The acidity of aqueous atmospheric solutions is a key parameter driving both the partitioning
of semi-volatile acidic and basic trace gases and their aqueous-phase chemistry. In addition …

Sulfate aerosol contributes to particulate matter pollution and plays a key role in aerosol
radiative forcing, impacting human health and climate change. Atmospheric models tend to …

SO2 removal is critical to flue gas purification. However, based on performance and cost,
materials under development are hardly adequate substitutes for active carbon-based …

The Arctic is warming at almost four times the global rate. An estimated sixty percent of
greenhouse‐gas‐induced Arctic warming has been offset by anthropogenic aerosols, but …

For a generation or more, the mass spectrometry that developed at the frontier of molecular
biology was worlds apart from isotope ratio mass spectrometry, a label-free approach done …

Sulfate aerosols affect climate by scattering radiation and by changing the microphysical
properties of water clouds. In much of the continental interiors that are overwhelmed by …

Arctic warming has accelerated surface melting even in the highland areas of the Greenland
ice sheet (GrIS). Understanding the relationship between climate and surface melting is …

Anthropogenic sulfate aerosols are estimated to have offset 60% of greenhouse-gas-
induced warming in the Arctic, a region warming four times faster than the rest of the world …

Chemical physics plays a large role in determining the isotopic compositions of gases in
Earth's atmosphere, which in turn provide fundamental insights into the sources, sinks, and …

Traditional atmospheric chemistry posits that sulfur dioxide (SO2) can be oxidized to sulfate
(SO42–) through aqueous-phase reactions in clouds and gas-phase oxidation. Despite …
