Materials scientists work on the semiconductors that could transform how we disinfect surfaces, spaces, personal protective equipment — even the air we breathe The COVID-19 outbreak brought with it an ...

We are faced with a global epidemic of myopia (short-sightedness) because we are deprived of deep violet light (360-400 nm). Myopia is projected to rise from 23 to 50 percent of the world’s population ...

In a darkened corner of Nanosys's suite here at CES 2025 in Las Vegas was a tiny watch-sized prototype display. At first glance, it didn't seem particularly special. It was bright, for sure, and ...

A recent study has revealed that violet Light-Emitting-Diode (LED) light can significantly reduce browning in fresh-cut apples by enhancing phenolic compounds and suppressing oxidative enzymes. This ...

Researchers have shown that the coronavirus can be killed efficiently, quickly, and cheaply using ultraviolet (UV) light-emitting diodes (UV-LEDs). They believe that the UV-LED technology will soon be ...

Key Takeaways UV lamps require longer curing times and frequent bulb changes. In comparison, LED lamps are faster-curing and ...

Researchers are developing ultraviolet LEDs that have the ability to decontaminate surfaces -- and potentially air and water -- that have come in contact with the SARS-CoV-2 virus. As COVID-19 ...
