      Article first published online: 12 MAY 2015 | DOI: 10.1002/cctc.201500262

      Thumbnail image of graphical abstract

      Going around in circles: Opening of carbon nanotubes (CNTs) by using KMnO4 and H2SO4 leads to graphene nanoribbons that are full of metallic impurities from the synthesis of the CNTs and MnO2 from the opening of the CNTs.
