We present a simple and scalable fluidic-assembly approach, in which bundles of single-walled carbon nanotubes (SWCNTs) are selectively aligned and deposited by directionally controlled dip-coating and solvent evaporation processes. The patterned surface with alternating regions of hydrophobic polydimethyl siloxane (PDMS) (height ~ 100 nm) strips and hydrophilic SiO2 substrate was withdrawn ver...
We introduce a simple approach to fabricate an aligned carbon nanotube (ACNT) device for broadband polarization control in fiber laser systems. The ACNT device was fabricated by pulling from as-fabricated vertically-aligned carbon nanotube arrays. Their anisotropic properties are confirmed with various microscopy techniques. The device was then integrated into fiber laser systems (at two techno...
Using reflection high-energy electron diffraction, we have observed diffraction patterns from both vertically aligned and randomly oriented multiwalled carbon nanotube samples. The patterns, for both samples, consist of rings and are similar to the patterns observed in x-ray diffraction from multiwalled carbon nanotubes. The ring radii are roughly consistent with powder diffraction from graphit...
This paper discuss about the critical review on design of carbon nanotube based MEMS piezoresistive pressure sensors, use of different types of carbon nanotubes such as multi-walled carbon nanotubes (MWCNTs), single-walled carbon nanotubes (SWNTs) and vertically aligned carbon nanotubes (VANTs), sensing mechanism, applications, etc. The structural deformation of the piezoresistive nano structur...
The adhesion of cells to vertically aligned TiO2 nanotubes is reviewed. The attraction between a negatively charged nanotube surface and a negatively charged osteoblast is facilitated by charged protein-mediators like proteins with a quadrupolar internal charge distribution, fibronectin and vitronectin. It is shown that adhesion and spreading of osteoblasts on vertically aligned TiO2 nanotube s...
An all-fiber passive laser mode locking is realized with a vertically aligned single-walled carbon nanotube film that can be transferred onto an arbitrary substrate using only hot water. A D-shaped fiber is employed as the substrate for the evanescent field interaction of propagating light with the nanotubes. The scheme highlights the efficient interaction achieved by the nanotube alignment as ...
