Ideal for reducing maintenance and energy costs as well as handling harsh environments, a family of wedge-based LED lamps from JKL Lamps (Pacoima, CA) provides a performance improvement over ...
Artificial light, once a luxury, has become central to modern life, with its evolution spanning from fire to LEDs. Now, researchers have developed a new class of efficient light-emitting materials as ...
Room-temperature MASERs (Microwave Amplification by Stimulated Emission of Radiation) amplify electromagnetic waves at microwave frequencies with minimal noise. We demonstrate a cost-effective ...
When exposed to light, organic photochromic molecules undergo a fast and reversible change in their electronic structure, resulting in a shift in colour. Solid-state composites of these photochromes ...
