Summary: The novel triphenyl imidazole based on 8-hydroxyquinoline (HDiPIQ) was found to be an effective inhibitor for mild steel corrosion in 1 M HCl solution, showing considerable inhibitive efficiency and mixed-type inhibitor properties. The adsorption of HDiPIQ on the steel surface followed Langmuir's isotherm model, predominantly through a chemical adsorption mechanism. However, the inhibiting efficiency was slightly affected by temperature.

Summary: The new green corrosion inhibitor STBim was synthesized in a single step reaction and showed high efficiency in inhibiting carbon steel corrosion in 15% HCl. Adsorption followed Langmuir isotherm, impedance measurements supported improved capacitive behavior, and potentiodynamic polarization studies revealed a mixed behavior with cathodic predominance. Computational studies showed that the inhibitor adsorbed mainly in the protonated form, resulting in a shift in the steel's work function.

Summary: Carbon steel is widely used in severe industrial conditions and is highly susceptible to corrosion. Traditional corrosion inhibitors, although effective, are toxic to humans and harmful to the environment. Ionic liquids, as a new alternative, have shown promising results as corrosion inhibitors for carbon steel in hydrochloric acid. This review presents recent advances in the application of ionic liquids for corrosion inhibition, with all results obtained from potentiodynamic polarization tests.

Summary: In this study, the anti-corrosion performance of 1-dodecyl-3-phenylquinoxalin-2(1H)-one (QO12) for carbon steel (CS) was evaluated using various techniques. The results showed that QO12 achieved a maximum inhibition performance of 95.33% at a concentration of 0.001 M. The study revealed that QO12 acted as a mixed-type inhibitor and the corrosion process of CS was dominated by a transfer-of-charge mechanism. The adsorption of quinoxalinone followed the Langmuir adsorption isotherm. SEM analysis showed no corrosion deterioration after the addition of QO12.

Summary: This study investigated the corrosion inhibitory and adsorption properties of two imidazole derivatives, TIMQ and CDIQ, on carbon steel in 1 M HCl solution. The results showed that both TIMQ and CDIQ were effective inhibitors with inhibition efficiencies of 94.8% and 95.8% respectively. The inhibitors acted as mixed-type inhibitors and improved the formation of a protective layer on the metal surface. Adsorption of the inhibitors onto the carbon steel surface was observed through Langmuir adsorption isotherm method. These findings can be useful in evaluating the effectiveness of inhibitors in HCl acid solutions.

Summary: The article highlights common pitfalls in the literature, including deductions based on isolated inhibitors, the limitations of quantum methods in accounting for environmental aggressiveness, distrust in interpreting small energy descriptor differences, and the use of simplistic surface models. The study focuses on local reactivity descriptors for the molecule 6-chloro-2-phenylimidazo[1,2-b]pyridazine, and highlights the importance of considering the corrosive medium's nature and concentration. DM and MC methods are used to account for inhibitor-metal interactions and the dynamic aspects of the adsorption process. The study reveals that the adsorption energy of CP-IPZH does not reflect the polarization resistance in different concentrations of HCl.

Summary: This study found that eucalyptus essential oil, due to its antioxidant constituents, provides benefits to the immune system. Additionally, the study discovered that the oil acts as a corrosion inhibitor, effectively protecting C38 steel in an acidic solution of HCl. Various techniques, including gravimetric and electrochemical measurements, scanning electron microscopy, and energy dispersive spectroscopy analysis, were used to confirm these findings. The results showed that the eucalyptus essential oil reduces the corrosion rate and acts as a mixed inhibitor. The impedance data revealed a higher charge transfer resistance with increasing concentration of the oil, reaching an efficiency of 80% at 2.4 g/L. Thermodynamic parameters indicated that the interaction between the oil and the metal surface is endothermic, involving physical adsorption.
