Dynamic, Reconfigurable, and Hierarchical Biosynthetic Composites via Collagen Self‐Assembly within Highly Crowded Microgel Pastes

open access: yesAdvanced Materials, EarlyView.
A new approach to extracellular matrix‐mimetic, hierarchical biomaterials is presented. Soft gels composed of overpacked hydrogel microparticle arrays present a biomolecularly crowded environment permissive to the self‐assembly of collagen networks.

Improving Ionic Conformality Across Polymer Electrolyte|Electrode Interfaces

open access: yesAdvanced Materials, EarlyView.
Polymer electrolytes typically form physically intimate electrode interfaces but often fail to maintain continuous ionic pathways, critically limiting battery performance. Through strategic compositional design, this study introduces a molecular ionic composite electrolyte that effectively reduces interfacial ionic depletion, ensuring consistent ion ...

Decoupling Dynamics and Crosslink Stability in Supramolecular Hydrogels Using Associative Exchange

open access: yesAdvanced Materials, EarlyView.
How does reorganization impact the stability of supramolecular hydrogels? In contrast to dissociative crosslink exchange, implementing associative exchange in macroscale DNA hydrogels enables decoupling of reorganization dynamics from thermal and mechanical stability.

Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.
