Separation of nitrate ion from water using silicon carbide nanotubes as a membrane: Insights from molecular dynamics simulation

A snapshot of the simulated system with size of 34 × 39 × 80 Å3 containing silicon carbide nanotubes, silicon nitride membrane, nitrate sodium and ions and water molecules. (Sodium: green, nitrogen: blue, yellow: silicon, cyan: carbon, oxygen: red and hydrogen: white). Nitrate and sodium ions are displayed with van der Waals modes.497
