Real-time spectroscopy is a powerful tool for studying dynamic chemical and physical systems. Unfortunately, conventional spectrometers are relatively slow, and do not permit real-time measurements.
Scientists have discovered an indicator of when re-ionization of the primordial Universe began. The team used the Faint Object Camera and Spectrograph (FOCAS) mounted on the Subaru Telescope to ...
The photovoltaic (PV) cells in traditional solar cells convert sunlight efficiently within a narrow range of wavelengths determined by the material used in the PV cells. This limits their efficiency, ...
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 ...

Wi-Fi and visible light are the same thing, just at different wavelengths
Every wireless router in a home or office broadcasts the same fundamental type of energy that a ceiling light emits. The ...
Curved lenses, like those in cameras or telescopes, are stacked in order to reduce distortions and resolve a clear image. That's why high-power microscopes are so big and telephoto lenses so long.
Using a heat-resistant device, made of tungsten and alumina layers, researchers have found that the device can absorb the sun's broad spectrum radiation and convert it to electricity. The photovoltaic ...
