Planetary Nebulae and the Ionization of the Interstellar Medium in Galaxies
Frontiers in Astronomy and Space Sciences, 2022 We discuss the role of planetary nebulae and their progeny in galaxy context in terms of ionization of the galaxy interstellar medium. This regards ionized gas outside the disk of spiral galaxies, the diffuse ionized medium in spiral galaxies, and the ...

Ambient Ionization Mass Spectrometry for Point-of-Care Diagnostics and Other Clinical Measurements.
Clinical Chemistry, 2016 BACKGROUND One driving motivation in the development of point-of-care (POC) diagnostics is to conveniently and immediately provide information upon which healthcare decisions can be based, while the patient is on site.

Mathematical Physics, Analysis and Geometry, 2004 In the context of an idealized model describing an atom coupled to black-body radiation at a sufficiently high positive temperature, we show that the atom will end up being ionized in the limit of large times. Mathematically, this is translated into the statement that the coupled system does not have any time-translation invariant state of positive ...

Ionization Cross Sections in the Collision between Two Ground State Hydrogen Atoms at Low Energies
Atoms, 2020 The interaction between two ground state hydrogen atoms in a collision was studied using the four-body classical trajectory Monte Carlo method. We present the total cross sections for the dominant channels, namely for the single ionization of the target,

Burns by Ionizing and Nonionizing Radiation
Journal of Burn Care & Research, 2020 Abstract This article consists of the study and investigative analysis of the effects of burns by radiation in humans. Cases of nuclear accidents, such as Chernobyl (ionizing radiation) and the effects of nonionizing radiation, such as infrared and microwave radiation are detailed here.

Separation of ions with the same charge to mass ratio from a collision experiment [PDF]
Journal of the Serbian Chemical Society, 2000 Some atomic collision experiments lead to ions having identical q/m ratio, as well as average velocity, so that standard electric and magnetic analyzers are not able to identify them separately.

High-order harmonic spectroscopy in an ionized high-density target
Frontiers in Physics, 2022 We use high-order harmonic spectroscopy to study ionization dynamics in a macroscopic target with tunable density, spanning over six orders of magnitude.

Think Negative: Finding the Best Electrospray Ionization/MS Mode for Your Analyte.
Analytical Chemistry, 2017 For the first time, the electrospray ionization efficiency (IE) scales in positive and negative mode are united into a single system enabling direct comparison of IE values across ionization modes. This is made possible by the use of a reference compound
