Application of flow-round penetrometers for characterising soft sediments. Soft sediments present unique challenges in geotechnical engineering due to their sensitivity to disturbance during sampling. Strength measurement therefore relies on field tests, and novel penetrometers that force soil to flow around the probe have the potential for significantly improved accuracy compared with conventional cone penetrometers.

Soft sediments present unique challenges in geotechnical engineering due to their sensitivity to disturbance during sampling. Strength measurement therefore relies on field tests, and novel penetrometers that force soil to flow around the probe have the potential for significantly improved accuracy compared with conventional cone penetrometers. The project aims to establish a definitive framework for interpreting results of field tests using flow-round penetrometers, through careful comparison of laboratory and field strength measurements. Applications of the work range from characterising deepwater sediments for offshore developments, to monitoring the strength of pastes in the mining and materials handling industries.Read moreRead less

Gondwana in East Asia? A biogeographic test using Permian marine invertebrate biota. Combining Permian fossil collections from key Australian, NE Chinese, East Russian and Japanese localities, coupled with a detailed quantitative biogeographical analysis, this project will provide fundamental data for evaluating current plate tectonic models regarding the palaeo-positions of some of the tectonic blocks in East Asia.

Combining Permian fossil collections from key Australian, NE Chinese, East Russian and Japanese localities, coupled with a detailed quantitative biogeographical analysis, this project will provide fundamental data for evaluating current plate tectonic models regarding the palaeo-positions of some of the tectonic blocks in East Asia. In particular, this project will test, using biogeographical data, the validity of several recently proposed claims that continental East Asia contains some tectonic blocks of Gondwana origin. An improved understanding of the Permian palaeogeographical relationship between Gondwanaland and East Asia is critical for improving geological models for resources exploration and the understanding of earth history.Read moreRead less

A major problem in fluid pipelines and pipe networks is undetected leakage. This research collaboration will develop new approaches that will enable systematic leak detection using advanced numerical modelling and inverse techniques with the ultimate goal of implementing these leak detection methods in practice. In addition to the numerical model development, an extensive series of laboratory experiments will be undertaken by researchers from both universities using the laboratory facilities in Adelaide to verify and extend the new approaches.

Development of cyclic loading models for application in offshore geotechnics. The response of foundations for offshore structures to repetitive (cyclic) loads is a critical but still inadequately understood area of offshore geotechnics, with designs still usually based on simple modifications to monotonic loading conditions.

The response of foundations for offshore structures to repetitive (cyclic) loads is a critical but still inadequately understood area of offshore geotechnics, with designs still usually based on simple modifications to monotonic loading conditions. In this project, a definitive framework for modelling cyclic behaviour will be established. Using this new approach, numerical models will be developed to address problems at all scales from fundamental constitutive behaviour of soils to macroscopic models for large foundation systems. Their application to offshore design problems (for renewable energy as well as traditional oil and gas applications) will be assessed. Recommendations to current international guidelines will also be made.Read moreRead less
Composite cathode Materials for Lithium Ion Battery Using Chemical Coating Technique. Commercial Li-ion batteries have LiCoO2 as a cathode material due to its excellent cycle stability and rate capability. However, cobalt is a relatively rare and very expensive transition metal, so attention has been focussed on LiMn2O4 with a view to taking advantage of its low cost and environmentally friendly nature compared to LiCoO2. The aim of this develop new composite cathode materials by using a LCo02. ....Composite cathode Materials for Lithium Ion Battery Using Chemical Coating Technique.

The depletion of oil reserves and the effects of global warming make the development of new, clean, sustainable fuel production systems critically important. This frontier technology has the ability to drive solar-powered hydrogen production from water. Extending the system to marine algal cells provides the possibility of coupling clean fuel production with water purification as the product of H2 combustion is pure water. We have already engineered green algae that produce H2 from H2O at a rate ~1000% higher than the Wild-type and through this project will incorporate further improvements with the aim of developing a competitive H2 production system.Read moreRead less

University of Queensland/Arizona State University partnership to design industrially suitable zeolite membranes for desalination. For desalination, the highest costs are organic-based membrane replacement (lasting ~1 year) and energy requirement. Functionalised zeolitic membranes are low-cost, high performing, chemically tolerant and thermally stable.

For desalination, the highest costs are organic-based membrane replacement (lasting ~1 year) and energy requirement. Functionalised zeolitic membranes are low-cost, high performing, chemically tolerant and thermally stable. New zeolite membranes in principle could perform the separation outlasting their organic counterparts, while at the same time offering major energy reductions from higher fluxes. Current zeolite membrane research for desalination however is lacking. The proposed team offers experience in bringing highly significant lab scale technologies to industrial scales. The outcomes will address mutual priorities between Australia and USA for reliable low cost supply of fresh water.Read moreRead less

A mutlidisciplinery approach using molecular organic geochemical analyses combined with geological information will innovatively contribute to a coherent portrayal of the decline, collapse and subsequent recovery of biological species at the Permian/Triassic extinction event in Western Australia and other parts of the world. The proposed study will particulary focus on environmental changes closely related to deposition of petroleum source rocks globally but also focussing on the Perth Basin of the Triassic. This information will then be used to better identify rocks in Australia offering good sources of petroleum.Read moreRead less
