New particle formation has been estimated to produce around half of cloud‐forming particles
in the present‐day atmosphere, via gas‐to‐particle conversion. Here we assess the …

Fundamental questions remain about the origin of newly formed atmospheric aerosol
particles because data from laboratory measurements have been insufficient to build global …

Theoretical and experimental analyses of the steady state, bipolar diffusion charge
distribution on nanoparticles are reviewed. This charge distribution plays a critical role in …

Molecular clustering is the initial step of atmospheric new particle formation (NPF) that
generates numerous secondary particles. Using two online mass spectrometers with and …

We report comprehensive, demonstrably contaminant‐free measurements of binary particle
formation rates by sulfuric acid and water for neutral and ion‐induced pathways conducted …

Atmospheric new particle formation (NPF), which is observed in many environments
globally, is an important source of boundary-layer aerosol particles and cloud condensation …

Binary nucleation of sulfuric acid and water as well as ternary nucleation involving ammonia
are thought to be the dominant processes responsible for new particle formation (NPF) in the …

The formation of secondary particles in the atmosphere accounts for more than half of global
cloud condensation nuclei. Experiments at the CERN CLOUD (Cosmics Leaving OUtdoor …

It was recently shown by the CERN CLOUD experiment that biogenic highly oxygenated
molecules (HOMs) form particles under atmospheric conditions in the absence of sulfuric …

This open access title presents atmospheric simulation chambers as effective tools for
atmospheric chemistry research. State-of-the-art simulation chambers provide …
