Probing the Electronic Effect of Carbon Nanotubes in Catalysis: NH3 Synthesis with Ru Nanoparticles
TL;DR: The dissociative adsorption of N(2), which is an electrophilic process and the rate-determining step of ammonia synthesis, is more facile over the outside Ru than that over the inside one.

A Carbon Nanotube Field-Emission Electron Source
TL;DR: In this paper, a high-intensity electron gun based on field emission from a film of aligned carbon nanotubes has been made, which consists of a nanotube film with a 1-millimeter-diameter grid about 20 micrometers above it.
