Sponge-like pore (cellular pore) structure of ultrafiltration membrane has special advantages on rejection and anti-pressure performance. The cover by Lei Zhang and colleagues shows a SEM image of spongelike pore structure of PES UF membrane, which was prepared by adding some non-solvent additives. The membrane with fully sponge-like structure retained good operation stability for long time at high pressure. Inevitably, the permeate flux was decreased because of greater mass transfer resistance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
