Surfactants are surface-active molecules or ions that can often be found at the surface of
atmospheric aerosol particles. Some surfactants, such as biomolecules in marine aerosol …

Perchlorotrityl radical (PTM), tris (2, 4, 6-trichlorophenyl) methyl radical (TTM),(3, 5-dichloro-
4-pyridyl) bis (2, 4, 6 trichlorophenyl) methyl radical (PyBTM),(N-carbazolyl) bis (2, 4, 6 …

The surface composition of aerosol droplets is central to predicting cloud droplet number
concentrations, understanding atmospheric pollutant transformation, and interpreting …

The hydroxyl radical,• OH, is one of the most reactive free radicals and plays significant roles
in the oxidative degradation of organic pollutants and the electron transfer of inorganic ions …

The surface of atmospheric aqueous aerosol is covered with an organic film. However, there
have been limited studies about the photochemical process between the organic coating …

The mechanism and kinetics of reactive oxygen species (ROS) formation when atmospheric
secondary organic aerosol (SOA) is exposed to solar radiation are poorly understood. In this …

The presence of an organic film on a cloud droplet or aqueous aerosol particle has the
potential to alter the chemical, optical and physical properties of the droplet or particle. In the …

A mechanistic study is reported for the reactions of singlet oxygen (1O2) with alkene
surfactants of tunable properties. Singlet oxygen was generated either top-down …

Abstract Humic-like substances (HULIS), a class of macromolecular photosensitizers, are
major components of light-absorbing aerosols in the atmosphere. Due to the amphiphilic …

The reaction of gas-phase SO2 with unsaturated carbon-carbon double bonds forms
organosulfates. Previous works have focused on reaction products and not the fate of …
