Journal ArticleDOI
Opening carbon nanotubes with oxygen and implications for filling
Pulickel M. Ajayan,Thomas W. Ebbesen,Toshinari Ichihashi,Sumio Iijima,Katsumi Tanigaki,Hidefumi Hiura +5 more
TL;DR: In this paper, it was shown that the oxidation of carbon nanotubes in air for short durations above about 700 °C results in the etching away of the tube caps and the thinning of tubes through layer-by-layer peeling of the outer layers, starting from the cap region.
Journal ArticleDOI
Capillarity and Wetting of Carbon Nanotubes
TL;DR: The wetting and capillarity of carbon Nanotubes were studied in detail here and have important implications for the further use of carbon nanotubes in experiments on a nanometer scale.
Journal ArticleDOI
Superconductivity at 33 K in CsxRbyC60
Katsumi Tanigaki,Thomas W. Ebbesen,S. Saito,Jun'ichiro Mizuki,Jaw-Shen Tsai,Yoshimi Kubo,Sadanori Kuroshima +6 more
TL;DR: In this paper, a superconducting phase of C60 doped with caesium and rubidium was reported, which has the highest transition temperature Tc and the largest diamagnetic shielding found so far for the alkali-metal-doped compounds.
Journal ArticleDOI
Multifunctional Porous Graphene for High‐Efficiency Steam Generation by Heat Localization
TL;DR: The novel 3D nanoporous graphene demonstrates a highly energy-effective steam generation with an energy conversation of 80% in a heat generator to convert solar illumination into high-energy steam.
