Currents in mercury superconductors.The addition of mercury to copper oxide Noun 1. copper oxide - an oxide of copper oxide - any compound of oxygen with another element or a radical superconductors has allowed researchers to create materials that lose all resistance to the flow of electric current at temperatures as high as 130 kelvins (-143 degrees C). Now, Arunava Gupta Gupta (g  p`tə), Indian dynasty, A.D. c.320–c.550, whose empire at its height encompassed much of N India. Ancient Indian culture reached a high point during this period. and his colleagues at the IBM (International Business Machines Corporation, Armonk, NY, www.ibm.com) The world's largest computer company. IBM's product lines include the S/390 mainframes (zSeries), AS/400 midrange business systems (iSeries), RS/6000 workstations and servers (pSeries), Intel-based servers (xSeries) Thomas J. Watson Research Center The Thomas J. Watson Research Center is the headquarters for the IBM Research Division.The center is on three sites, with the main laboratory in Yorktown Heights, New York, 45 miles north of New York City, a building in Hawthorne, New York, and offices in Cambridge, in Yorktown Heights, N.Y., have produced thin films of these superconductors capable of sustaining current densities at least 10 times greater than those possible in bismuth- or thallium-based copper oxide superconductors. |
