Solar-powered desalination unit shows great promise

Despite the vast amount of water on Earth, most of it is nonpotable seawater. Freshwater accounts for only about 2.5% of the total, so much of the world experiences serious water shortages.

New technique lets researchers map strain in next-gen solar cells

People can be good at hiding strain, and we're not alone. Solar cells have the same talent. For a solar cell, physical strain within its microscopic crystalline structure can interrupt its core function—converting sunlight ...
