Technique reveals quantum phase transition; could lead to superconducting transistors for power-saving electronics Like atomic-level bricklayers, researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are using a precise atom-by-atom layering technique to fabricate an ultrathin transistor-like field effect device to study the conditions that turn insulating materials into high-temperature superconductors. The technical break-through, which is described in the...

Researchers discover a rare physical phenomenon at low temperatures and high magnetic fields Just in time for the 100th anniversary to commemorate the discovery of superconductivity by the Dutch physicist Heike Kamerlingh Onnes on April 8, 1911, scientists from the Helmholtz-Zentrum Dresden-Rossendorf and the TU Dresden published their research results in the journal Physical Review B. Headed by Dr. Thomas Herrmannsdörfer, the team from the HZDR's High Magnetic Field Laboratory (HLD)...

ZURICH, April 18, 2011 /PRNewswire/ -- Twenty-five years ago IBM (NYSE: IBM) scientists, J. Georg Bednorz and K. Alex Muller altered the landscape of physics when they observed superconductivity in an oxide material at a temperature 50 percent higher(1), (-238 deg C, -397 deg F) than what was previously known. This discovery opened an entirely new chapter in the field of physics and earned them the Nobel Prize for Physics in 1987. (Photo:...

On April 8, 2011, the scientific community will celebrate the centennial of the discovery of superconductivity"”the ability of certain materials to conduct electricity without resistance when cooled below a specific temperature. Quantum voltage standards are among the successful practical applications of superconductivity, so to mark the anniversary, the National Institute of Standards and Technology (NIST) has created an online museum highlighting important accomplishments and...

Scientists have found the strongest evidence yet that a puzzling gap in the electronic structures of some high-temperature superconductors could indicate a new phase of matter. Understanding this "pseudogap" has been a 20-year quest for researchers who are trying to control and improve these breakthrough materials, with the ultimate goal of finding superconductors that operate at room temperature."Our findings point to management and control of this other phase as the correct path toward...

Japanese researchers have been immersing iron-based compounds in hot alcoholic beverages such as red wine, sake and shochu to induce superconductivity. Scientists from the National Institute for Materials Science, Japan, found that immersing pellets of an iron-based compound in heated alcoholic beverages for 24 hours greatly increase their superconducting ability. Iron-based compounds usually become superconductive after being exposed to air. This process however can take up to several...

A researcher at the National Institute of Standards and Technology (NIST) has invented a method of making high-temperature superconducting (HTS) cables that are thinner and more flexible than demonstration HTS cables now installed in the electric power grid while carrying the same or more current. The compact cables could be used in the electric grid as well as scientific and medical equipment and may enable HTS power transmission for military applications. Described in a paper just published...

Illinois researchers have documented the first observations of some unusual physics when two prominent electric materials are connected: superconductors and graphene. Led by University of Illinois physics professor Nadya Mason, the group published its findings in the journal Nature Physics. When a current is applied to a normal conductor, such as metal or graphene, it flows through the material as a stream of single electrons.  By contrast, electrons travel in pairs in superconductors....

Measurements on super-short timescale indicate loss of coherence among electron pairs and may help explain the mechanism of high-temperature superconductivity As part of an ongoing effort to uncover details of how high-temperature superconductors carry electrical current with no resistance, scientists at Johns Hopkins University and the U.S. Department of Energy's Brookhaven National Laboratory have measured fluctuations in superconductivity across a wide range of temperatures using terahertz...

Material could be evidence of a new phase of matter debated by physicists; properties could be harnessed for future superconductors, computer electronics In 2008, an international team of scientists studying an exotic new superconductor based on the element ytterbium reported that it displays unusual properties that could change how scientists understand and create materials for superconductors and the electronics used in computing and data storage. But a key characteristic that explains the...

Maglev
2014-04-11 09:17:26

Maglev is a vehicle propulsion system that uses magnetic levitation to move a vehicle with magnets instead of wheels. The vehicle hovers a short distance above the guide way by magnets and also uses the magnets for motion. The operation of this system is quite and maintains less friction for improved acceleration and deceleration. Weather does not affect the performance of the vehicle. Currently, some trains make use of the Maglev system, but vacuum tube trains could allow a Maglev system...

An electromagnet, a magnet whose magnetic field is produced by the flow of electric current, works until the electric current ceases. The magnetic field in a simple electromagnet is created by a wire passing through it with an electric current. The strength of the magnet depends on the amount of current. By making the wire into a coil the magnetic field is concentrated. A straight tube coil is a solenoid. A stronger magnetic field can be produced by putting a ferromagnetic material, such as...
