Abstract
Air quality has direct effect on public health and life quality. Both gaseous and particulate pollutants affect the air quality. Aerosols, solid or liquid particles suspended in the air, play important roles in atmospheric sciences and air pollution. This course covers aerosol mechanical, optical and electrical properties, and measurement and control technologies.
Objective
The students understand the effects of airborne particulate and gaseous pollutants on air quality. The students gain fundamental knowledge on mechanics governing mechanical, optical and electrical properties of aerosols. Aerosol behaviors including diffusion, coagulation, condensation, charging and evaporation are discussed. The students understand basic principles to generate, sample, measure and control airborne particles. The students learn state-of-the-art instruments for air-borne particles from micrometer to nanometer size range.
