Pressure-induced transition in magnetoresistance of single-walled carbon nanotubes.

Functionalization of the Single-walled Carbon Nanotubes by Sulfur Dioxide and Electric Field Effect, a Theoretical Study on the Mechanism

In this study, kinetics and mechanism of the sulfur dioxide adsorption on the single-walled carbon nanotubes (CNT) are investigated. Three single-walled carbon nanotubes, including the armchair (6,6), chiral (6,5) and zigzag (6,0) CNTs were chosen as the models and the different orientations of SO2 molecule relative to the CNT axis were considered. The B3LYP functional within the 6-3...

Spin-polarized transport in carbon nanotubes

We present transport measurements of ferromagnetically contacted carbon nanotubes. In both singleand multi-walled nanotube devices, a spin valve effect is observed due to spin-polarized transport. In one single-walled nanotube device, the spin-valve effect is suppressed as the influence of Coulomb charging is observed at around 10 K. To help understand the interplay between the Coulomb charging...

Theoretical Study of Addition Reaction of Carbene and Zigzag Single-walled Carbon Nanotube

The reaction mechanism between (H2C) and (7, 0), zigzag single-walled carbon nanotubes(ZSWCNTs) on two different orientation of C-C have been studied by semi empirical AM!method. The activation barriers of (H2C) adding to (7, 0) ZSWCNT are computed and compared.The effects of diameters of zigzag SWCNT on their binding energies were studied

Shape transition of unstrained flattest single-walled carbon nanotubes under pressure

Radius Dependence of Hydrogen Storage Inside Single Walled Carbon Nanotubes in an Array

In this study, we have investigated radius dependence of hydrogen storage within armchair (n,n) single walled carbon nanotubes (SWCNT) in a square arrays. To this aim, we have employed equilibrium molecular dynamics (MD) simulation. Our simulations results reveal that radius of carbon nanotubes are an important and influent factor in hydrogen distribution inside carbon nanotubes and consequentl...
