In one scene, she pretended to be talking to another extra while passing behind the movie's star Keanu Reeves. She also played one of the workers fleeing the lab before it exploded. Among the extras were people just waiting for their big break, as well as others from all walks of life including bankers, lawyers and jewelers, to name a few. When the two long days were finished, Benson, said, crew members asked the tired and bedraggled extras if they'd be willing to work again when they return to the area in April. For the organic superconductor group of the Chemistry and Materials Science divisions , this means becoming a testbed for a pair of industry's latest research instruments.
Magnetic studies are one way to determine if a material is a superconductor.
Previously, the best equipment available worked at 4.15 K and 10,000 Gauss. In the last 18 months, his group has discovered 21 ambient-pressure organic superconductors, nearly doubling the number of such materials known. Siemens recognized Argonne as a center of excellence in X-ray diffraction. A beam of X-rays is focused on a crystal, and the beam scatters from the specimen's atoms, forming a pattern of dots. By analyzing the pattern, scientists can deduce the atomic structure of the sample.
