Composites for thermal expansion matched oxygen electrodes. This project aims to develop high performance composite oxygen electrodes by using both negative thermal expansion materials and electrolyte materials to tailor the thermal expansion and activities of the perovskite-based electrodes for use in reduced temperature solid oxide cells. Such composite electrodes will show highly matched thermal expansion with electrolyte without sacrificing high activity at reduced temperatures. This project ....Composites for thermal expansion matched oxygen electrodes. This project aims to develop high performance composite oxygen electrodes by using both negative thermal expansion materials and electrolyte materials to tailor the thermal expansion and activities of the perovskite-based electrodes for use in reduced temperature solid oxide cells. Such composite electrodes will show highly matched thermal expansion with electrolyte without sacrificing high activity at reduced temperatures. This project seeks to address an important practical issue in the operation of solid oxide power cells - thermal expansion compatibility, which causes poor efficiency outside a narrow temperature band.Read moreRead less
Redox processes in Bayer liquors. Alumina, and the aluminium produced from it, are amongst Australia's most important mineral commodities, earning about $8 billion p.a. in exports. However, ongoing technological improvements are needed for Australian producers to remain globally competitive. This project addresses a key problem in alumina production - the behaviour of organic impurities - which will help to increase industrial productivity and reduce energy consumption. Insights gained from this ....Redox processes in Bayer liquors. Alumina, and the aluminium produced from it, are amongst Australia's most important mineral commodities, earning about $8 billion p.a. in exports. However, ongoing technological improvements are needed for Australian producers to remain globally competitive. This project addresses a key problem in alumina production - the behaviour of organic impurities - which will help to increase industrial productivity and reduce energy consumption. Insights gained from this research will also minimize the environmental and occupational health impacts of various process emissions, making the industry more sustainable.Read moreRead less
Improving the Performance of Lead Anodes in the Electrowinning of Copper. The aim of this project is the development of a fundamental understanding of the role of certain metal ions such as cobalt and manganese in modifying the electrochemical and corrosion performance of lead alloy materials used as anodes in the electrowinning of base metals such as copper, zinc and nickel.
The development of improved anodes will be of major benefit to the industry in terms of anode cost and particularly ener ....Improving the Performance of Lead Anodes in the Electrowinning of Copper.

The development of improved anodes will be of major benefit to the industry in terms of anode cost and particularly energy consumption. This project will lead to a better understanding of the performance of these anodes and could result in the design of improved anode materials and/or operating strategies.Read moreRead less
