Figure 1: TEM micrographs of the particle samples. Micrographs of CNF A (a), CNF B (b), CNF C (c), CNF D (d), swCNT (e), and mwCNT (f) illustrate the difference in width and length between the CNF and CNT. Examples of metallic particle presence are indicated by dense arrows. Most metallic particles are embedded in the carbon material. Shorter fragments of fibers are indicated by dotted arrows.
