Graduate student Peter Yunker sheds light on the mystery of aging glass.Priya Ratneshwar
Glasses have been used for thousands of years, but some of the fundamental properties of these common household and industrial materials still remain unexplained. One such puzzle is why glasses become more viscous and rigid over time without major changes to their structure—a phenomenon known as aging. A new study conducted by physics doctoral student Peter Yunker, James M.
