In still other applications, the intense magnetic fields that might someday be generated by the new superconductors should benefit any device that now uses electromagnetism in its operation -- medical diagnostic imaging machines, magnetically levitated trains, fusion-energy generators -- and will undoubtedly spawn a host of new machines. Electric motors could...
From the time that Dutch Physicist Heike Kamerlingh Onnes discovered superconductivity in 1911 until the recent rash of breakthroughs, there was only one way to produce the phenomenon: by bathing the appropriate metals -- and later, certain metallic alloys -- in liquid helium. This exotic substance is produced by lowering the temperature...
In medicine, superconducting magnets are at the heart of magnetic resonance- imaging machines. The magnets' powerful fields first align the atoms of the body. Then a pulse of radio waves knocks them momentarily out of alignment. When the atoms return to their previous attitudes, they emit radiation that produces detailed...
University of Iowa Radio Astronomer Robert Mutel is spearheading a drive to fly advanced imaging equipment to seven observatories in the southern hemisphere that lack the sophisticated instruments. Mutel already has several offers from groups around the world to lend some of their own equipment. Indeed, his group has already...
Not so. Wu's group, under the direction of University of Houston Physicist Paul C.W. Chu, had achieved the phenomenon of superconductivity at a higher temperature than ever before. And the National Science Foundation announced last week that Chu's Houston lab had pushed that temperature 5 degrees higher -- to...
