A new way of harnessing photons for electricity, potential for capturing a wider spectrum of solar energy
The quest to harness a broader spectrum of sunlight's energy to produce electricity has taken a radically new turn, with the proposal of a "solar energy funnel" that takes advantage of materials under elastic ...
Engineers' new metamaterial doubles up on invisibility (w/ Video)
(Phys.org) —The new material's artificial "atoms" are designed to work with a broad range of light frequencies. With adjustments, the researchers believe it could lead to perfect microscope lenses or invisibility ...
New laser shows what substances are made of, could be new eyes for military (w/ video)
A new laser that can show what objects are made of could help military aircraft identify hidden dangers such as weapons arsenals far below.
Moth-inspired nanostructures take the color out of thin films
Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film ...
Scientists measure near-field behavior of semiconductor plasmonic microparticles
(Phys.org) —Recent progress in the engineering of plasmonic structures has enabled new kinds of nanometer-scale optoelectronic devices as well as high-resolution optical sensing. But until now, there has ...
First entanglement between light and optical atomic coherence
Using clouds of ultra-cold atoms and a pair of lasers operating at optical wavelengths, researchers have reached a quantum network milestone: entangling light with an optical atomic coherence composed of ...
Researchers find world's first x-ray laser produces most coherent x-ray radiation ever
Researchers show short laser pulses selectively heat gold nanoparticles
(Phys.org)—Plasmonic gold nanoparticles make pinpoint heating on demand possible. Now Rice University researchers have found a way to selectively heat diverse nanoparticles that could advance their use ...
Nanobelts support manipulation of light
(PhysOrg.com) -- They look like 2-by-4s, but the materials being created in a Rice University lab are more suited to construction with light.
Electrified graphene a shutter for light
(Phys.org) -- An applied electric voltage can prompt a centimeter-square slice of graphene to change and control the transmission of electromagnetic radiation with wavelengths from the terahertz to the midinfrared.
Research team discovers new way to make near perfect light absorber
New experiment helps explain extraordinary optical transmission
Building chips from collapsing nanopillars
By turning a common problem in chip manufacture into an advantage, MIT researchers produce structures only 30 atoms wide.
Small distant galaxies host supermassive black holes
(PhysOrg.com) -- Using the Hubble Space Telescope to probe the distant universe, astronomers have found supermassive black holes growing in surprisingly small galaxies. The findings suggest that central black ...
