Scholarcy highlights

  • The transport of water molecules through nanopores is crucial to biological activities and useful for designing novel nanofluidic devices
  • The Altmetric Attention Score is a quantitative measure of the attention that a research article has received online
  • In this paper, using molecular dynamics simulations, we systematically investigate the effects of an external electric field on the transport of single-file water molecules through a carbon nanotube
  • We find that the orientation of water molecules inside the CNT can be well-tuned by the electric field and is strongly coupled to the water flux
  • This orientation-induced water flux is energetically due to the asymmetrical water−water interaction along the CNT axis
  • The water flux is increased as E is increased for E ≤ Ec, while it is almost unchanged for E > Ec
  • Water Molecules in a Carbon Nanotube under an Applied Electric Field at Various Temperatures and Pressures
