Diabetic alveolar bone defect (DABD) causes persistent bacterial infection, prolonged inflammation, and delayed bone healing, making it a considerable clinical challenge. In this study, by integrating silver nanoclusters (AgNCs) and M2 macrophage‐derived extracellular vesicles (M2EVs), a multifunctional DNA‐based hydrogel, called Agevgel, is developed with antibacterial, anti‐inflammatory, immunomodulatory,...
Developing high‐efficiency and stable oxygen evolution reaction (OER) electrocatalysts is an imperative requirement to produce green and clean hydrogen energy. In this work, the FeCoSy/NCDs composite with nitrogen‐doped carbon dots (NCDs) modified Fe–Co sulfide (FeCoSy) nanosheets is prepared by using a facile and mild one‐pot solvothermal method. Benefiting from the low crystallinity and the synergistic...
Stable platforms of host–guest catalysts are indispensable in the field of heterogeneous catalysis, however, clarifying the specific effect of host remains challenging. Herein, polyoxometalate (POM) is encapsulated in three types of UiO‐66(Zr) with different controlled densities of defects by the aperture opening and closing strategy at ambient‐temperature. It is found that catalytic activity of POM...
