Photocatalytic Versus Stoichiometric Hydrogen Generation Using Mesoporous Silicon Catalysts: The Complex Role of Sacrificial Reagents

Advanced Functional Materials, EarlyView.
This study highlights the importance of accounting for stoichiometric hydrogen produced when utilizing Si photocatalysts. The stoichiometric contribution is sacrificial reagent dependent and decreases with increasing sterics around the catalyst surface.

Highly Active Air Electrode with Enhanced Proton Conduction via Isovalent Doping in a Layered Perovskite for Reversible Protonic Ceramic Cells

Advanced Functional Materials, EarlyView.
A Ni‐doped PBSCN20 air electrode is proposed as a promising air electrode material for reversible protonic ceramic cells. An isovalent doping significantly facilitates oxygen vacancy formation and proton uptake while simultaneously reducing the energy barrier for proton migration.

Biomass Native Structure Into Functional Carbon‐Based Catalysts for Fenton‐Like Reactions

Advanced Functional Materials, EarlyView.
This study indicates that eight biomasses with 2D flaky and 1D acicular structures influence surface O types, morphology, defects, N doping, sp2 C, and Co nanoparticles loading in three series of carbon, N‐doped carbon, and cobalt/graphitic carbon. This work identifies how these structural factors impact catalytic pathways, enhancing selective electron

Enhanced Sonodynamic Bacterial Elimination and Wound Healing Therapy Based on Lanthanide Ion Doped Bi2WO6 Nanosheets and Hydrogel Platform

Advanced Functional Materials, EarlyView.
Lanthanide ytterbium ions are introduced into Bi2WO6 nanosheets to boost ROS generation under US stimulation. These ytterbium‐doped Bi2WO6 nanosheets serve as efficient sonosensitizers, enabling broad‐spectrum bacterial eradication. To improve biocompatibility for in vivo sonodynamic therapy, the sonosensitizers are integrated into hydrogel matrix ...

Antioxidant and Anti‐Senescence Polyvinyl Alcohol‐Gallic Acid Supramolecular Hydrogels for Stem Cell Culture

Advanced Healthcare Materials, EarlyView.
The PVA‐GA hydrogel is formed through hydrogen bonding between PVA hydroxyl groups and GA galloyl units, enabling sustainable GA release and its extended biological activity. The hydrogel scavenges ROS to reduce oxidative stress, preventing mitochondrial damage from excessive ROS, mitigating hADSC senescence, and preserving VEGF secretion, offering a ...
