Abstract:

We investigate how to control the net flux of oxygen molecule transportation through a carbon nanotube (CNT). We find that the net flux of oxygen molecules in a nanotube increases linearly when the diameter of the nanotube becomes big and that an N-doped nanotube has a bigger net flux of oxygen molecules than a pure carbon nanotube.

Key words: flux, free energy, transportation, molecular dynamics
