Graphene as a basic building block for graphitic materials of all other
dimensionalities. It can be wrapped up into 0-dimensional fullerenes, rolled into
1-dimensional nanotubes or stacked into 3-dimensional graphite. Reprinted from [54],

of graphene's applications includes: nanoelectronics [63], structural com-
posites [64], conducting polymers [64], battery electrodes [65,66], super-
capacitors [67], transport barriers [68,69], printable inks [70], antibacterial
papers [67], and biomedical technologies [71,72].
More recently, the multifarious applications of graphene have encour-
aged not only the development of substrate-bound extended graphene
