Nanotube production

A carbon nanotube (CNT) is a tube made of carbon with diameters typically measured in nanometers. Single-wall carbon nanotubes (SWCNTs) are one of the allotropes of carbon, intermediate between fullerene cages and flat graphene, with diameters in the range of a nanometre. Although not made … Zobacz więcej Basic details The structure of an ideal (infinitely long) single-walled carbon nanotube is that of a regular hexagonal lattice drawn on an infinite cylindrical surface, whose vertices are the … Zobacz więcej Narrowest examples If n and m are too small, the structure described by the pair (n,m) will describe a molecule that … Zobacz więcej Many properties of single-walled carbon nanotubes depend significantly on the (n,m) type, and this dependence is non-monotonic (see Kataura plot). In particular, the Zobacz więcej CNTs are known to have weak dispersibility in many solvents such as water as a consequence of strong intermolecular … Zobacz więcej the structure of the nanotube is not changed if the strip is rotated by 60 degrees clockwise around A1 before applying the hypothetical reconstruction above. Such a rotation changes the corresponding pair (n,m) to the pair (−2m,n+m). It … Zobacz więcej There is no consensus on some terms describing carbon nanotubes in scientific literature: both "-wall" and "-walled" are being used in … Zobacz więcej Techniques have been developed to produce nanotubes in sizeable quantities, including arc discharge, laser ablation, chemical vapor deposition (CVD) and high-pressure carbon monoxide disproportionation (HiPCO).
