Programmable Microgel Degradation in Dynamic Granular Hydrogels Guides Extracellular Matrix Assembly During Tissue Repair

open access: yesAdvanced Materials, EarlyView.
This study reports on the chemical modification of hyaluronic acid to create hydrogels with hydrolytic degradability ranging from 2–28 days. Granular hydrogels that undergo timed degradation to increase porosity enhance cell invasion and provisional ECM remodeling in a muscle injury model, leading to reduced fibrosis and improved regeneration ...

Binder‐Free Direct Ink Writing of Li6.4La3Zr1.4Ta0.6O12 Garnet Electrolytes for All‐Solid‐State Batteries

open access: yesAdvanced Materials Interfaces, EarlyView.
Polymer binders and thick pressed LLZTO pellets limit all‐solid‐state battery integration through grain‐boundary carbon and high ohmic losses. A binder‐free capillary suspension ink is direct‐ink‐written and sintered into 254 μm$\mu{\rm m}$, 95.8%‐dense Ta‐stabilized LLZTO with 17.3 mS cm−1$\text{cm}^{-1}$ bulk conductivity, enabling thinner ...

Amphiphilic Non‐Isocyanate Polyurethane Coatings With Tunable Antifouling and Fouling‐Release Performance: A Log‐Ratio Assessment Framework

open access: yesAdvanced Materials Interfaces, EarlyView.
Amphiphilic non‐isocyanate polyurethane (NIPU) coatings containing reactive hydrophobic poly(dimethylsiloxane) (PDMS) and hydrophilic methoxy poly(ethylene glycol) (MPEG) prepolymers for marine antifouling (AF) and fouling‐release (FR) applications were investigated. The coatings were evaluated with a set of representative marine foulants.

Scalable Fabrication of Chemically Stabilized Gelatin Hydrogel Fibers by Thermal Drawing

open access: yesAdvanced Materials Interfaces, EarlyView.
Scalable processing of hydrogel fibers remains a major challenge. By coupling thermal drawing with Maillard chemistry, a transient viscous‐flow window is created that enables continuous fabrication of microstructured gelatin fibers tens of meters long, while continued in situ crosslinking during drawing stabilizes the fibers for physiological ...
