  2. Mechanical properties of carbon nanotubes - Wikipedia

    en.wikipedia.org/wiki/Mechanical_properties_of...

    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).

  3. Potential applications of carbon nanotubes - Wikipedia

    The exceptional electrical and mechanical properties of carbon nanotubes have made them alternatives to the traditional electrical actuators for both microscopic and macroscopic applications. Carbon nanotubes are very good conductors of both electricity and heat, and they are also very strong and elastic molecules in certain directions.

  4. Carbon nanotube - Wikipedia

    Spectroscopic methods offer the possibility of quick and non-destructive characterization of relatively large amounts of carbon nanotubes. There is a strong demand for such characterization from the industrial point of view: numerous parameters of nanotube synthesis can be changed, intentionally or unintentionally, to alter the nanotube quality ...

    Because of their tube structure, carbon nanotubes can be made with or without end caps, meaning that without end caps the inside where the drug is held would be more accessible. Right now with carbon nanotube drug delivery systems, problems arise like the lack of solubility, clumping occurrences, and half-life. [8]

  6. Virus nanotechnology - Wikipedia

    en.wikipedia.org/wiki/Virus_nanotechnology

    Virus nanotechnology is the use of viruses as a source of nanoparticles for biomedical purposes. Viruses are made up of a genome and a capsid; and some viruses are enveloped. Most virus capsids measure between 20-500 nm in diameter. Because of their nanometer size dimensions, viruses have been considered as naturally occurring nanoparticles.

  7. Carbon nanotube chemistry - Wikipedia

    en.wikipedia.org/wiki/Carbon_nanotube_chemistry

    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]

    Animal studies indicate that carbon nanotubes and carbon nanofibers can cause pulmonary effects including inflammation, granulomas, and pulmonary fibrosis, which were of similar or greater potency when compared with other known fibrogenic materials such as silica, asbestos, and ultrafine carbon black.

  9. Selective chemistry of single-walled nanotubes - Wikipedia

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

    Consequently, nanotubes are expected to be less reactive than most fullerene molecules due to their smaller curvature, but more reactive than a graphene sheet due to pyramidalization and misalignment of pi-orbitals. The strain of a carbon framework is also reflected in the pyramidalization angle (Ө p) of the carbon constituents.
