Scientists Explain Limitations of High Temperature Superconductors in High Currents
Posted by Ovidiu in Superconductors on June 28, 2010
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
Posted by Ovidiu in Superconductors on June 15, 2010
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.

Molecular-Level Superconducting Material Discovered by Ohio Scientists
Posted by Ovidiu in Superconductors on April 5, 2010
A sheet less than a nanometer wide and four pairs of molecules now constitutes the world’s smallest superconductor and proves that superconducting nanoscale materials can be made, an obvious advance for nano-scaled electronics and energy applications.

New Research Showing Fabrication Pattern for Higher-Temperature Superconductors
Posted by Ovidiu in Superconductors on March 19, 2010
Researchers from Princeton University, Brookhaven National Laboratory and the Central Research Institute of Electric Power Industry in Japan, using Scanning Tunneling Microscopy, have discovered how in a superconducting material, at a nano-scale level, regions with stronger superconductivity helped regions with weaker superconductivity survive when exposed to higher temperature.

Superconductors to get a low temperature boost (-180°C) from Laser-based refrigerator
Posted by Ovidiu in Superconductors on January 25, 2010
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.

New Discovery Sheds Light on Way to High Temperature Superconductivity
Posted by Ovidiu in Superconductors on November 3, 2009
High temperature superconductors are today what some other time the philosopher’s stone used to be. Research done by Gennady Logvenov and his colleagues from the Brookehaven National Laboratory in Upton, NY sheds a new light on how scientists could engineer materials to obtain their desiderate: room temperature superconductors.

SuperStation: The Superconductor Energy Hub Uniting U.S. Grids
Posted by Ovidiu in Energy news, Superconductors on October 16, 2009
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.
