TL;DR: In this article, different characteristics of ion acoustic waves were experimentally observed in two types of Xe+−F− double plasmas at different electron temperatures, and the slow mode, which had been considered not to dominate the wave propagation, was observed to be dominant for the higher electron temperature (around 1.5 eV).

TL;DR: In this article, cross section data are compiled from the literature for electron collisions with methane (CH4) molecules and cross sections are collected and reviewed for total scattering, elastic scattering, momentum transfer, excitations of rotational and vibrational states, dissociation, ionization, and dissociative attachment.

TL;DR: In this article, the authors investigated the role of charged dust particles in the ion sheath structure of a double-plasminar device and found that the average charge on a dust grain decreases when dust density in the plasma volume is increased.

TL;DR: In this paper, the influence of ion beam and charged dust impurity on the propagation of dust ion-acoustic (DIA) solitary wave (SW) in an unmagnetized plasma consisting of Boltzmann distributed electrons, positive ions, positive ion beam, and negatively charged immobile dusts in a double plasma device was studied.
