    For single-wall carbon nanotubes, ISO/TS 10868 describes a measurement method for the diameter, purity, and fraction of metallic nanotubes through optical absorption spectroscopy, [136] while ISO/TS 10797 and ISO/TS 10798 establish methods to characterize the morphology and elemental composition of single-wall carbon nanotubes, using ...

    Later, nanoindentations with atomic force microscope were performed by several groups to quantitatively measure radial elasticity of multiwalled carbon nanotubes [3] [4] and tapping/contact mode atomic force microscopy was also performed on single-walled carbon nanotubes. [5]

    A single-walled carbon nanotubes (SWCNT) can be envisioned as strip of a graphene molecule (a single sheet of graphite) rolled and joined into a seamless cylinder.The structure of the nanotube can be characterized by the width of this hypothetical strip (that is, the circumference c or diameter d of the tube) and the angle α of the strip relative to the main symmetry axes of the hexagonal ...

    en.wikipedia.org/wiki/Nanotube

    A nanotube is a nanoscale cylindrical structure with a hollow core, typically composed of carbon atoms, though other materials can also form nanotubes. Carbon nanotubes (CNTs) are the most well-known and widely studied type, consisting of rolled-up sheets of graphene with diameters ranging from about 1 to tens of nanometers and lengths up to ...

    Carboxyl-modified single-walled carbon nanotubes (so called zig-zag, armchair type) can act as sensors of atoms and ions of alkali metals Na, Li, K. [168] In May 2005, Nanomix Inc. placed on the market a hydrogen sensor that integrated carbon nanotubes on a silicon platform.

  7. Single-walled carbon nanohorn - Wikipedia

    en.wikipedia.org/wiki/Single-walled_carbon_nanohorn

    Single-walled carbon nanohorn (SWNH or SWCNH) is the name given by Sumio Iijima and colleagues in 1999 to horn-shaped sheath aggregate of graphene sheets. [ 1 ] [ 2 ] Very similar structures had been observed in 1994 by Peter J.F. Harris, Edman Tsang, John Claridge and Malcolm Green . [ 3 ]

    A particular case of non-covalent modification is the formation of rotaxane-like mechanically interlocked derivatives of single-walled nanotubes (SWNTs). [51] In this strategy, the SWNTs are encapsulated by molecular macrocycle(s), which are either formed around them by macrocyclization, [52] [53] or pre-formed and threaded at a later stage. [54]

  9. Selective chemistry of single-walled nanotubes - Wikipedia

    en.wikipedia.org/wiki/Selective_chemistry_of...

    Nanotubes reacted with the diazonium reagent can be converted back into pristine nanotubes when thermally treated at 300 °C in an atmosphere of inert gas. This cleaves the aryl hydroxyl moieties from the nanotube sidewall and restores the spectroscopic feature (Raman and absorption spectra) of pristine nanotube.
