Understanding roughness on a small scale: The origin of self-affinity

By Lisa McDonald / February 28, 2020

Roughness plays a big role in determining friction and adhesion between materials, which greatly affects processes in both scientific and industrial fields. So understanding roughness can help control these factors. Researchers led by the University of Freiburg investigate the origins behind a particular characteristic of roughness—self-affinity.

A tale of two SiC slurries—and how open science may someday impact research

By Jonathon Foreman / February 25, 2020

Fabricating dense, complex-shaped items from silicon carbide can be challenging due to the material’s properties. Manufacturers benefit from studies on reducing viscosity of SiC slurries, such as two recent ones published in an ACerS journal, but open access to the data behind such studies may benefit them even more.

A creeping suspicion—modified concrete creep model considers drying-induced damage

By Lisa McDonald / February 21, 2020

Existing creep damage models for concrete assume compressive and tensile creep are identical, but recent experimental evidence suggests otherwise. Researchers from the United Kingdom and China propose a modified model that accounts for drying-induced damages and load eccentricity to more accurately model creep.
