Modeling teaches old dogs new tricks: Viscosity predictions from dilatometry and DSC

By Jonathon Foreman / July 31, 2020

Determining viscosity of a glass through experiment is a slow and expensive process. In two recent papers published in JACerS, Penn State professor John Mauro and his colleagues show how it can be predicted much easier by using dilatometry and DSC to calculate parameters for a glass viscosity model that was proposed in 2009.

Necessary roughness: Engineering particle surfaces to control how cements and other suspended materials flow

By April Gocha / May 4, 2018

Researchers from ETH Zurich have created a library of silicate particles and precisely studied how the surface roughness of particles affects the viscosity and thickening behavior of suspensions of those particles.

Long-term measurements of ultrastable glass flow cut short with new process

By April Gocha / March 4, 2015

Researchers from Universitat Autònoma de Barcelona (Spain), University of Rome La Sapienza (Italy), and Politecnico Milano (Italy) have devised a technique to rapidly manufacture “old” glass—a process that would otherwise take millennia—and have generated results that suggest current glass theories might need revision.
