Structural and Dynamic Phenomena in the 'Plasma Kristall-4' Experiments under Microgravity Conditions.

New results from the recent experiments using the 'Plasma Kristall-4', 'PK-4', onboard of the parabolic flight plane A-300 Zero-G are presented. These are: a) structural and dynamics properties of dusty plasma clouds containing elongated dust particles-microrods; b) formation of a boundary-free dust cluster due to attractive forces caused by ion fluxes in a bulk plasma region; c) shock wave in dusty plasma driven by the electrical manipulative electrode in polarity switching direct current discharge. Physical models of the observed phenomena are presented and discussed. Universal possibilities of the 'PK-4' setup are demonstrated. [ABSTRACT FROM AUTHOR]
