Building chips from collapsing nanopillars
By turning a common problem in chip manufacture into an advantage, MIT researchers produce structures only 30 atoms wide.
In a major breakthrough, scientists control light propagation in photonic chips
Researchers at Columbia Engineering School have built optical nanostructures that enable them to engineer the index of refraction and fully control light dispersion. They have shown that it is possible for light (electromagnetic ...
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 ...
Research team develops method to produce large sheets of metamaterials
Hidden physics make fish glitter
A theory borrowed from physics to understand how electrons move in semiconductors may explain the silvery mirror-like appearance of many fish, recent research suggests.
Researchers synthesize material for efficient plasmonic devices in mid-infrared range
A research team led by North Carolina State University has identified and synthesized a material that can be used to create efficient plasmonic devices that respond to light in the mid-infrared (IR) range. This is the first ...
Mission studies the Sun in soft X-rays
At any given moment, our sun emits a range of light waves far more expansive than what our eyes alone can see: from visible light to extreme ultraviolet to soft and hard X-rays. Different wavelengths can ...
Nanodust particles in the interplanetary medium
Dust particles smaller than about a wavelength of light are abundant in our solar system, created by collisions between asteroids and from the evaporation of comets. As they scatter sunlight, these particles ...
SUNRISE offers new insight on sun's atmosphere
Three months after the flight of the solar observatory Sunrise – carried aloft by a NASA scientific balloon in early June 2013—scientists from the Max Planck Institute for Solar System Research in Germany ...
Study gets to the roots of plants' natural sunscreen
(Phys.org) —Plants bask in the sun and need its light to live, but they also coat themselves in a natural sunscreen like a sunbather on the beach, protecting themselves from damaging rays.
Enhancing microalgae growth to boost green energy production
(Phys.org) —A groundbreaking nanoparticle system which stimulates the growth of microalgae – a valuable resource used in the production of biofuels and medical compounds – has been developed by a team ...
Tiny antennas let long light waves see in infrared
(Phys.org) —University of Illinois at Urbana-Champaign researchers have developed arrays of tiny nano-antennas that can enable sensing of molecules that resonate in the infrared (IR) spectrum.
Researchers' smartphone 'microscope' can detect a single virus, nanoparticles
(Phys.org) —Your smartphone now can see what the naked eye cannot: A single virus and bits of material less than one-thousandth of the width of a human hair.
Next-gen e-readers: Improved 'peacock' technology could lock in color for high-res displays
Iridescence, or sheen that shifts color depending on your viewing angle, is pretty in peacock feathers. But it's been a nuisance for engineers trying to mimic the birds' unique color mechanism to make high-resolution, reflective, ...
