A small team of chemists, having learned the secrets of light absorption from chlorophylls a and b, can now tune molecules to absorb anywhere in the solar spectrum. They are using this facility to ...

What would Earth look like if it were orbiting a different star? Our very existence is shaped by the amount of light and radiation we receive from the Sun. If Earth were to orbit around a different ...

Several light sources produce light across various wavelengths. While this wavelength spectrum can be useful in lighting applications, other applications require light with a restricted visible ...

Japan is pushing solar hydrogen into a new phase by teaching its materials to drink in colors of sunlight that used to go to waste. Instead of relying only on the most energetic visible wavelengths, ...

UV-Vis spectroscopy is an analytical technique that measures the amount of discrete wavelengths of UV or visible light that are absorbed by or transmitted through a sample in comparison to a reference ...
