Chlorine Evolution Catalysts for Efferent Seawater Electrolysis. Seawater is the most abundant aqueous resource on earth that is readily accessible at very low costs, but yet to be directly utilised for production of hydrogen fuel and commodity chemicals.

Seawater is the most abundant aqueous resource on earth that is readily accessible at very low costs, but yet to be directly utilised for production of hydrogen fuel and commodity chemicals. This project aims to develop cheap and plentiful carbon-based high performance chlorine evolution electrocatalysts for seawater electrolysis powered by renewable electricity to realise the production of hydrogen, chlorine and sodium hydroxide directly from seawater. The electrolyser can also be used to treat desalination brine while produce hydrogen and chemicals. The success of the project will set a firm technological foundation for seawater utilisation, which will add to Australian capability to meet future energy and environment challenges.Read moreRead less

Summary
Investigation and development of biological anti-adhesive coatings. Lubricin is a biological anti-adhesive protein that is found in mammalian joints. This project will investigate the properties and action of Lubricin and develop novel anti-adhesive coating technologies to eliminate problems associated with non-specific binding of biomolecules in microfluidic and biosensor applications.
Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the cr ....Regulation of 3D Cell Migration by Microtubule-Dependent Processes. The overarching aim of this research is to elucidate the molecular mechanisms that cells use to move in 3D environments: a basic biological function essential to development and homeostasis. During these processes, cells interact with their surroundings where they translate biophysical forces into biochemical signals to adapt their shape to move. This requires distinct signalling, controlled in space and time, to regulate the crosstalk between organelles and the cytoskeleton. To date, the role of microtubules remains elusive. Using interdisciplinary approaches combining advanced imaging technology with novel cell biology methods, the project aims to uncover fundamental knowledge about how cells interact with their environment.Read moreRead less
Using lasers to prime the immune system. This project aims to detail the precise effects that lasers have on eye cells, cell populations and the body as a whole. Laser treatments for sight problems are increasing but the effects of these laser applications on the unique immune systems of the eye and brain are unknown. Previous work of the researchers has shown that a novel nanosecond laser when targeted to the eye can alter cells in the lasered eye and in the unlasered eye and the brain.

Laser treatments for sight problems are increasing but the effects of these laser applications on the unique immune systems of the eye and brain are unknown. Previous work of the researchers has shown that a novel nanosecond laser when targeted to the eye can alter cells in the lasered eye and in the unlasered eye and the brain. This knowledge may be crucial for enhancing our understanding of the immune privileged state of the eye. In addition, it seeks to guide the development of future low energy lasers as important successful treatments.Read moreRead less

This project aims to determine the underlying mechanisms by which DNA and other molecules are able to migrate across the cell membrane in response to highly localised electric fields. It has recently been shown that focusing of electric fields at the cellular level, using an array of small electrodes, results in unexpectedly high cell transfection efficiencies. It has been termed 'close-field electroporation'. Here it is proposed to establish the properties of the electric fields around cells and cell membrane interactions with these fields that enable molecular translocation. This fundamental science could have broad implications in the domains of drug delivery, gene therapy and neural stimulation.Read moreRead less
