Multiphase chemistry plays a vital role in the Earth system, climate, and health. Chemical
reactions, mass transport, and phase transitions between gases, liquids, and solids are …

Nitrous acid (HONO) plays a key role in tropospheric photochemistry, primarily due to its role
as a source of hydroxyl (OH) radicals via its rapid photolysis. OH radicals are involved in …

Many terrestrial surfaces, including soils, rocks and plants, are covered by photoautotrophic
communities, capable of synthesizing their own food from inorganic substances using …

Abstract The United States is now experiencing the most rapid expansion in oil and gas
production in four decades, owing in large part to implementation of new extraction …

Nitrous acid (HONO) is a major precursor of tropospheric hydroxyl radical (OH) that
accelerates the formation of secondary pollutants. The HONO sources, however, are not well …

External cycling regenerating nitrogen oxides (NOx≡ NO+ NO2) from their oxidative
reservoir, NOz, is proposed to reshape the temporal–spatial distribution of NOx and …

Photolysis of nitric acid on the surface has been found recently to be greatly enhanced from
that in the gas phase. Yet, photolysis of particulate nitrate (pNO3) associated with …

Nitrogen oxides are essential for the formation of secondary atmospheric aerosols and of
atmospheric oxidants such as ozone and the hydroxyl radical, which controls the self …

Nitrous acid (HONO) is a precursor of the hydroxyl radical in the atmosphere, which controls
the degradation of greenhouse gases, contributes to photochemical smog and ozone …

Acidity (pH) plays a key role in the physical and chemical behavior of PM2. 5. However,
understanding of how specific PM sources impact aerosol pH is rarely considered …
