  2. Fullerene - Wikipedia

    en.wikipedia.org/wiki/Fullerene

    There are two major families of fullerenes, with fairly distinct properties and applications: the closed buckyballs and the open-ended cylindrical carbon nanotubes. [27] However, hybrid structures exist between those two classes, such as carbon nanobuds — nanotubes capped by hemispherical meshes or larger "buckybuds".

    Non-IPR fullerenes have thus far only been isolated as endohedral fullerenes such as Tb 3 N@C 84 with two fused pentagons at the apex of an egg-shaped cage. [4] or as fullerenes with exohedral stabilization such as C 50 Cl 10 [5] and reportedly C 60 H 8. [6] Fullerenes with fewer than 60 carbons do not obey isolated pentagon rule (IPR).

  4. Allotropes of carbon - Wikipedia

    en.wikipedia.org/wiki/Allotropes_of_carbon

    Carbon nanotubes, also called buckytubes, are cylindrical carbon molecules with novel properties that make them potentially useful in a wide variety of applications (e.g., nano-electronics, optics, materials applications, etc.). They exhibit extraordinary strength, unique electrical properties, and are efficient conductors of heat.

  5. C70 fullerene - Wikipedia

    en.wikipedia.org/wiki/C70_fullerene

    C 70 fullerene is the fullerene molecule consisting of 70 carbon atoms. It is a cage-like fused-ring structure which resembles a rugby ball, made of 25 hexagons and 12 pentagons, with a carbon atom at the vertices of each polygon and a bond along each polygon edge.

  6. Polyfullerene - Wikipedia

    They can be synthesized by incorporating fullerenes onto the ends of polymerized chains or growth of a polymeric chain from a functionalized fullerene derivative and additionally closure. Introducing fullerene spheres into the end of the macromolecule significantly increases hydrophobicity of the original polymer.

  7. Sphere packing in a cylinder - Wikipedia

    It is used to describe arrangements of leaves of a plant, pine cones, or pineapples, but also planar patterns of florets in a sunflower head. While the arrangement in the former are cylindrical, the spirals in the latter are arranged on a disk. For columnar structures phyllotaxis in the context of cylindrical structures is adopted.

  9. Buckminsterfullerene - Wikipedia

    en.wikipedia.org/wiki/Buckminsterfullerene

    These endohedral fullerenes are usually synthesized by doping in the metal atoms in an arc reactor or by laser evaporation. These methods gives low yields of endohedral fullerenes, and a better method involves the opening of the cage, packing in the atoms or molecules, and closing the opening using certain organic reactions. This method ...
