  • Coated vertically aligned carbon nanotubes on nickel foam
    Patent number: 11929504
    Abstract: Vertically aligned carbon nanotubes (VACNTs) (e.g., multi-walled VACNTs and methods of synthesizing the same are provided. VACNTs can be synthesized on nickel foam (Ni—F), for example by using a plasma-enhanced chemical vapor deposition (PECVD) technique. A wet chemical method can then be used to coat on the VACNTs a layer of nanoparticles, such as tin oxide (SnO2) nanoparticles.
    Type: Grant
    Filed: October 7, 2022
    Date of Patent: March 12, 2024
    Assignee: THE FLORIDA INTERNATIONAL UNIVERSITY BOARD OF TRUSTEES
    Inventors: Wenzhi Li, Arun Thapa

  • COPPER-FILLED CARBON NANOTUBES AND SYNTHESIS METHODS THEREOF
    Publication number: 20220024768
    Abstract: Copper-filled carbon nanotubes and methods of synthesizing the same are provided. Plasma-enhanced chemical vapor deposition can be used to synthesize vertically aligned carbon nanotubes filled with copper nanowires. The copper filling can occur concurrently with the carbon nanotube growth, and the carbon nanotubes can be completely filled by copper. The filling of Cu inside the CNTs can be controlled by tuning the synthesis temperature.
