Power generator that runs on natural atmospheric humidity

Device uses nano-sized polyoxometalates. Scientists are looking for ways to use the low-value energy widely distributed in natural environments to generate electricity. A research team has created a power generator…

One step closer to lithium metal batteries

…that function with minimal external pressure. New stand-alone thin-film version of the solid-state electrolyte called lithium phosphorus oxynitride (LiPON) shows promise in functional battery tests. A team of battery researchers…

A molecular additive enhances next-gen LEDs

– but shortens their lifespans. Tinkering with the makeup of inexpensive LED lights boosted their brightness and efficiency, but the new lights only lasted a few minutes. Chances are, the…

Batteries on wheels

New charging technology to make e-cars suitable for mass use as mobile power storage units. Bidirectional charging enables electric vehicles to be both charged and discharged as needed. E-cars can…

Energy-storing supercapacitor from ancient materials

Made of cement, carbon black, and water, the device could provide cheap and scalable energy storage for renewable energy sources. Two of humanity’s most ubiquitous historical materials, cement and carbon…

Fusion model hot off the wall

Predicting molecular rotational temperature for enhanced plasma recombination. Humans may never be able to tame the Sun, but hydrogen plasma — making up most of the Sun’s interior — can…
