Others have proven theoretically that the Young’s modulus depends on the chirality and size of the SWNTs, ranging from 1.22 to 1.26 TPa. They have calculated a value of 1.09 TPa for a generic nanotube. However, when working with different MWNTs, others have noticed that the … WebThe chirality (or chiral vector) is very important because it determines the electronic properties of a CNT. CNTs can be classified into semiconducting and metallic depending …

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 this … See more 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 positions of … See more Narrowest examples If n and m are too small, the structure described by the pair (n,m) will describe a molecule that … See more 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 band gap can vary from zero to about 2 eV and the electrical conductivity can show metallic or … See more CNTs are known to have weak dispersibility in many solvents such as water as a consequence of strong intermolecular p–p interactions. This hinders the processability of CNTs in industrial applications. In order to tackle the issue, various … See more 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 … See more There is no consensus on some terms describing carbon nanotubes in scientific literature: both "-wall" and "-walled" are being used in combination with "single", "double", "triple", or "multi", and the letter C is often omitted in the abbreviation, for example, multi … See more Techniques have been developed to produce nanotubes in sizeable quantities, including arc discharge, laser ablation, chemical vapor deposition (CVD) and high-pressure carbon … See more WebThe effects of diameter and chirality on the thermal transport in free-standing and supported carbon-nanotubes Bo Qiu, Yan Wang, Qing Zhao, and Xiulin Ruana) School of Mechanical Engineering and the Birck Nanotechnology Center Purdue University West Lafayette, ...
