  2. Vertically aligned carbon nanotube arrays - Wikipedia

    en.wikipedia.org/wiki/Vertically_aligned_carbon...

    Hata et al. reported millimeter-scale vertically aligned 2.5 mm long SWCNTs using the water assisted ethylene CVD process with Fe/Al or aluminum oxide multilayers on Si wafers. [17] It was proposed that controlled supply of steam into the CVD reactor acted as a weak oxidizer and selectively removed amorphous carbon without damaging the growing ...

  3. Vantablack - Wikipedia

    en.wikipedia.org/wiki/Vantablack

    Vantablack grown on metal foil. CVD Vantablack is composed of a forest of vertical carbon nanotubes "grown" on a substrate using a modified chemical vapor deposition process. When light strikes Vantablack, instead of bouncing off, it becomes trapped and continually deflected amongst the tubes, absorbed, and eventually dissipated as heat. [24]

  4. Carbon nanotube - Wikipedia

    en.wikipedia.org/wiki/Carbon_nanotube

    One problem of CVD processes is the high variability in the nanotube's characteristics [97] The HiPCO process advances in catalysis and continuous growth are making CNTs more commercially viable. [98] The HiPCO process helps in producing high purity single-walled carbon nanotubes in higher quantity.

  5. Chemical vapor deposition - Wikipedia

    en.wikipedia.org/wiki/Chemical_vapor_deposition

    CVD is commonly used to deposit conformal films and augment substrate surfaces in ways that more traditional surface modification techniques are not capable of. CVD is extremely useful in the process of atomic layer deposition at depositing extremely thin layers of material. A variety of applications for such films exist.

    Former President Jimmy Carter, honored more widely for his humanitarian work around the globe after his presidency than for his White House tenure during a tumultuous time, has died.He was 100 ...

  7. Synthesis of carbon nanotubes - Wikipedia

    en.wikipedia.org/wiki/Synthesis_of_carbon_nanotubes

    CVD is the most widely used method for the production of carbon nanotubes. [21] For this purpose, the metal nanoparticles are mixed with a catalyst support such as MgO or Al 2 O 3 to increase the surface area for higher yield of the catalytic reaction of the carbon feedstock with the metal particles.
