Nano-scale modification of gold surfaces for sensing mercury from gaseous effluents of alumina refineries. The Australian alumina industry contributes more than $5.4 billion export income annually. It is also a major driver of the rural economy with all but one of Australia's seven alumina refineries located in rural areas.

The Australian alumina industry contributes more than $5.4 billion export income annually. It is also a major driver of the rural economy with all but one of Australia's seven alumina refineries located in rural areas. In response to the industry's attempts to reduce the environmental impact of its processes, this project will conduct basic strategic research into the interaction between mercury vapour and gold surfaces at the nano-level. Our principal aim is to develop mercury sensor technology suited to alumina refineries. This innovative technology will be a significant breakthrough in the control of mercury emissions and have many other applications.

Calibration Free Coulometric Sensors Based on Polymeric Thin Layer Films. The world faces enormous environmental and clinical challenges that require accurate data from remote deployable and disposable sensors. Many key parameters important to global warming (carbon dioxide cycle) and clinical diagnostics (blood electrolytes) may be assessed with a polymeric membrane sensing technology, but the measurement principle is not sufficiently robust for remote sensing applications. This research will m ....Calibration Free Coulometric Sensors Based on Polymeric Thin Layer Films. The world faces enormous environmental and clinical challenges that require accurate data from remote deployable and disposable sensors. Many key parameters important to global warming (carbon dioxide cycle) and clinical diagnostics (blood electrolytes) may be assessed with a polymeric membrane sensing technology, but the measurement principle is not sufficiently robust for remote sensing applications. This research will make this possible by adapting calibration free measurement principles (coulometry, or charge counting) to this class of sensors, where a thin layer of sample solution will be depleted by instrumental control. This forms the scientific basis for successfully tackling the measurement challenges of the future.Read moreRead less
Computer simulation of DNA biochips. The DNA biochip technology has been a major breakthrough in cell biology and clinical analysis. Companies in Australia and in the rest of the world are now developing biochips for genome sequencing and point-of-care diagnosis. DNA biochips have the potential to provide simple, fast and accurate clinical analysis, thus enhancing the efficiency of medical treatments and reducing the costs of health care.

Companies in Australia and in the rest of the world are now developing biochips for genome sequencing and point-of-care diagnosis. DNA biochips have the potential to provide simple, fast and accurate clinical analysis, thus enhancing the efficiency of medical treatments and reducing the costs of health care.
The structural properties of the immobilized DNA are critical for determining the DNA chip sensitivity and efficiency. A fundamental understanding of the molecular interactions at the surface of a biochip is therefore not only relevant for the scientific community, but can have direct implications for the design of improved DNA chips.Read moreRead less
