The permeation of K+ and Cl− ions across (7,7) and (8,8) carbon and boron nitride nanotubes was studied by the molecular dynamics simulation method. The simulated systems consist of a carbon or boron nitride nanotubes inserted in a silicon nitride membrane immersed in an aqueous ionic solution. The considered nanotubes were fixed in a silicon–nitride membrane and an external electrical field was applied...
