F.V. Ferreira,Felipe Sales Brito,Wesley Franceschi,Evelyn Alves Nunes Simonetti,Luciana De Simone Cividanes,Mircea Chipara,Karen Lozano +6 more
TL;DR: In this paper, the effects of amine-modified graphene oxide on dispersion and micro-hardness of epoxy based nanocomposites are reported, where the modified Hummers method was used followed by hexamethylenediamine functionalization.
Journal ArticleDOI
Microwave Makes Carbon Nanotubes Less Defective
TL;DR: Fibers spun from the as-annealed CNTs show increases of approximately 35% and approximately 65%, respectively, in tensile strength and modulus during tensile testing; an approximately 20% improvement in electrical conductivity was also reported.
Journal ArticleDOI
Decoration of gold nanoparticles on surface-grown single-walled carbon nanotubes for detection of every nanotube by surface-enhanced Raman spectroscopy.
TL;DR: Investigations over the effect of the laser wavelength and the interparticle distance on the SERS enhancement factors of SWCNTs prove that the coupled surface plasmon resonance absorption of the high-density gold nanoparticles decorated on SWC NTs contributes most to the strong surface enhancement.

Raman Spectrum of Graphite
F. Tuinstra,J. L. Koenig +1 more
TL;DR: Raman spectra are reported from single crystals of graphite and other graphite materials as mentioned in this paper, and the Raman intensity of this band is inversely proportional to the crystallite size and is caused by a breakdown of the k-selection rule.

TL;DR: At pH less than 5, the absorption and emission spectra of individual nanotubes show evidence of band gap–selective protonation of the side walls of the tube, which is readily reversed by treatment with base or ultraviolet light.

Unusually High Thermal Conductivity of Carbon Nanotubes
TL;DR: An unusually high value, lambda approximately 6600 W/m K, is suggested for an isolated (10,10) nanotube at room temperature, comparable to the thermal conductivity of a hypothetical isolated graphene monolayer or diamond.
