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 …

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 …

The first step in atmospheric new particle formation involves the aggregation of gas phase
molecules into small molecular clusters that can grow by colliding with gas molecules and …

In the present-day atmosphere, sulfuric acid is the most important vapour for aerosol particle
formation and initial growth. However, the growth rates of nanoparticles (< 10 nm) from …

We have collected, recomputed, and compiled a database consisting of 633 unique
atmospherically relevant molecular clusters containing sulfuric acid, bases, oxidized organic …

We explored the hypothesis that on the nanoscale level, acids and bases might exhibit
different behavior than in bulk solution. Our study system consisted of sulfuric acid, formic …

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 …

Sulfuric acid can act as a catalyst of its own formation. We have carried out a computational
investigation on the gas-phase formation of H2SO4 by hydrolysis of SO3 involving one and …

Quantum chemical studies of the formation and growth of atmospheric molecular clusters
are important for understanding aerosol particle formation. However, the search for the …
