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.

Multiscale Architecture and Mechanics of the Cell Nucleus: Implications for Disease, Bioengineering and Nanomedicine

open access: yesAdvanced Science, EarlyView.
Nuclear mechanical properties are inherently scale‐dependent, arising from a hierarchical architecture that spans DNA, chromatin, the nuclear envelope, and condensates. Experimental techniques and theoretical models are integrated into a cohesive multiscale framework linking nanoscale structural features to organelle‐level mechanical behavior.

Plastic buckling of initially imperfect stiffened cylinders in axial compression

open access: yes, 1981
Bibliography: leaves 117-118.Bifurcation in the plastic range of axially compressed stringer-stiffened cylinders is investigated. The shell under consideration is assumed to have an initial imperfection in the form of a sinusoidal deviation both axially ...

A Piezo‐Mimetic Ionic Hydrogel Harnessing Joint Motion for Cartilage Repair

open access: yesAdvanced Science, EarlyView.
A piezo‐mimetic ionic hydrogel converts mechanical deformation into bioactive ionic currents via stress‐induced asymmetric ion migration. Coupled with sustained Mg2+ release, this mechano‐electrochemical platform bridges mechanical loading and cellular signaling, enabling load‐adaptive stimulation and enhanced cartilage regeneration.

Structurally Complex Precipitates Enhance Strength‐Ductility Synergy in a Duplex Medium Entropy Alloy

open access: yesAdvanced Science, EarlyView.
Strong‐yet‐ductile precipitation‐hardening alloys require novel microstructural complexity of precipitates in particularly at cryogenic condition, to constantly impart strain hardening of hard‐and‐brittle precipitates. The present work creates innovative structurally complex precipitates assembled with dispersed nanocores and a chemical‐heterogeneity ...
