Summary: This study evaluated the corrosion-inhibition efficacy of two 1,3,4-oxadiazole derivatives, POX and 4-PMOX, against mild steel corrosion in 1 N HCl. The evaluation was conducted using weight loss, Electrochemical Impedance Spectroscopy (EIS), Potentiodynamic Polarization (PDP), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray (EDX), UV-Vis spectroscopy, and theoretical analysis. Both POX and 4-PMOX showed excellent inhibition efficiency, with values reaching 97.83% and 98% at 500 ppm, respectively. The findings of this study provide valuable insights for the design of more efficient organic inhibitors for metal corrosion.

Summary: This study introduced the environmentally benign ingredient DEAE into the FFA formulation based on unsaturated diamine, showing excellent corrosion inhibition effect in acidic environment. The results indicated that DEAE facilitated the adsorption of NOPDA onto carbon steel surface, with adsorption mechanisms involving chemisorption, electrostatic attraction, and hydrogen bonding. The protective film formed on the surface of carbon steel was found to prevent the transfer of charge, providing a good reference for the application of unsaturated fatty diamine.

Summary: Green corrosion inhibitors, such as Citrus limetta peel extract, have gained attention for their cost-effectiveness, biodegradability, and eco-friendly characteristics in inhibiting the corrosion of metallic alloys. This study investigates the corrosion inhibition efficiency of Citrus limetta peel extract on mild steel surfaces in an acidic environment using electrochemical methods. The results demonstrate that the extract exhibits a corrosion inhibition efficiency of 93% on mild steel surfaces in hydrochloric acid media. The adsorption mechanism of the peel extract on mild steel surfaces involves both physisorption and chemisorption.

Summary: This article explores the synergy in corrosion inhibition and how to quantify it effectively. The equation for the synergistic parameter evaluates the inhibition efficiency of a mixture against a threshold based on the performance of pure compounds. However, the choice for the threshold value is not unique. The paper presents several reasonable alternatives, including using the Langmuir adsorption model, requiring the mixture's inhibition efficiency to be higher than the highest efficiency of pure compounds, or having a higher corrosion resistance in the mixture compared to the sum of resistances in pure compounds. The synergistic models are also extended to multi-component mixtures.

Summary: In this study, beta-cyclodextrin grafted polyacrylamide was synthesized and demonstrated to effectively inhibit the corrosion of X80 steel in sulfuric acid solution. The inhibiting performance was attributed to the adsorption films formed by beta-CD-PAM, following Langmuir adsorption isotherm, and its role as a mixed type corrosion inhibitor. Therefore, beta-CD-PAM is considered as a potential green corrosion inhibitor for oil and gas production.

Summary: In this study, effective Gemini cationic surfactants (CSII, CSIV) were synthesized and characterized. The adsorptive properties of CSII and CSIV at HCl/air and C-steel/HCl interfaces were investigated using surface tension and electrochemical parameters. The results showed that CSII and CSIV have high adsorption affinity at the HCl/air interface, with aliphatic chains promoting surfactant adsorption. Electrochemical impedance spectroscopy and potentiodynamic polarization revealed that CSII and CSIV act as mixed inhibitors, significantly enhancing the charge transfer resistance of C-steel in HCl. Theoretical calculations and simulations supported the experimental findings, demonstrating the relationship between corrosion inhibition and molecular structure.

Summary: This study investigated the adsorption and inhibitory effect of Rheum ribes (RR) root extracts on mild steel (MS) corrosion in 1 M HCl solution using electrochemical techniques. The surface characteristics of the electrode after exposure to corrosive solutions were analyzed using scanning electron microscopy (SEM) and atomic force microscopy (AFM), while the chemical composition and distribution of the surface film were examined using energy dispersive X-ray spectroscopy (EDX). The hydrophilic or hydrophobic properties of the MS surface were determined using contact angle (CA) measurements. The study found that RR root extract molecules adsorb to the metal surface, forming a protective and uniform film. Increasing the concentration of RR root extract enhances the resistance of the alloy surface to corrosion. The extract acts as a mixed-type corrosion inhibitor with cathodic dominance and shows a predominance of anodic reaction in the presence of iodide ions. Physical interactions play a crucial role in the adsorption of extract molecules. The synergistic effect between iodide ions and extract molecules improves the protective ability and stability of the film. The film formed by the extract molecules on the steel surface reduces surface deterioration and increases hydrophobicity.

Summary: Carbon steel is widely used in various industries, and its corrosion is a major concern. Carbon dots (CDs), especially heteroatom-doped CDs, have been developed as green corrosion inhibitors. A study compared the corrosion inhibition efficiency and mechanisms of nitrogen-doped and nitrogen, sulfur codoped CDs. The results showed that both types of CDs can effectively restrain the corrosion of carbon steel, with the codoped CDs exhibiting higher inhibition performance. Molecular dynamics simulation revealed the strong interaction between the codoped CDs and the carbon steel substrate, which contributes to the superior corrosion inhibition.
