides. The project focusses on the structural characteristics of the oxy-hydroxide phase ferrihydrite, which is a key intermediate in the formation of other iron oxides. The project will employ characterization techniques such as small-angle scattering, high resolution TEM, electron nanodiffraction and magnetic energy barrier distribution measurements to study crystallization processes of the iron oxy-hydroxide ferrihydrite, both in vivo and in vitro. The knowledge gained from the biological realm will allow us to devise new laboratory techniques for the preparation of nanoparticles, and provide important information about iron biomineralization to advance the treatment of iron overload diseases.Read moreRead less

Australian Synchrotron Sciences Network. A synchrotron light source is a critical piece of infrastructure for a modern technological nation. In 2001, the Victorian government announced that it would contribute $157M towards the establishment of a national synchrotron facility, becoming operational in 2007. The research performed at such a facility is exceedingly diverse, and often the underpinning technology is the only point of contact for users.

In 2001, the Victorian government announced that it would contribute $157M towards the establishment of a national synchrotron facility, becoming operational in 2007. The research performed at such a facility is exceedingly diverse, and often the underpinning technology is the only point of contact for users. A vibrant and productive facility requires a transparent interface between the scientist and the technology. This Network will set up the communication channels within the user base, and between the users and the facility development program.Read moreRead less
Greatly improved rectification by molecular diodes. Society has already seen dramatic benefits from microtechnology, which has made possible most of the devices that we take for granted. The limits of miniaturisation using current technology are rapidly being reached, and the next stage is in the realm of nanotechnology.

Society has already seen dramatic benefits from microtechnology, which has made possible most of the devices that we take for granted. The limits of miniaturisation using current technology are rapidly being reached, and the next stage is in the realm of nanotechnology. The goal of the field known as molecular electronics is to reach the point where electronic components are composed of single molecules or single molecular layers. In this field the smallest active component is the molecular diode, and this project is focussed on achieving practical performance from molecular diodes, as a crucial first step in achieving miniaturisation far beyond anything now possible.Read moreRead less

Friction and deformation occur from the mutual motion and interaction of microscopic particles and surfaces. This research aims to develop new theories and measurement techniques for these non-equilibrium phenomena by combining mathematical analysis and numerical computations with dynamic force measurement, surface modification, and surface characterisation on nanometre and molecular length scales. These insights and data will be critically important in designing low-friction surfaces that save energy and wear, in developing nanoscopic probes for the mechanical and structural properties of soft polymeric and bio-materials, and in making high performance coatings that control adhesion and particle aggregation in technologically advanced applications.Read moreRead less
