Carbon nanotubes are promising nanoscale materials for novel electrical, mechanical, chemical, and biological device and sensors based on its outstanding properties. Single walled carbon nanotubes can be either semiconducting or metallic material depending on its structures. However, controlling the structure is quite challenging with current technologies. For the network formation of the singl...

Aligned single-walled carbon nanotube arrays provide a great potential for the carbon-based nanodevices and circuit integration. Aligning single-walled carbon nanotubes with selected helicities and identifying their helical structures remain a daunting issue. The widely used gas-directed and surface-directed growth modes generally suffer the drawbacks of mixed and unknown helicities of the alig...

Controlling the covalent bonding of antibodies onto functionalized carbon nanotubes is a key step in the design and preparation of nanotube-based conjugates for targeting cancer cells. For this purpose, an anti-MUC1 antibody (Ab) is linked to both multi-walled (MWCNTs) and double-walled carbon nanotubes (DWCNTs) using different synthetic strategies. The presence of the Ab attached to the nanotu...

In this work, the structural and electronic properties of folic acid molecule on functionalized (7,0)zigzag single-walled carbon nanotube was studied in gas phase on the basis of density functionaltheory (DFT). Furthermore, covalent interaction of folic acid with single-walled carbon nanotube wasinvestigated and its quantum molecular descriptors and binding energies were calculated. The DFTB3LY...

This paper developed an effective multiscale method for analysing the deformation of NanoElectroMechanical (NEM) switches based on carbon nanotubes. The switches were simplified to beam systems with loads calculated from three-coupled energy domains: the electrostatic energy domain, the elastostatic energy domain, and the van der Waals energy domain. A meshless formulation was then used to disc...

We studied the spectral diffusion and exciton fine structures of single-walled carbon nanotubes (SWNTs) using single carbon nanotube spectroscopy. Two types of single nanotube photoluminescence (PL) spectra were observed at temperatures below 50 K, double peaks with spectral diffusion and a single peak without spectral diffusion. The spectral diffusion occurring in the lower energy peak of the ...

Carbon nanotube (CNT) membranes allow the mimicking of natural ion channels for applications in drug delivery and chemical separation. Double-walled carbon nanotube membranes were simply functionalized with dye in a single step instead of the previous two-step functionalization. Non-faradic electrochemical impedance spectra indicated that the functionalized gatekeeper by single-step modificatio...

We present atomic-scale, video-rate environmental transmission electron microscopy and in situ time-resolved X-ray photoelectron spectroscopy of surface-bound catalytic chemical vapor deposition of single-walled carbon nanotubes and nanofibers. We observe that transition metal catalyst nanoparticles on SiOx support show crystalline lattice fringe contrast and high deformability before and durin...
