A scalable and facile approach is demonstrated where as-grown patterns of well-aligned structures composed of single-walled carbon nanotubes (SWNT) synthesized via water-assisted chemical vapor deposition (CVD) can be transferred, or printed, to any host surface in a single dry, room-temperature step using the growth substrate as a stamp. We demonstrate compatibility of this process with multip...

Carbon nanotubes have shown great potential as effective adsorbents for hydrophobic organic contaminants in water treatment. The present study investigated the influence of aqueous solution chemistry on the adsorption of tetracycline to carbon nanotubes. Specifically, the effects of ionic strength (NaCl and CaCl(2) ) and presence of Cu(2+) ion (7.5 mg/L) or dissolved soil or coal humic acids (5...

Carbon nanotubes have been explored as heat-delivery vehicles for thermal ablation of tumors. To use single-walled carbon nanotubes (SWNT) as a "molecular heater" for hyperthermia therapy in cancer, stable dispersibility and smart-delivery potential will be needed, as well as lack of toxicity. This paper reports the preparation of a model complex comprising DNA-treated SWNT and anti-human IgG a...

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...
