Lecturer of Physical Chemistry
John Wenger graduated from the University of East Anglia with a BSc and PhD in chemical sciences. After spending one year as research associate at the University of Nottingham he was appointed as a postdoctoral fellow at University College Dublin. Here he developed his interests in atmospheric chemistry, specialising in the gas phase reactions that contribute to air pollution. John Wenger was appointed as College Lecturer at UCC in 1999.
Current research activities concern the gas phase reactions of oxygenated and halogenated organic compounds that are released into the atmosphere. This involves:
· Kinetic and product studies in small reactor systems
· Development of atmospheric degradation mechanisms in collaboration with other European research groups
· Validation of chemical mechanisms under realistic atmospheric conditions at the outdoor European Photoreactor in Valencia, Spain.
The information gained from these studies can then be used to ascertain the environmental acceptability of alternative solvents and fuel additives.
