Abstract:

A stereo-ultramicroscope is described, designed for studying the mechanical and electrical state of sub-micron aerosols. With this an attempt is made to answer the question do collisions between particles of sub-micron aerosols occur and do they result in coagulation. Observations of many sub-micron aerosols, solid or liquid particles, charged or uncharged, failed to reveal any collisions and coagulation. A possible reason explaining these observations is discussed. Author
