Blended calcium-magnesium binders for improved and more sustainable building materials. The project will explore the potential of new blended calcium-magnesium cements to significantly improve the sustainability and properties of concrete produced with Portland cement (PC). Concrete based on PC contributes to around 10% of global anthropogenic carbon dioxide. PC Concrete has many weaknesses such as rapid deterioration when exposed to aggressive environments, delayed reactions and early age crack ....Blended calcium-magnesium binders for improved and more sustainable building materials. The project will explore the potential of new blended calcium-magnesium cements to significantly improve the sustainability and properties of concrete produced with Portland cement (PC). Concrete based on PC contributes to around 10% of global anthropogenic carbon dioxide. PC Concrete has many weaknesses such as rapid deterioration when exposed to aggressive environments, delayed reactions and early age cracking caused by shrinkage. The proposed research will investigate ways of using the new binder system to overcome these weaknesses and to reduce carbon dioxide emission. The expected outcome will be a proven technology for manufacturing new building materials that are environmentally more sustainable and with enhanced properties.Read moreRead less
A new biophysical approach to understanding self-assembly of dairy proteins in real time in complex systems of industrial importance. The study seeks to understand the molecular basis of self-assembly (aggregation and gelation) of dairy proteins during thermal processing of dairy products. This will involve direct determination, in real time, of the extent, rate and degree of reversibility of the changes that take place. These include changes in the composition, structure and stability of the ca ....A new biophysical approach to understanding self-assembly of dairy proteins in real time in complex systems of industrial importance. The study seeks to understand the molecular basis of self-assembly (aggregation and gelation) of dairy proteins during thermal processing of dairy products. This will involve direct determination, in real time, of the extent, rate and degree of reversibility of the changes that take place. These include changes in the composition, structure and stability of the casein micelles, changes in properties such as pH and pCa and changes such as the denaturation of b-lactoglobulin and its binding to k -casein. The purpose of the study is to provide the scientific base for improving the consistency of manufactured dairy products and for developing new food ingredients with new functionalities thus opening up new opportunities for the dairy industry.Read moreRead less
Enhanced metal recovery from a modified Caron leach of mixed nickel-cobalt intermediate concentrate. Nickel metal production from lateritic deposits involves dissolution in acid followed by purification and selective alkaline precipitation of the nickel and cobalt as hydroxide phase. Hydroxides from several plants are transported to a central refinery where the hydroxide is redissolved in ammoniacal solutions and nickel and cobalt are separated and reduced to metal.

Hydroxides from several plants are transported to a central refinery where the hydroxide is redissolved in ammoniacal solutions and nickel and cobalt are separated and reduced to metal.
This project will examine the effect of preparation conditions and aging of the hydroxide precipitate on the refining process.
