A safe way to bring down rogue drones

Forget nets, attack drones, or lasers – Korean researchers have found a way to coax rogue drones out of the sky – at least, most of those flying on GPS autopilot. “This technology can safely guide a drone to a desired location without any sudden change in direction in emergency situations,” according to national research ...

Pb-free perovskite for solar is stable in air

US researchers have used a supercomputer to discover a candidate for Pb-free perovskite solar cells – most solar perovskites contain Pb-halides, and are unstable in moist air. KBaTeBiO6 is the material, a bismuth-halide double perovskite that was the most promising of 30,000 candidate bismuth-containing oxides postulated by a team of engineers at Washington University in St ...
