Scientists have long known that ultraviolet light can kill pathogens on surfaces and in air and water. UV robots are used to disinfect empty hospital rooms, buses and trains; UV bulbs in HVAC systems ...

Scientists recently determined the optimal ultraviolet-light wavelength for keeping water free of microorganisms. They say that their brand new approach could be used by water treatment plants and ...

A specific wavelength of ultraviolet (UV) light is not only extremely effective at killing the virus which causes COVID-19, but is also safer for use in public spaces, finds new University of Colorado ...

Ultraviolet light has a long history as a disinfectant, and the SARS-CoV-2 virus, which causes COVID-19, is readily rendered harmless by UV light. The question is how best to harness UV light to fight ...

A specific wavelength of ultraviolet (UV) light is not only extremely effective at killing the virus which causes COVID-19, but is also safer for use in public spaces, finds new research. A specific ...

Scientists have developed a fully transparent skin sensor that accurately measures UV radiation, detecting light and ...

To disinfect a surface, you can illuminate it with a blast of ultraviolet (UV) light, which is bluer than the human eye can see. But to specifically inactivate SARS-CoV-2, the virus that causes ...

Asahi Kasei Corporation succeeded in designing a laser diode that emits deep-ultraviolet light. The laser diode emits the world’s shortest lasing wavelength, at 271.8 nanometers (nm), under pulsed ...

US labs NIST and DHS conduct thorough tests to show how different wavelengths interact with virus. To disinfect a surface, you can illuminate it with a blast of ultraviolet light. But to specifically ...

ALBUQUERQUE, N.M. - Researchers at Sandia National Laboratories developing ultraviolet (UV) light-emitting diodes (LEDs) recently demonstrated two deep UV semiconductor optical devices that set ...
