ABSTRACT
Among the numerous carbon nanostructures that have been deeply investigated in universities and research centers over the past few decades-e.g., nanodiamonds, fullerenes, nanotubes, graphene, nanofibers, and nanohorns-carbon nanotubes (CNTs) are perhaps the most studied ones after graphene. Indeed, after Iijima’s landmark publication in 1991 (Iijima 1991), numerous experiments have been carried out to understand and disclose their remarkable chemical and physical properties, arising from the nanoscale dimension and the quasi-one-dimensional (1D) periodicity (Ajayan 1999; Dresselhaus et al. 2001; Dai 2002).
