The fluorination of purified HiPco single-wall carbon nanotubes (SWNTs) to a stoichiometry CFx (x ≤ 0.2) followed by pyrolysis of the partially fluorinated SWNTs up to 1000 oC was found to have cut the nanotubes [...]
Of the myriad of potential application areas commonly associated with Nanotechnology, sensors and displays are two of the closest ones to commercial reality. The two materials systems that have given rise to high hopes in [...]
In this study, we focus on a comprehensive theoretical comparison between CNTs and BN-NTs, particularly for the radial breathing modes (RBMs), which are characteristic of nanotubes and do not have any corresponding modes in the [...]
A Monte Carlo simulation code has been developed aimed at finding a critical fractional volume of the nanotubes suspended in a low thermo-or electro-conductive medium. Over more than two orders of magnitude, the critical fractional [...]
The electronic structures of individual carbon nanotubes in a bundle are characterized by STM/STS technique. It is statistically found that the tubes with the same character tend to be assembled in one bundle and its [...]
As more experimental results become available and theoretical investigations get deeper, carbon nanotube (CNT) is found to be not as perfect as it seems. Due to this reason, the presence and roles of defects in [...]
We investigate the mechanical properties of SiC nanotubes using molecular dynamics simulation. We find that SiC nanotubes are less stiff than the other nanotubes considered so far, such as BN or C nanotubes. However, Youngs [...]

We gonna present our last developments over carbon nanotubes fibers. How we manage to go from lab process, to continuous process, and how we improve properties.
We study in detail the adsorption of Au on single walled carbon nanotubes (SWCN). All our results are based on ab initio total energy Density Functional Theory calculations using numerical orbitals as basis sets. We [...]
Because of the high reactivity of C-F bonds on the sidewalls of single-wall carbon nanotubes, fluorinated SWNTs (fluoronanotubes) can be used as precursors for further derivatization. One such reaction is to replace the fluorine with [...]
The complete set of 134 isolated-pentagon-rule (IPR) isomers of C94 has been studied by the SAM1, PM3, AM1, and MNDO quantum-chemical methods, MM3 force field method, ab initio HF/4-31G SCF calculation and density functional theory [...]
