Silicon microspheres have extraordinary mechanical strength due to the addition of carbon nanotubes which make the spheres resemble balls of yarn. In this representation, the image on the left illustrates a close-up of a portion of a microsphere made of silicon nano particles deposited on carbon nanotubes.
