As electric vehicles (EVs) and smartphones increasingly demand rapid charging, concerns over shortened battery lifespan have ...

Hybrid electric vehicles, cell phones, digital cameras, and the Mars Curiosity rover are just a few of the many devices that use rechargeable lithium-ion batteries. Now a team of researchers has a ...

Scientists have discovered how to keep a promising new type of lithium ion battery cathode from developing a crusty coating that degrades its performance. The solution: Use a simple manufacturing ...

Symmetry breaking phase transitions play an important role in nature. When a system traverses such a transition at a finite rate, its causally disconnected regions choose the new broken symmetry state ...

A spacecraft thruster that relies on iodine has been successfully tested in an orbiting satellite (Nature 2021, DOI: 10.1038/s41586-021-04015-y). The propulsion system is a form of ion drive, which ...

Salt lamps, because they emit negatively charged ions, impart myriad health benefits including reduced anxiety, improved sleep, increased energy, and protection from an “electric smog.” Salt lamps, ...
