Atmospheric aerosols are complex mixtures of different chemical species, and individual
particles exist in many different shapes and morphologies. Together, these characteristics …

Detection of bioaerosols, or primary biological aerosol particles (PBAPs), has become
increasingly important for a wide variety of research communities and scientific questions. In …

Acid-catalyzed reactions between gas-and particle-phase constituents are critical to
atmospheric secondary organic aerosol (SOA) formation. The aerosol-phase state is thought …

Measuring the acidity of atmospheric aerosols is critical, as many key multiphase chemical
reactions involving aerosols are highly pH-dependent. These reactions impact processes …

Single-particle mass spectrometry (SPMS) instruments characterize the composition of
individual aerosol particles in real time. Their fundamental ability to differentiate the …

The Arctic is experiencing the greatest warming on Earth, as most evident by rapid sea ice
loss. Delayed sea ice freeze-up in the Alaskan Arctic is decreasing wintertime sea ice extent …

Atmospheric aerosol acidity impacts key multiphase processes, such as acid-catalyzed
reactions leading to secondary organic aerosol formation, which impact climate and human …

Physicochemical analysis of individual atmospheric aerosols at the most abundant sizes in
the atmosphere (< 1 μm) is analytically challenging, as hundreds to thousands of species …

Aerosol acidity increases secondary organic aerosol (SOA) formed from the reactive uptake
of isoprene-derived epoxydiols (IEPOX) by enhancing condensed-phase reactions within …

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 …
