Molecular‐Grafting‐Induced Anion Immobilization in Polymer Electrolytes for High‐Transference‐Number and Dendrite‐Free Solid‐State Lithium Batteries

Electron, EarlyView.
By grafting lithium phenylsulfonate onto a PVDF backbone, we create a solid electrolyte that immobilizes anions and enhances Li+ transport. This results in a high Li+ transference number (0.67) and uniform ion flux, enabling stable, dendrite‐free cycling in lithium metal batteries.

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

Energy Science &Engineering, EarlyView.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...
