Acidity, defined as pH, is a central component of aqueous chemistry. In the atmosphere, the
acidity of condensed phases (aerosol particles, cloud water, and fog droplets) governs the …

Highly oxygenated organic molecules (HOM) are formed in the atmosphere via autoxidation
involving peroxy radicals arising from volatile organic compounds (VOC). HOM condense on …

Advanced oxidation processes (AOPs) are increasingly applied in water and wastewater
treatment. Understanding the role of reactive species using probes and quenchers is one of …

This Review aims to critically analyse the emerging field of chemical reactivity at aqueous
interfaces. The subject has evolved rapidly since the discovery of the so-called 'on-water …

Anthropogenic emissions and land use changes have modified atmospheric aerosol
concentrations and size distributions over time. Understanding preindustrial conditions and …

Hydroxyl radical (OH) is a key oxidant that triggers atmospheric oxidation chemistry in both
gas and aqueous phases. The current understanding of its aqueous sources is mainly …

The hydroxyl radical (• OH) is one of the most powerful oxidizing agents, able to react
unselectively and instantaneously with the surrounding chemicals, including organic …

Atmospheric oxidation of sulfur dioxide (SO2) forms sulfate-containing aerosol particles that
impact air quality, climate, and human and ecosystem health. It is well-known that in-cloud …

Fine-particle pollution associated with winter haze threatens the health of more than 400
million people in the North China Plain. Sulfate is a major component of fine haze particles …

Predicting the formation of ice in the atmosphere presents one of the great challenges in
physical sciences with important implications for the chemistry and composition of the …
