Title: Relaxation is Everywhere


As a nonequilibrium material, glass is continually relaxing towards its metastable supercooled liquid state. A comprehensive understanding of glass relaxation is of critical importance for many high-tech applications of glass, including optical fiber, glass substrates for liquid crystal displays, and chemically strengthened cover glass for electronic devices.

In this presentation, Dr. Mauro will review the current state-of-the-art in understanding the dynamics of glass relaxation, including the physical origins of its non-Arrhenius and non-exponential characters. 


John C. Mauro is professor and associate head for graduate edcuation in the Department of Materials Science and Engineering at The Pennsylvania State University. He earned a B.S. in Glass Engineering Science (2001), B.A. in Computer Science (2001), and Ph.D. in Glass Science (2006), all from Alfred University. He joined Corning Incorporated in 1999 and served in multiple roles there, including Senior Research Manager ofthe Glass Research department, where he led a group of15 scientists and technicians in the development ofnew glass and glass-ceramic products. John joined the faculty at Penn State in 2017 and is currently a world-recognized expert in fundamental and applied glass science, statistical mechanics, computational and condensed matter physics, thermodynamics, and the topology ofdisordered networks.

John is the inventor or co-inventor ofseveral new glass compositions for Corning, including Coming Gorilla® Glass products. John is a pioneer in the use ofphysics-based and machine learning models for the design ofnew glassy materials. He is the inventor ofnew models for supercooled liquid and glass viscosity, glass structure and topology, relaxation behavior, and thermal and mechanical properties. He is co-author ofFundamentals ofInorganic Glasses, 3rd ed. (Elsevier, 2019), the definitive textbook on glass science and technology. John is also author ofthe forthcoming textbook, Materials Kinetics, to be published by Elsevier in 2021.

John was awarded the N.J. Kreidl Award (2006) from the American Ceramic Society, Glass and Optical Materials Division. In 2010, Penn State University and the International Commission on Glass (ICG) awarded John the W.A. Weyl International Glass Science Award. In 2011, John received the V. Gottardi Prize from the ICG, and in 2012 he was selected as the inaugural recipient ofthe Sir Alastair Pilkington Award from the Society ofGlass Technology. In 2013, John was awarded the S. Donald Stookey Award for Exploratory Research from Coming Incorporated. In 2015, John became a Fellow ofthe American Ceramic Society and was recipient ofthe R.M. Fulrath Award. In the same year, he was also awarded the W.H. Zachariasen Award from the Journal ofNon-Crystalline Solids. In 2016, the National Institute of Ceramic Engineers (NICE) selected John as winner ofthe Karl Schwartzwalder Professional Achievement in Ceramic Engineering (PACE) Award. John is also winner ofComing's Ethnically Diverse Group ofEmployees (EDGE) Excellence Award (2016) for promoting diversity at Coming.

Most recently, John was elected as a Fellow ofthe Society ofGlass Technology (2019) and is recipient of the Faculty ofthe Year Award (2019) at Penn State Materials Science and Engineering. John is the author ofmore than 275 peer-reviewed publications and has given over 300 presentations at international conferences and seminars. His publications have been cited over 10,000 times, with an index of47. John has 53 granted U.S. patents and ~25 additional patents pending. John is Editor ofthe Journal ofthe American Ceramic Society and Associate Editor ofthe International Journal ofApplied Glass Science. He also serves as an Editorial Board member for the Journal ofNon-Crystalline Solids and was a Volume Organizer for MRS Bulletin.
