Nano-abacus

The nano-abacus is a nano-sized abacus developed by IBM scientist. Stable rows made up of ten molecules act as the railings of the abacus. The beads are made up of fullerene and are pushed around by a scanning tunneling microscope tip. The nano-abacus has the potential to be used in a variety of nanotechnological inventions such as the nano-computer. [1]
