Are soot particles really spherical?
Soot, like the greenhouse gases, is an important contributor to global warming. It is a major constituent of the atmosphere through emissions from industry, automobiles, and biomass burning. Its radiative properties depend strongly on its shape. All current climate models assume it forms in spherical particles, but does it really? The group of ASU Professor Buseck is using advanced methods of electron microscopy to determine the 3-dimensional shapes of nanoparticles like soot and evaluate their effects on climate and climate change.
