Summary: This study investigates the corrosion behavior and mechanical properties of an extruded Mg-4Li-1Ca alloy under different micro-compressive stresses. The results show that micro-compressive stress can induce grain growth and precipitation of second-phase particles, accelerating the corrosion rate. However, when the stress level reaches a certain point, the volume fraction of the second phase becomes the dominant factor controlling the corrosion rate, and residual stress is released, forming corrosion product films that weaken the microstructural effect on corrosion behavior.

Summary: The tensile behavior of extruded and peak-aged Mg-5Gd-3Y-xZn-0.5Zr alloys was investigated in terms of microstructural evolution, deformation modes, and mechanical properties at temperatures ranging from -100℃ to 300℃. The study found that the Zn content affected the distribution of intragranular and interdendritic phases, which in turn influenced the mechanical properties of the alloys. Additionally, the deformation modes during tensile testing were influenced by factors such as testing temperature, grain orientation, and LPSO morphology.

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: Mg-Zn alloys are promising as biodegradable materials due to their excellent mechanical properties and biocompatibility, but their corrosion behavior poses challenges for biomedical applications. By constructing Pourbaix diagrams based on first principles, researchers found that different alloy compositions exhibit unique corrosion mechanisms, such as galvanic corrosion in Mg-rich alloys and Zn corrosion in Zn-rich alloys. The presence of Cl ions in the environment has also been shown to influence the corrosion behavior of the alloys, highlighting the importance of understanding the alloy's degradation mechanisms for future design improvements.

Summary: In this study, the microstructure, mechanical properties, and corrosion behavior of Mg-1.8Zn-0.5Zr alloys with different Gd additions were investigated. It was found that the grain size decreased gradually with Gd alloying. The mechanical properties and corrosion resistance of the alloys first improved and then weakened with increasing Gd content. The optimal mechanical properties and corrosion resistance were achieved with a 1.5 wt.% Gd addition. A three-stage corrosion mechanism was proposed through electrochemical measurements and corroded surface analyses.

Summary: In this study, the effects of the Fe/Ni ratio on the microstructure, mechanical properties, and corrosion resistance of FexNi65-xCr20Al10Nb5 alloy in a 3.5 wt% NaCl solution were systematically investigated. It was observed that the dominant phases shifted from FCC to BCC with an increase in the Fe/Ni molar ratio. The strength of the alloy increased with a higher Fe/Ni ratio, while the plasticity decreased. The alloy exhibited the best corrosion resistance when x = 35, which was attributed to the dominant presence of FCC phases in the dendritic region.

Summary: In this study, a biodegradable alloy of zinc-lithium (Zn-Li) was coated with a resorbable tricalcium phosphate (Mn,Sr-TCP) doped with manganese and strontium using the Pulsed Laser Deposition method. The coating was characterized using various techniques, and microbiology experiments were performed to test the growth inhibition of bacteria strains and fungus. The results showed that the Mn,Sr-TCP-coated Zn-Li samples exhibited about 10% inhibition on the growth of all four bacteria strains and had the most pronounced effect on Candida albicans fungus (about 50% inhibition of growth). The prepared coatings have the potential to improve the degradation behavior and biological characteristics of Zn-Li alloys.

Summary: Sonodynamic therapy (SDT) has attracted attention for treating deep-seated tumors or infections due to its non-invasiveness and high tissue-penetrating ability. This study develops a defective homojunction porphyrin-based metal-organic framework (MOF) that greatly enhances sonocatalytic ability for SDT of MRSA-infected osteomyelitis. The MOF structure is modified using acetic acid and benzoic acid, and the defect-induced homojunction structure is found to improve the SDT effect by enhancing ultrasound-triggered reactive oxygen species production.

Summary: Through the integration of thermodynamic databases, first-principles calculations, phase field simulations, and experiments, this study reveals the coupling between the shuffle (O ') and shear (alpha'', orthorhombic martensite) nanodomains in Ti-Nb alloys. The transformation path changes with Nb concentration, and the resulting microstructural states exhibit an unprecedented continuous transformation behavior with superelasticity and almost zero hysteresis. This research provides new insight in alloy design by utilizing composition-dependent shuffle-shear coupling during a structural phase transformation.

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: In order to reduce the occurrence of restenosis and thrombosis in stents, it has been clinically proven that using a thinner-strut stent is effective. Therefore, there is a current trend towards using ultrathin-strut (<= 70 μm) designs for durable stents. However, stents made from biodegradable platforms have not been able to achieve breakthroughs across generations due to their excessively thick struts.

Summary: Microwave (MV)-trigged dynamic therapy using MV-responsive materials shows promise for treating deep infection diseases, including life-threatening osteomyelitis, that are not effectively treated by antibiotics. Surface states of materials play a key role in the generation of free charges and the MV dynamic effects. A new MV responsive system, consisting of a 2D metal-organic framework (2D MOF) on oxidized carbon nanotube (CNT), is developed, which exhibits highly effective antimicrobial activity and eradicates Staphylococcus aureus infected rabbit tibia osteomyelitis under MV irradiation. This study represents a major advancement in antibiotic-free MV therapy for deep tissue bacterial infection.

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: Zn biodegradation induces a consistent, dose-dependent spatioteporal response in angiogenesis, both in vivo and in vitro. The concentration of degradation products tends to spread in a decreasing direction centered on the implant. Meanwhile, vasularization significantly increases at a distance of 100-200 mu m from the implant. Vascular endothelial cells show similar effects being affected by different doses of Zn extraction.
