Nanotechnology Now Abstract: A desalination membrane acts as a filter for salty water: push the water through the membrane, get clean water suitable for agriculture, energy production and even drinking. The process seems simple enough, but it contains complex intricacies that have baffled scientists for decades until now. Controlling the nanoscale structure of membranes is key for clean water, researchers find University Park, PA | Posted on January 1st, 2021 Researchers from Penn State, The University of Texas at Austin, Iowa State University, Dow Chemical Company and DuPont Water Solutions published a key finding in understanding how membranes actually filter minerals from water, online today (Dec. 31) in Science. The article will be featured on the print edition s cover, to be issued tomorrow (Jan. 1). ....
12-31-2020 By Earth.com staff writer Breakthrough may greatly improve the production of clean water. In a new study led by the University of Texas at Austin, experts have had a breakthrough that may help produce clean drinking water at a lower cost. The researchers solved a complex problem that has baffled scientists for decades. Desalination membranes remove salt and other chemicals from water, cleaning billions of gallons of water for agriculture. While the concept seems simple, the process of desalination is actually very complex and not well understood. In collaboration with DuPont Water Solutions, the researchers have solved an important aspect of this mystery, opening the door to reduce costs of clean water production. ....
Researchers discover new insights into how water filter membranes work Shane McGlaun - Jan 1, 2021, 6:03am CST Scientists have known for years that membranes can do things such as act as a filter for saltwater. When salty ocean water is moved through a membrane, clean water comes out the other side that can be used for agriculture and drinking, among other things. While pushing water through a membrane is a simple enough process, the exact method that allowed water filtration membranes to work was unknown until now. A group of researchers, including scientists from Penn State, the University of Texas at Austin, Iowa State University, Dow Chemical Company, and DuPont Water Solutions, have now published a study showing key findings and how membranes filter minerals from water. Researcher Enrique Gomez, professor of chemical engineering and materials science and engineering at Penn State, research lead, says that the team found that how the density dist ....
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. This 3D model of a polymer desalination membrane shows water avoiding dense spots in the membrane and slowing flow; red above the membrane shows water under higher pressure and with higher concentrations of salt; the gold, granular, sponge-like structure in the middle shows denser and less-dense areas within the salt-stopping membrane; silver channels show how water flows through; and the blue at the bottom shows water under lower pressure and with lower concentrations of salt.
