Classification for double-walled carbon nanotubes

Carbon, 1999
A classification method for double-walled carbon nanotubes is proposed taking account of the geometric constraints. The different possibilities of interlayer interactions are examined.

Ferromagnetism of double-walled carbon nanotubes

Applied Physics Letters, 2010
The pure double-walled carbon nanotubes (DWNTs) and two endohedral DWNTs (DWNTs with materials filled inside) are produced. The filling materials are CoI2 and KI, respectively. The ferromagnetism (FM) is observed in pure DWNTs. The content of residual catalyst Fe is too small to be responsible for the observed FM. On the other hand, after filling KI or

Connection of macro-sized double-walled carbon nanotube strands by bandaging with double-walled carbon nanotube films

Carbon, 2007
Based on their special shrinkage characteristics, double-walled carbon nanotube (DWCNT) films were used as bandages to bind the overlapped ends of macro-sized (centimeters long) DWCNT strands for connection to get structures of random length. Tensile tests indicated that the joints made in this way had relatively high tensile strength with a maximum ...

Microwave-Assisted Bromination of Double-Walled Carbon Nanotubes

Chemistry of Materials, 2009
The synthesis and characterization of double-walled carbon nanotubes (DWCNT) functionalized with Br (Br-DWCN) under microwave assisted (MiW) conditions, to link covalently the Br atoms to DWCNT with a percentage of functionalization of carbon 5-8 % in weight has been demonstrated. 30 mg of DWCNT were mixed with 5 ml of an aqueous solution of Br in a 10

Tube–tube interaction in double‐wall carbon nanotubes

physica status solidi (b), 2006
AbstractIn a Raman map of double‐wall carbon nanotubes, the radial breathing modes of the inner tubes are grouped into clusters with similar resonance behavior. These clusters are located close to the resonances of SDS wrapped HiPco tubes and can spread over 30 cm–1. Compared to the HiPco tubes the resonances of the inner tubes are shifted about 50 meV

Coaxial nanocables of codoped double-walled carbon nanotubes

The Journal of Chemical Physics, 2009
The electronic and optical properties of codoped double-walled carbon nanotubes (DWNTs), in which nucleophilic atoms (potassium) are adsorbed outside the outer tube and electrophilic molecules (NO2) are adsorbed inside the inner tube, are investigated by density functional theory. It is found that the inner core tube is p-type doped and the outer shell

Tailoring double-wall carbon nanotubes?

AIP Conference Proceedings, 2003
Double‐wall carbon nanotubes (DWNTs) are interesting nano‐objects derived from single‐wall nanotubes (SWNTs) whose potentiality for some applications (such as composite reinforcement) are even more promising than for SWNTs. Depending on the respective chirality of the inner and outer SWNTs involved, electronic properties may also vary, with subsequent ...

Investigation of the Pulmonary Bioactivity of Double-Walled Carbon Nanotubes

Journal of Toxicology and Environmental Health, Part A, 2013
Double-walled carbon nanotubes (DWCNT) are a rather new and unexplored variety of carbon nanotubes. Previously conducted studies established that exposure to a variety of carbon nanotubes produced lung inflammation and fibrosis in mice after pharyngeal aspiration.

Raman scattering from double‐walled carbon nanotubes

Journal of Raman Spectroscopy, 2007
AbstractRaman scattering from double‐walled carbon nanotubes is reported with particular emphasis on the response from the radial breathing mode (RBM) of the inner‐shell tubes. The unexpected large number of very narrow lines observed is explained by the growth of one and the same inner tube type in different outer tubes in a highly shielded ...
