This engineer doesn’t use nail polish, but his wife does. And he deals with plenty of PCBs. What do these things have in ...

As COVID-19 continues to ravage global populations, the world is singularly focused on finding ways to battle the novel coronavirus. That includes UC Santa Barbara’s Solid State Lighting & Energy ...

Ultraviolet light occurs between the visible and x‐ray spectrums. The Ultraviolet wavelength range is specified as 10 nm to 400 nm; however, many optoelectronic companies also consider wavelengths as ...

Even though we're warned about the harmful effects of the ultraviolet (UV) rays in sunlight, they're essential for the production of vitamin D in the body. Now, scientists are claiming that UV LEDs ...

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 ...

Scientists demonstrate the first direct germicidal effect with an ultraviolet LED source. A US collaboration has reduced levels of E.coli. bacteria in water by over five orders of magnitude using 280 ...

An international team of researchers has, for the first time, comprehensively assessed the state of the art of commercial UVC LEDs and summarized the findings in an open-access review. These compact, ...

While a trip to the nail salon can be quite the treat, bi-monthly visits are often time-consuming and expensive. A simple way to save without giving up on the joy that is experimenting with cherry ...

UV light inactivates germs in drinking water. Until now, this disinfection process has typically relied on mercury-vapor lamps, which emit light in the UV spectrum. However, mercury is a toxic heavy ...

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 ...
