Latest Levitation Stories
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 spectroscopy.
Material could be evidence of a new phase of matter debated by physicists; properties could be harnessed for future superconductors, computer electronics.
A new material with a split personality -- part superconductor, part metal -- has been observed by a Princeton University-led research team.
The Key Laboratory of Applied Superconductivity, Institute of Electrical Engineering, Chinese Academy of Sciences, Beijing, and China Research have collaborated to reveal the heat treatment effects on the superconducting properties of Ag-doped Sr0.6K0.4Fe2As2 compounds.
Superconducting materials, which transmit power resistance-free, are found to perform optimally when high- and low-charge density varies on the nanoscale level.
Scientists have been trying for some 20 years to understand why the low temperature at which copper-oxide superconductors carry current with no resistance can't be increased to be closer to room temperature.
Scientists are reporting development of a new use for magnetic levitation, or "maglev," the futuristic technology best known for enabling high-speed passenger trains to float above the tracks.
What could be better than diamond when it comes to a superhard material for electronics under extreme thermal and pressure conditions?
Materialâ€™s fluctuating response to a magnetic field could lead to switchable superconducting wires.
New images of iron-based superconductors are providing telltale clues to the origin of superconductivity in a class of ceramic materials known as pnictides.
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...
- In Roman antiquity, the return of a person who had been banished, or taken prisoner by an enemy, to his old condition and former privileges.
- In international law, that right by virtue of which persons and things taken by an enemy in war are restored to their former status when coming again under the power of the nation to which they belonged.
