Competition between hydrogen bonding and electric field in single-file transport of water in carbon nanotubes
hydrogen bonding and electric field single-file transport carbon nanotubes
2011/9/15
Recent studies have shown the possibility of water transport across carbon nanotubes, even in the case of nanotubes with small diameter (0.822 nm). In this case, water shows subcontinuum transport fol...
