Paul C.W. Chu is science's version of a champion pole vaulter. Every time he smashes a world record, he just puts the bar a bit higher and goes at it again. It's not just that he's never satisfied with himself; he also knows his many competitors won't let the record stand. What Chu, a University of Houston physicist, and his rivals keep pushing higher and higher is the temperature at % which it's possible to create superconductors --those almost magical materials that allow electricity to flow through them with no resistance whatsoever. When scientists...
...Chu and his colleagues first stunned the research community six years ago by showing that a compound containing the exotic element yttrium could become a superconductor at 98 degrees on the Kelvin scale favored by physicists (that's a not-so-balmy -283 degreesF). That record, broken repeatedly, is now as outdated as the 19-foot pole vault, and last month the contest heated up again. First Chu announced in the journal Nature that a mercury-based compound could superconduct at 153 degreesK (-184 degreesF), a startling 20 degrees higher than the old standard. He got that result by subjecting...
...around 4 degreesK) through the use of liquid helium, an expensive and hard-to-handle coolant. The goal of current research is to produce superconductors that can perform their magic at less frigid temperatures that are easier to reach and maintain. What's exciting about the latest mercury compounds, Chu points out, is that they can theoretically do their thing with the help of ordinary coolants like Freon, which circulates in household refrigerators...
