The new metamaterial is made by stacking silver and silicon nitride nanolayers. It may find applications in novel optical components or circuits and the design of more efficient leds. The work will appear on October 13th in Nature Photonics.
Physicists have solved a mystery that has puzzled scientists for half a century. They show with the help of powerful microscopes that the distance between graphite oxide layers gradually increases when water molecules are added.
Researchers have detected the smallest force ever measured -- approximately 42 yoctonewtons -- using a unique optical trapping system that provides ultracold atoms. A yoctonewton is one septillionth of a newton.
Unique groups of microorganisms capable of converting hazardous chlorinated chemicals like trichloroetheene into ethene, a benign end product of microbial biodegradation, have been examined by scientists.
Drawing inspiration from the structure of bones and bamboo, researchers have found that by gradually changing the internal structure of metals they can make stronger, tougher materials that can be customized for a wide variety of applications --...
Physicists say they have unlocked one key mystery surrounding high-temperature superconductivity. Their research found a remarkable phenomenon in copper-oxide (cuprate) high-temperature superconductors.
Scientists have developed a rechargeable battery that is all organic and could be scaled up easily for use in power plants where it can make the energy grid more resilient and efficient by creating a large-scale means to store energy for use as...
Turning the "hydrogen economy" concept into a reality, even on a small scale, has been a bumpy road, but scientists are developing a novel way to store hydrogen to smooth out the long-awaited transition away from fossil fuels.
Scientists have found that two-dimensional (2-D) nanostructures with asymmetric design enable a new quantum mechanism, triggering the emission of tunable light at terahertz frequencies-with unprecedented efficiency.
