When using single-walled carbon nanotube (SWNT) probes to create AFM images of SWNT samples in tapping mode, elastic deformations of the probe and sample result in a decrease in the apparent width of the sample. Here we show that there are two major mechanisms for this effect, smooth gliding and snapping, and compare their dynamics to the case when a conventional silicon tip is used to image a ...

Density functional theory is employed to study Pd and Pd/Ni alloy monatomic axial and circular chain-functionalized metallic single walled carbon nanotube SWNT(6,6) and semi-conducting SWNT(10,0), and their interactions with hydrogen molecules. The stable geometries and binding energies have been determined for both isolated chains and chains on SWNT surface. We found that both axial and radial...

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

Temperature programmed oxidation (TPO) coupled with in situ Raman spectroscopy has been used as an effective qualitative and quantitative analysis of raw and purified single-walled carbon nanotubes (SWNT) samples. The incorporation of Raman facilitates the identification of the nature of the oxidation peaks present in a TPO profile. Using different samples it was possible to evaluate the potent...

Smooth and aligned single walled carbon nanotube (SWNT) thin films with improved optoelectronic performance are fabricated using a superacid slide casting method. Deposition of as made SWNT thin film on silicon (Si) together with post treatments result in SWNT/Si hybrid solar cells with unprecedented high fill factor of 73.8%, low ideality factor of 1.08 as well as overall dry cell power conver...

Many potential biological applications of single-walled carbon nanotubes (SWNTs) require their dispersion in aqueous conditions. Recently, Dieckmann et al. designed a series of reversible cyclic peptides (RCPs) which exist in linear or cyclized states through controlled formation of an intramolecular disulfide bond between terminal Cys residues. These RCP-Cys peptides have been shown to dispers...

The structural and mechanical properties of single-walled carbon nanotubes (SWNTs) make them ideal tips for scanning probe microscopies such as atomic force microscopy (AFM). However, the ideal nanotube probe, which corresponds to an individual SWNT, has been difficult to produce in high yield. To overcome this difficulty, a straightforward and easily implemented method that enables very high-y...

Abstract Thermal boundary resistance (TBR) between a single-walled carbon nanotube (SWNT) and matrices of solid and liquid argon was investigated by performing classical molecular dynamics simulations. Thermal boundary conductance (TBC), i.e. inverse of TBR, was quantified for a range of nanotube lengths by applying a pico-second heat pulse to the SWNT and observing the relaxation. The SWNT-len...

Carbon nanotubes (CNT) are intensively being developed for biomedical applications including drug and gene delivery. Although all possible clinical applications will require compatibility of CNT with the biological milieu, their in vivo capabilities and limitations have not yet been explored. In this work, water-soluble, single-walled CNT (SWNT) have been functionalized with the chelating molec...
