The experimental creation and annihilation of defects on single-walled carbon nanotubes (SWCNT) with the tip of a scanning tunneling microscopeare reported. The technique used to manipulate the wall structure of a nanotube at the atomic scale consists of a voltage ramp applied atconstant tunneling current between the tip and the nanotube adsorbed on a gold substrate. While topographic i...

A novel electrochemical immunosensor for the detection of matrix metalloproteinase-3 (MMP-3), a cancer biomarker protein, based on vertically aligned single-wall carbon nanotube (SWCNT) arrays is presented. Detection was based on a sandwich immunoassay consisting of horseradish peroxidase (14-16 labels) conjugated to a secondary antibody and/or a polymer bead loaded with multi-enzyme labels. Pe...

We report on passive mode-locking of a Ti:sapphire laser employing a single-walled carbon nanotube saturable absorber (SWCNT-SA) specially designed and fabricated for wavelengths near 800 nm. Mode-locked pulses as short as 62 fs were generated at a repetition rate of 99.4 MHz. We achieved output powers from the SWCNT-SA mode-locked laser as high as 600 mW with a slope efficiency of 26%. The cha...

Epoxy/Single Walled Carbon Nanotube Nanocomposite Thin Films for Composites Reinforcement. (May 2009) Graham Leicester Warren, B.S., Texas A&M University Chair of Advisory Committee: Dr. Hung-Jue Sue This work is mainly focused upon the preparation, processing and evaluation of mechanical and material properties of epoxy/single walled carbon nanotube (SWCNT) nanocomposite thin films. B-staged e...

We review the recent progress in thermal characterization and sensor applications of one-dimensional nanostructures employing microelectromechanical system (MEMS) devices. It was found by thermal measurements that the thermal conductance of a single wall carbon nanotube (SWCNT) was very close to the ballistic thermal conductance of a 1-nm-diameter SWCNT without signatures of phonon-phonon Umkla...

In this paper, single wall carbon nanotube (SWCNT) suspensions were added dropwise to silica particles before volatising the solvent to prepare a core-shell composite adsorbent with SWCNTs wrapped around silica particles (SWCNTs@Silica). The composite adsorbent was used as packing for the solid phase extraction (SPE) and the enrichment of organophosphorus pesticides (OPPs) in water. The results...

Introduction of defects via ion irradiation ex situ to modify silver/single-wall carbon nanotube (Ag-SWCNT) electrical contacts and the resulting changes in the electrical properties were studied. Two test samples were fabricated by depositing 0.1 μm Ag onto SWCNT thin films with average thicknesses of 10 and 60 nm, followed by ion irradiation (150 keV 11B+ at 5 × 1014 ions/cm2). The contact re...

By using MD simulation method, this study shows the influences of cooling rates on solidifying temperature water inside a single-wall-carbon-nanotube under different ambient pressures when systems from 300 K down to 200 K. Our results showed that more rapid rate creates disruptive and dramatic phase transitions. Moreover, we also found lower correlates transitions water, regardless rate. This g...

A novel immobilized fullerene–single wall carbon nanotube (C60–SWCNT) complex was synthesized via a microwave induced functionalization approach. It has been used as a component of the photoactive layer in a bulk heterojunction photovoltaic cell. As compared to a control device with only C60, the addition of SWCNTs resulted in an improvement of both the short circuit current density JSC and the...

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...
