Journal ArticleDOI

Nanotube molecular wires as chemical sensors

Jing Kong, +6 more
- 28 Jan 2000 - 
TL;DR: The nanotubes sensors exhibit a fast response and a substantially higher sensitivity than that of existing solid-state sensors at room temperature and the mechanisms of molecular sensing with nanotube molecular wires are investigated.
Journal ArticleDOI

Crystalline Ropes of Metallic Carbon Nanotubes

Andreas Thess, +14 more
- 26 Jul 1996 - 
TL;DR: X-ray diffraction and electron microscopy showed that fullerene single-wall nanotubes (SWNTs) are nearly uniform in diameter and that they self-organize into “ropes,” which consist of 100 to 500 SWNTs in a two-dimensional triangular lattice with a lattice constant of 17 angstroms.
Journal ArticleDOI

Co3O4 nanocrystals on graphene as a synergistic catalyst for oxygen reduction reaction

Yongye Liang, +6 more
- 01 Oct 2011 - 
TL;DR: The Co₃O₄/N-doped graphene hybrid exhibits similar catalytic activity but superior stability to Pt in alkaline solutions, making it a high-performance non-precious metal-based bi-catalyst for both ORR and OER.
Journal ArticleDOI

Chemically Derived, Ultrasmooth Graphene Nanoribbon Semiconductors

Xiaolin Li, +4 more
- 29 Feb 2008 - 
TL;DR: A chemical route to produce graphene nanoribbons with width below 10 nanometers was developed, as well as single ribbons with varying widths along their lengths or containing lattice-defined graphene junctions for potential molecular electronics.
Journal ArticleDOI

MoS2 Nanoparticles Grown on Graphene: An Advanced Catalyst for the Hydrogen Evolution Reaction

Yanguang Li, +5 more
- 21 Apr 2011 - 
TL;DR: In this article, a selective solvothermal synthesis of MoS2 nanoparticles on reduced graphene oxide (RGO) sheets suspended in solution was developed, which exhibited superior electrocatalytic activity in the hydrogen evolution reaction (HER).
