(Phys.org)—Scientists have discovered that a solar cell consisting of two or three layers of quantum dots, with each layer tuned to a different part of the solar spectrum, has an efficiency that is 40-60% higher than the ...
(PhysOrg.com) -- Conventional lenses can resolve structures around 200 nanometers (nm) in size, but scientists in Europe have for the first time developed a lens capable of achieving optical resolution of under 100 nm at ...
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.
