LED lighting has shifted from niche to mainstream in controlled environment agriculture, driven by improved spectrum, output, and cost reductions. Energy efficiency of LEDs allows growers to achieve ...

If you never answer your phone anymore, I don't blame you. Thanks to robocalls, scammers, and unknown callers, who would want to pick up? You don't have to put up ...

During femtosecond laser fabrication, photons are mainly absorbed by electrons, and the subsequent energy transfer from electrons to ions is of picosecond order. Hence, lattice motion is negligible ...

Researchers have developed a new metasurface-based antenna that represents an important step toward making it practical to harvest energy from radio waves, such as the ones used in cell phone networks ...
