Abstract:We also performed studies on ion selectivity in BNNTs. Specifically, we showed that a finite length (10,10) BNNT with a diameter of 1.356 nm immersed in a reservoir of 1M KCl solution can selectively conduct Cl- ions, while K+ ions barely reach the center of the nanotube and do not conduct. In contrast, a (10,10) single-walled carbon nanotube of approximately the same diameter immersed in a 1M KCl solution can selectively conduct K+ ions through the nanotube. Finally, we also improve the water-BNNT Lennard-Jones (LJ) parameters by using ab initio methods and molecular dynamics simulations. With modified LJ parameters, molecular dynamics simulations of water droplet on hexagonal boron nitride sheet are carried out to determine water contact angle.
