Traditional solar cells harvest only a narrow sliver of the electromagnetic energy pouring down onto Earth, and that's one of the reasons it's been so challenging to get solar efficiency beyond 20-30 ...

Ultraviolet light has always sat at the edge of human perception, powerful yet invisible, more associated with sterilizing ...

It is remarkable that Raman spectra can, with the help of statistical inference, be used to predict cellular physiology and proteome composition. By making this possible, the work of Kamei et al. has ...

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 ...

Telescope mirror coatings (e.g., silver, gold, aluminum) determine which wavelengths of light are reflected. X-ray telescopes use specially shaped mirrors to reflect X-rays, which are normally ...

How can we measure visible light? The electromagnetic spectrum includes all forms of light energy, known as electromagnetic radiation. (1) Different types of electromagnetic radiation such as radio ...

Multi-wavelength femtosecond pulses with flexible tunability in both temporal and spectral domain have been widely desired owing to their potential applications in controlling strong field ionization, ...

Japan is pushing solar hydrogen into a new phase by teaching its materials to drink in colors of sunlight that used to go to ...

Did you know that the world around us is filled with different types of light waves ? From the warm glow of the sun to audible radio waves and invisible gamma rays, electromagnetic waves (action ...
