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 ...

Geiger-mode avalanche photodiodes (GM-APDs) are highly sensitive light detectors, capable of detecting single photons. Photons of certain wavelengths, when absorbed by photodiodes, generate ...

UV flashlights have everyday uses, but they serve a bigger purpose for law enforcement. Here's how they're often used during ...
