The electrosynthesis, isolation and characterization of reaction products between [C.sub.60.sup.2-] and benzyl bromide in PhCN are reinvestigated. The visible and near-infrared spectra of the monoanion and dianion of 1,2-[(PhC[H.sub.2]).sub.2][C.sub.60] are described.

A Y-Ni alloy and graphite rod has been used to produce single-wall carbon nanotubes (SWCNTs) with 50%-70% purity. Experiments demonstrate that SWCNTs produced with yttrium-nickel as a catalyst have the same structures as those obtained with Co-Ni catalyst.

A stable mixed low-dimensional nanomaterial consisting of Mo[S.sub.2] inorganic nanoribbons encapsulated in carbon nanotubes (nanoburritos) is prepared and the method is also used for preparing nanoburritos composed of ultranarrow transition-metal chalcogenide nanoribbons and carbon nanotubes. The edges of the Mo[S.sub.2] nanoribbons are identified as zigzag-shaped by using both high-resolution transmission electron microscopy and density functional theory calculations.

The gate-controlled rectification behavior in [C.sub.70] at the rate single-walled carbon nanotube (SWNT) networks is reported at room temperature in air. The current rectification characteristics have resulted from highly asymmetric Schottky barriers between semiconducting peapods and the S/D electrodes.

The long fibers of high purity single-walled carbon nanotubes (SWNTs) are directly synthesized macroscopically by the modified arc discharge method. The purity of the SWNT in fibers are evaluated by scanning electron microscopy, thermogravimetric analysis, and Raman spectroscopy.

Study is conducted to demonstrate that iodine atoms/ions dope at the intratubular position in the [C.sub.60] peapods. It is found that the heating the iodine-doped peapod at 550 degree C induces the transformation of [C.sub.60] into a tubular structure.

Quasi-one-dimensional nanotubes and two-dimensional nanoribbons are two fundamental forms of nanostructures, and integrating them into a novel mixed low-dimensional nanomaterial is fascinating and challenging. We have synthesized a stable mixed low-dimensional nanomaterial consisting of MoS2 inorganic nanoribbons encapsulated in carbon nanotubes (which we call nanoburritos). This route can be extended to the synthesis of nanoburritos composed of other ultranarrow transition-metal chalcogenide nanoribbons and carbon nanotubes. The widths of previously synthesized MoS2 ribbons are greater than 50 nm, while the encapsulated MoS2 nanoribbons have uniform widths down to 1-4 nm and layer numbers down to 1-3, depending on the nanotube diameter. The edges of the MoS2 nanoribbons have been identified as zigzag-shaped using both high-resolution transmission electron microscopy and density functional theory calculations. [ABSTRACT FROM AUTHOR]

The article studies the coalescence of C60 molecules assisted by intratubular doped iodine atoms inside single-walled carbon nanotubes (SWNT). According to the results of the high-resolution transmission electron microscope and Raman spectroscopy, the doped iodine atoms can assist the structure transformation of fullerenes inside SWNTs. The authors note that heating the iodine-doped peopod at 550 °C induces the transformation of fullerenes into a tubular structure.
