Carbon nanotubes are the strongest and stiffest materials yet discovered in terms of tensile strength and elastic modulus respectively. This strength results from the covalent sp 2 bonds formed between the individual carbon atoms. In 2000, a multi-walled carbon nanotube was tested to have a tensile strength of 63 gigapascals (9,100,000 psi).
NIST SRM 2483 is a soot of single-wall carbon nanotubes used as a reference material for elemental analysis, and was characterized using thermogravimetric analysis, prompt gamma activation analysis, induced neutron activation analysis, inductively coupled plasma mass spectroscopy, resonant Raman scattering, UV-visible-near infrared fluorescence ...
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 ...
BCN nanotube, composed of comparable amounts of boron, carbon, and nitrogen atoms [4] Boron nitride nanotube, a polymorph of boron nitride [5] [6] Carbon nanotube, includes general nanotube terminology and diagrams [7] DNA nanotube, a two-dimensional lattice which curves back upon itself, [8] somewhat similar in size and shape to a carbon nanotube
Researchers from Rice University and State University of New York – Stony Brook have shown that the addition of low weight % of carbon nanotubes can lead to significant improvements in the mechanical properties of biodegradable polymeric nanocomposites for applications in tissue engineering including bone, [6] [7] [8] cartilage, [9] muscle [10] and nerve tissue.
Proteins have high affinity to carbon nanotubes due to their diversity of amino acids being hydrophobic or hydrophilic. [6] Polysaccharides have been successfully been used to modify carbon nanotubes forming stable hybrids. [48] To make carbon nanotubes soluble in water, phospholipids such as lysoglycerophospholipids have been used. [49]

Graphenated carbon nanotubes (G-CNTs) are a relatively new hybrid that combines graphitic foliates grown along the sidewalls of multiwalled or bamboo style carbon nanotubes (CNTs). Yu et al. [ 1 ] reported on "chemically bonded graphene leaves" growing along the sidewalls of CNTs.
