Single-walled carbon nanotubes (SWCNTs) are a family of structurally related artificial nanomaterials with unusual properties and many potential applications. Most SWCNTs can emit spectrally narrow near-IR fluorescence at wavelengths that are characteristic of their precise diameter and chiral angle. Near-IR fluorimetry therefore offers a powerful approach for identifying the structural species...

Bilayer graphene nanoribbons (BGNRs) with a predefined width have been produced directly from bilayer graphene using a transmission electron microscope (TEM) in scanning mode operated at 300 kV. The BGNRs have been subsequently imaged in high-resolution TEM mode at 80 kV. During imaging, the interaction of the electrons with the sample induces structural transformations in the BGNR, such as clo...

Calcium carbonate (CaCO3) in the presence of single-walled carbon nanotube (SWCNT) /fullerodendron supramolecular nanocomposites was crystallized with a CO2 diffusion method under ambient conditions and in aqueous environments to produce monodisperse spherical SWCNT/CaCO3 hybrids with a core-shell structure. The crystals nucleate at the carboxyl groups on the surface of the SWCNT/fullerodendron...

Chemical detection is still a continuous challenge when it comes to designing single-walled carbon nanotube (SWCNT) sensors with high selectivity, especially in complex chemical environments. A perfect example of such an environment would be in thermally oxidized soybean oil. At elevated temperatures, oil oxidizes through a series of chemical reactions which results in the formation of monoacyl...

We report for the first time on finding shortest path solutions for the travelling salesman problem (TSP) using hybrid “in materio” computation: a technique that uses search algorithms to configure materials for computation. A single-walled carbon nanotube (SWCNT) / polymer composite material deposited on a micro-electrode array is configured using static voltages so that voltage output reading...

We present a theoretical study of the spin transport through a manganese phthalocyanine (MnPc) molecule sandwiched between two semi-infinite armchair single-walled carbon nanotube (SWCNT) electrodes. Ab initio modeling is performed by combing the nonequilibrium Green's function formalism with spin density functional theory. Our calculations show that MnPc not only can act as a nearly perfect sp...

Atomistic simulation of defect-free single-walled carbon nanotube (SWCNT) growth is essential for the insightful understanding of the SWCNT's growth mechanism. Despite the extensive effort paid in the past two decades, the goal has not been completely achieved, due to the huge timescale discrepancy between atomistic simulation and the experimental synthesis of SWCNTs, as well as the lack of an ...

Based on plasma-treated single wall carbon nanotubes (SWCNTs), SWCNT/SiO(2) and thiol groups-functionalized SWCNT/SiO(2) hybrids have been fabricated through a sol-gel process. By means of thiol groups, Ag nanoparticles have been in situ synthesized and bonded onto the SiO(2) shell of SWCNT/SiO(2) in the absence of external reducing agent, resulting in the stable carbon nanotube/SiO(2)/Ag nanop...

Carbon vacuum arc was used to deposit 5–25 nm thick carbon coatings on single-walled carbon nanotube (SWCNT) networks. The SWCNT bundles thus embedded in conformal coatings maintained their optical transparency and electrical conductivity. Sheet resistances of the networks were measured during the vacuum arc deposition, revealing initially a 100-fold increase, followed by significant recovery a...

Carbon nanotubes with their outstanding mechanical, physical and electrical properties have stimulated a significant amount of scientific technological research due to uniqueness compared conventional materials. As result, an extensive study on mechanical has been conducted, the static dynamic behavior single- walled multi-walled carbon examined using Euler-Bernoulli Timoshenko beam models. The...
