Searching for the Perfect Glass


 

HPCAT experiments by scientists from Carnegie, George Mason University, Zhejiang University, and Stanford University, reveal the possibility of creating a metallic glass that is organized on a larger scale. They have discovered glasses that demonstrate order among the nearest neighboring atoms, called short-range order, and a slightly wider range of atoms, called medium-range order. Most research about finding or creating a glass with a long-range, nearly crystalline, level of order - referred to as the perfect glass state - has been conducted on ice and the minerals silica and zeolite. Until now, however, no research into long-range order glass has been successful. Their results have been published in Science. (more…)
