Growth of a cup-stacked carbon nanotube carpet with a superhydrophobic surface
New Carbon Materials, 2013A carpet structure composed of high purity cup-stacked carbon nanotubes (CSCNTs) was synthesized by a catalytic chemical vapor deposition method. In a 15-min growth time, the CSCNT carpet with a height up to ∼300 μm and carbon purity above 99.9 wt.% was prepared.

The activation and hydrogen storage characteristics of the cup-stacked carbon nanotubes
Diamond and Related Materials, 2019Abstract In this study, the cup-stacked carbon nanotubes (CSCNTs) are chemically modified and used for the hydrogen storage for the first time. The SEM and TEM analyses indicate that because they are formed by the stacking of the truncated conical graphene layers the inner- and outer-edges of which are completely exposed, during KOH activation the ...

Processing and characterization of epoxy nanocomposites reinforced by cup-stacked carbon nanotubes
Polymer, 2005The effect of the dispersion, ozone treatment and concentration of cup-stacked carbon nanotubes on mechanical, electrical and thermal properties of the epoxy/CSCNT nanocomposites were investigated. Ozone treatment of carbon fibers was found to increase the surface oxygen concentration, thereby causing the contact angle between water, epoxy resin and ...

Exposed Edge Planes of Cup-Stacked Carbon Nanotubes for an Electrochemical Capacitor
Journal of Physical Chemistry Letters, 2010The end sites of graphitic planes and their catalytic, chemical, physical, and electrochemical roles have been a longstanding issue in the surface chemistry of carbon science. In this study, complete exposure of the active edge sites on the outer surface of catalytically grown cup-stacked carbon nanotubes is accomplished using a conventional ...

Influence of Participation in a Cup-Stacking Unit on Timing Tasks
Perceptual and Motor Skills, 2005Cup stacking is a relatively new activity which has been promoted at conferences for physical educators as having many direct and indirect benefits, such as improved quickness. This study examined the influence of a cup-stacking instructional unit on reaction and anticipation times of 69 children in Grades 2 and 4.

One-dimensionality of phonon transport in cup-stacked carbon nanofibers
Journal of Physics: Condensed Matter, 2010We treat the ballistic heat conduction of cup-stacked carbon nanofibers (CSCNF) by a nonequilibrium molecular dynamics simulation. The CSCNF consist of numerous tiny graphene cups linked in line by weak intermolecular forces. The simulation results show that the thermal conductivity varies with the fiber length in a power law fashion with an exponent ...

Cup‐Stacked Carbon Nanotube Schottky Diodes for Photovoltaics and Photodetectors
Advanced Materials, 2014High performance optoelectronic devices based on cup-stacked carbon nanotubes are realized. Based on a Schottky barrier model, rectifying behaviors and high photoresponse are observed by using growth catalysts as nanoscale electronic contacts. Similar performances are also obtained and furthermore tuned by using nanotube’s defective surface as ...

Controlled synthesis of uniform cup-stacked carbon nanotubes for energy applications
Journal of Alloys and Compounds, 2021Abstract While carbon nanotubes (CNTs) have been widely used for various energy storage and conversion applications, controlled synthesis of CNTs with desired properties at low cost is still a challenge. Here we report our findings in the development of a controlled synthesis of uniform cup-stacked carbon nanotubes (CSCNTs) using a chemical vapor ...
