Robust fluid mixing through topological chaos. The Australian chemicals and plastics industry has an annual turnover of over $20 billion and employs over 77,000 people; fluid mixing is fundamental to this industry, yet the industry is recognised as underinvesting in research and development in this essential area. Furthermore, frontier technologies such as biotechnology and the next generation of smart materials also crucially rely on fluid mixing. This project aims to evaluate a new paradigm ( ....Robust fluid mixing through topological chaos. The Australian chemicals and plastics industry has an annual turnover of over $20 billion and employs over 77,000 people; fluid mixing is fundamental to this industry, yet the industry is recognised as underinvesting in research and development in this essential area. Furthermore, frontier technologies such as biotechnology and the next generation of smart materials also crucially rely on fluid mixing. This project aims to evaluate a new paradigm (topological chaos) for the design of mixers, to provide better and more robust mixers that work from microscopic to industrial scales.Read moreRead less

Photonic crystal enhanced quantum dot infrared photodetectors are a new generation of detectors developed from integrating nanotechnology with material science and optics. This would not only enhance the detector performance but the structure will now detect a narrow band around the desired wavelength with multi-colour detectivity. The technology developed in this project is anticipated to attract interest from the industries and government agencies. It will be pervasive for use at home, in the manufacturing and mining industry, environmental and pollution monitoring, defence and national security.

Drag Force on Bubbles and Particles in Turbulent Flows. Australian exports are dominated by the minerals, metallurgical and chemicals industries, with minerals exports worth at least $40 billion annually. Many of the production processes are underpinned by the complex interaction between particles, bubbles and liquids. It is important that we understand the complex interactions taking place. This will enable us to improve existing operations and also to design completely new technologies, especi ....Drag Force on Bubbles and Particles in Turbulent Flows. Australian exports are dominated by the minerals, metallurgical and chemicals industries, with minerals exports worth at least $40 billion annually. Many of the production processes are underpinned by the complex interaction between particles, bubbles and liquids. It is important that we understand the complex interactions taking place. This will enable us to improve existing operations and also to design completely new technologies, especially in the emerging fields of nano and biotechnology. This project is important because it adds to our knowledge in the national priority area of Transforming Australian Industries, and its success will ensure that our industries remain at the forefront of innovation and are globally competitive.

This proposal is consistent with National Research Priority 3: Frontier Technologies for Building and Transforming Australian Industries and the Priority Goals: Breakthrough Science, Advanced Materials and Frontier Technologies. Our ability to tailor the shape, size and orientation of metal nanocrystals will broaden the domestic knowledge base, enhance the national research profile and train young scientists, particularly in the use of two national facilities: the Australian Synchrotron and the ANU Heavy-Ion Accelerator Facility. Furthermore, domestic capabilities in materials characterisation and nanotechnology will be bolstered, state-of-the-art domestic industry will be enhanced and new technological applications will be enabled.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.

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
Silk Fibroin Optofluidic Chips. Unlike any other material, even any other biologically occurring material, silk is unique in being very transparent, able to be shaped on a very small scale and can keep natural chemicals like proteins and enzymes active. This project will use silk to make optical devices and sensors. Optics made from silk will have all these properties, which means that they can be used as sensors and devices in biochemistry applications that have never been possible before.

Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools ....Modelling and Measurement of Flow-Structure Dynamics in the Human Upper Airway. Sleep disruption due to the common and disabling conditions of snoring and obstruction of the human upper airway can result in chronic fatigue, lost work and accidents caused by daytime drowsiness. To date the behaviour of the upper airway has not been adequately studied in terms able to reveal the mechanical causes of these conditions. This deficiency is addressed through the development and use of simulation tools and measurement techniques that will elucidate the flow-structure dynamics leading to new diagnostic and improved treatment methods. Simulating the effect of treatment on any individual will permit it to be chosen to maximise its efficacy for a problem that costs the nation an estimated $2 Billion per year in lost productivity.Read moreRead less

will be based systematically upon established turbulence models to

new and robust computer models for thin layers of coating fluid will
aid many industrial processes. We also aim to provide correct initial
conditions and boundary conditions for simpler cases of the above
flows. The approach leads to a greater understanding of the range of
applicability of the models through better estimating the errors in the
modelling process. The project develops a fundamental enabling
methodology for engineering and the sciences.
