Scientists from the Faculty of Physics, University of Warsaw, in collaboration with the University of Oxford and the NIST agency, have shown that quantum interference enables processing of large sets of data faster and more accurately than with standard methods. Their studies may boost applications of quantum technologies in e.g. artificial intelligence, robotics and medical diagnostics. The results of this work have been published in the Science Advances journal.
Researchers at the US Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a graphene device that's thinner than a human hair but has a depth of special traits. It easily switches from a superconducting material that conducts electricity without losing any energy, to an insulator that resists the flow of electric current, and back again to a superconductor -- all with a simple flip of a switch.
Researchers have developed new sensors for measuring acceleration and vibration on trains. The technology could be integrated with artificial intelligence to prevent railway accidents and catastrophic train derailments.
For decades, researchers have chased ways to study biological machines. Every mechanical movement -- from contracting a muscle to replicating DNA -- relies on molecular motors that take near-undetectable steps. Trying to see them move is like trying to watch a soccer game taking place on the moon. Now, with DNA origami helicopters, researchers have captured the first recorded rotational steps of a molecular motor as it moved from one DNA base pair to another.
Carbon materials such as nanotubes, graphene, activated carbon and graphite are in high demand. The research team at Shinshu University set out to create more efficient forms of activated carbon by utilizing the superconducting magnets, thus increasing the volume of pores in the activated carbon by 35%. Many other materials that have negative magnetic susceptibility may also be manufactured using this effective procedure with the superconducting magnets to control for better properties.
Scientists at Linkoping University working with colleagues from China have shown how to achieve efficient perovskite light-emitting diodes (LEDs). In an article published in Nature Communications, they provide guidelines on fabricating high-quality perovskite light emitters, and consequently high-efficiency perovskite LEDs.
Hailed as a pioneer by Photonics Media for his previous discoveries of supercontinuum and Cr tunable lasers, City College of New York Distinguished Professor of Science and Engineering Robert R. Alfano and his research team are claiming another breakthrough with a new super class of photons dubbed 'Majorana photons.' They could lead to enhanced information on quantum-level transition and imaging of the brain and its working.
The quantum logic clock -- perhaps best known for showing you age faster if you stand on a stool -- has climbed back to the leading performance echelons of the world's experimental atomic clocks.
In quasiparticles known as polaritons, states of light and matter are strongly coupled. The group of Prof. Ataç ?mamo?lu at ETH Zurich has now developed a new approach to study nonlinear optical properties of polaritons in strongly correlated electronic states. In doing so, they opened up fresh perspectives for exploring both ingredients of the polariton: novel functionalities for photonic devices and fundamental insight into exotic states of matter.
Rice University engineers use their carbon nanotube films to create a device to recycle waste heat. The device could enhance solar cell output and increase the efficiency of industrial waste-heat recovery.
