Figure 1From: Comparative inhalation toxicity of multi-wall carbon nanotubes, graphene, graphite nanoplatelets and low surface carbon black Scanning electron microscopy images of the test materials. A-D: agglomerate scale, E-H: primary structure scale. A, E: MWCNT, B, F: graphene, C, G: graphite nanoplatelets, D, H: Carbon Black. Note the same scale for MWCNT and Carbon Black, and slightly different set of scales for graphite nanoplatelets and graphene, in order to point to their individual characteristics.Back to article page
