Summary: With increasing awareness of the environment and food safety, the development of biodegradable active food packaging has gained attention in recent years. Starch is considered a potential bio-material for producing biodegradable films. However, the functional performance of starch-based films is limited, hindering their application as food packaging materials. In this study, a simple green method was developed to improve the dispersibility of graphene in starch-based films. The addition of nanocomposites positively influenced the microstructure, mechanical properties, barrier properties, and thermal properties of the films. Additionally, the composite films exhibited antibacterial activity, showing their promising potential as active food packaging.

Summary: To overcome the low bactericidal activity and poor osteogenic activity of titanium in dental implants, researchers surface-modify biomedical titanium through the plasma immersion coimplantation of magnesium and copper ions. The best-performing Mg/Cu(8/10)-Ti sample promotes cell proliferation and initial cell adhesion, exhibits high hydrophilicity, outstanding activity against periimplantitis-causing bacteria, and shows good bio-/hemocompatibility. This study concludes that Mg/Cu coimplantation endows the titanium surface with high bacteriostatic activity and biocompatibility, which could pave the way for widespread use of titanium-based dental implants.

Summary: This study synthesized succinylated chitosan (SCS)-based hydrogels with high decomposition rate and excellent biocompatibility, confirming well distributed Bone Graft Materials (BGMs) inside the SCS hydrogel. Increasing succinylation rate in SCS-B hydrogels led to a decrease in mechanical properties, such as compressive strength and Young's modulus, while also exhibiting high cell growth rate and bone differentiation rate. In vivo results showed that the SCS hydrogel could resorb into surrounding tissues while maintaining BGMs in the transplantation area for up to 6 weeks, indicating potential as a bioactive drug carrier for various biomedical applications.

Summary: The corrosion behavior of Fe-60 and Fe-83 ribbons in 0.6 M NaCl was studied. Fe-60 exhibited a local corrosion mode and formed a stable passivation film with higher corrosion resistance, while Fe-83 showed a combination of local and global corrosion modes and had lower corrosion resistance. Controlling the precipitation of nanocrystalline phases and increasing the POx content in the passivation film significantly improved the corrosion resistance of Fe-based glassy alloys.
