"Nano- and Microscale Particles in Natural Phenomena and Plasmas"
(Studies at the Institute for Dynamics of Geospheres RAS)

Professor S.I. Popel (Institute for Dynamics of Geospheres RAS)

Abstract:

A review of the results of investigations carried out at the Institute for Dynamics of Geospheres RAS and devoted to nano- and microscale particles in natural phenomena and plasmas is presented. In particular, the cavitation mechanism of formation of nano- and mirospherules in Earth's crust, processes of formation of nano- and miroscale particles in human environment, in Earth's atmosphere and ionosphere, and in space are discussed. An emphasis is given to nano- and miroscale particles in chemical explosions, in rockfalls and rockslides, in the processes of formation of noctilucent clouds and polar mesosphere summer echoes, in the processes accompanying an impact of a meteoroid with an atmosphereless cosmic body, etc. The influence of charged nano- and miroscale particles on the formation and evolution of perturbations in laboratory and ionospheric plasmas is discussed.
