Sumitomo has shown a prototype of a car (a Toyota - shown in picture) that uses special type of engine, a liquid-nitrogen cooled one. The use of liquid nitrogen makes usual copper conductors have superconducting properties.
Researchers from the Bar-Ilan University in Israel, collaborating with the Brookhaven National Laboratory in the U.S. have designed superconducting thin films patterned with large arrays of nanowires and loops. The temperature at which they superconduct is pretty low and hard to get for the moment - only 30 °K (-243°C). Magnetic fields have proved themselves to change the material's electrical resistance in an unexpected manner.
Rice University scientists conducted a study on superconductivity. Physicists Pengcheng Dai and Andriy Nevidimoskyy, with some of their colleagues, used simulations and neutron scattering experiments that show that the atomic structure of materials to reveal tiny distortions of the crystal lattice in a so-called iron pnictide compound of sodium, iron, nickel, and arsenic.
New Mexico may become a hub for this kind of energetic interaction, as Clovis is wanted to host the SuperStation, a hub using superconducting cables to link three networks: The Eastern Interconnection, The Western Interconnection and the Texas Interconnection. The 5GW carrying cables will be cooled down to -300°F and thus energy losses through heat will be infinitesimally close to zero.
Dr. Ken Shih and some of his physicist colleagues, have reported the development of the thinnest superconducting metal layer ever created, a superconducting sheet of lead only two atoms thick.
Mexican researchers developed a superconducting ink, containing nano particles, which can boost the efficiency of solar water heaters by as much as seventy percent. Solar...
Researchers from the National Institute of Standards and Technology (NIST) has discovered a new type of iron-based superconductor that shares the same magnetic properties with the older copper-oxide superconductors. The amazing fact is that the new superconductors have all those magnetic properties at higher temperatures.
Since their discovery in late 1980s, superconductors were thought to revolutionize everything that had an electric current flowing, but allowing it to pass through more easily, and with much less heat produced. Ultra-efficient magnetic trains had been envisioned, then, but ...
Following the dream of realizing a high-temperature superconductor, Cornell University researchers just found something about iron-based materials: they can be made to resemble electronic liquid crystals.
One of the great limitations in any electrical or electronic system is resistance. Electrical resistance, measured in “Ω” or ohms, is not a constant,...
