Physics training taught Brian Gerke how to figure out anything; now he’s applying his skills to energy-efficiency research, helping to set national standards. Brian Gerke follows the second law of ...

Scientists have developed a new model that explains how photon efficiency changes at higher wavelengths, paving the way for a more efficient quantum internet. Reading time 2 minutes Materials ...

The efficiency of perovskite LEDs (PeLEDs) is limited by electron traps that form due to structural defects. While defect passivation – the science of neutralizing these traps often with molecules – ...

ABB recently set a new world record for industrial motor efficiency of 99.13%. But what's behind this breakthrough, and how close are we to reaching the practical limits of electric motor efficiency?
