A team of Australian scientists from the University of Technology Sydney (UTS) and the Australian National University (ANU) believe they have developed a way to address a decades-long challenge in the field of quantum materials-the spectral tuning of proposed quantum light sources. [44] A Korean research team has developed a technology to fabricate an ultrathin material for electromagnetic interference (EMI) shielding. [43] As if they were bubbles expanding in a just-opened bottle of champagne, tiny circular regions of magnetism can be rapidly enlarged to provide a precise method of measuring the magnetic properties of nanoparticles. [42] Antennas made of carbon nanotube films are just as efficient as copper for wireless applications, according to researchers at Rice University's Brown School of Engineering. [41] The device is a high-efficiency round-trip light tunnel that squeezes visible light to the very tip of the condenser to interact with molecules locally and send back information that can decipher and visualize the elusive nanoworld. [40] "Smart glass," an energy-efficiency product found in newer windows of cars, buildings and airplanes, slowly changes between transparent and tinted at the flip of a switch. [39] With international collaboration, researchers at Aalto University have now developed a nanosized amplifier to help light signals propagate through microchips. [38] Physicists at the Kastler Brossel Laboratory in Paris have reached a milestone in the combination of cold atoms and nanophotonics. [37] The universal laws governing the dynamics of interacting quantum particles are yet to be fully revealed to the scientific community. [36] Now NIST scientists have designed a vacuum gauge that is small enough to deploy in commonly used vacuum chambers. [35] A novel technique that nudges single atoms to switch places within an atomically thin material could bring scientists another step closer to realizing theoretical physicist Richard Feynman's vision of building tiny machines from the atom up.
