Chlorine Transport Governs Chemical Stability at Halide-Sulfide Dual-Electrolyte Interfaces in All-Solid-State Batteries

This study utilizes machine-learned force fields and molecular dynamics simulations to reveal that chlorine transport kinetics, rather than thermodynamic stability, govern the chemical degradation at halide-sulfide electrolyte interfaces in all-solid-state batteries, demonstrating that disordered anion sub-lattices can suppress degradation by disrupting long-range migration pathways.

Aged Cementitious Matrices Recovery in Hydraulic Structures using Colloidal Nanosilica Diffusion

This study demonstrates that a colloidal nanosilica-based repair product (Elera) effectively recovers the degraded cementitious matrix in highly porous aged concrete from hydraulic structures through diffusion-induced pozzolanic reactions, while highlighting the need for alternative injection methods for denser samples to enable sustainable infrastructure maintenance.
