New technique produces longer-lasting lithium batteries

The grand challenge to improve energy storage and increase battery life, while ensuring safe operation, is becoming evermore critical as we become increasingly reliant on this energy source for everything from portable devices ...

New polymer films conduct heat instead of trapping it

Polymers are usually the go-to material for thermal insulation. Think of a silicone oven mitt, or a Styrofoam coffee cup, both manufactured from polymer materials that are excellent at trapping heat.

New coating could have big implications for lithium batteries

Building a better lithium-ion battery involves addressing a myriad of factors simultaneously, from keeping the battery's cathode electrically and ionically conductive to making sure that the battery stays safe after many ...

A hydrogel that can stop bleeding from an artery

A team of researchers affiliated with several institutions in China has developed a hydrogel that can stop bleeding from a punctured artery. In their paper published in the journal Nature Communications, the group describes ...

Radical desalination approach may disrupt the water industry

Hypersaline brines—water that contains high concentrations of dissolved salts and whose saline levels are higher than ocean water—are a growing environmental concern around the world. Very challenging and costly to treat, ...

Squid skin inspires creation of next-generation space blanket

Drawing design inspiration from the skin of stealthy sea creatures, engineers at the University of California, Irvine have developed a next-generation, adaptive space blanket that gives users the ability to control their ...
