Recently, the high ductility of Cu-based bulk metallic glasses (BMGs) has been directly linked to the presence of Y2O3 precipitates, and surrounding crystallized areas. Nevertheless, the formation of the precipitates remains to be defined. In this wo

International audience; Nacre-like aluminas are bio-inspired, ceramic-based composites that display high toughness and strength. Their toughness arises from their brick-and-mortar microstructure. We must understand the role of several microstructural

The conception of cheaper and greener electrode materials is critical for Li-ion battery manufacturers. In this study, it is shown that a by-product of the carbothermic reduction of SiO2 to Si, containing Si, SiC and C materials, can be valorized as
