“…[10][11][12][13] These points are discussed in recent works published by some of the present authors. [12,13] On the other hand, several books on the nonequilibrium vibrational kinetics [14][15][16] as well as of plasmachemistry [17,18] and collisional-radiative models [19] can be used to construct accurate non-equilibrium plasma kinetic models. Apparently, all has been already developed in these topics, though even nowadays the Maxwell distribution function for eedf and Boltzmann distributions for vibrational and electronic states of the different species are widely used.…”

The coupling between the electron energy distribution function (eedf) and the kinetics of vibrationally and electronically excited states is discussed. The first case study concerns the role of heterogeneous recombination in affecting the concentration of atomic hydrogen in RF plasmas, with consequences on eedf and negative ion formation. The coupling of eedf and a collisional‐radiative model for atomic hydrogen is discussed for optically thin and thick plasmas, finding large differences in the creation of eedf plateaux. The last case study deals with a self‐consistent coupling of eedf and kinetics of vibrationally and electronically excited states in CO2 cold plasmas emphasizing the role of pure vibrational mechanisms in the dissociation of CO2.

“…The mixtures are assumed enough rarefied to be treated as ideal gases and to be described in terms of single-particle distribution functions even after multiple ionization steps. Under these conditions one can use the generalized Boltzmann equations like it was done for the description of gas mixtures with excitation of molecular internal degrees of freedom and chemical reactions [see, for example, (Loureiro and Amorim, 2016;Ferziger and Kaper, 1972;Vallander et al, 1977;Giovangigli, 1999;Rydalevskaya, 2003;Nagnibeda and Kustova, 2009;Loureiro and Amorim, 2016)].…”

Model kinetic equations are proposed for the description of ionized monoatomic gas mixture flows. The mixtures are assumed enough rarefied to be treated as ideal gases after multiple ionization steps. The model equations contain the equilibrium distribution functions for the components of the gas mixtures under consideration like it was done in BGK equations and their well-known generalizations. However, in this paper the new forms of the equilibrium distribution functions are used which correspond to the entropy maximum under the constraints of momentum, total energy, nuclei and electrons (both bound and free) conservation. It is shown that the derived model equations allow us to study the local equilibrium flows of the ionized gases and the transport processes of energy, nuclei and electrons in the non-equilibrium conditions.

“…The adhesive forces bonding is a key joining technology in many manufacturing areas which include the automotive and aerospace industries, adding to biomedical and microelectronics applications [16]. The reactive species (electrons, atomic or molecular ions, atoms or molecules energetically excited) in the cold plasma can modify the superficial functional characteristics of the target material and promote the surface functionalization reactions by generating organic or inorganic thin layers because of the recombination of radicals or molecular fragments species on the surfaces of this material [17] [18] [19].…”

The (DC-GDPAU) is a DC glow discharge plasma experiment that was designed, established, and operated in the Physics Department at Ain Shams University (Egypt). The aim of this experiment is to study and improve some properties of a printed circuit board (PCB) by exposing it to the plasma. The device consists of cylindrical discharge chamber with movable parallel circular copper electrodes (cathode and anode) fixed inside it. The distance between them is 12 cm. This plasma experiment works in a low-pressure range (0.15-0.70 Torr) for Ar gas with a maximum DC power supply of 200 W. The Paschen curves and electrical plasma parameters (current, volt, power, resistance) characterized to the plasma have been measured and calculated at each cm between the two electrodes. Besides, the electron temperature and ion density are obtained at different radial distances using a double Langmuir probe. The electron temperature (KT e) was kept stable in range 6.58 to 10.44 eV; whereas the ion density (n i) was in range from 0.91 × 10 10 cm −3 to 1.79 × 10 10 cm −3. A digital optical microscope (800×) was employed to draw a comparison between the pre-and after effect of exposure to plasma on the shaping of the circuit layout. The experimental results show that the electrical conductivity increased after plasma exposure, also an improvement in the adhesion force in the Cu foil surface. A significant increase in the conductivity can be directly related to the position of the sample surfaces as well as to the time of exposure. This shows the importance of the obtained results in developing the PCBs manufacturing that uses in different microelectronics devices like those onboard of space vehicles.
