Creating pH-sensitive self-healing concrete using sludge waste for sewers. In Australia, our 117,000 km of concrete sewer pipes are currently internally corroding at a depth rate of 1-3 mm per annum. The repair of deteriorated concrete is costly and often short-lived. Based on an advanced composite technology, this project will develop a pH-sensitive self-healing concrete that can repair itself without human intervention at the early stage of corrosion. Sludge waste from drinking water treatment ....Creating pH-sensitive self-healing concrete using sludge waste for sewers. In Australia, our 117,000 km of concrete sewer pipes are currently internally corroding at a depth rate of 1-3 mm per annum. The repair of deteriorated concrete is costly and often short-lived. Based on an advanced composite technology, this project will develop a pH-sensitive self-healing concrete that can repair itself without human intervention at the early stage of corrosion. Sludge waste from drinking water treatment will be utilised as a healing agent to mitigate the corrosion. Combined experiments and molecular dynamics simulation will uncover all aspects of the healing process to enable the practical application of this technology. The findings will extend the lifetime of concrete structures and promote a circular economy.Read moreRead less

Lactic acid is the most widely occurring multifunctional organic acid. It has enormous applications in food and food-related industries, and great potential use for production of biodegradable and biocompatible polylactate polymers. The aim of this research is to develop an innovative biotechnological process, incorporating simultaneous saccharification and fermentation, which integrates the production of lactic acid with the treatment of high strength food industry ?effluent? streams - carbohydrate waste streams. The proposed SSF process will cultivate an identified fungal Rhizopus sp strain on the waste streams, as production substrates, leading to an environmentally friendly and economically sustainable new technology for the food industry.Read moreRead less

Mimicking peptide structure - towards an aqueous environment. In this proposal we develop a fundamental understanding of the balance between 'weak' and 'strong' forces to define the properties of peptides and proteins. This will allow the design of new biological probes and materials with tailor-made chemical and physical properties for use in bioengineering, biotechnology, proteomics, and drug design. One such example is the design and preparation of a new chemical agent for the non-surgical tr ....Mimicking peptide structure - towards an aqueous environment.

One such example is the design and preparation of a new chemical agent for the non-surgical treatment for cataract, the major cause of blindness world-wide.Read moreRead less
Anomalous interfacial air-bubble dynamics: the importance of electrokinetic effects in thin film drainage. Air bubbles play important roles in numerous systems including plastics and paper recycling, water treatment and mineral separation processes, foodstuffs, beverages, cosmetics, cleaning products, fire retardants, and natural systems such as rivers, oceans and biological fluids. The properties and behaviour of these systems and processes depend on how air bubbles in water interact with each ....Anomalous interfacial air-bubble dynamics: the importance of electrokinetic effects in thin film drainage. Air bubbles play important roles in numerous systems including plastics and paper recycling, water treatment and mineral separation processes, foodstuffs, beverages, cosmetics, cleaning products, fire retardants, and natural systems such as rivers, oceans and biological fluids. The properties and behaviour of these systems and processes depend on how air bubbles in water interact with each other, and/or with other materials. Currently our understanding of the bubble interactions is incomplete. The improved understanding gained from this research project will lead to better ability to control the properties of systems and processes such as those listed above.Read moreRead less

The aim of this project is to develop a sustainable process for producing biodegradable polyhydroxyalkanoate (PHAs)polymers from an innovative aerobic-anaerobic biological wastewater treatment process, ?treating? high strength food industry effluent. These biopolymers offer enormous potential for use as renewable and biodegradable thermoplastics.
It is proposed to investigate two process configurations, namely the sequencing batch reactor and a continuous two step anaerobic-aerobic reaction system. These will be studied at bench-scale. The outcomes include:
1. Determination of the optimum microbial conditions and key growth
parameters for the production of PHA.
2. Optimisation of the process configuration, operating strategies
and operating conditions to maximise the
production of PHA.
3. Assessment of the influence of the feed composition (e.g. VFA)
on the PHA composition (PHB/PHV).

Criminal justice systems have increasingly identified violent offenders as a key target group for rehabilitation programs. Anger management or violence programs have been widely implemented in Australia. However, recent research evaluating program outcomes suggests that the overall impact of these programs is low. The aim of the proposed project is to develop new and more effective interventions for violent offenders by examining the role of perspective taking deficits in angry and violent behaviour. The research will therefore contribute directly to the reduction of violent crime and improved community safety in Australia.Read moreRead less
Understanding and working with anger in male Indigenous people in prison settings. Anger has links to many important outcomes in the prison environment, including violent behaviour, institutional conflict and self-harm. The nature and consequences of anger have rarely been investigated for imprisoned offenders and little is known about anger in male Indigenous Australians in prison, despite evidence that anger levels in this group are particularly high.

Anger has links to many important outcomes in the prison environment, including violent behaviour, institutional conflict and self-harm. The nature and consequences of anger have rarely been investigated for imprisoned offenders and little is known about anger in male Indigenous Australians in prison, despite evidence that anger levels in this group are particularly high. This research will explore constitutive, regulatory, procedural and other aspects of anger with male Indigenous prisoners, using both qualitative and quantitative methodologies, leading to the development of an intervention that will improve both the wellbeing and adjustment of Indigenous men in prison and rehabilitation outcomes.Read moreRead less
