Phonons in carbon nanotubes
A broad review of the unusual one-dimensional properties of phonons in carbon nanotubes is presented, including phonons in isolated nanotubes and in crystalline arrays of nanotubes in nanotubeExpand
Diameter-Selective Raman Scattering from Vibrational Modes in Carbon Nanotubes
Single wall carbon nanotubes (SWNTs) that are found as close-packed arrays in crystalline ropes have been studied by using Raman scattering techniques with laser excitation wavelengths in the rangeExpand
Raman scattering from high-frequency phonons in supported n-graphene layer films.
Results of room-temperature Raman scattering studies of ultrathin graphitic films supported on Si (100)/SiO2 substrates are reported. The results are significantly different from those known forExpand
Large-scale purification of single-wall carbon nanotubes: process, product, and characterization
We describe, in detail, a readily scalable purification process capable of handling single-wall carbon nanotube (SWNT) material in large batches. Characterization of the resulting material by SEM,Expand
Electromagnetic interference (EMI) shielding of single-walled carbon nanotube epoxy composites.
Single-walled carbon nanotube (SWNT)-polymer composites have been fabricated to evaluate the electromagnetic interference (EMI) shielding effectiveness (SE) of SWNTs. Our results indicate that SWNTsExpand
Debundling and dissolution of single-walled carbon nanotubes in amide solvents.
Wet chemical methods involving ultrasound and amide solvents were used to purify and separate large bundles of single-walled carbon nanotubes (SWNTs) into individual nanotubes that could then beExpand
Near-infrared emitting fluorophore-doped calcium phosphate nanoparticles for in vivo imaging of human breast cancer.
Early detection is a crucial element for the timely diagnosis and successful treatment of all human cancers but is limited by the sensitivity of current imaging methodologies. We have synthesized andExpand
Effect of the Growth Temperature on the Diameter Distribution and Chirality of Single-Wall Carbon Nanotubes
Pulsed laser vaporization of a heated, Fe/Ni or Co/Ni catalyzed, carbon target in argon gas has been used to synthesize single-wall carbon nanotubes (SWNTs). Electron microscopy, x-ray diffraction,Expand
Raman and IR spectroscopy of chemically processed single-walled carbon nanotubes.
IR and Raman spectroscopy has been used to study the evolution of the vibrational spectrum of bundled single-walled carbon nanotubes (SWNTs) during the purification process needed to remove metalExpand
Evidence for charge transfer in doped carbon nanotube bundles from Raman scattering
Single-walled carbon nanotubes (SWNTs) are predicted to be metallic for certain diameters and pitches of the twisted graphene ribbons that make up their walls. Chemical doping is expected toExpand
