Summary: A myristate coating containing Ca and Ce (Ca/Ce coating) was prepared on the surface of an anodized magnesium alloy by electrodeposition. The coatings exhibited superhydrophobicity and excellent corrosion resistance in 3.5 wt% NaCl solution. The concentration ratio of Ca2+ and Ce3+ in the electrolyte solution was found to affect the morphology, hydrophobicity, and corrosion properties of the Ca/Ce coatings. The introduction of Ce ions in the electrolyte solution enhanced the thickness and hydrophobicity of the coatings compared to the single Ca coating. An appropriate ratio of Ca2+ and Ce3+ was necessary for the Ca/Ce coating to provide durable and stable protection for magnesium alloy with rare cracks and high superhydrophobicity.

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.

Summary: In the study of BM-SCO and HSCO thin films, it was found that H vacancies tend to prefer sites near the external surface or oxygen vacancy channels (OVCs), while H interstitials prefer sites of oxygen on a layer that contains six-fold coordinated Co. These findings not only enrich the understanding of complex surface phenomena of defect formation but also provide an explanation for the reversibility during phase transformation.

Summary: In this study, a potential platform to enhance Raman scattering and increase the number of observable Raman modes in monolayer transition metal dichalcogenides (TMDs) was proposed. The platform consisted of large-scale arrays of gold micropillars (MPs), which were able to enhance the Raman intensity of TMDs and make difficult-to-detect Raman modes observable. The platform showed great industrial advantages and wide applicability due to its low cost, simple process, large controllable area, and short process time.
