- 1 November 1991
THE synthesis of molecular carbon structures in the form of C60 and other fullerenes1 has stimulated intense interest in the structures accessible to graphitic carbon sheets. Here I report the…
Single-shell carbon nanotubes of 1-nm diameter
CARBON nanotubes1 are expected to have a wide variety of interesting properties. Capillarity in open tubes has already been demonstrated2–5, while predictions regarding their electronic structure6–8…
Roll-to-roll production of 30-inch graphene films for transparent electrodes.
The roll-to-roll production and wet-chemical doping of predominantly monolayer 30-inch graphene films grown by chemical vapour deposition onto flexible copper substrates are reported, showing high quality and sheet resistances superior to commercial transparent electrodes such as indium tin oxides.
Water-Assisted Highly Efficient Synthesis of Impurity-Free Single-Walled Carbon Nanotubes
Water-stimulated enhanced catalytic activity results in massive growth of superdense and vertically aligned nanotube forests with heights up to 2.5 millimeters that can be easily separated from the catalysts, providing nanotubes material with carbon purity above 99.98%.
Structural flexibility of carbon nanotubes
We report high resolution electron microscope (HREM) observations and atomistic simulations of the bending of single and multi‐walled carbon nanotubes under mechanical duress. Single and multiple…
Shape-engineerable and highly densely packed single-walled carbon nanotubes and their application as super-capacitor electrodes
This dense carbon-nanotube material is advantageous for numerous applications, and here it is demonstrated its use as flexible heaters as well as supercapacitor electrodes for compact energy-storage devices.
Fabrication of a freestanding boron nitride single layer and its defect assignments.
A freestanding single layer of hexagonal boron nitride (h-BN) has been successfully fabricated by controlled energetic electron irradiation through a layer-by-layer sputtering process and the dominating zigzag-type edges are proved to be nitrogen terminated.
