Summary: Nitrogen-coordinated single-atom catalysts have emerged as a new frontier in accelerating the oxygen reduction reaction due to their optimal atom efficiency and properties. By constructing petal-like porous carbon nanosheets with densely accessible Fe-N-4 moieties, a catalyst with enhanced mesoporosity and balanced hydrophobicity/hydrophilicity was developed, leading to efficient utilization of active sites and superior performance in a broad pH range. When utilized in Zn-air battery and microbial fuel cell, the FeNC-D-based device displayed high power density and remarkable stability, outperforming the commercial Pt/C catalyst.

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: 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: 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: Unlike common injuries, deep burns often require a long recovery period and long-term antibiotic treatment to prevent infection. The emergence of drug-resistant bacteria has made antibiotics no longer perfect, and continuous drug use can easily result in recurring infections and even death. Inspired by wild animals that chew plants to prevent wound infections, researchers have extracted probiotic extracts from Lactobacillus casei with a structure similar to the tailspike of phage, and combined them with different flavones to design a series of nonantibiotic bactericides. These novel antibacterial agents, combined with a rapid gelation spray with a novel cross-angle layout, form an instant protection spray (IPS) that provides a physical and anti-infectious barrier for burns within 30 seconds.

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.

Summary: The microstructure, mechanical properties, and degradation rates of LX11 and LX41 alloys were studied through optical microscopy, tensile tests, and electrochemical tests. The LX11 alloy exhibited finer grains, fewer twins, and smaller intermetallic phase volume fractions compared to the LX41 alloy. Increasing Li concentration resulted in a slight decrease in yield strength, a substantial increase in elongation, and a stable ultimate tensile strength for the Mg-Li-Ca alloys. LX11 alloy showed superior corrosion resistance compared to LX41 alloy. The release rate of metallic ions in Hank's solution cannot accurately reflect the corrosion rate of Mg-Li-Ca alloys due to the formation of corrosion products and their solubility difference.

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.
