Energy efficiency in physics is not measured the way most people think about it. Instead of asking how much heat a process ...

Perovskite solar cells have surged from laboratory curiosities to serious contenders against silicon in barely a decade, yet the physics behind their remarkable energy harvesting has remained partly ...

Despite being riddled with impurities and defects, solution-processed lead-halide perovskites are surprisingly efficient at ...

There are roof shapes and ratios that maximize heat retainment and energy efficiency and, interestingly, ancient Italian architects and builders seemed to know it, too. While serving as a visiting ...
