A comprehensive investigation by KAUST researchers sets the record straight on the formation of hydrogen peroxide in micrometre-sized water droplets, or microdroplets, and shows that ozone is the key to this transformation1, 2.
The air-water interface is a crucial site for numerous natural, domestic and industrial processes such as ocean-atmosphere exchange, cloud and dew formation, aerated beverages and bioreactors. Yet, probing chemical transformations at the air-water interface is challenging due to the lack of surface-specific techniques or computational models.
