2. OCSiAl - Wikipedia

   en.wikipedia.org/wiki/OCSiAl

   OCSiAl owns the only scalable technology that can synthesize graphene nanotubes (also known as single wall carbon nanotubes – SWCNTs) in industrial volumes. [1] [2] The technology is notable for producing SWCNTs in large quantities (tonnes) to enable low enough pricing for industrial applications to become economically feasible.

3. Carbon nanotube - Wikipedia

   en.wikipedia.org/wiki/Carbon_nanotube

   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 ...

4. Selective chemistry of single-walled nanotubes - Wikipedia

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

   This is a fast, selective noncovalent adsorption and diazonium group in this complex partially dopes the nanotube, diminishing the tangential mode in the Raman spectrum. Desorption of A from nanotube is negligible (k −1 ~ 0). In second step complex B then decomposes to form a covalent bond with the nanotube surface.

5. Optical properties of carbon nanotubes - Wikipedia

   en.wikipedia.org/wiki/Optical_properties_of...

   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 ...

6. Single-walled carbon nanohorn - Wikipedia

   en.wikipedia.org/wiki/Single-walled_carbon_nanohorn

   Included in this family are single-walled and multi-walled carbon nanotubes (SWNTs and MWNTs), [5] carbon onions and cones and, most recently, SWNHs. These SWNHs with about 40–50 nm in tubule length and about 2–3 nm in diameter are derived from SWNTs and ended by a five-pentagon conical cap with a cone opening angle of ~20 o .

7. Potential applications of carbon nanotubes - Wikipedia

   en.wikipedia.org/wiki/Potential_applications_of...

   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.
