Reconceptualising the information system as a service. Through parallel efforts in Australia and China, the study aims to propel 'IS-Impact', the Australia-originated and most extensively validated IS success measurement model, to become the Information Systems evaluation approach of choice globally, in both research and practice.
Hybrid cathode for low temperature solid oxide fuel cells. This project aims to develop molten carbonate-perovskite hybrid cathode materials for low temperature solid oxide fuel cells (LT-SOFCs) possessing both high catalytic activity towards oxygen reduction reaction (ORR) and high tolerance to carbon dioxide poisoning. Carbon dioxide in air can poison nearly all the perovskite cathode materials developed for LT-SOFCs (below 600 degrees C) so far. These materials will not be practically useful ....Hybrid cathode for low temperature solid oxide fuel cells. This project aims to develop molten carbonate-perovskite hybrid cathode materials for low temperature solid oxide fuel cells (LT-SOFCs) possessing both high catalytic activity towards oxygen reduction reaction (ORR) and high tolerance to carbon dioxide poisoning. Carbon dioxide in air can poison nearly all the perovskite cathode materials developed for LT-SOFCs (below 600 degrees C) so far. These materials will not be practically useful until carbon dioxide poisoning can be prevented. This project expects to make these LT-SOFC cathode materials commercially viable, solving a problem for the widespread use of low temperature solid oxide fuel cells.Read moreRead less
A new methodology for the measurement of transition metals ions in complex, high temperature oxide systems relevant to non-ferrous metal production. Complex multi-component molten oxide phases, known commonly as slags, are used in the high temperature production and refining of metals. The slag systems of commercial interest contain transition metals species, such as, Fe2+, Fe3+. Each of these species behaves as if it were a separate chemical component. Researchers at the University of Queensla ....A new methodology for the measurement of transition metals ions in complex, high temperature oxide systems relevant to non-ferrous metal production. Complex multi-component molten oxide phases, known commonly as slags, are used in the high temperature production and refining of metals. The slag systems of commercial interest contain transition metals species, such as, Fe2+, Fe3+. Each of these species behaves as if it were a separate chemical component. Researchers at the University of Queensland have developed a new methodolgy, which enables the concentrations of these transition metal ions to be measured.
These types of measurements cannot be made with any of the techniques currently in use. The study will provide data on high temperature slags in a number of industrially and scientifically important systems. This approach will be applicable to a wide range of chemical systems in the fields of extractive metallurgy, materials science and geology; systems which could not previously be characterised.Read moreRead less
High Performance Anode for Direct Ammonia Solid Oxide Fuel Cells. Solid oxygen fuel cells are a clean energy generation device with very high energy efficiency and if with hydrogen as fuel, the emission is zero. However, the utilisation of hydrogen is limited by on-board storage. Ammonia is a promising hydrogen carrier and can be directly fed to solid oxide fuel cells without fuel storage problem, and the products are just hydrogen and nitrogen. For direct ammonia solid oxide fuel cells, the key ....High Performance Anode for Direct Ammonia Solid Oxide Fuel Cells. Solid oxygen fuel cells are a clean energy generation device with very high energy efficiency and if with hydrogen as fuel, the emission is zero. However, the utilisation of hydrogen is limited by on-board storage. Ammonia is a promising hydrogen carrier and can be directly fed to solid oxide fuel cells without fuel storage problem, and the products are just hydrogen and nitrogen. For direct ammonia solid oxide fuel cells, the key challenge is the anode. This project aims to develop a high performance anode for direct ammonia solid oxide fuel cells with both high activity and high stability at low temperature (below 600 degree C), thus addressing a key issue to make the direct ammonia solid oxide fuel cells commercially viable.Read moreRead less
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
A theory of communicative practices within financial internet discussion site communities. This project aims to use online financial investment communities to identify factors that drive communication and influence knowledge co-creation, examine how systematic variations in these factors influence investor decision making, and develop a mid-range theory for explaining and predicting the influence of online communication patterns on individual decisions and market outcomes. By developing and vali ....A theory of communicative practices within financial internet discussion site communities. This project aims to use online financial investment communities to identify factors that drive communication and influence knowledge co-creation, examine how systematic variations in these factors influence investor decision making, and develop a mid-range theory for explaining and predicting the influence of online communication patterns on individual decisions and market outcomes. By developing and validating a new mid-range theory, initially in the financial investment context, this project will provide significant benefits, such as help to secure Australia’s place in a changing world through improved information flow.Read moreRead less

The aim of the project is to generate theoretical knowledge on how to govern agile teams effectively. Effective governance of software development projects is essential for companies to protect their information technology investments. Nowadays, companies have migrated to agile software development where requirements and solutions evolve iteratively and change frequently; yet formal approaches to governance (eg steering committee and detailed plans) are ineffective and impede flexibility, agility and creativity. This project aims to identify informal governance approaches for agile projects based on team embeddedness and network theory. With this knowledge, management could ensure projects deliver value at an acceptable cost, quality and timescale.Read moreRead less
