“…[103] In addition, when excessive Zn ions come into contact with the cell membrane of bacteria, it will regulate the enzymatic reactions related to the cell membrane, destroy the absorption of Ca ions, change the permeability of the cell membrane, and thus achieve the sterilization effect. [104] Therefore, Zn ions have antibacterial effects on the S. aureus. [105,106] As a widespread antibacterial ion, Cu ions bind to negatively charged regions of bacteria through an electrostatic effect, causing rupture of the outer membrane of bacteria, damaging the nucleic acid structure, changing the bacteria osmotic pressure, and weakening the activity of cell synthetase.…”

Zinc (Zn) and its alloys have recently gained research interest due to their good biosafety, biological function, biodegradability, and formability. Zincphosphate (ZnP) coating has been shown to improve the corrosion resistance and biocompatibility of Zn alloys. Here, a biodegradable ZnP-coating on Zn1Cu0.1Ti (ZCT) membrane with high strength-ductility and mechanical stability, suitable degradation rate, effective antibacterial ability, excellent in vitro and in vivo cytocompatibility, and osteogenesis is reported. The ZnPcoated ZCT exhibits high strength-ductility with a yield strength of 264 MPa, ultimate tensile strength of 312 MPa, elongation of 36.0%, and high mechanical stability before and after 30 d immersion in Hanks' and AS solutions, all of which are higher than those of ZCT. The ZnP coating shows good deformation resistance, healing effect, and bond strength with the substrate, meeting the clinical contour shaping requirements. The ZnP-coated ZCT membrane sample shows higher cell viability toward MC3T3-E1 and MG-63 cells, osteogenic and mitochondrial quality-control properties in vitro than those of the ZCT sample. Using a rat calvarial defect model, the ZnP-coated ZCT membrane shows complete biosafety and considerable osteogenesis performance. Overall, the ZnP-coated ZCT membrane is recommended as a promising biodegradable implant material for oral guided bone regeneration application.

“…[149][150][151] In terms of the issue of nanoparticle separation, the magnetic separation method is commonly employed. [149,152,153] However, the preparation process of carbonaceous materials will become extremely complex for solving the above problem simultaneously. Therefore, researchers started working on the photothermal film to simultaneously address these two problems.…”

The photothermal process has attracted considerable attention in water treatment due to its advantages of low energy consumption and high efficiency. In this respect, photothermal materials play a crucial role in the photothermal process. Particularly, carbonaceous materials have emerged as promising candidates for this process because of exceptional photothermal performance. While previous research on carbonaceous materials has primarily focused on photothermal evaporation and sterilization, there is now a growing interest in exploring the potential of photothermal effect‐assisted advanced oxidation processes (AOPs). However, the underlying mechanism of the photothermal effect assisted by carbonaceous materials remains unclear. This review aims to provide a comprehensive review of the photothermal process of carbonaceous materials in water treatment. It begins by introducing the photothermal properties of carbonaceous materials, followed by a discussion on strategies for enhancing these properties. Then, the application of carbonaceous materials‐based photothermal process for water treatment is summarized. This includes both direct photothermal processes such as photothermal evaporation and sterilization, as well as indirect photothermal processes that assisted AOPs. Meanwhile, various mechanisms assisted by the photothermal effect are summarized. Finally, the challenges and opportunities of using carbonaceous materials‐based photothermal processes for water treatment are proposed.

“…[39][40][41] Bimetallic MOFs that combine two different metal ions as nodes in their molecular frameworks have recently attracted increasing attention, due to the need for the production of high-performance materials with high adsorption capacity and synergistic functionalities. 42,43 Although many reports exist on the fabrication of MOF derivatives, there are few studies on the direct carbonization of bimetallic MOFs to obtain functional materials. 44 Therefore, the integration of PDMS and bimetallic MOF-derived carbons with high porosity and rich adsorptive sites will enhance the adsorptive capacity and mechanical strength of PDMS and be ideal for the efficient extraction of volatile compounds in spices.…”
