Scientists in Sudan have called for the inclusion of PV module cleaning operations in green building standards to address a key maintenance gap in renewable energy systems.

The device can make what's called an optical frequency comb ... carbon dioxide and methane absorb mid-infrared light efficiently, this wavelength range has been an important tool in monitoring ...

A new study suggests Earth's oceans may have been green during the Archean eon, around 3.8 to 1.8 billion years ago. The greenish hue was due to high iron content and early microbes performing ...

Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in the “useful” mid-infrared wavelength range ... The device ...

Furthermore, the goal of a data-supported evaluation of photodetectors for the near-infrared wavelength range is being pursued. These are used, for example, in material analysis and recycling and ...

The middle (m) photoreceptor response, tuned to green, overlaps with both the long (l) and short (s) photoreceptor responses on either side of the spectrum. There is no wavelength of visible light ...
