Carbon Nanotubes--the Route Toward Applications
TLDR
Many potential applications have been proposed for carbon nanotubes, including conductive and high-strength composites; energy storage and energy conversion devices; sensors; field emission displays and radiation sources; hydrogen storage media; and nanometer-sized semiconductor devices, probes, and interconnects.Abstract:
Many potential applications have been proposed for carbon nanotubes, including conductive and high-strength composites; energy storage and energy conversion devices; sensors; field emission displays and radiation sources; hydrogen storage media; and nanometer-sized semiconductor devices, probes, and interconnects. Some of these applications are now realized in products. Others are demonstrated in early to advanced devices, and one, hydrogen storage, is clouded by controversy. Nanotube cost, polydispersity in nanotube type, and limitations in processing and assembly methods are important barriers for some applications of single-walled nanotubes.read more

Electron field emission from transparent multiwalled carbon nanotube sheets for inverted field emission displays
TL;DR: In this paper, Zhao et al. showed that strong, conducting, transparent carbon nanotube sheets were prepared by solid-state draw from well-ordered, aligned multi-walled carbon-nanotube (MWCNT) forests and showed threshold fields of less than 0.5 V/μm with current densities high enough for display applications.

Cobalt Porphyrin Functionalized Carbon Nanotubes for Oxygen Reduction
TL;DR: In this paper, a Co(II) porphyrin-based multi-walled carbon nanotubes (MWCNTs) were prepared by covalently grafting a Co((2)-PORPHyrin to functionalized MWCNTs via zwitterionic functionalization of the CNT sidewalls followed by a SN2 substitution reaction.

TL;DR: X-ray diffraction and electron microscopy showed that fullerene single-wall nanotubes (SWNTs) are nearly uniform in diameter and that they self-organize into “ropes,” which consist of 100 to 500 SWNTs in a two-dimensional triangular lattice with a lattice constant of 17 angstroms.

Nanobeam mechanics: Elasticity, strength, and toughness of nanorods and nanotubes
TL;DR: In this paper, the Young's modulus, strength, and toughness of nanostructures are evaluated using an atomic force microscopy (AFM) approach. And the results showed that the strength of the SiC NRs were substantially greater than those found previously for larger SiC structures, and they approach theoretical values.
