Nanoscale Covalent Organic Framework Confinement Enables Ultratough and Hyperelastic Hydrogels Applied as High‐Performance Electrolytes

open access: yesAdvanced Science, EarlyView.
Confinement by nanoscale covalent organic frameworks reinforces hydrogels, imparting exceptional mechanical strength and ionic conductivity for high‐performance electrolyte applications. ABSTRACT Hydrogels are widely applied in various fields, including energy storage and flexible electronics. However, their mechanical properties often fail to meet the

Breaking the Toughness‐Stretchability Trade‐Off in Hydrogels with Dynamic Hydrogen Bonding

open access: yesAdvanced Science, EarlyView.
A novel nanocomposite hydrogel architecture overcomes the inherent conflict between toughness and stretchability by integrating uniformly dispersed aminopropyl‐hybrid‐phyllosilicate nanosheets within a polyacrylamide matrix. This design leverages a dynamic hydrogen‐bonding network to facilitate efficient energy dissipation and self‐recovery.

Deformation‐Induced Formation of Stray Grains in Additive Manufacturing of Single Crystals

open access: yesAdvanced Science, EarlyView.
Stray grain formation severely limits the additive manufacturing of single‐crystal alloys. By integrating in situ synchrotron techniques, ex situ characterization, and multi‐scale multi‐physics modeling, the authors reveal that stray grains originate from dislocations at the solid‐liquid interface, rather than thermal supercooling in conventional ...

Bioinspired Microphase‐Engineered Binders for Silicon Anodes

open access: yesAdvanced Science, EarlyView.
Inspired by the tough exoskeleton of Phloeodes diabolicus, a bio‐based binder featuring LRA–click chemistry and hierarchical crosslinking forms well‐defined microphase‐separated structures that enable robust silicon anodes. This system promotes the formation of a LiF–rich, ultrathin SEI (∼17 nm) with high modulus and ionic conductivity, ensuring long ...

Mechanism of Solid Solution‐Driven Texture Induced by Ag Doping in YBCO Superconductor

open access: yesAdvanced Science, EarlyView.
Ag‐doped YBCO with a designed concentration gradient is produced by dual‐material co‐extrusion and freeze‐drying. During annealing, Ag+ ions diffuse into Y123, substituting for Cu(1) and inducing c‐axis relaxation. This leads to the formation of [001]‐oriented YBCAO, creating a coherent interface that templates the textured growth of Y123. Consequently,

Review: Insight on Porous Carbon Positive Electrode for Sodium‐Ion Capacitors: Interplay Between Synthesis, Properties, and Performance

open access: yesAdvanced Science, EarlyView.
Sodium ion capacitor (SIC) is currently constrained by the low discharge capacity of commercial activated carbon as positive electrode material. This review provides a holistic summary of research efforts on alternative porous carbon materials for SIC. Image created by the authors with www.biorender.com.
