Laser Probes Microscopic Components of Air Pollution
Researchers at the U.S. Department of Energy?s SLAC National Accelerator Laboratory have captured the most detailed images to date of airborne soot particles, a key contributor to global warming and a health hazard. The discovery reveals the particles' surprisingly complex nanostructures and could ultimately aid the understanding of atmospheric processes important to climate change, as well as the design of cleaner combustion sources, from car engines to power plants. This short conceptual animation depicts how the scientists can simultaneously capture fractal morphology (structure), chemical composition, and nanoscale imagery of individual aerosol particles in flight.
