Abstract

This paper investigates the autoxidation of alkanes, a crucial class of molecules in fuels and urban atmospheric environments. Utilizing advanced mass spectrometry, the researchers demonstrate that alkanes undergo autoxidation more efficiently than previously believed, under both atmospheric and combustion conditions. Even with high NOx concentrations, significant amounts of highly oxygenated products are formed, contributing to urban organic aerosol. This interdisciplinary study provides critical insights into oxidation processes relevant to engine efficiency and air quality.
