Single walled carbon nanotube shows excellent chemical and physical properties and it has been extensively explored for novel applications. It has been shown that single walled carbon nanotube can be used to improve sensitivity of sensors such as bio sensors, gas sensors and mechanicals sensor by its unique properties. As a mechanical sensor, a mechanical force deforms the single walled carbon ...

Single-walled carbon nanotubes (SWCNTs) are hollow, long cylinders with extremely large aspect ratios, made of one atomic sheet of carbon atoms in a honeycomb lattice. They possess extraordinary thermal, mechanical, and electrical properties and are considered as one of the most promising nanomaterials for applications and basic research. This chapter describes the structural, electronic, vibra...

The synthesis of carbon nanotubes (CNTs) of desired chiralities and diameters is one of the most important challenges in nanotube science and achieving such selectivity may require a detailed understanding of their growth mechanism. We report the formation of CNTs in an entirely condensed phase process that allows us, for the first time, to monitor the nucleation of a nanotube on the spherical ...

Carbon nanotube adhesion force measurements were performed on single-walled nanotubes grown over lithographically defined trenches. An applied vertical force from an atomic force microscope (AFM), in force distance mode, caused the tubes to slip across the 250-nm-wide silicon dioxide trench tops at an axial tension of 8 nN. The nanotubes slipped at an axial tension of 10 nN after being selectiv...

We performed ab initio calculations of the anisotropic dielectric response of small-diameter single-walled carbon nanotubes in the framework of time-dependent density-functional theory. The calculated optical spectra are in very good agreement with experiment, both concerning absolute peak positions and anisotropy effects. The latter can only be described correctly when crystal local-field effe...

Abstract The synthesis of ultrathin rhenium disulfide (ReS 2 ) nanoribbons within single-walled carbon nanotubes (SWNTs) has been established. Dirhenium decacarbonyl complex is encapsulated into the SWNTs to provide a source confined atoms, which readily react with iodine form discrete nm-sized clusters iodide [Re 6 I 14 ] 2− embedded in nanotubes. final step accomplished by admitting hydrogen ...

Carbon nanotubes display either metallic or semiconducting properties. Both large, multiwalled nanotubes (MWNTs), with many concentric carbon shells, and bundles or "ropes" of aligned single-walled nanotubes (SWNTs), are complex composite conductors that incorporate many weakly coupled nanotubes that each have a different electronic structure. Here we demonstrate a simple and reliable method fo...

We have measured the Raman spectrum of individual single walled carbon nanotubes in solution and compare it to that obtained from the same starting material where the tubes are present in ordered bundles or ropes. Interestingly, the radial mode frequencies for the tubes in solution are found to be approximately 10 cm (-1) higher than those observed for tubes in a rope, in apparent contradiction...

Polyiodide species were synthesized by the acceleration of an acidic environment in nanospace single-walled carbon nanotubes (SWCNT) with light irradiation. Raman and EXAFS results strongly support production polyiodide after adsorption CsI on SWCNT from aqueous solution. Interestingly, reaction was initiated nano-confined phase formed a basic environment. The plays essential role as oxidant fo...
