“…Hardness (η) and softness(σ) are important parameters that help predict corrosion inhibitors’ adsorption affinity. As reported, a highly reactive molecule (soft) has a lower Δ E value and vice versa for the lower reactive one (hard) . Compound 4 has lower η values than compound 3 in the different studied forms.…”

The inhibitory impact of the two synthesized pyrazole derivatives (3 and 4) toward metallic and microbial corrosion was investigated. Using open circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy, it was possible to determine their ability to prevent the corrosion of C-steel in 1 M HCl, which was significantly enhanced with increasing concentration (ex. 93%). They act as mixed-type inhibitors, according to polarization curves. The compounds under investigation were adsorbed on a C-steel surface in 1 M HCl following the Langmuir isotherm model. The double-layer capacitance was decreased, and the charge transfer resistance (R ct) was raised due to the examined inhibitors’ adsorption. Investigating changes in the surface morphology and confirming the corrosion inhibition mechanism are done using scanning electron microscopy. Density functional theory calculations and Monte Carlo simulations were also conducted to show the adsorption affinity of the understudied compounds over the steel substrate in neutral and protonated forms. Furthermore, the antimicrobial performance of the two synthesized pyrazoles against sulfate-reducing bacteria was evaluated, and the recorded inhibition efficiency was 100%. The current research shows important developments in producing highly effective anticorrosion and antimicrobial pyrazole derivatives.

“…The polarization resistance ( R p ) values increase with the rise in inhibitor concentrations, leading to an increase in the number of adsorbed molecules. This suggests that these extracts are effective inhibitors [46,47] . As the concentration increases, more molecules from the extracts ( OgW and OgE ) accumulate on mild steel, significantly restricting the corrosion process.…”

“…This suggests that these extracts are effective inhibitors. [46,47] As the concentration increases, more molecules from the extracts (OgW and OgE) accumulate on mild steel, significantly restricting the corrosion process. At a concentration of 400 mg/L of the tested extracts, the polarization resistance R p was 71.4 Ω cm 2 and 139.5 Ω cm 2 , respectively.…”

Two green inhibitors extracted from an endemic species (Origanum grosii (Og)) using two solvents of different polarity (water and ethanol), OgW (aqueous extract) and OgE (ethanolic extract), were used for the anticorrosion of mild steel (M steel) in a 1M HCl medium. Anticorrosive performance of OgW and OgE was assessed using electrochemical techniques, weight loss method and SEM/EDX surface analysis. The results show that OgW achieves a maximum inhibition efficiency of 92% and that the extract in aqueous medium is more efficient than the extract in ethanolic medium (less polar). Both extracts act as mixed inhibitors and their corrosion process is predominantly governed by charge transfer. Concentration and temperature effect was studied and shown that they are two antagonistic parameters for the evolution of inhibitory effectiveness of OgW and OgE. The adsorption isotherms of the two inhibitors OgE and OgW obey to the Langmuir adsorption model. Moreover, the examination of SEM and EDX support a deposit of both extracts on metal surface by an adsorption phenomenon. Besides, theoretical approach of the molecular structures of the major compounds M‐OgW and M‐OgE and inhibition efficiency was examined via DFT calculations and molecular dynamics simulations and it was consistent with the experimental findings.

“…However, despite their considerable potential, there remains a lack of comprehensive reports on using surfactants for corrosion prevention across various electrolytes, waranting further exploration in this promising domain. The latest research has been conducted on the inhibition potential of novel cationic Gemini surfactants, [722][723][724][725] zwitterionic surfactants, 726 tera-cationic surfactants, 727 and Quaternium-22 728 for metallic materials in different media using different advanced testing techniques.…”
