TL;DR: In this article, the fluorination of C{sub 60} and mixtures of C {sub 60/C{sub 70} in a F{sub 2}/He atmosphere using different temperature regions was discussed.
Abstract: This report discusses the fluorination of C{sub 60} and mixtures of C{sub 60}/C{sub 70} in a F{sub 2}/He atmosphere using different temperature regions. The resulting fluorinated fullerenes were studied by a variety of mass spectrometry methods using positive and negative ion mass analysis. Infrared and ultraviolet-vis spectroscopy were recorded for these samples as well. 22 refs., 5 figs.

TL;DR: In this paper, the chemistry, energy, and spatial distribution of species in carbon-nitrogen plasma plumes were investigated to define plasma conditions for growth of carbon nitride CNx films with a fullerene-like structure.
Abstract: Chemistry, energy, and spatial distributions of species in carbon–nitrogen plasma plumes were investigated to define plasma conditions for growth of carbon nitride CNx films with a fullerene-like structure. Plumes were generated by ablation of graphite using a 248 nm excimer laser in the presence of low-pressure nitrogen. The plumes were investigated using element specific imaging, time-of-flight experiments, fluorescence spectroscopy, and molecular vibration sequence analyses. Studies showed the importance of plume/substrate interaction in causing secondary excitation phenomena. For N2 pressures within the 5–50 mTorr range, plasmas at the substrate vicinity were found to consist mostly of atomic carbon, CN and C2 molecules. Kinetic energies were calculated within 10–20 eV for mono atomic carbon, 30–55 eV for CN, and 20–40 eV for C2. Excited CN and C2 molecules were generated by laser ablation and by collisions of the plume with the substrate surface. Their vibrational energies were strongly influenced by...

TL;DR: It can be seen that the solubility of functionalized carbon nanotubes is higher than functionalized fullerenes, and both dissolutions in water are thermodynamically favorable.

TL;DR: In this article, double-wall carbon nanotubes with natural carbon outer and highly enriched inner walls were synthesized from isotope enriched fullerenes encapsulated in single-wall Carbon Nanotubes (SWCNTs).
Abstract: The synthesis of a unique isotope engineered system, double-wall carbon nanotubes with natural carbon outer and highly $^{13}\mathrm{C}$ enriched inner walls, is reported from isotope enriched fullerenes encapsulated in single-wall carbon nanotubes (SWCNTs). The material allows the observation of the $D$ line of the highly defect-free inner tubes that can be related to a curvature induced enhancement of the electron-phonon coupling. Ab initio calculations explain the inhomogeneous broadening of inner tube Raman modes due to the distribution of different isotopes. Nuclear magnetic resonance shows a significant contrast of the isotope enriched inner SWCNTs compared to other carbon phases and provides a macroscopic measure of the inner tube mass content. The high curvature of the small diameter inner tubes manifests in an increased distribution of the chemical shift tensor components.
