Selective removal of metallic single-walled carbon nanotubes with small diameters by using nitric and sulfuric acids

Article Abstract:

A selective removal of m-SWCNTs (single walled carbon nanotubes) with small diameters is reported by using HNO3/H2SO4 solution, which could be achieved by adjusting the treatment conditions. The result can be explained by the charge transfer from m-SWNCTs to NO2(super +) dissolved in the HNO3/H2SO4 solution in good agreement with the theoretical calculations.

Density functional theory study of NO adsorbed in A-zeolite

Article Abstract:

Density theory was employed to investigate the adsorption site and hyperfine interactions of nitric oxide adsorbed in Na-LTA (NaA) zeolite. The successful modeling of the NO radical interaction with the zeolite frameworks finds out many possibilities for further theoretical studies in the area.
