Effects of nitrogen-doping on the microstructure, bonding and electrochemical activity of carbon nanotubes

TL;DR: In this paper, the effects of N-doping on carbon nanotubes have been systematically investigated via microstructure and bonding studies, electron-transfer (ET) behaviors, and subsequent electrochemical deposition of catalyst.
Journal ArticleDOI

Search for heavy quarks decaying into a top quark and a W or Z boson using lepton + jets events in pp collisions at √s = 7 TeV

S. Chatrchyan, +2345 more
TL;DR: In this paper, a search for the pair-production of heavy quarks, Q Q-bar, that decay exclusively into a top quark and a W or Z boson was performed using a sample of proton-proton collisions at 7 TeV corresponding to an integrated luminosity of 5.0 inverse femtobarns, collected by the Compact Muon Solenoid experiment.
Journal ArticleDOI

Structural and optical properties of single crystal Zn1-xMgxO nanorods - Experimental and theoretical studies

TL;DR: In this paper, structural and optical properties of single crystal Zn1−xMgxO nanorods (0≤x≤0.17) are studied experimentally and theoretically.
Journal ArticleDOI

Highly efficient nitrogen and carbon coordinated N–Co–C electrocatalysts on reduced graphene oxide derived from vitamin-B12 for the hydrogen evolution reaction

TL;DR: In this article, acid treated pyrolyzed vitamin B12 supported on reduced graphene oxide (B12/G800A) showed an extraordinarily enhanced catalytic activity with low overpotential (115 mV vs. RHE at 10 mA cm−2), which is better than that of most traditional nonprecious metal catalysts in acidic media.
Journal ArticleDOI

Edge promoted ultrasensitive electrochemical detection of organic bio-molecules on epitaxial graphene nanowalls.

TL;DR: The unique edge dominant EGNWs result in an unprecedented low limit of detection (experimental) of 0.033 nM and highest sensitivity of 476.2 µA/µM/cm(2), for UA, which are orders of magnitude higher than comparable existing reports.
