Researchers Find Strange New Nano-region Can Form in Quasicrystals Ames, IA (SPX) Feb 21, 2012 A team of international researchers has discovered a new type of structural anomaly, or defect, that can appear in quasicrystals, a unique material with some crystal-like properties but a more complex structure. Pat Thiel, senior chemist at the U.S. Department of Energy's Ames Laboratory, led the international team, which includes scientists from the Institut Jean Lamour at Nancy-Universite in France. In crystals, a "defect" refers to any departure from perfect structural symmetry. While the ... read more |
