A Visible Light‐Responsive Hydrogel to Study the Effect of Dynamic Tissue Stiffness on Cellular Mechanosensing

Advanced Functional Materials, EarlyView.
A visible light‐responsive polyacrylamide‐azobenzene hydrogel enables safe, reversible stiffness control for studying cell mechanobiology without harmful UV exposure. This approach reveals stem cells respond rapidly to mechanical changes, showing altered shape and protein distribution within one hour.

Mg2+/Al3+ Co‐doped Li‐Rich Manganese‐Based Oxides for Boosting Rate Performance and Stability of Lithium‐Ion Batteries

Advanced Functional Materials, EarlyView.
The co‐doping strategy can effectively address the challenges associated with LRMOs cathode materials, providing a promising pathway for the development of high energy density and resilient cathode materials in the next‐generation lithium‐ion batteries. Abstract Lithium‐rich manganese‐based oxides (LRMOs) are promising cathode materials for lithium‐ion

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels

Advanced Functional Materials, EarlyView.
A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Transmembrane Activation of Catalysis and Protein Refolding in Synthetic Cells by Enzymes and Nanozymes

Advanced Functional Materials, EarlyView.
Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.
