Atmospheric aerosol particles formed from volatile organic compounds most likely exist as glassy, amorphous solids, rather than as liquid droplets, according to an international group of researchers led by Annele Virtanen of Tampere University of Technology, in Finland, and Thomas Koop of Bielefeld University, in Germany (Nature 2010, 467, 824). Aerosols play a role in Earth’s climate by scattering radiation and acting as cloud-condensation nuclei. Determining their physical state is important . . .
