Biological membranes can achieve remarkably high permeabilities while maintaining ideal selectivities by relying on homogeneous internal structures in the form of membrane proteins. In new research, a team of scientists led by Penn State University and the University of Texas at Austin applied such design strategies to desalination polyamide membranes.

Dr. Enrique Gomez, Dr. Manish Kumar and their colleagues from Iowa State University, Penn State University, the University of Texas at Austin, DuPont Water Solutions, and Dow Chemical Co. found that creating a uniform membrane density down to the nanoscale of billionths of a meter is crucial for maximizing the performance of reverse-osmosis, water-filtration membranes.
