Human bodies are not quite as dark as they look. A growing body of research suggests that living tissue constantly releases an ultraweak glow, a stream of photons that appears to switch off when life ...

Physicists at ETH Zurich have developed a lens that can transform infrared light into visible light by halving the wavelength of incident light. The study is published in Advanced Materials. Lenses ...

Chemists have discovered a way to use visible light to synthesize a class of compounds particularly well suited for use in pharmaceuticals. The class of compounds, called azetidines, had been ...

Please provide your email address to receive an email when new articles are posted on . Iron oxide, found in tinted sunscreens, can protect against the visible light spectrum. Bemotrizinol, a highly ...

One way that chemists recycle CO 2 into valuable products is through a process called electrochemical reduction, where a stream of CO 2 gas moves through an electrolysis cell that breaks the CO 2 and ...

A VLC system consisting of a transmitter and a receiver was constructed, and a serializer/deserializer using 8B13B coding was implemented on an FPGA. The data modulated onto the LED light were ...
