Microenvironmental Reprogramming by 3D Anisotropic Cardiac Extracellular Matrix Induces Nuclear Remodeling and Epigenetic Maturation of Chemically Induced Cardiomyocytes

Advanced Functional Materials, EarlyView.
A 3D anisotropic hydrogel derived from heart extracellular matrix guides cytoskeletal alignment and nuclear remodeling in reprogrammed cardiomyocyte‐like cells. This study reveals how matrix alignment modulates nuclear envelope dynamics and chromatin state, triggering transcriptional and functional maturation.

Tuning Separator Chemistry: Improving Zn Anode Compatibility via Functionalized Chitin Nanofibers

Advanced Functional Materials, EarlyView.
Nanochitin derived from waste shrimp shells is used to fabricate separators for aqueous zinc batteries. By tuning the density of amine and carboxylic surface groups, water mobility at the separator interface is controlled, promoting uniform zinc deposition, suppressing dendrite growth, and enabling exceptional cycling stability exceeding 2000 h ...
