FlashESP is a web-based tool allowing the development of Arduino sketches and firmware flashing for ESP32 and ESP8266 hardware platforms. I initially thought it was similar to ESP Web Tools for ...

Abstract: Perovskite nanocrystals (NCs) have shown great potential in flexible light-emitting diodes (LEDs) due to their ease of synthesis and excellent optoelectronic properties. In the field of ...

Abstract: It is well known that inclined sidewall scattering structures can improve the light extraction efficiency (LEE) of micro deep ultraviolet (DUV) light-emitting diodes (LEDs). However, ...

Organic LEDs are light emitting diodes (LEDs) that use polymers or small organic molecules as their optically active element. Development of organic LEDs is driven in particular by its potential as a ...

There's a lot of confusion surrounding the law for bike lights: is a flashing light legal or does it have to be steady? And do you have to fit reflectors, too? Here, we set the facts straight. It's ...
