  7. -2.1kBT per water molecule, indepent of tube length S. Vaitheeswaran,J.C.Rasaiah & G. Hummer. J. Chem. Phys.,121,7955(2004).

  8. Temperature effect S. Vaitheeswaran,J.C.Rasaiah & G. Hummer. J. Chem. Phys.,121,7955(2004).

  9. Effect of external field Thermodynamic properties for the modified tube in a uniform electric field E parallel to the tube axis at T=298K

  10. Conclusion Hydrophobic channels can have significant water occupancy despite a reduction in the number of hydrogen bonds compared to the bulk fluid. Small changes in the nanotube-water interactions can lead to large changes in the water occupancy of the channel. Temperature and external field can improve the occupancy probabilities.

  11. Water model TIP3P
