(PhysOrg.com) -- Scientists at the U.S. Department of Energy's Argonne National Laboratory have discovered the microscopic mechanism behind the phenomenon of superinsulation, the ability of certain materials to completely block the flow of electric current at low temperatures. The essence of the mechanism is what the authors termed "multi-stage energy relaxation." http://www.physorg.com/news180035393.html Physics Mon, 14 Dec 2009 18:40:02 EST news180035393 Physicists at the National Institute of Standards and Technology have demonstrated the first "universal" programmable quantum informationprocessor able to run any program allowed by quantum mechanics -- the rules governing the submicroscopic world -- using two quantum bits (qubits) of information. The processor could be a module in a future quantum computer, which theoretically could solve some important problems that are intractable today. http://www.physorg.com/news177515046.html Physics Sun, 15 Nov 2009 13:45:25 EST news177515046 (PhysOrg.com) -- Physicists at Harvard University have created a quantum gas microscope that can be used to observe single atoms at temperatures so low the particles follow the rules of quantum mechanics, behaving in bizarre ways. http://www.physorg.com/news176569616.html Physics Wed, 04 Nov 2009 15:07:42 EST news176569616 (PhysOrg.com) -- Using precision techniques for making superconducting thin films layer-by-layer, physicists at the U.S. Department of Energy's Brookhaven National Laboratory have identified a single layer responsible for one such material's ability to become superconducting, i.e., carry electrical current with no energy loss. The technique, described in the October 30, 2009, issue of Science, could be used to engineer ultrathin films with "tunable" superconductivity for higher-efficiency electronic devices. http://www.physorg.com/news176045082.html Physics Thu, 29 Oct 2009 14:25:20 EST news176045082 (PhysOrg.com) -- A PhD student from the London Centre for Nanotechnology has won a prize for solving a decade-long mystery central to understanding modern magnetic systems. http://www.physorg.com/news175857283.html Physics Tue, 27 Oct 2009 10:15:30 EST news175857283 Rutgers researchers have discovered novel electronic properties in two-dimensional sheets of carbon atoms called graphene that could one day be the heart of speedy and powerful electronic devices. http://www.physorg.com/news174745964.html Nanotechnology Wed, 14 Oct 2009 13:33:58 EST news174745964 (PhysOrg.com) -- The Applied Superconductivity Center at the National High Magnetic Field Laboratory has received $1.2 million in funding from the U.S. Department of Energy to understand and enhance a new form of superconducting material that could be used to build more-powerful magnets used in a wide range of scientific research. http://www.physorg.com/news174676669.html Physics Tue, 13 Oct 2009 23:20:01 EST news174676669 (PhysOrg.com) -- From detailed assessments of electronic structure, researchers at the University at Buffalo, Cornell University, Stony Brook University and Moscow State University discovered that unexpected hydrides violating standard valence rules, such as LiH6 and LiH8, become stable metals at a pressure approximately one quarter of that required to metalize pure hydrogen itself; findings that were published in an October 5, 2009 early edition of the Proceedings of the National Academy of Sciences. http://www.physorg.com/news174564247.html Physics Mon, 12 Oct 2009 11:04:31 EST news174564247 (PhysOrg.com) -- A team led by physicists at the Science and Technology Facilities Council (STFC) and Brookhaven National Laboratory (BNL) have resolved a decade-long puzzle that is set to have huge implications for use of one of the most versatile classes of materials available to us for future technology applications: copper oxide ceramics.

This confirms that certain conditions necessary for superconductivity exist at the warmer temperatures that would make these materials practical for energy-saving applications - if scientists can figure out how to get the current flowing. http://www.physorg.com/news170602115.html Physics Thu, 27 Aug 2009 14:29:39 EST news170602115
