Ever since Mohammed Ali Hamadei was arrested at Frankfurt airport last January after bottles of liquid explosive were found in his luggage, the West German government had been in a quandary. At first there was hope that the Lebanese terrorist suspect would be extradited to the U.S., where he and three others are wanted for the 1985 hijacking of a TWA jetliner from Athens to Beirut and the murder of a passenger, U.S. Navy Diver Robert Stethem. But when two West Germans were kidnaped in Beirut a few days after Hamadei's arrest, the government began temporizing. Last week, despite...
Ramey's silken voice, which ranges high into traditional baritone territory, is worlds apart from the toneless barking and roaring that too often pass for singing among basses. A flexible, liquid instrument, it can scale the trickiest Rossini coloratura passages or rattle the rafters in triumph...
...smaller scale, superconductors have already been used to create superfast electronic switches called Josephson junctions (after Nobel Laureate Brian Josephson, the British physicist who discovered the principle on which they are based), which until now could operate only at liquid-helium temperatures. For both technical and economic reasons, IBM abandoned its Josephson junction project in 1983. But IBM Physicist Sadeg Faris quit the company, obtained licenses for the technology and formed Hypres, Inc., which has begun marketing its first Josephson junction product -- a high-speed oscilloscope. Says Faris: "The new materials are at a primitive stage, but we're anxious...
...current pushes against the field of the magnet, the ship moves forward. Saji has already moved up his timetable and hopes to complete a 100-ton "magship" within four years. "Thanks to the new materials," he says, "magnets will be lighter and easier to handle. Once we can replace liquid helium with liquid nitrogen, the whole process of outfitting the ship will be simplified. It's a fantastic development...
...planning the train, Japanese engineers chose superconducting magnets ( because for a given input of electricity they generate more intense magnetic fields -- and thus greater lifting and propulsion power -- than conventional electromagnets. The drawback: the liquid-helium coolant needed for the superconducting magnets is expensive, and a heavy compressor is required in each coach to reliquefy the evaporating helium. That is why maglev engineers are excited by the idea of the new high-temperature superconductors, which would use considerably less expensive liquid nitrogen as a coolant and require far smaller compressors. The developments of the past few months, says Research Chief...
