Researchers from the U.S., Russia, and China have bent the rules of classical chemistry and synthesized a "forbidden" compound of cerium and hydrogen -- CeH9 -- which exhibits superconductivity at a relatively low pressure of 1 million atmospheres. Superconductors are materials capable of conducting more
In modern synchrotron sources and free-electron lasers, superconducting radio-frequency cavity resonators are able to supply electron bunches with extremely high energy. These resonators are currently constructed of pure niobium. Now an international collaboration has investigated the potential adva more
University of Chicago scientists are part of an international research team that has discovered superconductivity--the ability to conduct electricity perfectly--at the highest temperatures ever recorded. Using advanced technology at UChicago-affiliated Argonne National Laboratory, the team studied a more
Andy takes a closer look at one of his favourite demos from the 2012 Christmas Lectures, bringing together a levitating superconductor and a bewildering Möbius strip made from over 2,000 magnets. more
Brookhaven Lab physicist Ivan Bozovic explains why a copper-oxide compound can conduct electricity without resistance at temperatures well above those required by conventional superconductors. more
Iron tetraboride (FeB4) are attracting increasing attention due to their attractive electronic and mechanical properties (e.g., superconductivity and superhard). Using particle swarm optimization (PSO) combined with first-principles calculations, we systemically studied the structural phase and prop more
Charles Pence Slichter died on February 19 of this year at the age of 94. Charlie, as he was known to his friends, was one of the giants of postwar physics, a pioneer of electron and nuclear magnetic resonance (NMR), and a renowned expert on superconductivity, a remarkably influential educator, and more
Two-dimensional (2D) boron has been predicted to show superconductivity. However, intrinsic 2D carbon and phosphorus have not been reported to be superconductors, which has inspired us to study the superconductivity of their mixture. Here we performed first-principles calculations for the electronic more
Superconductivity levitating above a high-temperature superconductor , cooled with liquid nitrogen . Persistent electric current flows on the surface of the superconductor, acting to exclude the magnetic field of the magnet (the Meissner effect ... more
