The micro-mechanical origins of creep in granular materials. Creep in granular materials is a concern for many problems in technology and science, including long-term deformations of reservoir dams and sudden instabilities along earthquake faults. This project aims to describe the fine-scale origins of granular creep, as a basis for solving problems of much larger-scale in geomechanics and geophysics.

Summary
Virtual reality for planning of green urban water infrastructure. This project aims to research the planning-technical-social dynamics of Water Sensitive Urban Design (WSUD) infrastructure. WSUD management has become financially and logistically unsustainable due to major urban growth and a rapid uptake in WSUD assets. Solving this problem is, however, complex, as stakeholders have conflicting needs and tacit knowledge that is difficult to quantify. Using emerging virtual reality technology, par ....Virtual reality for planning of green urban water infrastructure. This project aims to research the planning-technical-social dynamics of Water Sensitive Urban Design (WSUD) infrastructure. WSUD management has become financially and logistically unsustainable due to major urban growth and a rapid uptake in WSUD assets. Solving this problem is, however, complex, as stakeholders have conflicting needs and tacit knowledge that is difficult to quantify. Using emerging virtual reality technology, participatory planning and operational models, this project intends to improve WSUD modelling science through integrated modelling. The anticipated outcome is more holistic and economically efficient planning of WSUD layouts in future cities. This is expected to address growing concerns about adequately managing these systems and ensure that they deliver intended environmental protection, liveability and public health benefits.Read moreRead less

Nanoparticle with Metal Organic Framework for Lithium Recovery from Brine. The project aims to develop technology enabling lithium to be cost-effectively extracted from brine. Today Australia meets the increasing demand for lithium by mining hardrock lithium, an environmentally damaging activity. An alternative is to source lithium from brine produced as industrial wastewater (in desalination or shale gas production). The main challenge that brine presents to selectively extracting lithium is co ....Nanoparticle with Metal Organic Framework for Lithium Recovery from Brine. The project aims to develop technology enabling lithium to be cost-effectively extracted from brine. Today Australia meets the increasing demand for lithium by mining hardrock lithium, an environmentally damaging activity. An alternative is to source lithium from brine produced as industrial wastewater (in desalination or shale gas production). The main challenge that brine presents to selectively extracting lithium is competing ions. By advancing knowledge of nanomaterials and membrane distillation, the project expects to overcome both this technical challenge and other practical challenges. From wastewater, the anticipated system will produce additional clean water and a valuable commodity that can offset the cost of water treatment. Read moreRead less
Biosolid flow, separation and activity in anaerobic lagoons. This project aims to develop a fundamental model of the complex, non-steady state flow behaviour in anaerobic lagoons. The project will develop new operating procedures and designs for large municipal, industrial and agricultural anaerobic lagoons.

Algal control using multi-functional, cold plasma activated microbubbles . 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.

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

This project expects to transform the understanding of granular materials and their behaviour by establishing explicit links between the macroscopic responses of the materials and their evolving microstructural properties. This should lead to revolutionary constitutive models for granular materials that possess true mechanisms of evolving grain-scale structures. The proliferation of these new models should allow development of reliable predictive computational tools for the modelling and assessment of field-scale failure involving granular materials, enhancing the capability to assess the integrity and stability of earth structures, and benefitting the Australian economy, environment and public safety.Read moreRead less

Internal soil erosion is the most frequent cause of failures of water retaining structures. An approach combining advanced X-ray techniques with particle based methods will be developed to observe, analyse and link different material properties and external conditions governing the erosion process. This will lead to better criteria for soil erosion and numerical tools for field scale failure analysis and risk assessments. The expected outcomes of this project include enhanced capability to assess the integrity and stability of earth structures and better design criteria against erosion.Read moreRead less
