Dermatologists explain the science behind wildly popular treatments like red light therapy, which is now available at home—for a steep price. Full-face LED masks like this one can cost up to several ...

Abstract: This paper reports proton damage in light-emitting diode (LED) and phototransistor of the Micropac 66296 optocoupler. Our results show that the optocoupler current transfer ratio (CTR) data ...

Researchers from the Department of Physics in the College of Science and the James C. Wyant College of Optical Sciences, all at the University of Arizona, have demonstrated a way to manipulate ...

What if ultrafast pulses of light could operate computers at speeds a million times faster than today's best processors? A team of scientists, including researchers from the University of Arizona, are ...

Scientists are exploring ultrafast light pulses to power computers that could run a million times faster than today's top processors. (Nanowerk News) What if ultrafast pulses of light could operate ...

The devices, which operate on a heterojunction-gated (HG) structure, demonstrate high responsivity and detectivity while maintaining a simplified fabrication process. This approach avoids the ...

A typical reflective object sensor consists of an infrared light emitter diode (IRED) and an NPN silicon phototransistor mounted side-by-side on parallel axes in a compact black plastic housing. The ...

Having a solid pair of LED headlights can transform the look of your car and visibility. They beat traditional stock headlights, and even upgraded halogens. This is due to having a higher lumen count, ...

British inventors began experimenting with electric lighting in the 1830s, working on so-called arc lamps, while other scientists around the world focused on developing a functioning incandescent lamp ...
