Sumio Iijima (飯島 澄男, Iijima Sumio, born 2 May 1939) is a Japanese physicist and inventor, often cited as the inventor of carbon nanotubes.Although carbon nanotubes had been observed prior to his "invention", Iijima's 1991 paper generated unprecedented interest in the carbon nanostructures and has since fueled intense research in the area of nanotechnology.
Nanotubes synthesized hollow carbon molecules and determined their crystal structure for the first time in the soot of arc discharge at NEC, by Japanese researcher Sumio Iijima. [ 13 ] August — Nanotubes discovered in CVD by Al Harrington and Tom Maganas of Maganas Industries, leading to development of a method to synthesize monomolecular ...
Carbon nanobuds are a newly created material combining two previously discovered allotropes of carbon: carbon nanotubes and fullerenes. In this new material, fullerene-like "buds" are covalently bonded to the outer sidewalls of the underlying carbon nanotube.
Smalley's latest research was focused on carbon nanotubes, specifically focusing on the chemical synthesis side of nanotube research. He is well known for his group's invention of the high-pressure carbon monoxide (HiPco) method of producing large batches of high-quality nanotubes. [ 24 ]
He demonstrated carbon fibers can be grown by gas pyrolysis and traveled to Orléans, France in 1974 working with Madame Agnès Oberlin at CNRS in her laboratory. He discovered carbon nanotubes in 1976 [1] as part of his studies at University of Orleans in France. He has been awarded the Charles E. Pettinos Award from the American Carbon ...
Iijima's discovery of multi-walled carbon nanotubes in the insoluble material of arc-burned graphite rods in 1991 [31] and Mintmire, Dunlap, and White's independent prediction that if single-walled carbon nanotubes could be made, then they would exhibit remarkable conducting properties [32] helped create the initial buzz that is now associated ...
A nanotube is a nanoscale cylindrical structure with a hollow core, typically composed of carbon atoms, though other materials can also form nanotubes. Carbon nanotubes (CNTs) are the most well-known and widely studied type, consisting of rolled-up sheets of graphene with diameters ranging from about 1 to tens of nanometers and lengths up to ...
1993: groups led by Donald S. Bethune at IBM and Sumio Iijima at NEC independently discovered single-wall carbon nanotubes and methods to produce them using transition-metal catalysts. 1994: The local average treatment effect (LATE) was first introduced in the econometrics literature in 1994 by Guido W. Imbens and Joshua D. Angrist , [ 125 ...
