Aerosol particles in the atmosphere profoundly influence public health and climate. Ultrafine
particles enter the body through the lungs and can translocate to essentially all organs, and …

Molecular clusters are ubiquitous constituents of the ambient atmosphere, that can grow into
larger sizes forming new aerosol particles. The formation and growth of small clusters into …

New particle formation of liquid or solid nanoparticles from gas-phase precursors is a
decisive process in Earth's atmosphere and is considered one of the largest uncertainties in …

Gas-phase autoxidation—regenerative peroxy radical formation following intramolecular
hydrogen shifts—is known to be important in the combustion of organic materials. The …

Aerosol particles are important for our global climate, but the mechanisms and especially the
relative importance of various vapors for new particles formation (NPF) remain uncertain …

Iodic acid (IA) has recently been recognized as a key driver for new particle formation (NPF)
in marine atmospheres. However, the knowledge of which atmospheric vapors can enhance …

Over Boreal regions, monoterpenes emitted from the forest are the main precursors for
secondary organic aerosol (SOA) formation and the primary driver of the growth of new …

Atmospheric organic acids (OAs) are expected to enhance methanesulfonic acid (MSA)-
driven new particle formation (NPF). However, the exact role of OAs in MSA-driven NPF …

Aerosol nanoclusters (AN), defined here as molecular aggregates suspended in a gas with
dimensions between 2 and 10 nm, are the link between substances that we think of as …

Dimethyl sulfide (DMS) is the dominant biogenic sulfur compound in the ambient marine
atmosphere. Low-volatility acids from DMS oxidation promote the formation and growth of …
