TL;DR: An isomerically pure sample of Gd(3)N@C(78) has been extracted from the carbon soot formed in the electric-arc generation of fullerenes using hollow graphite rods packed with Gd (2)O(3), under an atmosphere of helium and dinitrogen.
Abstract: An isomerically pure sample of Gd3N@C78 has been extracted from the carbon soot formed in the electric-arc generation of fullerenes using hollow graphite rods packed with Gd2O3 and graphite powder under an atmosphere of helium and dinitrogen. Purification has been achieved by chromatographic methods and the product has been characterized by mass spectrometry, UV/vis absorption spectroscopy, and cyclic voltammetry. Although a number of endohedral fullerenes have been found to utilize the D3h(5)-C78 cage, comparison of the spectroscopic and electrochemical properties of the previously characterized Sc3N@D3h(5)-C78 with those of Gd3N@C78 reveals significant differences that indicate that these two endohedrals do not possess the same cage structure. A single crystal X-ray diffraction study indicates that the fullerene cage does not follow the isolated pentagon rule (IPR) but has two equivalent sites where two pentagons abut. The endohedral has been identified as Gd3N@C2(22010)-C78. Two of the gadolinium atoms...

TL;DR: In this article, a number of composite-like samples of γ-cyclodextrin and HiPco carbon nanotubes were prepared using a simple grinding procedure, which has been reported to cut HiP co carbon nanitubes, and analyzed using absorption and Raman spectroscopy and differential scanning calorimetry.
Abstract: In this study a number of composite-like samples of γ-cyclodextrin and HiPco carbon nanotubes were prepared. The first sample was prepared by a simple grinding procedure, which has been reported to cut HiPco carbon nanotubes. The other samples were obtained via a refluxing procedure analogous to similar studies on other fullerenes and γ-cyclodextrin. The samples were analyzed using absorption and Raman spectroscopy, and differential scanning calorimetry. The results presented show clear evidence of an intermolecular interaction between γ-cyclodextrin and single-walled carbon nanotubes.

TL;DR: In this paper, a periodic $sp^2$-bonded carbon atomic planar sheet called octagraphene was constructed and its Young's modulus, breaking strength and Poisson's ratio were obtained.
Abstract: We study a versatile structurally favorable periodic $sp^2$-bonded carbon atomic planar sheet with $C_{4v}$ symmetry by means of the first-principles calculations. This carbon allotrope is composed of carbon octagons and squares with two bond lengths and is thus dubbed as octagraphene. It is a semimetal with the Fermi surface consisting of one hole and one electron pocket, whose low-energy physics can be well described by a tight-binding model of $\pi$-electrons. Its Young's modulus, breaking strength and Poisson's ratio are obtained to be 306 $N/m$, 34.4 $N/m$ and 0.13, respectively, which are close to those of graphene. The novel sawtooth and armchair carbon nanotubes as well as unconventional fullerenes can also be constructed from octagraphene. It is found that the Ti-absorbed octagraphene can be allowed for hydrogen storage with capacity around 7.76 wt%.

22 Aug 2006TL;DR: In this article, a bucky paper was used to represent a fullerene nanotube composition in the form of a felt, and the nanotubes may be derived with one or more functional groups.
Abstract: This invention relates generally to a fullerene nanotube composition. The fullerene nanotubes may be in the form of a felt, such as a bucky paper. Optionally, the fullerene nanotubes may be derivatized with one or more functional groups. Devices employing the fullerene nanotubes of this invention are also disclosed.
