Molecular dynamics simulation of salt rejection through silicon carbide nanotubes as a nanostructure membrane

A snapshot of the simulated system with size of 34 × 39 × 80 Å3 containing silicon carbide nanotube, silicon nitride membrane, sodium and chloride ions and water molecules. (gray: silicon nitride; yellow: silicon; cyan: carbon; green: Na+; purple: Cl− and red and white: water). Sodium and chloride ions are displayed with van der Waals modes.
