Oxygen Defect Engineering of Hexagonal Perovskite Oxides to Boost Catalytic Performance for Aerobic Oxidation of Sulfides to Sulfones

open access: yesAdvanced Functional Materials, EarlyView.
Ru‐substituted hexagonal perovskite SrMnO3, featuring face‐shared oxygen species, is designed as an effective heterogeneous catalyst for the aerobic oxidation of sulfides. The catalyst demonstrates high selectivity to sulfones (>99%) under mild reaction conditions (≥30 °C). Ru substitution promotes oxygen vacancy formation of face‐shared oxygen species

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

open access: yesAdvanced 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.

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

open access: yesAdvanced 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 ...
