Overview

Simulation study reveals reduced water diffusion and high energetic barriers in hydrophilic nanoconfinement, indicating mechanisms for controlled molecular transport.

Key Points

  • To investigate the dynamic properties, diffusion behavior, and transport energetics of water and ions confined between hydrophilic surfaces at varying nanoscale distances.
  • Performed molecular dynamics simulations modeling water molecules alongside sodium and chloride ions under spatial confinement.
  • Evaluated system behavior across interlayer confinement distances ranging from 7 to 13 Å.
  • Water diffusion decreased progressively with smaller confinement distances due to enhanced hydrogen bonding and restricted molecular motion.
  • Ion transport faced increased nanoscale energetic barriers under narrow confinement, demonstrating significant spatial control over molecular mobility.
