New Imaging Tool Photo of Nanotubes (image) Purdue University Caption Metallic and semiconducting single-wall carbon nanotubes are distinguished using a new imaging tool for rapidly screening the structures. The technology may hasten the use of nanotubes in creating a new class of computers and electronics that are faster and consume less power than those in use today.
