Australian scientists are developing a "reverse solar" panel—a thermoradiative diode that converts the Earth's emitted ...

It's got an incredibly bright OLED screen with performance that will keep you from using it for much else than work.

It produces only a little power, but its innovative approach could support hardware that operates during lengthy periods of total darkness, such as deep-space satellites.

Stretchable displays that can bend and twist like skin have long been a dream of engineers working on wearable electronics.

Scientists have shown that twisting a crystal at the nanoscale can turn it into a tiny, reversible diode, hinting at a new era of shape-engineered electronics.

Scientists have developed a way to generate tiny amounts of solar energy at night. It’s true potential could be in space.

2 years ago, you could only turn to 1 manufacturer if you were looking to buy a laser weeder. Today, there are at least 8 and ...

Ultraviolet-B (UV-B) semiconductor lasers are highly sought for medical, biotechnology, and precision manufacturing applications; however, previous UV-B laser diodes were limited to pulsed operation ...

Abstract: Near-infrared Single Photon Avalanche Diodes (SPADs) are the dominant, practical single photon detectors for quantum applications and low-level optical sensing. Although some infrared SPADs ...

A diode is a tiny component that controls the flow of electricity by allowing current to pass in only one direction. This video explains how diodes work, what makes them unique, and why they’re used ...

The 9-ft. bowl-shaped antenna pointed straight up. Above it floated an object that looked for all the world like a small, square bedspring with a tiny helicopter attached. The rotor blades whirled ...
