Electronic properties of capped, finite-length armchair carbon nanotubes in an electric field

Article Abstract:

The electronic properties of finite-length armchair carbon nanotubes in an electric field (E) using a single pi-band tight-binding model are investigated. Results suggest that the electric field induced a strong modulation of the state energies and energy gaps of the current nanotubes, changes their energy spacings and prompts the occurrence of semiconductor-metal transitions (SMTs).

Direct electrochemistry of uric acid at chemically assembled carboxylated single-walled carbon nanotubes netlike electrode

Article Abstract:

The charge-transfer process and electrode process kinetics is investigated using uric acid as an example by employing carboxylated single-walled carbon nanotubes (SWCNT) chemically assembled on gold substrate as netlike electrode. Results indicate that the surface adsorption-controlled electrochemical process governs electrode process in the carboxylated SWCNT electrode system.

Temperature and size effects on diffusion in carbon nanotubes

Article Abstract:

The dynamics of methane and helium at the zero-loading limit inside carbon nanotubes is investigated. Diffusivities are expected to increase with temperature and this effect is observed for carbon nanotubes distinctly larger than the guest molecules.
