Urban air pollution represents one of the greatest environmental challenges facing mankind
in the 21st century. 1, 2 Noticeably, many developing countries, such as China and India …

Iodic acid (HIO3) is known to form aerosol particles in coastal marine regions, but predicted
nucleation and growth rates are lacking. Using the CERN CLOUD (Cosmics Leaving …

The main nucleating vapor in the atmosphere is thought to be sulfuric acid (H2SO4),
stabilized by ammonia (NH3). However, in marine and polar regions, NH3 is generally low …

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 …

Proton-transfer reaction mass spectrometry (PTR-MS) is a technique developed almost
exclusively for the detection of gaseous organic compounds in air. Volatile organic …

This review is concerned with the theoretical and computational modeling of bimolecular
reactions, especially with generally applicable methods for kinetics (ie, overall rates as …

Over the last decade, scientific and engineering interests have been shifting from
conventional ion mobility spectrometry (IMS) to field asymmetric waveform ion mobility …

We review the gas-phase chemistry in extraterrestrial space that is driven by reactions with
atomic and molecular ions. Ions are ubiquitous in space and are potentially responsible for …
