Energy barriers to anion transport in nanofiltration membranes: Role of intra-pore diffusion. “Understanding how membrane structure affects selectivity is key to fabricating next-generation membranes for water treatment. We found that ion selectivity of nanofiltration membranes is
independent of membrane thickness. Instead, the primary energy barrier to ion transport arises at the water-membrane interface" NEWT student, Ryan DuChanois explains.
