  2. Fullerene chemistry - Wikipedia

    en.wikipedia.org/wiki/Fullerene_chemistry

    Fullerene or C 60 is soccer-ball-shaped or I h with 12 pentagons and 20 hexagons. According to Euler's theorem these 12 pentagons are required for closure of the carbon network consisting of n hexagons and C 60 is the first stable fullerene because it is the smallest possible to obey this rule.

  3. Fullerene - Wikipedia

    en.wikipedia.org/wiki/Fullerene

    Fullerenes had been predicted for some time, but only after their accidental synthesis in 1985 were they detected in nature [3] [4] and outer space. [5] [6] The discovery of fullerenes greatly expanded the number of known allotropes of carbon, which had previously been limited to graphite, diamond, and amorphous carbon such as soot and charcoal.

  4. Potential applications of carbon nanotubes - Wikipedia

    en.wikipedia.org/wiki/Potential_applications_of...

    The use in tensile stress or toxic gas sensors was proposed by Tsagarakis. [170] A flywheel made of carbon nanotubes could be spun at extremely high velocity on a floating magnetic axis in a vacuum, and potentially store energy at a density approaching that of conventional fossil fuels.

  5. Noble gas compound - Wikipedia

    en.wikipedia.org/wiki/Noble_gas_compound

    Structure of a noble-gas atom caged within a buckminsterfullerene (C 60) molecule. Noble gases can also form endohedral fullerene compounds where the noble gas atom is trapped inside a fullerene molecule. In 1993, it was discovered that when C 60 is exposed to a pressure of around 3 bar of He or Ne, the complexes He@C 60 and Ne@C 60 are formed ...

  6. Fullerene whiskers - Wikipedia

    en.wikipedia.org/wiki/Fullerene_whiskers

    Fullerene whiskers and tubes are held together by weak van der Waals forces, and hence are very soft. [1] They can be grown by precipitation at an interface between two liquids. They are semiconductors and have potential uses in field-effect transistors , solar cells , chemical sensors, and photocatalysts .

  7. Synthesis of carbon nanotubes - Wikipedia

    en.wikipedia.org/wiki/Synthesis_of_carbon_nanotubes

    The substrate is heated to approximately 700 °C. To initiate the growth of nanotubes, two gases are bled into the reactor: a process gas (such as ammonia, nitrogen or hydrogen) and a carbon-containing gas (such as acetylene, ethylene, ethanol or methane). Nanotubes grow at the sites of the metal catalyst; the carbon-containing gas is broken ...

  8. Polyfullerene - Wikipedia

    en.wikipedia.org/wiki/Polyfullerene

    Fullerene is a relatively new substance in chemistry sciences. Buckminsterfullerene itself was discovered in 1985 [1] and the first fullerene-containing polymers were reported at least 6 [2] years later. The main milestones in the use of fullerene in polymer chemistry are listed below: 1992 – Synthesis of organometallic C 60 polymer (C 60 Pd ...

  9. Endohedral fullerene - Wikipedia

    en.wikipedia.org/wiki/Endohedral_fullerene

    Alternatively, endohedral hydrogen fullerenes can be produced by opening and closing a fullerene by organic chemistry methods. A recent example of endohedral fullerenes includes single molecules of water encapsulated in C 60. [10] Noble gas endofullerenes are predicted to exhibit unusual polarizability.
