In this communication, we report the preparation of DNA-SWNT hybrid hydrogel which is pH responsive and strength tunable.

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...

The nanotribological characterization of carbon nanotubes is fundamental for the exploration of new sliding applications. In this study, a comprehensive investigation of adhesion, friction and wear of a multiwalled nanotube (MWNT) tip, and SWNT (single-walled nanotube) and MWNT arrays has been carried out. A nonlinear response of the MWNT tip is observed when the tip is brought into and out of ...

A pigment array has been constructed within a paracrystalline amyloid nanotube and Förster energy transfer along the nanotube surface has been demonstrated to self-assembled acceptor dyes.

Electrical sensitivity of a boron nitride nanotube (BNNT)  was examined toward C2H5OH molecules by using density functional theory (DFT)  calculations . It was founding that the adsorption energy(Ead) of ethanol on the  pristine  nanotubes  is about -51.5 kJ / mol, but when  the nanotube has been doped  with Si and Al atoms , the adsorption  and recovery time ch...

in this paper, we have used density functional perturbation theory (dfpt) and pseudo-potential method to calculate the phonon spectrum, phonon density of states (dos), specific heat capacity and mechanical properties of (5,5) armchair and (9,0) zigzag single wall carbon nanotubes (swcnts). our calculations show that young’s modulusfor (5,5) and (9,0) nanotubesare higher than 1tpa. we have also ...

We show that the number of concentric graphene cylinders forming a carbon nanotube can be found by squeezing the tube between an atomic force microscope tip and a silicon substrate. The compressed height of a single-walled nanotube (double-walled nanotube) is approximately two (four) times the interlayer spacing of graphite. Measured compression forces are consistent with the predicted bending ...
