Fibers of single wall carbon nanotubes extruded from super-acid suspensions exhibit preferred orientation along their axes. We characterize the alignment by x-ray fiber diagrams and polarized Raman scattering, using a model which allows for a completely unaligned fraction. This fraction ranges from 0.17 to 0.0560.02 for three fibers extruded under different conditions, with corresponding Gaussi...
This paper investigates the effective wall thickness of a single-walled carbon nanotube, a critical quantity for any research in mechanics and property characterization of carbon nanotubes. To this end, the response of a bundle of single-walled carbon nanotubes to external hydrostatic pressure was modeled using the ring theory of continuum mechanics. The model predicted that the equivalent thic...
The properties of a nanotube, such as the hydrophobicity and charge of the surface, can significantly affect water transport behavior. However, our knowledge of the effects of charge density, dipole orientation, frequency of flipping, and movement behavior on water flow through carbon nanotubes (CNTs) is far from adequate. This study is aimed at gaining insight into the transport of single-file...
Abstract A 3D self-supported integrated electrode, consisting of heteroatomic nitrogen-doped carbon nanotube arrays on cloth with confined ultrafine Co 4 N nanoparticles and a distribution anchored single-atom Co, is fabricated via cobalt-catalyzed growth strategy using dicyandiamide as the nitrogen source layered cobalt hydroxide-nitrate salt precursor. The abundance exposed active sites, name...
