10. From the mass spectroscopy of the species outgassed from the nanotube-zeolite sample and the Raman spectroscopy, we conclude that there are no hydrocarbon groups and thus no other organic species in our samples.

17. 55N for (4, 2). The tubes in the supercells are aligned in a hexagonal array with the closest distance between adjacent tubes being 10 A. We use a plane-wave pseudopotential approach and the Perdew-Wang-91 generalized gradient corrections. All atomic degrees of freedom are fully relaxed We found that it is about 0.5 eV more favorable for N to substitute a carbon site in (4, 2) than in (3, 3).
