Brief Bio:
Sumio Iijima was born in Japan in 1939, and was educated at the University of Electro-Communications in Tokyo. After completing his Ph.D. in physics at Tohoku University in Sendai, he moved to Arizona State University in Phoenix, Arizona. There, in postdoctoral research and later as a research scientist from 1970 to 1982, he worked on high resolution electron microscopy. He revealed the first electron micrograph showing atoms in a crystal. Dr. Iijima also worked as a visiting scholar at Cambridge University in 1979, where he carried out electron microscopy of graphite. He moved back to Japan in 1982 to join the ERATO ultrafine particles project, where he succeeded in a dynamic observation on metal clusters. Dr. Iijima has been a research fellow at NEC since 1987 and discovered carbon nanotubes in 1991. He is a recipient of the 1996 Asahi Award. He has received also the Nishina Memorial Award, B. E. Warren Award and several others. Inspired by the discovery of fullerenes (for which the 1996 Nobel chemistry was awarded), Dr. Iijima discovered tiny tubules with a diameter as small as 0.8 nanometers, now known as carbon nanotubes. By further discovering a technique to insert metal into the hollow of carbon nanotubes, Dr. Iijima created what could be the tiniest wire ever made and has attracted considerable attention from the scientific community.
