Enabling and Boosting Preferential Epitaxial Zinc Growth via Multi-Interface Regulation for Stable and Dendrite-free Zinc Metal Batteries

The practical application of aqueous Zn-metal anodes (AZMAs) is mainly impeded by the short cycling life and unsatisfactory reversibility springing from the notorious Zn dendrite growth and detrimental water-induced parasitic reactions at anode…

Formulation variationnelle de l'endommagement anisotrope dans les matériaux quasi-fragiles et régularisation par l'approche Lip-field

When submitted to mechanical loadings, quasi-brittle materials experience gradual damage. This process stems from the development of micro-cracks inside a finite volume of matter. These micro-cracks are by nature anisotropic, oriented by the…
