Arc-produced short-length multi-walled carbon nanotubes as “millstones” for the preparation of graphene-like nanoplatelets
Kostoglou, Nikolaos; Ryzhkov, Vladislav; Walters, Ian; Doumanidis, Charalabos; Rebholz, Claus; Mitterer, Christian (2019)Naturally short-length multi-walled Russian-doll-like carbon nanotubes derived by a catalyst-free arc-discharge method were used as nano-sized “cutters” to transform bulk graphitic sheets into thin/few-layered graphene-like ...
