Time and Location: Periods 7-8, BLK 315

Aerosols, which are particles suspended in air, are omnipresent. Examples include:

· smoke from power generation, cigarette, forest fire, diesel engine;

· atmospheric aerosols causing reduced visibility, polar ozone depletion; rain, snow, cloud, fog;

· inhalation of particles containing toxic metals, PAH or biological agents

· respiratory care; drug delivery through respiratory system;

· production of carbon black, pigment, dispersant, catalyst

Certain aerosols cause significant health and environmental problems while others improve the quality of our life. To prevent the formation of undesired pollutants or to produce materials of desired properties, it is important to understand the mechanics of aerosols. In this course, the following topics will be covered to help you understand fundamental aerosol mechanics so that you can “manipulate” your aerosols:

· Single Particle Characterization; Aerosol Population Statistics; Moment

· Transport Properties: Inertial Impaction, Diffusion, Electrical Migration, Thermophoresis

· Optical Properties

· Aerosol Dynamics: Coagulation, Condensation, Nucleation, Sintering, GDE

· Aerosol Instrumentation: Measurement, Sampling & Generation

· Applications: Bioaerosol, Atmospheric Aerosol, Respiratory Deposition, Material Synthesis, Ambient Sampling, High-Temperature Sampling, Radioactive Aerosol
