Researchers have designed and tested ‘human-centric’ LEDs that emit different wavelengths of blue light depending on whether it’s daytime or nighttime, reducing the disruptive effect artificial light ...

Light-emitting diodes (LEDs) are so ubiquitous that it's easy to forget just how much society relies on these underappreciated technological wonders. Yet, the history of the LED goes back further than ...

BUFFALO, N.Y. — In drug discovery, building complex molecules quickly is the name of the game. Chemists want molecules with increasingly three-dimensional atomic structures because they may be more ...

Call it the fifth generation of light—the availability of electric lights that promote health and well-being by automatically mimicking the natural cycle of light. They switch between blue-rich ...

A research team from the Faculty of Engineering at the University of Hong Kong (HKU) has successfully used mechanical stretching technology to dynamically control the emission color of gallium nitride ...
