Aerosol Science is about the properties and behavior of particles suspended in a gaseous medium. In the 3-credit course of Aerosol Science, several topics will be covered , including aerosol size distribution, properties of gases, particle Kinetics and Brownian diffusion, particle motion under external forces, optical properties, and particle growth by coagulation, condensation and nucleation. Besides, the applications of Aerosol Science will be discussed especially in the fields of manufacturing processes, environmental aspects, and industrial hygiene.
