Superconductors to get a low temperature boost (-180°C) from Laser-based refrigerator

University of New Mexico researchers have surpassed themselves in a laser-based cooling project. Professor Mansoor Sheik-Bahae (et al.) and other researchers from the University of Pisa, Italy and the Los Alamos Institute created the world's first all-solid-state cryocooler, that can be used from cooling infrared sensors to superconductors.

Scientists Explain Limitations of High Temperature Superconductors in High Currents

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 ...

Scientists Discover Nano-Scale Superconducting Material

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.

Solar Cells and Supercapacitors Improved by New 3D Germanium Sulfide Nanostructure

Next-generation supercapacitors and solar cells could be improved by a newly-created germanium sulfide (GeS) nanomaterial resembling a shish-kebab. North Carolina State University researchers put up...

Germanium Hydride to Become High Temperature Viable Superconductor

The evolution of energy storage is not enough if we don't also evolve the energy transportation methods. That's why superconductors are not only good for us, but are also necessary in some applications where heat and energy loss, in general, have no place.

New Material Promises Fast Energy Saving Electronics

Scientists developed a new one-atom thick material that allows fast movement of electrical charges. It can boost performance of electronics, while saving power. Scientists from...

Superconductivity Could Be Reinvented

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.

Room Temperature Superconductors: a Step Away

Imagine your television set working for 0.0001Watt, or your electric car charged by the Sun as you go. Imagine almost never ending batteries powering cool engines, no power lost through heat.
