Nanoparticle morphology. Section profiles (transects) of TiO2 nanoparticles collected from the aerosol on filters, embedded in Epon and cut perpendicularly to the filter. Note that the as 20 nm measured TiO2 aerosol particles are already agglomerates of smaller primary particle structures of 3 - 5 nm formed immediately after spark ignition and condensation. Bar: 200 nm.
