Cutting, Solubilizing and Size-Sorting of Single-Wall Carbon Nanotubes
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 [...]
Nanotubes and Nanoribbons in Displays, NEMS, and Chemical Sensors: Recent results from First-Principles Quantum Mechanics simulations
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 [...]
A Comparative Theoretical Study of Carbon and Boron-Nitride Single-wall Nanotubes
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 [...]
Monte Carlo Simulations of Nanotube Suspensions and Composites
Foygel M., Morris R.D., Anez D., French S., Sobolev V., South Dakota School of Mines and Technology, US
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 [...]
STM/STS Studies of SWNTs in Bundles, C60 Thin Films and DNA Molecules
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 [...]
Mechanical Properties of SiC Nanotubes
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 [...]
Carbon Nanotube Nano-Composite Fibers and Carbon Nanotube Fibers by Wet Spinning Process
Poulin P., Vigolo B., Bernier P., Paillet M., Launois P., Soutric F., Dieudonne M., Grac M., Gedda K., Nanoledge, FR
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.
Adsorption of Gold Atoms on Carbon Nanotubes
da Silva A.J.R., da Silva E.Z., Carrijo Faria J., da Silva A.J.R., da Silva E.Z., Fazzio A., Universidade de Sao Paulo, BR
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 [...]
Sidewall Functionalization of Single-Walled Carbon Nanotubes through C-N Bond Forming Substitution Reactions of Fluoronanotubes
Stevens J., Kini V.U., Huang A., Chiang I.W., Derrien G.A., Khabashesku V.N., Margrave J.L., Rice University, US
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 [...]
Computing Enthalpy-Entropy Interplay for Isomeric Fullerenes: C94 IPR Set
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 [...]
