Nanostructure Tailoring of Inorganic Membranes by Rapid Thermal Processing. This project aims to produce inorganic membranes with desired nanostructures using a Rapid Thermal Processing (RTP) technique for gas separation applications. The key concept of the research is that the RTP will be able to achieve thin-film membrane layer with a finer microstructure and pore size control without heat stress-induced cracking.

This project aims to produce inorganic membranes with desired nanostructures using a Rapid Thermal Processing (RTP) technique for gas separation applications. The key concept of the research is that the RTP will be able to achieve thin-film membrane layer with a finer microstructure and pore size control without heat stress-induced cracking. RTP aims to deliver superior membrane performance with less than 10 per cent of the fabrication time compared to normal slow calcination. The outcomes of this new technology aims to make inorganic membranes a commercial reality and maximize the membrane manufacturing capability and productivity of petrochemcial, chemical and clean coal/energy industries.Read moreRead less
Speech recognition adaptation for low resource populations. Automatic speech recognition is an essential attribute of mobile devices and consumer electronics. Unfortunately, as these systems are trained with adult speech, they perform poorly when used by children and people with speaking difficulties. The lack of available training speech from these groups makes developing models for them difficult. We will investigate efficient model adaptation methods that use minimal training data to adapt ex ....Speech recognition adaptation for low resource populations. Automatic speech recognition is an essential attribute of mobile devices and consumer electronics. Unfortunately, as these systems are trained with adult speech, they perform poorly when used by children and people with speaking difficulties. The lack of available training speech from these groups makes developing models for them difficult. We will investigate efficient model adaptation methods that use minimal training data to adapt existing adult speech recognition models for use with children and people with speaking difficulties. The intended outcomes will improve access to automatic speech recognition systems for Australians whose communication with speech-controlled environmental and educational devices is currently restricted.Read moreRead less

Climate change is driving a proliferation of nuisance and harmful algal blooms in our water supply systems, which urgently require cost efficient and effective control strategies. Paradoxically, algal biotechnology is a growth industry with application in food, agriculture and energy; realising this potential requires state-of-the-art technology to optimise production, harvesting and extraction. The aim of this proposal is to develop cutting edge technology that uses cold plasma activated microbubbles to control algal populations. We propose that by tuning the plasma composition, this technology could both selectively disrupt and destroy algal matter and enhance algal cell growth, benefiting both water and biotechnology industries.

This project aims to develop a microbial self-healing bio-concrete to extend the service life of wastewater collection and treatment facilities. Water utilities worldwide struggle with asset management, because global warming and extreme weather age and corrode concrete infrastructure. This project will use microbially-induced calcium carbonate precipitation by bacteria to treat wastewater. The bacteria, added to bio-concrete, can fill cracks or reseal corroded areas by using organic substrates from wastewater to generate concrete, thus maintaining structural strength and preventing further damage. This project is expected to enhance the resilience and sustainability of wastewater infrastructure in ever more demanding environments.Read moreRead less

The project aims to develop better mixing theories to support industrial applications. Effective mixing of granular materials such as aggregates in building industry and stockpiles in mineral processing is important for creating homogeneous products, yet industrial mixers lack scientific design and operate with no control of mixture quality. The project aims to establish a new general continuum mixing theory, which will be validated against X-ray measurements of grain motions within small mixers. By describing the theory using an accurate computational method, the simulations of these mixers will be scalable, and would help deliver predictions for particle mixing in much larger operations. Other expected outcomes are to control mixture quality and reduce industry reliance on costly and time-consuming trial-and-error experiments.Read moreRead less
