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. In ACS' bi-weekly Journal of Agricultural and Food Chemistry, they describe putting maglev to use in an inexpensive sensor for analyzing food, water, and other beverages. George Whitesides and colleagues note that measurements of a substance's density are important in the food industry, health care, and...

What could be better than diamond when it comes to a superhard material for electronics under extreme thermal and pressure conditions? Quite possibly BC5, a diamond-like material with an extremely high boron content that offers exceptional hardness and resistance to fracture, but unlike diamond, it is a superconductor rather than an insulator. A research team in China studying BC5 describes its potential in the Journal of Applied Physics, which is published by the American Institute of...

Material's fluctuating response to a magnetic field could lead to switchable superconducting wires A team of scientists from Bar-Ilan University, Israel, and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory has fabricated thin films patterned with large arrays of nanowires and loops that are superconducting "” able to carry electric current with no resistance "” when cooled below about 30 kelvin (-243 degrees Celsius). Even more interesting, the scientists...

New images of iron-based superconductors are providing telltale clues to the origin of superconductivity in a class of ceramic materials known as pnictides. The images reveal that electrons responsible for the superconducting currents in some pnictides tend to flow primarily along the boundaries between the crystal grains that make up the superconductors. The research, which is reported in a pair of papers appearing in the current issue of the journal Physical Review B, may help physicists to...

Researchers at Universitat Autònoma de Barcelona, ICMAB-CSIC, and the firms Labein Tecnalia and Nexans, coordinated by the electrical company Endesa, have constructed a 30m cable and the terminals needed to connect it to the network using the high-temperature superconducting material BSCCO. This is the most advanced cable in terms of distribution (24 kV), since its current value is higher than that obtained up to date, 3200 Amperes RMS, and therefore can transport the...

Study paves way for development of nanocircuits for energy, electronics applications Scientists have discovered the world's smallest superconductor, a sheet of four pairs of molecules less than one nanometer wide. The Ohio University-led study, published today as an advance online publication in the journal Nature Nanotechnology, provides the first evidence that nanoscale molecular superconducting wires can be fabricated, which could be used for nanoscale electronic devices and energy...

Controlling structure on the nanoscale could lead to better superconductors Superconductors, materials in which current flows without resistance, have tantalizing applications. But even the highest-temperature superconductors require extreme cooling before the effect kicks in, so researchers want to know when and how superconductivity comes about in order to coax it into existence at room temperature. Now a team has shown that, in a copper-based superconductor, tiny areas of weak...

Brown University physicist Vesna Mitrovic and colleagues at Brown and in France have discovered magnetic waves that fluctuate when exposed to certain conditions in a superconducting material. The discovery may help scientists understand more fully the relationship between magnetism and superconductivity at the quantum level. Results are published in Physical Review Letters. At the quantum level, the forces of magnetism and superconductivity exist in an uneasy relationship. Superconducting...

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...
