Linking soil acidification with carbon dynamics in Australian agroecosystems. The ability to mitigate climate change by sequestering soil carbon may be limited in acidic soils, which are prevalent in Australia. The project will investigate the link between carbon cycling, soil acidification and liming, and provide important knowledge to identify agricultural practices which have the capacity to build soil carbon.

Summary
Nanowire photoelectrodes for carbon dioxide conversion. Returning carbon dioxide (CO2) to a useful state is a significant and challenging problem which requires appropriate devices and energy input. By utilising sunlight as a promising and green energy input, the conversion of CO2 into liquid fuel would positively impact the global carbon balance. This project aims to prepare abundant, non-toxic and sufficiently active photoelectrodes with one dimensional nanostructure, then develop appropriate ....Nanowire photoelectrodes for carbon dioxide conversion.

By utilising sunlight as a promising and green energy input, the conversion of CO2 into liquid fuel would positively impact the global carbon balance. This project aims to prepare abundant, non-toxic and sufficiently active photoelectrodes with one dimensional nanostructure, then develop appropriate and robust photoelectrochemical devices to convert CO2 into liquid fuels. This project aims to help reduce the atmospheric CO2 concentrations and explore a new energy source.Read moreRead less

Resources, industry and rural communities, the backbone of Australian economy, are confronted by unprecedented challenges of carbon pollution reduction, land conservation and eco-sustainability to combat global climate change. This exciting, highly integrated and multidisciplinary project will develop a scientific basis and technological options for the resources industry and remote communities to respond to these challenges. The outcomes of this research will enable the deployment of renewable biomass energy technology, bio-char for carbon storage, and affect the restoration of marginal lands and salinity levels in an environmentally and economically sustainable way, thus contributing to the development of an environmentally sustainable Australia.Read moreRead less

Integrated 2MHz Nuclear Magnetic Resonance high temperature tri-axial flow cell apparatus. The development of an integrated facility for petrophysical measurements allows the efficient use of expensive rock cores from gas or liquid reservoirs to develop reliable cross-correlations at conditions encountered in real reservoirs. The equipment is optimised for applications to unconventional reservoirs like Australia’s gas resources, in particular coal-bed methane reservoirs and gas reservoirs where ....Integrated 2MHz Nuclear Magnetic Resonance high temperature tri-axial flow cell apparatus.

Anticipating closure of bauxite refineries in Western Australia: the water quality implications of a proposed new design in residue storage areas. Refining bauxite is a major industrial activity in Australia, with economic benefits and a high potential for environmental impact. Many bauxite refineries are sited in rural areas. Community interests are given high priority in developing strategies for long-term storage of residue. These community interests include minimal impact on farmland, water, ....Anticipating closure of bauxite refineries in Western Australia: the water quality implications of a proposed new design in residue storage areas. Refining bauxite is a major industrial activity in Australia, with economic benefits and a high potential for environmental impact. Many bauxite refineries are sited in rural areas. Community interests are given high priority in developing strategies for long-term storage of residue. These community interests include minimal impact on farmland, water, health and natural ecosystems. Some of the refinery residue can be re-used in applications such as road construction, thus reducing the need to find other materials for this purpose. This project will investigate new residue management practices which could lead to better ways of establishing a sustainable vegetation cover and avoiding the impact of drainage water on the environment.Read moreRead less
Carbon conundrum: Functional characterisation of organic matter-clay mineral interactions in relation to carbon sequestration. Carbon sequestration in soil has been recognised as one of the possible measures through which greenhouse gas emissions can be mitigated.

Carbon sequestration in soil has been recognised as one of the possible measures through which greenhouse gas emissions can be mitigated. The major processes involved in carbon sequestration in soil include chemical immobilisation of carbon with soil particles and physical protection in the pores of soil microaggregates. These two processes are mediated through the functional relationships of soil organic matter and clay mineral interactions in soils. This project investigates nanoscale organomineral association underlying microaggregate formation and stability, as well as the distribution and microbial decomposition of carbon within microaggregates using a suite of advanced spectroscopic, molecular and isotopic techniques.Read moreRead less
Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An ....Fires, black carbon, greenhouse gas emissions and the carbon balance of southern sclerophyll forests. Ecologically sustainable forest management requires an understanding of the role of fire in the carbon balance of native forests, and in Australia's overall carbon balance. Fires are crucial to both this carbon balance and to the ecology of the forests. This project will help forest managers make decisions about using prescribed fire to manage fuels while at the same time managing carbon. An aim of management is to identify fire regimes that will optimise the carbon outcome as well as provide protection to life and property. This project will help managers meet that aim by developing a quantitative understanding of how much stable, black carbon (charcoal) is produced and how it affects other soil processes.Read moreRead less
Methane uptake of forest soils. This project will provide a detailed understanding of capacity of soils in Australia to sequester the greenhouse gas methane. It will identify the main factors and processes controlling methane uptake in soils and improve predictive models will allow us to predict methane uptake in the future.

This project aims to determine how manipulation of wetland hydrology can alter sulphur and iron cycling to inhibit methane emission and improve wetland net-carbon sequestration. Wetlands are among earth's most efficient ecosystems for carbon sequestration, but methane emission can offset this capacity.

This project aims to determine how manipulation of wetland hydrology can alter sulphur and iron cycling to inhibit methane emission and improve wetland net-carbon sequestration. Wetlands are among earth's most efficient ecosystems for carbon sequestration, but methane emission can offset this capacity. Redox cycling of sulphur and iron in wetlands can inhibit methane emission, but the precise biogeochemical processes and their efficiency are very poorly constrained due to a lack of studies—especially in Australian freshwater wetlands. This project is expected to inhibit methane emission in freshwater wetlands and maximise their net carbon sequestration efficiency.Read moreRead less
