LEDs are small but powerful components that light up everything from phone screens to flashlights. In this video, you'll learn how a tiny chip inside an LED converts electrical energy into light using ...

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 ...

For the first time, researchers in China have demonstrated a high-temperature superconducting diode effect, which allows a ...

Look inside a science fiction computer, and you’ll probably see tubes and cubes that emit light. Of course, it’s for effect, ...

I had this idea of building my own bicycle lighting system totally personalized, the lights would have the exact lighting ...

Using an optoelectronic transistor as the tetrachromatic sensor, the system can simultaneously process spectral, spatial, and ...

Abstract: This paper presents an effective on-chip integration of a GaN-based metal-oxide-semiconductor field-effect transistor (MOSFET) and an ultraviolet light-emitting diode (UV LED) on a GaN-on-Si ...

My initial goal was to have a remote display that would show multiple kind of information and run reliably 24/7. Can be connected to the local network via WiFi and controlled via REST API or Websocket ...

Abstract: This study investigated different layer thicknesses of HfO2/ZrO2 superlattice (SL HZO) as gate oxides. Metal-insulator-semiconductor (MIS) and metal-insulator-metal (MIM) capacitors were ...

Red light therapy is booming. Previously reserved for in-clinic treatments, there are now plenty of at-home options. It’s become strangely normal to see pictures of people peering out from beneath ...
