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 …

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 …

Organosulfates (OSs), also referred to as organic sulfate esters, are well-known and
ubiquitous constituents of atmospheric aerosol particles. Commonly, they are assumed to …

Isoprene-derived secondary organic aerosol (SOA) is mainly formed through acid-catalyzed
reactive uptake of isoprene-derived epoxydiols (IEPOX) onto sulfate aerosol particles. The …

Atmospheric ice nucleating particles (INPs) influence global climate by altering cloud
formation, lifetime, and precipitation efficiency. The role of secondary organic aerosol (SOA) …

Secondary organic aerosols (SOA) are crucial constitution of fine particulate matter (PM),
which are mainly derived from photochemical oxidation products of primary organic matter …

Conspectus The pH of a solution is one of its most fundamental chemical properties,
impacting reaction pathways and kinetics across every area of chemistry. The atmosphere is …

Exposure to ozone and fine particle (PM2. 5) air pollution results in premature death. These
pollutants are predominantly secondary in nature and can form from nitrogen oxides (NO x) …

Exposure to fine particulate matter (PM2. 5) from fuel combustion significantly contributes to
global and US mortality. Traditional control strategies typically reduce emissions for specific …

To predict important secondary organic aerosol (SOA) properties, information on viscosity or
diffusion rates within SOA is needed. Ozonolysis of β-caryophyllene is an important SOA …
