Microreactors for Organic Synthesis. Since the electronic revolution, miniaturisation has been the trend for devices from consumer electronics to scientific instruments. In this time very little has changed in the manner, or scale, that synthetic organic chemistry has been carried out even though advances in instrumentation mean that less compound is required for identification and analysis.

Since the electronic revolution, miniaturisation has been the trend for devices from consumer electronics to scientific instruments. In this time very little has changed in the manner, or scale, that synthetic organic chemistry has been carried out even though advances in instrumentation mean that less compound is required for identification and analysis. This project aims to bridge the gap by developing recyclable miniaturised reaction vessels for the formation of organic compounds on a scale thousands of times smaller than it is currently done. These devices will have applications in drug discovery programmes due to higher throughput and increased efficiency while minimising waste.Read moreRead less
Switchable and stereocontrolled photoredox catalysis. This project aims to develop new catalytic synthetic reactions for the rapid and more direct functionalisation of organic compounds under mild conditions with the use of visible light. An integrated experimental and computational approach will be used to design potent visible-light photocatalysts that retain the advantages of standard photoredox catalysis but with the added ability to intercept and, thus control, reactive intermediates in sit ....Switchable and stereocontrolled photoredox catalysis. This project aims to develop new catalytic synthetic reactions for the rapid and more direct functionalisation of organic compounds under mild conditions with the use of visible light. An integrated experimental and computational approach will be used to design potent visible-light photocatalysts that retain the advantages of standard photoredox catalysis but with the added ability to intercept and, thus control, reactive intermediates in situ. This will enable the control of stereochemistry in photoredox reactions – not possible with standard catalysts - and establish other useful synthetic transformations. These strategies will make it easier to prepare valuable classes of organic molecules – efficiently, safely, and cost-effectively.

Harnessing light and electricity to drive chemical synthesis. This project will explore and establish original strategies that use inputs of energy (light and electricity) to break or form chemical bonds, which can provide new or improved access to valuable compounds. In this way, this research will augment or enhance existing methods for the selective and direct manipulation of molecules by creating tools that allow chemists to prepare molecules under particularly mild conditions. The outcomes ....Harnessing light and electricity to drive chemical synthesis. This project will explore and establish original strategies that use inputs of energy (light and electricity) to break or form chemical bonds, which can provide new or improved access to valuable compounds. In this way, this research will augment or enhance existing methods for the selective and direct manipulation of molecules by creating tools that allow chemists to prepare molecules under particularly mild conditions. The outcomes of the project will include the development of new technology for organic synthesis and forging novel approaches for chemical alkylation and cross-coupling reactions. This can contribute to making important compounds more efficiently, safely and cheaper to produce in the future.Read moreRead less
Extraction of gold from thiosulfate leach liquors using selective magnetic ion exchange (MIEX) resins. Cyanide processes used for gold leaching can cause severe environmental problems. This proposal studies the use of thiosulfate as an alternative, concentrating on the design and synthesis of new functionalised magnetic ion-exchange resins, which will act as selective adsorbents for the gold thiosulfate complex and thereby facilitate the implementation of this efficient, low environmental impact ....Extraction of gold from thiosulfate leach liquors using selective magnetic ion exchange (MIEX) resins. Cyanide processes used for gold leaching can cause severe environmental problems. This proposal studies the use of thiosulfate as an alternative, concentrating on the design and synthesis of new functionalised magnetic ion-exchange resins, which will act as selective adsorbents for the gold thiosulfate complex and thereby facilitate the implementation of this efficient, low environmental impact process. Since the leaching is typically applied to ores rich in copper, resins for the recovery of copper will also be designed. Laboratory proving trials will be conducted and successful candidates will be considered for future commercialisation of a Resin-in-Pulp leaching and recovery process.Read moreRead less
