Authors show the complexity of atmospheric chemistry

The study conducted by Rawan AbouHaidar, Denis Duflot and Celine Toubin delves into the complexity of atmospheric chemistry, particularly the heterogeneous reaction between maleic acid and ozone within aqueous phases. Their research investigates the molecular-level details of this reaction, employing a combination of classical and quantum methods to understand its mechanism and kinetics in both gas, surface and bulk phases.

The key findings underscore the significance of multiphase processes in atmospheric chemistry, revealing that the presence of interfacial water molecules enhances the reaction between ozone and maleic acid aerosol particles. The published article, titled "Theoretical characterization of the kinetics of the multiphase ozonolysis of an aqueous maleic acid droplet" in Aerosol Science and Technology (published on December 4, 2023), demonstrates the strength of their multilevel theoretical approach.
