Very small pores make a big difference in filtering technology

Nanoporous membranes have been shown to be valuable tools for filtering out impurities from water and numerous other applications. However, there's still much work to be done in perfecting their designs. Recently, the lab of Prof. Amir Haji-Akbari has demonstrated that exactly where the nanosized holes are placed on the membrane can make a big difference. The results are published in ACS Nano.
