Keywords: Superconductivity (5888575262).jpg NIST researchers have found that new iron-based high-temperature superconductors subtly change their molecular shape as temperatures decrease This graphic shows a superconductor transitioning from tetragonal at top to orthorhombic at about 220 Kelvin -53 Celsius Such physical changes appear to be a precursor to superconductivity in which electric current can flow without resistance Credit NIST Disclaimer Any mention of commercial products within NIST web pages is for information only; it does not imply recommendation or endorsement by NIST Use of NIST Information These World Wide Web pages are provided as a public service by the National Institute of Standards and Technology NIST With the exception of material marked as copyrighted information presented on these pages is considered public information and may be distributed or copied Use of appropriate byline/photo/image credits is requested https //www flickr com/photos/usnistgov/5888575262/ Superconductivity 2008-11-12 13 47 https //www flickr com/people/63059536 N06 National Institute of Standards and Technology PD-USGov National Institute of Standards and Technology https //flickr com/photos/63059536 N06/5888575262 2016-09-07 02 33 35 United States Government Work Uncategorized 2016 December 20 |
