Addressing the energy harvesting storage gap—ceramic matrix composites contain corrosive materials in thermal energy storage

By Jonathon Foreman / October 2, 2020

Thermal energy storage technologies are one way to store energy generated from renewable sources. But producing materials that can contain the high-temperature and corrosive materials integral to this technology is an ongoing area of research. Two recent ACerS journal articles explore methods of fabricating C/C-SiC CMCs for use as container materials.

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.
