Estimation of mechanistic parameters in the gas-phase reactions of ozone with alkenes for use in automated mechanism construction Open
Reaction with ozone is an important atmospheric removal process for alkenes. The ozonolysis reaction produces carbonyls and carbonyl oxides (Criegee intermediates, CI), which can rapidly decompose to yield a range of closed shell and radic…

Opinion: The germicidal effect of ambient air (open-air factor) revisited Open
The term open-air factor (OAF) was coined following microbiological research in the 1960s and 1970s which established that rural air had powerful germicidal properties and attributed this to Criegee intermediates formed in the reaction of …
