The brain dysfunction indicators have been extremely difficult to obtain, largely because many disorders of higher brain function reflect abnormalities of brain function rather than apparent brain structure. The neuronal generator localization and identification in this project will provide complementary information about source and timing of neural activities sub-serving higher brain function and form sequences of spatial-temporal brain activity image. That will enable the information from MRI, which has a good spatial but poor temporal resolution, and the information from EEG, which has a high temporal resolution on the scalp, to be combined to provide clinical psychologists and brain researchers a more efficient diagnostic tool.Read moreRead less

Towards a miniaturised on-chip terahertz biosensing system. Terahertz (or T-ray) radiation is highly sensitive to minute changes in the molecular structure of many substances. Furthermore most packing materials are transparent to this new form of radiation. This implies enormous potential for T-rays in a range of applications from quality control via non-invasive contact-less chemical fingerprinting through to safety and security applications. A detailed study of the molecular vibrations that gi ....Towards a miniaturised on-chip terahertz biosensing system. Terahertz (or T-ray) radiation is highly sensitive to minute changes in the molecular structure of many substances. Furthermore most packing materials are transparent to this new form of radiation. This implies enormous potential for T-rays in a range of applications from quality control via non-invasive contact-less chemical fingerprinting through to safety and security applications.

Techniques for probing biological media with holographic angular scattering spectroscopy. Huge effort in the biological and medical sciences is spent in using simple software to laboriously mark, count and measure cells and structures in microscope images of samples. We could replace this incredibly inefficient process in many instances with single-shot size-map images of unstained samples.

Huge effort in the biological and medical sciences is spent in using simple software to laboriously mark, count and measure cells and structures in microscope images of samples. We could replace this incredibly inefficient process in many instances with single-shot size-map images of unstained samples. If depth selectivity can be added, we could perform non-invasive measurements on animals, making a huge reduction in their usage. We could assess thick tissues enabling early noninvasive diagnosis of malignancy in tumours in situ or muscle characterization for meat quality or muscular dystrophy. These benefits impact on research, animal ethics, and on health, and have commercial potential in life and medical sciences, and the meat industry.Read moreRead less

In Australia, 40%(50,797) of all deaths each year are related to heart disease and accounted for 12% (A$4Billion) of total recurrent health expenditure. This innovative research aims at developing a single biventricular assist device (BVAD) driven by a magnetically suspended double-sided centrifugal pump impeller. Current techniques require two implantable devices, thus preventing smaller patients from access to BVAD technology. The expected outcomes will be a significantly small and compact device and provide an alternative to open-heart transplantation, thus helping to alleviate the demand on donor hearts, as well as the strain on the Australian Heath Care System caused by cardiovascular disease.Read moreRead less
