TL;DR: In this article, the authors discuss food-related applications of proton transfer reaction mass spectrometry (PTR-MS), an emerging technique that allows direct, fast, sensitive monitoring of VOCs.

TL;DR: A review of van der Waals clusters can be found in this paper, where the potential role of clusters in many applied fields, various classification schemes, and the unique position of clusters between the gaseous and solid state of matter are summarized.

TL;DR: In this article, the stability of singly charged C60+ fullerene ions, produced by electron impact ionization of C60, has been studied as a function of the electron energy and the time elapsed from ionization in a Nier type ion source/double focusing, sector-field mass spectrometer system.

TL;DR: Sharp peaks in the dissociative electron attachment (DEA) cross sections of uracil and thymine at energies below 3 eV are assigned to vibrational Feshbach resonances (VFRs) arising from coupling between the dipole bound state and the temporary anion state associated with occupation of the lowest sigma* orbital.

TL;DR: Cluster ions are a nonrigid assembly of components having properties between those of large gas phase molecules and the bulk condensed state as discussed by the authors, and they are used for fuel injection into fusion reactors and cluster ions are also present in other high-temperature systems such as those designed as sources of energy employing magnets and hydrodynamics.
