Journal ArticleDOI

Fabrication of vapor and gas sensors using films of aligned CNx nanotubes

TL;DR: In this paper, the authors demonstrate that pyridine-type regions on the tube surface bind strongly to ammonia, acetone and OH groups, thus altering their density of states, and demonstrate that these regions could be used as fast responsive and reusable sensors.
Journal ArticleDOI

Raman spectroscopy study of isolated double-walled carbon nanotubes with different metallic and semiconducting configurations.

TL;DR: Detailed Raman spectroscopy experiments carried out on individual DWNTs, where both concentric tubes are measured under resonance conditions, are reported, for the first time, to understand the dependence of their electronic and optical properties according to their configuration.
