Tannic acid–metal biomaterials for skin repair: Principles, immune microenvironment modulation, and translational perspectives

BMEMat, EarlyView.
Tannic acid–metal materials are emerging as versatile wound biomaterials, but their value depends on more than multifunctionality. This review maps how tannic acid alone, free metal ions, and coordinated TA–metal systems differ in design logic, immune‐microenvironment effects, and translational potential, offering a practical framework for choosing ...

Carbon‐Embedded Fe‐Cu Composite Oxide Nanoparticles Derived From Spindle‐Shaped Bimetallic MOFs for Selective Oxidation of Methane

Carbon and Hydrogen, EarlyView.
Fe3Cu1/C (CuFe5O8) was synthesized by high‐temperature carbonization of FexCuyBDC MOF, which exhibited excellent catalytic performance for methane selective oxidation at 80°C. The synergistic effect between Cu and Fe in the derived Fe3Cu1/C (CuFe5O8) composite oxide inhibits deep oxidation compare to Fe/C (Fe3O4), and the reaction proceeds via a free ...

Interfacial Electron‐Modulated Pt Sites on Self‐Supported NiCoP Nanosheets for Enhancing Hydrogen Evolution Reaction

Carbon Energy, EarlyView.
Using a hierarchical multilevel‐structure strategy, we design and prepare a self‐supported Pt/NiCoP/CF catalyst with a strong electron transfer effect between Pt and NiCoP. This catalyst realizes highly efficient HER performance under full pH range, outperforming commercial Pt/C catalyst.

Interface‐Engineered Li–Ni–O/Ni Heterostructures With Tunable Vacancies on Biochar Enable Biomass‐to‐Hydrogen Conversion

Carbon Energy, EarlyView.
This study shows that lithium induces Li–Ni–O/Ni heterostructures on biochar, creating oxygen vacancies and optimal acid–base environments that enhance steam activation and suppress carbon deposition. These interfacial effects and synergistic modulation lead to high hydrogen yields at moderate temperatures, providing a scalable catalyst design strategy
