Extremely well-deserved for a team of brilliant young scientists and wonderful people, including some true #friends. I’m sure there’s much more to come from them. Keep an eye out!
Phase field #numerical #simulations well reproduces key features from #Molecular #Dynamics simulations and experimental GB velocity–curvature distributions.
We discuss the key role of shear deformation accompanying grain boundary (GB) migration (shear coupling) in driving #microstructure #evolution (grain growth) in single-component #polycrystals.
Grain growth is typically modeled as driven by GB energy reduction, but recent #simulations and #experiments show this is overly simplistic, even when accounting for anisotropies in mobility and GB energy. Shear-coupled GB migration allow for reconciling recent evidence.
To show this point, we extended a shear-coupled interface migration model www.sciencedirect.com/science/arti...) to full microstructures with the aid of a #multi-phase-field approach.
I am honored to have contributed to practically "taking care of the #thermodynamic #limit". Indeed, one of the best pastas I have ever eaten, in one of the best atmospheres ever (the glorious WG of Bautzi 27 in Dresden).
Amazing news from the #IgNobel prizes! 🤩
The physics prize went to the team outlining the "Phase behavior of Cacio e Pepe sauce": improbable.com/ig/winners/
