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 ...

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 ...

Spectroscopy, in its broadest sense, is the term given to the investigation and measurement of spectra produced when a substance interacts with or emits electromagnetic radiation. All known matter ...

The relationship between the depth of absorption and the peak wavelength of the deepest absorption for the feature at around 2.7 micrometers in C-type asteroids (shown by the green arrows in figure 2) ...

The applications of ultrathin, conductive films such as those made of graphene have many applications, but it's been thought ...
