Comparison of Synchrotron and Laboratory X-ray Sources in Photoelectron Spectroscopy Experiments for the Study of Nitrogen-Doped Carbon Nanotubes

open access: yesQuantum Beam Science, 2023
The chemical composition and stoichiometry of vertically aligned arrays of nitrogen-doped multi-walled carbon nanotubes (N-CNTs) were studied by photoelectron spectroscopy using laboratory and synchrotron X-ray sources. We performed careful deconvolution

Boundary layer chemical vapor synthesis of self-organized radial filled-carbon-nanotube structures

open access: yes, 2013
We report a new chemical vapor synthesis method that exploits random fluctuations in the viscous boundary layer between a laminar vapor flow and a surface to yield a not previously observed product: radial ferromagnetically filled-carbon-nanotube ...

Carbon nanotubes as near infrared laser susceptors

open access: yes, 2011
The coupling efficiency of carbon nanotubes with near infrared laser radiation at 940nm wavelength was investigated. Nanotubes treated with different post processing methods were irradiated at different laser power intensities as dry samples and ...

Influence of the height of carbon nanotubes on hot switching of Au/Cr-Au/MWCNT contact pairs [PDF]

open access: yes, 2014
Gold coated Multi-Walled Carbon Nanotube (MWCNT) composites have been used for electrical contact surfaces in previous studies. It was shown that the composite could significantly improve switch lifetime, and exhibited potential as a useful contact ...

Ordered Arrays of Carbon Nanotubes: From Synthesis to Applications

open access: yesNano Biomedicine and Engineering, 2012
Carbon nanotubes are well known for their unique physical properties, which depend on the dimensions of the nanotubes. It is imperative to develop methods for positioning, orienting, and controlling the diameter and length of CNTs before they can be used

Electrochemistry at nanoscale electrodes : individual single-walled carbon nanotubes (SWNTs) and SWNT-templated metal nanowires [PDF]

open access: yes, 2011
Individual nanowires (NWs) and native single-walled carbon nanotubes (SWNTs) can be readily used as well-defined nanoscale electrodes (NSEs) for voltammetric analysis.

Receptor‐Free Identification of Toxic Gases Enabled by Hygroscopic Aqueous Salt Films

open access: yesAdvanced Functional Materials, EarlyView.
Water as a gas sensor coating sounds impossible—until it stops evaporating. Here, hygroscopic salt solutions (LiCl, LiBr, H3PO4) form non‐drying aqueous films on CNT chemiresistors under ambient air. Gases partition into these liquid layers, sometimes transforming into water, and generate salt‐specific resistance fingerprints across a four‐channel ...

Investigation of charge interaction between fullerene derivatives and single‐walled carbon nanotubes

open access: yesInfoMat, 2019
The charge interaction and corresponding doping effect between single‐walled carbon nanotubes (SWNTs) and various fullerene derivatives, namely, C60, phenyl‐C61‐butyric acid methyl ester (PC61BM), methano‐indenefullerene (MIF), 1′,1″,4′,4″‐tetrahydrodi[1,
