Summary: In this study, Fe3O4 was functionalized through SiO2 coating to enhance dispersibility, chemical stability, and magnetic flocculation performance. Fe3O4/SiO2 demonstrated effective flocculation of kaolin particles, achieving high removal efficiency in turbid water. The interaction between Fe3O4/SiO2 and Ca2+ was found to play a crucial role in the flocculation process, with the energy barrier significantly reduced due to electrostatic interactions. The study also highlighted the importance of floc structures formed during magnetophoresis in influencing the flocculation of kaolin particles.

Summary: A novel PVDF-SiO2-Silane-based superhydrophobic (SHP) coating was fabricated, which showed enhanced corrosion resistance and self-cleaning properties. The coating had micro-nano hierarchical structures and contained Si, O, F, and C. The SHP carbon steel samples exhibited water contact angles > 170 degrees and a sliding angle close to 0 degrees. The SHP property remained unaffected after immersion in water and demonstrated good chemical repellence to acidic and basic solutions. The SHP samples also showed excellent self-cleaning property. Electrochemical impedance spectroscopy studies revealed that the charge transfer resistance of SHP samples was significantly higher compared to bare samples in aggressive chloride conditions.

Summary: The huge interest in superhydrophobic surfaces is due to their potential engineering applications in various fields. However, there is a challenge in fabricating mechanically robust superhydrophobic surfaces and understanding their corrosion performance in aggressive conditions. In this study, a simple and eco-friendly method was used to fabricate mechanically durable superhydrophobic aluminum surfaces with self-cleaning properties. The coating parameters were optimized to achieve desirable properties, and the adhesion between the substrate and the coating was improved. The superhydrophobic behavior was attributed to the hierarchical micro-nano roughness and the presence of specific chemical groups. The corrosion resistance of the superhydrophobic aluminum surfaces was significantly higher than that of bare surfaces. The results showed that the fabricated superhydrophobic surfaces had excellent properties for various applications, including seawater applications.

Summary: A numerical scheme is proposed for a priori generation of optical patterns for magnetic nanoemulsion (MNE) based defect detection in ferromagnetic steel specimens. The scheme involves the physical characterization of MNEs, obtaining surface distributions of magnetic flux leakage (MFL) using finite element modeling, and converting MFL distributions to lambda max values to generate optical patterns. Simulated images show good agreement with experimental images, validating the efficacy of the proposed scheme for defect detection. The scheme can also benefit the selection of appropriate MNE-based sensors and enhance detection capabilities.

The contrast of IC-AC-SECM imaging was found to be influenced by the perturbation frequency and bias potential applied to the Pt ultramicroelectrode (UME). The optimal parameters for high contrast imaging with high sensitivity were determined by potentiodynamic polarization and approach curves.
