Comparative study of hydrogen adsorption on carbon and BN nanotubes

Article Abstract:

The physisorption and chemisorption of hydrogen in boron nitride (BN) nanotubes are examined by density functional theory and compared with carbon nanotubes. The results have shown that perfect BN nanotubes are not good candidates for hydrogen storage by either mechanism and hence other strategies should be employed if BN nanotubes are to be employed as hydrogen storage media such as using them as supporting media for hydrogen-absorbing metal nanoclusters.

True nanocable assemblies with insulating BN nanotube sheaths and conducting Cu nanowire cores

Article Abstract:

Density functional theory (DFT) investigations on nanocable models comprised of BN nanotubes filled with close-packed Cu nanowires showed that the interactions between these components are weak. The electronic band structures of the BN/Cu nanocables are superposition of the electronic bands of the isolated individual systems, and therefore, electronic transport will occur in the inner Cu nanowires while outer BN nanotubes act as insulating sheaths.
