Tags: carbon nanotubes


100 amps of electricity crackle in a vacuum chamber, creating a spark that transforms carbon vapor into tiny structures. Depending on the conditions, these structures can be shaped like little, 60-atom soccer balls, or like rolled-up tubes of atoms, arranged in a chicken-wire pattern, with rounded ends. These tiny, carbon nanotubes, discovered by Sumio Iijima at NEC labs in 1991, have amazing properties. They are 100 times stronger than steel, but weigh only one-sixth as much. They are incredibly resilient under physical stress; even when kinked to a 120-degree angle, they will bounce back to their original form, undamaged. And they can carry electrical current at levels that would vaporize ordinary copper wires.

  2. Nature of Single-Walled Carbon Nanotubes' Interactions with Differing Photosensitizers

    31 Aug 2023 | | Contributor(s):: Rubiona Grainger, Nima Soltani, Rice University

    It was recently discovered that when Single-Walled Carbon Nanotubes (SWCNTs) wrapped with single-stranded DNA are exposed to singlet oxygen the singlet oxygen reacts with the guanine nucleotides embedded in the DNA. The singlet oxygen is produced by irradiation of a photosensitizer. However,...
