The propagation of arbitrary amplitude dust ion acoustic waves (DIAWs) in a magnetized collisional dusty plasma including hot electrons, with kappa velocity distribution for electrons, warm ions and dust particles has been studied. In the presence of immobile massive dust particulates, DIAWs have been investigated through the Sagdeev pseudo-potential method. It is demonstrated that the amplitud...

The oblique propagation of arbitrary ion acoustic solitary waves (IASWs) in magnetized electron-positron-ion plasmas is investigated by employing Sagdeev pseudopotential approach. Ions are assumed to be adiabatic having anisotropic thermal pressure. Electrons and positrons considered isothermal, following Maxwellian distribution. In terms electrostatic potential, potential function obtained ana...

Abstract Using Sagdeev potential approach the modified Bohm’s criterion is evaluated for magnetized electronegative warm plasma containing secondary electrons. Dependency of Bohm velocity on electrons, inclination angle magnetic field, collisionality, electronegativity and temperature ratio (electron to positive ions) are examined. found be independent magnitude field but depends its incidence ...

Renad Sagdeev stands in a tradition of great Russian scientists in magnetic resonance and the chemistry of free radicals. He was a student of Yuri Molin, who himself had done his PhD with V.V. Voevodsky, one of the early leaders of the Institute of Chemical Kinetics and Combustion (ICK&C) in Novosibirsk. Voevodsky, in turn, came from the school of the famous scientist and Nobel laureate N.N. Se...

The effects of magnetic fields on chemical reactions have been the subject of several review articles in recent years (Atkins, 1976; Atkins and Lambert, 1975; Sagdeev et al., 1977b; Lawler and Evans, 1971 ; Turro and Kraeutler, 1980; Turro, 1983). It is the object of the present review to describe the current theory and to illustrate, with examples, the changes that arise in the formation of pr...
