Hopping atoms help predict how liquid silica cools into good glass

Despite millennia of glass making, the physics of what happens when silica sand is melted and cooled is still something of a mystery to researchers. Now, in a groundbreaking window into what happens on a molecular level as liquid silica cools into glass, researchers at the University of Wisconsin-Madison have used sophisticated computational techniques to create a compelling model of how and why flow behaviors change during the glass-cooling process.

The study was led by Bu Wang, an assistant professor of civil and environmental engineering and materials science and engineering at UW-Madison, and Zheng Yu, a PhD student in materials science and engineering. It appears in the July 2022 issue of the journal Physical Review Letters.
