Information Quality in Auctions of Multiple Objects. This project aims at using both theory and laboratory experiments to analyse the formation of prices and the buyers' behaviour at auctions of multiple objects. The study focusses on the comparison of simultaneous auction procedures (in which the objects are sold at once) to sequential auction procedures (in which the objects are sold one after the other) and attention is drawn on the effects of the quality of the buyers' information about the ....Information Quality in Auctions of Multiple Objects. This project aims at using both theory and laboratory experiments to analyse the formation of prices and the buyers' behaviour at auctions of multiple objects. The study focusses on the comparison of simultaneous auction procedures (in which the objects are sold at once) to sequential auction procedures (in which the objects are sold one after the other) and attention is drawn on the effects of the quality of the buyers' information about the assets to be sold on their bidding behaviour and on the seller's revenues. The conduct of laboratory experiments will provide a useful assessment of the theoretical predictions and valuable insights into the effects of buyers' information quality on their bidding behaviour at such markets.Read moreRead less

Water markets play a critical role in helping Australia’s food bowl survive periods of severe drought. This project aims to evaluate how the Murray-Darling Basin water markets performed, in terms of the impact of water ownership, and investigate how water reforms have affected rural communities over the past two decades. Expected outcomes include a clearer understanding on how different water ownership structures impact price and price volatility of water, market power, economic welfare of water traders, and what social and economic impacts water reforms in the past decades have in the Basin. The findings will provide critical evidence for evaluating future water reforms, building resilient rural communities and safeguarding food security.Read moreRead less

Recently developed, poly(urea-co-urethane) concrete floor screeds are used, in the construction industry, to provide protection against corrosive chemicals and abrasive wear; properties unmatched by other commercial floor treatments. Significantly such material has reduced environmental emissions and toxicity hazards. Factors, which affect the cure and performance of poly(urea-co-urethane) flooring materials will now be studied, including the uncontrolled release of carbon dioxide, which results in sporadic blister formation, leading to the on-site product failures that have severely limited the product's commercial growth. Clear understanding of cure chemistry and adhesion will be established for the first, allowing for the products further development.Read moreRead less

Solar-Driven C-H Functionalization Reactions. This project aims to investigate the functionalization reaction of unreactive C-H bonds using light as the source of energy. Light is a transformative change to synthesis as thermal activation is exchanged to solar activation. The latter gives access to excited state chemistry and enables reaction steps that are thermally inaccessible. It is a key strategy to leverage synthesis to the demands of the 21st century and to minimise its ecologic footprint ....Solar-Driven C-H Functionalization Reactions. This project aims to investigate the functionalization reaction of unreactive C-H bonds using light as the source of energy. Light is a transformative change to synthesis as thermal activation is exchanged to solar activation. The latter gives access to excited state chemistry and enables reaction steps that are thermally inaccessible. It is a key strategy to leverage synthesis to the demands of the 21st century and to minimise its ecologic footprint. At the same time this strategy provides a lever to profoundly impact and drive new concepts in synthesis. Significant benefits are expected, such as increase in fundamental knowledge on photochemical processes, but also the access to new materials for applications as drugs or OLEDs.Read moreRead less

Chalcopyrite, a major source of Cu, is often associated in ores with the valueless mineral pyrite. The development of more efficient methods for the retrieval of the Cu is of considerable economic importance to Australian minerals processing companies. We aim to develop methodologies allowing the more efficient :
- separation of chalcopyrite and pyrite;
- leaching of Cu from ores and tailing in a heap leach environment and
- leaching of Cu in a concentrated chalcopyrite-pyrite reactor environment.
These aims will be achieved via an integrated surface-solution speciation approach allowing the manipulation of surface properties.
