A facile "scratching" method to pattern a catalyst with commonly used metal objects, such as blade, pen cover, tweezers, watchband, knife, key, clamp, and coin, was developed. The single-walled carbon nanotube (SWCNT) networks and well-aligned SWCNT arrays successfully grew by chemical vapor deposition on the scratched catalyst patterns on Si/SiO(x) and quartz, respectively. This method provide...

Wet individual Single walled carbon nanotube was observed at an atomic level with high resolution. This observation was achieved in a liquid cell containing water using a modified non-contact mode atomic force microscopy (NC-AFM) which, we believed, becomes the powerful tool for imaging nano-material in atomic scale. Consequently, the topography image showed many hexagons network of carbon atom...

Monte Carlo simulations of coronene molecules in single-walled carbon nanotubes (SWCNTs) and dicoronylene molecules in SWCNTs are performed. Depending on the diameter D of the encapsulating SWCNT, regimes favoring the formation of ordered, one-dimensional (1D) stacks of tilted molecules (D ≤ 1.7 nm for coronene@SWCNT, 1.5 nm ≤ D ≤ 1.7 nm for dicoronylene@SWCNT) and regimes with disordered molec...

A review is presented on the resonance Raman spectra from one isolated single wall carbon nanotube. The reasons why it is possible to observe the spectrum from only one nanotube are given and the important structural information that is provided by single nanotube spectroscopy is discussed. Emphasis is given to the new physics revealed by the various phonon features found in the single nanotube...

First principles calculations were carried out for investigation the novel 7-hydroxycoumarinyl gallates derivatives in gas and liquid phases using density functional theory (DFT) method. Computational chemistry simulations were carried out to compare calculated quantum chemical parameters for gallates derivatives. All calculations were performed using DMol3 code which is based on DFT. The Doubl...

In this paper, the integration of a flexible RFID tag with an inkjet-printed Single Walled Carbon Nanotube (SWCNT) film in a chipless sensor node for toxic gas detection was introduced for the first time. The whole module is realized on a "green" low-cost paper substrate. Carbon nanotube composites change their electric properties (e.g. resistance, dielectric properties) in the presence of very...

Using molecular dynamics simulations, we investigate systematically the water permeation properties across single-walled carbon nanotubes (SWCNT) in the presence of the terahertz electric field (TEF). With the TEF normal to the nanotube, the fracture of the hydrogen bonds results in the giant peak of net fluxes across the SWCNT with a three-fold enhancement centered around 14 THz. The phenomeno...

Modulation of electronic structures and surface properties of transparent carbon nanotube films is a challenging issue for their application in optoelectronic devices. Here, we report, for the first time, that graphene oxide (GO) nanosheets play the role of a p-doping agent and surface energy modifier of single-walled carbon nanotube (SWCNT)-based transparent conducting electrodes (TCEs). The d...

The ultraviolet optical properties of semiconducting-enriched and metallic-enriched single-walled carbon nanotube (semi-enriched and m-enriched SWCNT) networks were studied using spectroscopic ellipsometry. According to calculated energy loss function, the energy loss peak assigned to the maximum intensity of π-plasmon energy was found to increase from 4.5 eV to 5.0 eV as SWCNT network composit...

Polyiodide species were synthesized by the acceleration of an acidic environment in nanospace single-walled carbon nanotubes (SWCNT) with light irradiation. Raman and EXAFS results strongly support production polyiodide after adsorption CsI on SWCNT from aqueous solution. Interestingly, reaction was initiated nano-confined phase formed a basic environment. The plays essential role as oxidant fo...
