Summary: A novel anti-corrosion composite coating, which combines micro-arc oxidation (MAO), ionic liquid, and superhydrophobic coating, is fabricated for magnesium alloys. The successful preparation of the composite coating is characterized by various techniques, and its excellent anti-corrosion performance is attributed to the synergistic effect of the superhydrophobic feature, the corrosion inhibition of the ionic liquid, and the physical barrier of the MAO coating. The incorporation of the ionic liquid not only offers self-healing capability but also enhances the overall anti-corrosion performance of the composite coating by sealing the pores on the MAO surface.

Summary: This study synthesized biochar based on sapropel and investigated the effects of chemical modification on its textural characteristics, acid-base properties, and adsorption properties. The results showed that the chemical modification increased the fraction of micropores, specific surface area, and changed the surface properties of biochar. The experiment also revealed that biochar pretreated with alkali exhibited the maximum adsorption capacity for copper ions. A conceptual model identifying the mechanisms of copper adsorption on sapropel-based biosorbent was proposed.

Summary: The corrosion inhibitory potency of two new pyrimidine-pyrazole derivatives, PPA and PPC, was evaluated for mild steel in 1 M HCl. The results showed enhanced inhibition activities with increased concentration, reaching maximal values of 91.15% and 92.39% for PPA and PPC, respectively. However, the mitigation potency decreased with increasing temperature. SEM and XPS analysis revealed that PPA and PPC adsorbed on the mild steel surface, forming a shielding layer that prevented the dissolution of the steel in the acidic solution.
