The Zn metal anode in aqueous zinc‐ion batteries (AZIBs) faces daunting challenges including undesired water‐induced parasitic reactions and sluggish ion migration kinetics. Herein, we develop three‐dimensional covalent organic framework (COF) membranes with bioinspired channels toward stabilized anodes. These COFs, featured by zincophilic pyridine‐N sites, enable effective regulation of water molecules at the anode‐electrolyte interphase. Systematic experimental analysis theoretical...
High-resolution x-ray photoelectron spectroscopy (XPS) was applied to characterize the electronic structures for a series of high-k materials (HfO2)x(Al2O3)1−x grown on (100) Si substrate with different HfO2 mole fraction x. Al 2p, Hf 4f, O 1s core levels spectra, valence band and energy loss all show continuous changes x in (HfO2)x(Al2O3)1−x. These data are used estimate gap (Eg) (HfO2)x(Al2O3)1−x, offset (ΔEν) conduction (ΔEc) between substrate. Our XPS results demonstrate that values Eg,...
Accumulating evidence indicates that intracellular reactive oxygen species (ROS) production is highly involved in bone homeostasis by intervening osteoclast or osteoblast differentiation. Interestingly, ROS are known as oxidizing agents exert dose-dependent biphasic properties remodeling, including preventing activity but accelerating resorption. mainly composed of superoxide anion radical, hydroxyl nitric oxide, and two-electron reduction product hydrogen peroxide, which important...
Polyetheretherketone (PEEK) has been widely used as orthopedic and dental materials due to excellent mechanical physicochemical tolerance. However, its biological inertness, poor osteoinduction, weak antibacterial activity make the clinical applications in a dilemma. Inspired by mussel adhesion mechanism, here we reported biomimetic surface strategy for rational integration optimization of anti-infectivity osteo-inductivity onto PEEK surfaces using foot proteins (Mfps)-mimic peptide with...
