Summary: The microstructure, mechanical properties, corrosion, wear behavior, and cytocompatibility of in situ Zn-Mg-Mg2Si alloys with different Mg2Si contents were evaluated. Increasing Mg-10Si content improved the mechanical strength, hardness, and wear resistance, but decreased the corrosion rate and cytocompatibility. The Zn-Mg-0.6Mg2Si alloy exhibited the best matching with moderate UTS, YS, hardness, wear loss, degradation rate, and cell viability, making it a preferable candidate for biodegradable bone-implant materials.

Summary: This study successfully prepared porous magnesium-zinc (Mg-xZn, x: mass ratio of Zn) scaffolds by the 3D gel-printing method. The effect of adding a large percentage of Zn content on porous Mg-xZn scaffolds was also investigated to comprehensively evaluate the effect of Zn on magnesium alloys. The viscosity of slurry decreases with the increase in Zn content. The optimum solid content of slurry suitable for printing is about 60%. The compressive strength of pure Mg, 0.9Mg-0.1Zn, 0.7Mg-0.3Zn, and 0.5Mg-0.5Zn porous scaffolds were 6.29 MPa, 13.03 MPa, 7.69 MPa, and 6.61 MPa, respectively, meeting the requirements of cancellous bone (0.1-16 MPa). In vitro degradation results showed that the degradation rate of Mg scaffolds can be slowed down by adding the appropriate amount of Zn. The fine and dispersed second-phase precipitation can improve the comprehensive properties of Mg-Zn alloy. This study facilitates a comprehensive evaluation of the effect of Zn content on 3D gel-printed magnesium scaffolds.

Summary: Limitations in practical implementations of ZnO nanomaterials can be overcome by doping Mg2+ ions into ZnO nanostructures. The doping process results in the shrinkage of crystallite size and morphological changes in ZnO. Doped ZnO also exhibits enhanced UV absorption and emission intensities, with calculated bandgap values ranging from 3.34 eV to 3.57 eV. Additionally, Mg-doped ZnO diodes show improved rectification behavior and electrical properties, with the ideality factor value of 3.1 for 5% Mg2+ doping. Furthermore, 100% degradation of methylene blue is achieved via piezo-photocatalytic effect in Mg-doped ZnO.
