	Sumio Iijima - Wikipedia, the free encyclopedia
		Sumio Iijima (飯島澄男 Iijima Sumio, born May 2, 1939) is a Japanese physicist, best known for discovering carbon nanotubes in 1991.
		Born in Saitama Prefecture in 1939, Iijima graduated with a Bachelor of Engineering degree in 1963 from the University of Electro-Communications, Tokyo.
		He was awarded the Benjamin Franklin Medal in Physics in 2002, "for the discovery and elucidation of the atomic structure and helical character of multi-wall and single-wall carbon nanotubes, which have had an enormous impact on the rapidly growing condensed matter and materials science field of nanoscale science and electronics."

		Sumio Iijima, a scientist at NEC Corporation, made the discovery this past May while examining sooty deposits on a carbon-arc electrode he had used to generate fullerenes.
		Iijima deduced the structure of his tubes in part from images produced by the 500,000-fold magnifications of a high-resolution transmission electron microscope, in part from electron diffraction patterns.
		Iijima says he is trying to optimize for length and for yield, but he just laughs when asked how he hopes to do it and what results he expects to obtain.

		Iijima and his research team realized nanohorns could serve as electrodes in fuel cells, where a hydrogen-based fuel such as methanol is catalytically converted into energy.
		Iijima also teaches at Meijo University in Nagoya, directs the Research Center for Advanced Carbon Materials at the National Institute of Advanced Industrial Science and is the research director of a nanotechnology project at the International Cooperative Research Project at the Japan Science and Technology Corp.

		Sumio Iijima was considered the strongest among the Japanese candidates for the prize.
		This is because Iijima is known for his 1991 discovery of the carbon nanotube, an ultrafine carbon material measuring several thousandths of a human hair in diameter.
		Iijima failed to be chosen as Nobel laureate this year, many experts say he most likely will win the Nobel Prize in the next few years.

		Iijima is currently taking a global leading role as a Representative Researcher in the International Cooperative Research Project "Nanotubulites " of Japan Science and Technology Corporation (ICORP/JST).
		Iijima clarified mechanisms of growth and bending of nanotubes, found metal incorporation into nanotubes, and grew single-wall carbon nanotubes.
		The technology is almost in practical use in the flat panel display industry and in the future, because of its crystal completeness and miniature structure, carbon nanotube technology is expected to be applied to fuel cells, catalysts, absorbents, sensors, STM probes, lightweight and high-strength raw material and medicine etc.

		Iijima's samples were created by a direct-current arc discharge between carbon electrodes immersed in a noble gas.
		Iijima himself suggests that nanotubes may have been formed in those old experiments, but Bacon lacked the high-power microscope required to see them.
		Although various fullerenes can be produced by different ways of vaporizing carbon, followed by condensation in tiny clusters, the presence of an electric field in the arc discharge seems to promote the growth of the long tubules.

		Over the past year, he and his team at NEC have used nanotubes as a component in hydrogen-powered fuel cells that could prove to be the key energy source for automobiles in the future.
		At his admissions interview, the Tohoku professors decided to place Iijima in the microscopy lab, where research into the atomic structure of materials is conducted using high-resolution electron microscopes.
		Iijima adopted the same method used to create C60 in his nanotube experiments: He passed electrical sparks between two graphite rods.

		Buckyballs are nanometer-sized spheres with 60 carbon atoms in the exact shape of a soccer ball.
		When Dr. Iijima looked under a microscope at the soot this process produced, he noticed "whiskers," which he later discovered to be tubes -- carbon nanotubes!

		They were discovered in 1991 by the Japanese electron microscopist Sumio Iijima who was studying the material deposited on the cathode during the arc-evaporation synthesis of fullerenes.
		A short time later, Thomas Ebbesen and Pulickel Ajayan, from Iijima's lab, showed how nanotubes could be produced in bulk quantities by varying the arc-evaporation conditions.
		Sumio Iijima's group subsequently showed that they could also be produced by laser ablation of graphite, and gave them the name "nanohorns".

		Luck favours the prepared mind, as Louis Pasteur said, and Japanese scientist Sumio Iijima’s mind was certainly well prepared for his amazing discovery in 1991.
		Iijima is a microscopist at the NEC Corporation, a Japanese electronics company, and for many years he had studied the atomic-scale structure of carbon fibres.
		By passing electrical sparks between two closely spaced graphite rods, Iijima vaporized them and allowed the carbon to condense in a sooty mass.

		Iijima’s 1991 blockbuster from Nature (354:56, 1991), reporting the discovery of carbon nanotubes, falls just outside this survey’s 1992-2002 time frame, or the paper’s 3,300+ citations would have vaulted Iijima to the #2 spot among authors.

	Multiwall nanotubes: Nested cylinders or scrolls? (Site not responding. Last check: 2007-10-18)
		There appears to be no definitive agreement regarding the real topology of multi-wall nanotubes which have been discovered by Sumio Iijima, who was observing in a TEM the structure of the cathode of the carbon arc that had been used to produce fullerenes [1].
		The projected images can not easily be used to distinguish between nested, independent cylinders and a "scroll".
		The scroll model would provide a natural explanation of the fact that the inner diameter of multi-wall tubes is in most cases significantly larger than that of single-wall tubes.
