Parameterization of Theoretical Methods in the Calculation of   Nano-expulsion Energies
  The present work encompasses an investigation of the adsorption properties of small dimer species onto a zigzag single walled carbon nanotube (ZNT for short). To perform this analysis we have considered the zigzag (8, 0) system with a length of 13.5 angstroms that has a diameter of 6.3 angstroms. Various theoretical DFT and ab initio approaches were used to attempt to parameterize an ideal method for the calculation of expulsion energies for nanotube species.
