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.

Laser Diagnostics of Soot Formation in Precessing Jet Flames. In many practical combustion systems (e.g., boiler furnaces and rotary kilns), flame radiation is the major contributor to the required heat transfer. Soot formation is a means of enhancing flame radiation provided the soot is completely oxidised within the flame so that there are no soot emissions. The enhanced flame radiation can have a significant economic and environmental impact on plant operation (changes to the parameters tha ....Laser Diagnostics of Soot Formation in Precessing Jet Flames. In many practical combustion systems (e.g., boiler furnaces and rotary kilns), flame radiation is the major contributor to the required heat transfer. Soot formation is a means of enhancing flame radiation provided the soot is completely oxidised within the flame so that there are no soot emissions. The enhanced flame radiation can have a significant economic and environmental impact on plant operation (changes to the parameters that influence soot formation can also influence NOx and greenhouse gas emissions). The objectives of this project are to identify and quantify the operating parameters that influence soot formation and destruction in such flames.Read moreRead less

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
