Membranes

Daniel Akst of The Wall Street Journal writes about new MIT findings that could make pressure-retarded osmosis (PRO) a more feasible technique for producing power from two streams of different salinity.

NPR’s Joe Palca reports on MIT Professor Rohit Karnik’s work to develop a cheap and effective way to filter water. Karnik’s new solution is a filter made from a pinewood branch peeled of its bark.

Boston Globe reporter Carolyn Johnson writes that Professor Rohit Karnik has developed a, “promising next-generation water filter that might be effective, cheap, and biodegradable.”

“The function of xylem's filtration formed the basis of a paper published this week by a team from the Massachusetts Institute of Technology,” Jason Tetro writes of Rohit Karnik’s work with water filtration in the Huffington Post. “The premise was that xylem could help to filter water and make it safe to drink.”
