Selective bundling of zigzag single-walled carbon nanotubes.
A simple, high throughput fractionation procedure for aqueous/SDS (sodium dodecyl sulfate) suspensions of single-walled carbon nanotubes (SWNTs) is presented, which yields thin bundles of semiconducting-SWNTs with small chiral angles. To demonstrate this we show the photoluminescence signatures of nanotube suspensions that contain almost exclusively zigzag and near-zigzag tubes. Starting suspen...
متن کاملBundling dynamics of single walled carbon nanotubes in aqueous suspensions
A simple optical method based on absorption of monochromatic light to investigate the dynamics of single walled carbon nanotube SWCNT suspensions is described. The well dispersed suspensions display a complex behavior, exhibiting peaks due to resonant scattering from SWCNT bundles with increasing diameters as a function of time. The results indicate that the bundling of SWCNTs initiates almost ...
متن کاملBuckling of nanotubes under compression considering surface effects
In this paper, the modified Euler-Bernoulli beam model is presented to examine the influence of surface elasticity and residual surface tension on the critical force of axial buckling of nanotubes in the presence of rotary inertia. An explicit solution is derived for the buckling loads of microscaled Euler beams considering surface effects. The size-dependent buckling behavior of the nanotube d...

متن کاملTransport Properties For Carbon Nanotubes Under Hydrostatic Pressure
Multi-wall carbon nanotubes (MWNTs) were mixed with polystyrene (PS) by 20 wt%, which is slightly above the percolation threshold. Temperature (T ) dependencies of Seebeck coefficient (S) and resistance (R) for the sample (MWNT-PS) were measured under hydrostatic pressure upto 1.2 GPa. The resistance at ambient pressure showed power law T -dependence (R ∝ T−α) and agreed well with Luttinger liq...
