Summary: A postgrafting strategy mediated by polydopamine (PDA) coating is proposed to incorporate different metal elements into mesoporous silicate bioactive glass nanoparticles (MBG NPs) while maintaining their stability. However, the PDA coating reduces the ion-binding free energy of MBG NPs for calcium and phosphate ions, resulting in minimal deposition of calcium phosphate clusters on the PDA@MBG NP surface after immersion in simulated body fluid for 7 days, indicating a lack of hydroxyapatite mineralization.

Summary: Raman spectroscopy revealed key mutations and structural differences in the molecular structure of the SARS-CoV-2 Delta variant compared to the Kappa variant. The hydrolytic reactions on the surface of silicon nitride bioceramics induced instantaneous inactivation of both variants. Contact with the bioceramics also led to post-translational modifications of spike residues and oxidation of RNA purines. Si3N4 bioceramics proved to be a safe and effective material for environmental sanitation.

Summary: In this study, Raman and X-ray photoelectron spectroscopies were used to analyze the compositional and structural variations of activated carbon (AC) generated from different carbonate sources in three types of systems, PVDF/M2CO3 (M = Li, Na, and K). The results show that the structure of AC strongly depends on the type and content of the initial carbonate, which is determined by practical dehydrofluorination reactions and oxygen incorporation in AC. This study provides insights into the PVDF dehydrofluorination process and the formation of activated carbon, contributing to optimizing the material performance of percolative composites for flexible energy storage applications.

Summary: The use of silicon nitride (Si3N4) ceramics as bioactive structural materials has become popular due to their ability to stimulate cell proliferation and fight pathogens. However, the brittleness and high production costs of silicon nitride limit its applications. This study investigates the addition of Si3N4 particles to Poly(methyl met-achylate) (PMMA) bone cements to examine their impact on mechanical and antibacterial properties. The results show that the antibacterial effects of Si3N4 increase with the ceramic fraction and decrease with the mesh size of the powders. Additionally, smaller particles at lower concentrations act as a mechanical reinforcement, increasing the composite's ultimate tensile strength by approximately 10%.

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.
