Detailed explanation-1: -It is the carbon nanotube, a new form of carbon discovered in 1991. The nanotube is a molecular cousin of a form of carbon that is perhaps more familiar, the C60 molecule or buckyball, an array of 60 carbon atoms forming a soccer-ball-like icosahedron.
Detailed explanation-2: -What are carbon nanotubes? Carbon nanotubes (CNTs) are cylindrical molecules that consist of rolled-up sheets of single-layer carbon atoms (graphene).
Detailed explanation-3: -Carbon nanotubes (CNTs) are cylindrical large molecules consisting of a hexagonal arrangement of hybridized carbon atoms, which may by formed by rolling up a single sheet of graphene (single-walled carbon nanotubes, SWCNTs) or by rolling up multiple sheets of graphene (multiwalled carbon nanotubes, MWCNTs).
Detailed explanation-4: -Carbon nanotubes, also called buckytubes, are nanoscale hollow cylindrical molecules (tubes) (Fig. 4). They consist of rolled-up sheets of graphene (Dresselhaus et al., 2004) in which a single layer of carbon atoms is arranged in a hexagonal lattice.
