| Abstract: | Conclusions Hydrophobic and tight coatings are recognized by the comparison of the condensation properties of the pure materials of the same electrical mobility diameter. A shift to higher supersaturations necessary for activation is then observed.The consequences drawn for the atmosphere are: Residence time of suspended ultrafine matter is substantially increased, because of the less effective scavenging process.
