SmartMat, Volume 6, Issue 1, February 2025.The inherent brittleness of poly(lactic acid) (PLA) was addressed by incorporating indium selenide (InSe) particles and flakes as a reinforcing filler. The PLA/InSe composites are 1.5 times stronger and 5.5 times tougher than neat PLA materials. Compared with other fillers, InSe enables PLA to achieve better concurrent improvement in tension strength ...

Weakening Induced by Phase Nucleation in Metamorphic Rocks: Insights From Numerical Models
Geochemistry, Geophysics, Geosystems, Volume 25, Issue 11, November 2024.Abstract Metamorphic transformations involve important changes in material properties that can be responsible for rheological alterations of rocks. Studying the dynamics of these changes is therefore crucial to understand the weakening frequently observed in reactive rocks undergoing deformation. Here, we explore the effects of reaction dynamics on the
