Espectroscopia optogalvânica: alguns aspectos relevantes

open access: yesQuímica Nova, 2006
In this work we present the optogalvanic effect in ionized gases in an historical perspective. This effect was observed for the first time by Foote and Mohler in 1925, and explained by Penning in 1928 for mixtures (Ne-Ar) and pure gases (or vapours) in ...

Ionization in Gases by Ions and Atoms [PDF]

open access: yesProceedings of the National Academy of Sciences, 1932
It has been assumed for a long time that the ionization of atoms by ions must in one form or another play an important role in the phenomena of gas discharges. This assumption found its mathematical expression in the well-known theory of Townsend.

Guest editorial: special issue on nonthermal medical/biological applications using ionized gases and electromagnetic fields

open access: yes, 2006
Introduction: The fascination of men with the interaction between electricity and biological systems can be traced back to Egyptian hieroglyphs dated in 4000 BC that describe biological electricity in catfish.

Transport phenomena in neutral and ionized gases [PDF]

open access: yes, 2017
Transport processes in gases are examined from both the point of view of non-equilibrium thermodynamics and kinetic theory. Thermodynamics is used to establish concise representations of the general properties of transport coefficients, and in ...

Influence of Nitrogen Admixture on Plasma Characteristics in a dc Argon Glow Discharge and in Afterglow

open access: yesAtoms, 2019
The present paper is based on the materials of the Invited Lecture presented at 29th Summer School and International Symposium on the Physics of Ionized Gases (28 August 2018–1 September 2018, Belgrade, Serbia). In the paper, the effect of nitrogen

Collisional and viscous damping of MHD waves in partially ionized plasmas of the solar atmosphere [PDF]

open access: yes, 2004
Magnetohydrodynamic (MHD) waves are widely considered as a possible source of heating for various parts of the outer solar atmosphere. Among the main energy dissipation mechanisms which convert the energy of damped MHD waves into thermal energy are ...

Spatial Distribution of H2O+ Ions in the Inner Coma of C/2014 Q2 (Lovejoy)

open access: yesThe Astrophysical Journal
Neutral molecules that sublimate from cometary ices (mainly water at ∼1 au from the Sun) are ionized due to solar extreme-ultraviolet radiation and collisions with highly energetic electrons.
