Summary: The microstructure, mechanical property and in vitro degradation behavior of Mg-2Zn-0.2Zr-xNd (ZK-xNd, x = 0.2, 0.6, 1.0, wt%) alloys were investigated. The addition of 1.0% Nd in Mg-2Zn-0.2Zr (ZK) alloy improved the grain refinement, promoted the formation of MgZn2Nd phase and weakened the basal texture. The as-extruded ZK0.2Nd alloy exhibited low degradation rate and showed no cytotoxicity on HUVEC cells, but no significant change in tensile strength and ductility was observed due to less solid solution strengthening and the premature failure caused by incoherent interfaces.

Summary: In this study, a new type of biodegradable binary zinc (Zn) alloys incorporating 16 rare earth elements (REEs) was developed and its microstructure, mechanical properties, corrosion behavior, in vitro and in vivo biocompatibility were systematically investigated. The results showed that Zn-RE alloys generally exhibited improved mechanical properties and biocompatibilities compared to pure Zn, especially the tensile strength and ductility. Y, Ho, and Lu were the elements that displayed the greatest improvements, while Eu, Gd, and Dy exhibited the least improvement. The Zn-RE alloys also exhibited superior properties compared to other Zn and Mg-RE alloys. The in vivo experiment demonstrated the excellent tissue biocompatibility and osseointegration of the Zn-RE alloys as tibia bone implants in rabbits. This work highlights the significant potential of the developed Zn-RE binary alloys as novel degradable metals for biomedical implants and devices.

Summary: The energy transfer and efficiency of ultrasound to piezoelectric materials play a crucial role in the catalytic performance and therapeutic effects for deep infection diseases. The microbubble cavitation near the surface of BTO/Ber NPs under ultrasound leads to sonoluminescence and high pressure, further activating Ber and enabling electron transfer with changing energy levels of BTO NPs. The piezoelectric electron-phonon coupling caused by ultrasound narrows bandgap and prolongates carrier-lifetime, resulting in increased ROS generation and antibacterial activity against Staphylococcus aureus.

Summary: Magnesium alloy is a biodegradable material with a modulus similar to bone and has the potential to be used as a bone grafting material. Oxidation heat treatment is an effective passivation method that can slow down the degradation of magnesium alloy. The cytotoxicity and osteogenic induction experiments showed that oxidation heat-treated scaffolds exhibited good biocompatibility and accelerated cell proliferation, leading to increased alkaline phosphatase activity, mineralized nodule quantity, and bone growth marker protein expression. Therefore, oxidation heat-treated 3D printing scaffolds have great potential in fixing bone defects as advanced biomaterials.

Summary: This study investigated the effects of pore size on the mechanical properties, biodegradation, and new bone formation of additively manufactured biodegradable porous magnesium scaffolds. It was found that high temperature oxidation improved the corrosion resistance of the magnesium scaffold. Scaffolds with a pore size of 500μm showed better mechanical characteristics and supported the survival of mesenchymal stem cells without local toxicity. They also released more magnesium ions and improved the osteogenic differentiation of bone mesenchymal stem cells compared to scaffolds with larger pore sizes. In a rabbit femoral condyle defect model, the 500μm group exhibited unique performance in promoting new bone formation, indicating its potential for bone defect regeneration therapy.

Summary: A novel compliant spinal fixation based on compliant mechanisms is designed to effectively reduce stress-shielding effect and adjacent segment degeneration (ASD), but it requires high properties of the used materials. Bulk metallic glasses (BMGs), as young biomaterials, demonstrate excellent comprehensive properties, making them attractive for compliant spinal fixation. In this study, the large deflection deformation behaviors of Zr61Ti2Cu25Al12 (at.%, ZT1) BMG beam were systematically investigated, including elastic, yielding, and plastic deformations. The theoretical nonlinear analytical solution curve predicts the load-deflection relation within the elastic deformation regime and assists in capturing the yielding event, serving as a powerful design tool for engineers. To accurately capture the beginning of the yielding event in biomedical implant applications, the concept of bending proof strength (sigma p,0.05%) with tiny permanent strain of 0.05% was proposed and determined, which is significant for setting the allowable operating limits of the basic flexible elements. The plastic deformation driven by the bending moment can be classified into two stages: the initial stage characterized by nucleation and intense interaction of shear bands, and the second stage dominated by the progressive propagation of shear bands and emergence of shear offsets. The plasticity of BMG beam structures depends on the BMG's inherent plastic zone size (rp), and when the half beam thickness is less than that of rp, the plastic deformation of BMGs behaves in a stable manner, effectively serving as the margin of safety.

Summary: Fe-based metallic glasses are promising materials in the fields of advanced magnetism and sensors. This study proposes a novel approach to tailor the amorphous structure through liquid-liquid phase transition, and provides insights into the correlation between structural disorder and magnetic order. The results show that the liquid-liquid phase transition can induce more locally ordered nanodomains, leading to stronger exchange interactions and increased saturation magnetization. The increased local heterogeneity also enhances magnetic anisotropy, resulting in a better stress-impedance effect.

Summary: Metal-organic frameworks derived composites are promising EMW absorbers. Cation substitution can improve their absorption performance by regulating morphology and atomic space occupation. However, the mechanisms of how cation substitution affects EMW absorption performance are still not well understood. In this study, imidazolic MOFs were fabricated and tailored by cation substitution strategy to prepare porous composites. The samples showed optimal reflection loss and effective absorption bandwidth values under low filling rate and thin thickness conditions. The intercoupling between multiple atoms and the porous structure introduced by cation substitution contribute to the improved absorption performance.
