The stress hormone cortisol could be detected accurately by a straightforward bedside test, according to researchers at Rutgers University. They are using an electrode coated in an antibody that binds with cortisol to do the detection, and needed the counter electrode to be really close to keep sensitivity high and noise low. At a few ...

Lithium-metal batteries can last for 600 cycles, according to the US Department of Energy’s Pacific Northwest National Laboratory. “It’s a big step forward for a promising technology, but lithium-metal technology is not yet ready for prime time. While the lithium-ion batteries used in electric vehicles today hold less energy, they last longer, typically at least 1,000 ...

UCLA engineers have monolithically integrated a boron arsenide heat spreader into a GaN HEMT logic chip to improve cooling. At the same time they built similar chips with diamond and silicon carbide heat spreaders. The diamond and SiC circuits had hotspots at around 137°C and 167°C respectively, according to the university, while those in the BAs-cooled ...
