Engineered to perfection: The science of chocolate and designing a better chocolate chip

By April Gocha / September 4, 2020

Although chocolate is a simple pleasure for many people around the world, the science behind chocolate as a food and as a material is deliciously complex. Now an industrial designer has re-engineered the chocolate chip to maximize taste and texture, giving it optimal surface area with angular features.

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.

Preparing for hypersonic flight—wing shape affects thermal shock behavior of UHTCs

By Jonathon Foreman / March 27, 2020

Ultrahigh-temperature ceramics are promising materials for protecting aircraft wings from friction during hypersonic flight—but thermal shock can cause these ceramics to crack. In the cover article for the March 2020 International Journal of Ceramic Engineering & Science, researchers in China report how wing shape affects thermal shock behavior of UHTCs.

Two theories, one goal—new formula also describes heat flow in both crystals and glass

By Lisa McDonald / August 30, 2019

In May, a formula was published that could describe thermal transport in both crystals and glass. Now, a new formula by researchers in Italy and the United States based on a different mathematical framework can also model such thermal transport.
