Free Radical Multiphase Chemistry on Tropospheric Photoreactive Particles

Abstract Gas-phase and multiphase reactions of free radicals play pivotal roles in tropospheric chemistry. Recent studies indicate that photoinduced multiphase reactions serve as a potential source of free radicals rather than a traditional sink. To accurately evaluate their envi...

Spontaneous ChlorineGeneration via Interfacial Oxidationof Chloride by O2 on Acidic Microdroplets

Abstract Reactive chlorine species significantly influence atmospheric chemistry, yet their sources remain inadequately defined. We have discovered a spontaneous formation pathway for substantial molecular chlorine (Cl2) from the oxidation of chloride (Cl–) through interfacial ox...
