(Phys.org) —Researchers have demonstrated a new class of high-energy battery, called a "molten-air battery," that has one of the highest storage capacities of any battery type to date. Unlike some other high-energy batteries, ...
(Phys.org)—Over the past few years, Li-air batteries (more precisely, Li-oxygen batteries) have become attractive due to their theoretical ability to store nearly as much energy per volume as gasoline. The key to this high ...
(PhysOrg.com) -- For many years, researchers have been working on designing and fabricating micro-air-vehicles (MAVs), flying robots the size of small insects. But after realizing how difficult it is to create a tiny, lightweight ...
Extending California's stringent diesel emissions standards to the rest of the U.S. could dramatically improve the nation's air quality and health, particularly in lower income communities of color, finds a new analysis published ...
