A new liquid metal alloy enables sodium-beta batteries to operate at lower temperatures, which could help the batteries store more renewable energy and strengthen the power grid. Sun, wind and other ...

A "straight out of science fiction" liquid membrane developed by a team of Penn State mechanical engineers acts as a "reverse filter" that lets large objects through while blocking small ones. The ...

A new kind of battery stores energy in what researchers are calling “rechargeable fuel”—electrodes in liquid form. The result can be either recharged like a conventional battery or replaced by pumping ...
