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.
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".
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.
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.
Katie Holmes understands the show must go on. The actress stopped by The Tonight Show Starring Jimmy Fallon Nov. 27 to discuss her role playing Mrs. Webb in the Broadway revival of Our Town ...
The most likely connection of fullerene units is [2+2] cycloaddition of two double bonds of the benzene parts of fullerene molecules. Cycloaddition provides a cyclobutane ring connecting two fullerene molecules. [12] [13] Photopolymerization of C60 Buckminsterfullerene forming cyclobutane bond via [2+2] cycloadition
