Summary: Carboxamide derivatives were synthesized and studied for their corrosion mitigation effect on mild steel in hydrochloric acid. The experimental results showed that these derivatives exhibited efficient anti-corrosion properties, with the level of corrosion inhibition proportional to their concentration. Electrochemical techniques revealed their mixed-type inhibition mechanism with single charge transfer at the metal-electrolyte interface. The structural and electronic characteristics of the inhibitors were found to have an impact on the corrosion process.

Summary: A thick cementite skeleton exposed on a ferritic-pearlitic C1018 steel surface significantly reduced inhibition efficiency after pre-corrosion, while this effect was insignificant for a lower carbon X65 steel with dispersed cementite microstructure, as only a small amount of cementite remained on its surface after pre-corrosion. Normalizing the increased cathodic area in the presence of residual cementite back to the original area inhibited both anodic and cathodic reactions to the same extent as on bare steel with a sufficient inhibitor concentration. However, the detrimental effect of cementite cannot be completely eliminated due to its galvanic coupling effect.

Summary: Green biopolymeric materials and their hybrid nanocomposites were investigated for corrosion prevention of mild steel in 15% HCl. The results showed that the SA-g-PMMA/TiO2 exhibited the highest inhibition efficiency of 97.28%, followed by SA-g-PMMA/Fe3O4 with 96.82% efficiency, while unmodified sodium alginate only showed 84.74% efficiency. The inhibition efficiency decreased with increasing temperature, and the inhibitors followed Langmuir adsorption isotherm. The nanocomposites formed a better protective adsorption layer on the exposed metallic surface compared to sodium alginate alone, as observed from FE-SEM and AFM analysis. The elemental composition of the adsorbed film was determined using XPS technique. Density Functional Theory (DFT) results supported the experimental outcomes.

Summary: The corrosion performance of mild steel in 1M HCl solution was investigated in the presence of a green corrosion inhibitor called nonanedihydrazide. The inhibitor showed high adsorption on the steel surface and acted as a mixed inhibitor. The corrosion inhibition efficiency increased with an increase in the inhibitor concentration and decreased with an increase in temperature. Theoretical computations using density functional theory supported the experimental findings and provided insights into the inhibitive mechanism of nonanedihydrazide.

Summary: This work demonstrates how the current phase transition of atomic Bose-Einstein condensates in a trap can be controlled by applying an oscillatory driving field. The self-trapping effect in momentum space allows for a suppression of oscillations and a nearly constant directed current. Mean-field chaos serves as an indicator of the quantum phase transition. These findings are supported by an effective three-mode model.
