. Aerodynamic particle size distributions by number (provided by the ELPI and APS) for several materials with increasing D resp/D tot. Particle number concentrations have been peak-normalized (hence arbitrary units). The materials are ordered (top through bottom with increasing D resp/D tot) by nanoclays PGV and PGN, Holland Lactose, Mitsui VII MWCNT, Pyrograph III CNF, Printex 90 Carbon Black, Arizona Road Dust, Aerosil 50 OX fumed SiO2, and HiPCO SWCNT.
