Summary: A one-step hydrothermal processing using a stearic-acid-based precursor medium was developed to produce super-hydrophobic and corrosion-resistant coatings for magnesium-lithium alloys. The coatings were formed through hydrothermal conversion and the concurrent formation of low surface energy materials. The obtained coating exhibited super-hydrophobicity and excellent corrosion resistance due to the multiscale microstructures and through-thickness stearates.

Summary: In this paper, the effect and mechanism of nanosecond pulse laser cleaning on the anodic oxide film on the surface of 7075 aluminum alloy were studied. The effects of different laser energy densities on the surface morphology, composition, roughness, microhardness, and contact angle of the 7075 aluminum alloy were investigated. The results showed that laser cleaning can effectively remove the anodic oxide film on the surface of the 7075 aluminum alloy and the new surface formed after laser cleaning is undamaged. Compared with mechanical removal methods, laser cleaning can improve the microhardness and hydrophobicity of the surface, providing feasibility for regular use after laser cleaning.

Summary: The corrosion resistance of architectural aluminum used in construction and finishing elements may be affected by the external environment and mechanical loads. However, current corrosion resistance tests do not adequately simulate the working environment and physical loads of the final product. Research findings show that temperature above 60°C can greatly impact the properties of EN AW-6063 aluminum alloy, while mechanical deformation does not affect the anti-corrosion performance of anodized aluminum alloy.

Summary: The study identified the constituent particles of AA2024-T3 Al alloys and detailed their microstructural change after alkaline degreasing, acidic desmutting, and zirconium (Zr) conversion coating. The constituent particles included Al-Cu-Fe-Mn, & theta;-Al2Cu, and S-Al2CuMg, and were several micrometers in size. The pretreatment enhanced the cathodic kinetics and reactivity of the conversion coating, while the subsequent Zr conversion coating inhibited anodic kinetics.

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: This study investigates the effects of high energy/fluence proton radiation on the performance of HfZrOx-based FeFETs memory with different Zr content. The results show that the characteristics of FeFETs are influenced by proton radiation, and the extent of the influence depends on the Zr content. FeFETs with 50% Zr content exhibit minimal changes in memory window and demonstrate good endurance and retention performance.

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.
