A spectrometer is a pretty common lab instrument, useful for determining the absorbance of a sample across a spectrum of light. The standard design is simple; a prism or diffraction grating to break ...
US scientists have discovered that using wavelength-selective, semi-transparent PV modules to absorb the blue light spectrum while transmitting red light onto crops can increase crop yield. “Today’s ...
Scientists have developed an ultra-thin, paper-like LED that emits a warm, sunlike glow, promising to revolutionize how we light up our homes, devices, and workplaces. By engineering a balance of red, ...
