1991 New Scientist 16 Nov. 19/1 A Japanese scientist has discovered cylindrical carbon molecules, which he has dubbed ‘buckytubes’ because of their similarity to fullerenes, or ‘buckyballs’.
1992 New Scientist 29 Feb. 21/1 The molecules, known as buckytubes, are like sheets of graphite which have been rolled up into tubes about a micrometre long and up to 30 nanometres across.
1992 Sci. Amer. Oct. 92/3 Other buckytube variants should be insulators or semiconductors. But so far none has been shown to function as a superconductor.
1993 Science 9 Apr. 164/3 Buckyballs and buckytubes both form in an apparatus in which a carbon arc is enclosed in high-pressure helium gas.
