Scientists discover new behavior of membranes that could lead to unprecedented separations

"separate out different size solutes... isoporous membranes: all pores same size... hindered transport: fluid medium's internal resistance as solute attempts to go through pore... pores approximately 10 nm diameter, separate solutes with as little as a 5% size difference... solutes get multiple attempts to get through membrane... given longer time, or more likely an improved process design, we believe we will see a clear, sharp separation right where the pore size matched the solute size"
