High-order conservative multiscale computation of elliptic problems in composite materials and porous media. The proposed technology will improve the design and performance of a wide range of mechanisms and industrial processes involving heterogeneous media, from composite materials to water filtration and recycling. Our researchers in computational mechanics will gain further opportunities to extend the advances this project will make.
Surface tension-confined microfluidics: moving towards a flexible platform for diagnostics. The point-of-care industry is poised to fulfil the international need for effective and mobile diagnostics tools; however current strategies are restricting this from becoming a reality. Surface tension-confined microfluidics provide an opportunity to meet the requirements necessary for flexible platform for point-of-care devices.
Energy dissipation and vibration-assisted self-healing in structures with topological interlocking. High dissipation of impact and vibration energy, vibration-assisted self-healing, high tolerance to block failure and an ease of assembly/disassembly make topological interlocking structures ideal for safety barriers, protective shields and floating structures. The theory of these phenomena will open a way for more efficient protection of infrastructure against both natural and human perpetrated i ....Energy dissipation and vibration-assisted self-healing in structures with topological interlocking. High dissipation of impact and vibration energy, vibration-assisted self-healing, high tolerance to block failure and an ease of assembly/disassembly make topological interlocking structures ideal for safety barriers, protective shields and floating structures. The theory of these phenomena will open a way for more efficient protection of infrastructure against both natural and human perpetrated impacts and for developing new methodology in constructing mobile marine bases. This constitutes the main benefit of the project. Furthermore, understanding the resonance structure of travelling waves will improve methods of non-destructive monitoring by back analysing spectral signatures of the waves.Read moreRead less
Self-heating of porous lignocellulosic and coal particles. This project develops models for spontaneous heating of materials, which have substantial value to Australian economy, and whose self-heating behaviour have led to loss of life and significant material losses in industries processing these materials. The results will be immediately applicable to evaluate risks of spontaneous ignition in process plants in a more rigorous manner than performed presently. Furthermore, findings of this inv ....Self-heating of porous lignocellulosic and coal particles. This project develops models for spontaneous heating of materials, which have substantial value to Australian economy, and whose self-heating behaviour have led to loss of life and significant material losses in industries processing these materials. The results will be immediately applicable to evaluate risks of spontaneous ignition in process plants in a more rigorous manner than performed presently. Furthermore, findings of this investigation will allow considerable improvement in estimating green house gas emissions as a consequence of spontaneous combustion.Read moreRead less
Fundamental Fire Properties From Extinction and Piloted Ignition Experiments of Solid Fuels. Current approval methods for determining fire properties of construction materials are often incorrect in yielding properties that can be used in situations removed from test conditions. The main aim of this project is to obtain fundamental fire properties by examining the ignition and extinction processes of diffusion flames near solid surfaces. The project undertakes detailed study of flame spread in ....Fundamental Fire Properties From Extinction and Piloted Ignition Experiments of Solid Fuels. Current approval methods for determining fire properties of construction materials are often incorrect in yielding properties that can be used in situations removed from test conditions. The main aim of this project is to obtain fundamental fire properties by examining the ignition and extinction processes of diffusion flames near solid surfaces. The project undertakes detailed study of flame spread in the direction opposite to the flow of air, which defines the initial fire growth and is important in fire propagation. Results from this project will provide scientific underpinning for the development of approval standards for new materials, which are needed to support Australia's transition from prescriptive to performance based building codes.Read moreRead less

The project falls within Research Priority 3: Frontier Technologies for Building and Transforming Australian Industries. This generic work involves cutting-edge multidisciplinary research leading to better understanding of the fundamental principles governing the behaviour of hybrid materials. The proposed framework of internally engineered architecture will enrich the existing set of available methods of designing new materials, extend the knowledge base of the discipline and maintain Australia's leading position in the field. Australian Industry will benefit directly from unique engineering properties and functionalities that hybrids provide. This contributes to Priority Goals: Breakthrough Science and Advanced Materials.Read moreRead less
Determining the Toxicity of Sedimentary Organic Contaminants in the Marine Environment and its implications for Australia. Australia, like many countries, has adopted sediment quality guidelines, which govern construction, waste disposal, dredging, protection of living resources and remediation in coastal regions. Recent studies by the current applicants indicate that these guidelines overestimate sediment toxicity, which may result in unnecessary, costly environmental investigations and possibl ....Determining the Toxicity of Sedimentary Organic Contaminants in the Marine Environment and its implications for Australia. Australia, like many countries, has adopted sediment quality guidelines, which govern construction, waste disposal, dredging, protection of living resources and remediation in coastal regions. Recent studies by the current applicants indicate that these guidelines overestimate sediment toxicity, which may result in unnecessary, costly environmental investigations and possibly needless, very expensive remediation. Although contaminants are in extremely high concentrations in many Australian coastal areas, they may not be available (bioavailable) to benthic animals. A new technique is proposed to determine contaminant bioavalibility and improve the predictability of these guidelines and ensure the ecological sustainable development of coastal environments.Read moreRead less
Effective and accurate model dynamics, deterministic and stochastic, across multiple space and time scales. A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are often known, but the closures to translate microscal ....Effective and accurate model dynamics, deterministic and stochastic, across multiple space and time scales. A persistent feature of complex systems in engineering and science is the emergence of macroscopic, coarse grained, coherent behaviour from the interactions of microscopic agents (molecules, cells, grains) and with their environment. In current modeling, ranging from ecology to materials science, the underlying microscopic mechanisms are often known, but the closures to translate microscale knowledge to a system level macroscopic description are rarely available in closed form. Our novel methodology will explore this stumbling block, and promises to radically change the modeling, exploration and understanding of multiscale complex system behaviour.Read moreRead less
Engineering functional nerves using microtailored culture systems. The aim of this work is to develop new culture systems for developing and growing nerves outside of the body. The project will generate knowledge and engineering technology for production of neural implants suitable for medical applications. The availability of engineered nerve grafts to repair neural injuries will improve patient health outcomes.
Heat transfer in novel solar thermal reactors to process minerals and solar fuels. The project will develop new design tools for optimising novel solar reactors for the production of solar fuels and for low emission minerals processing. It will enable substantial cost reductions in these technologies and establish a unique and leading program in solar power tower technology within Australia.
