This scanning electron microscope image shows a wall of carbon nanotubes. Multiwalled carbon nanotubes are nested within each other. They exhibit extraordinary strength and unique electrical properties.
Multiwalled carbon nanotubes are actually tubes nested within tubes. These cylindrical carbon molecules have extraordinary strength and important electrical properties, making them potentially useful for many applications in electronics, optics, and other areas of materials science, as well as architectural fields.
The diameter of a nanotube is around 10 nm.
