A solar cell moonlights as an LED, both absorbing and emitting light more efficiently
Imagine a display that harvests ambient light when it is not actively in use, offsetting some of its own energy consumption. Materials physics shows that this is possible; the same semiconductor ...
At-home LED devices, particularly those that combine red and blue light, are efficacious for acne and can likely complement other over-the-counter and prescription treatments. HealthDay News — At-home ...
