A new development from Northwestern University's Manijeh Razeghi could be another tool for protecting our borders.
A type of nanostructure succeeds in increasing the efficiency of electricity-producing photovoltaic cells
Sagrario Domínguez-Fernández, a telecommunications engineer, has managed to increase light absorption in silicon by means of nanostructures etched onto photovoltaic cells. This increases the efficiency obtained in these ...
The realization of photonic chips is a long–sought research goal. Surface plasmon polariton devices and circuits, which bridge the gap between integrated photonics and microelectronic technologies, are promising candidates ...
Climate change can often seem concerned mainly with carbon dioxide and other greenhouse gases far above the Earth—but researchers also want to know what role things on the ground play.
Researchers have developed the first standard LED covering the full visible light, in collaboration with Nichia Corporation.
A revolutionary new type of laser developed by the University of Adelaide is promising major advances in remote sensing of greenhouse gases.
NASA's planet hunter, the Kepler space telescope, has captured the brilliant flash of an exploding star's shock wave—what astronomers call the "shock breakout" of a supernova—for the first time in visible light wavelengths.
New research led by astrophysicists at York University has revealed the fastest winds ever seen at ultraviolet wavelengths near a supermassive black hole.
Researchers from North Carolina State University and the University of Delaware have developed an algorithm that can quickly and accurately reconstruct hyperspectral images using less data. The images are created using instruments ...
