Summary: This paper describes the preparation and study of new bifunctional samples (Y(0.9)Ln(0.1)VO(4)/Fe3O4)@SiO2 and [(Y(0.9)Ln(0.1)VO(4)@SiO2)/ Fe3O4@SiO2] with Ln = Nd or Tb. The influence of Fe3O4 content and silica coating on the Y(0.9)Ln(0.1)VO(4)@SiO2 samples is analyzed, and their potential utility is determined. These samples, which have potential applications in biomedicine, can be directed using an external magnetic field and allow the visualization of diseased cells. The experimental and theoretical studies provide insights into the structural and vibrational properties of the samples, confirming the presence of silica coating. The [(Y(0.9)Ln(0.1)VO(4)@SiO2)/Fe3O4@SiO2] samples show the most suitable properties for use as bifunctional materials.

Summary: This study proposes a novel approach to reduce the viscosity of bitumen by using ionic surfactants at elevated upgrading temperatures. The results demonstrate that the cationic surfactant DTAB is the most effective, reducing the bitumen viscosity by 60% with only 0.25 wt% addition. Moreover, the addition of DTAB enhances the contents of saturates and aromatics, and alters the nanostructural properties of the bitumen's asphaltene.

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.
