ABSTRACT Two novel multifunctional complexes [M(CCAM) 2 (NO 3 )](NO ) ·C H 5 OH (M = Dy (III)/Er (III); CCAM 2‐cyano‐ N ′‐((4‐oxo‐4H‐chromen‐3‐yl)methylene)acetohydrazide) were synthesized and characterized via elemental thermal analyses, molar conductivity, UV–vis., FT‐IR spectroscopy, revealing a 1:2 metal‐to‐ligand stoichiometry. The ligand coordinated with Dy(III) or Er(III) ions through nitrogen of azomethine oxygen the carbonyl γ‐pyran groups. Corrosion inhibition studies for Dy(CCAM), Er(CCAM), on carbon steel (C‐steel) in 1‐M HCl showed Dy(CCAM) Er(CCAM) as highly efficient, offering best protection. In solution, Fe 2+ at C‐steel surface interacts CCAM, compounds, demonstrated by UV–vis spectroscopy. At concentration 10 −3 M, compounds greater performance efficiency weight loss test reaching 93.34% 95.67%, respectively. Langmuir adsorption isotherm pronounced mixed mechanisms. characteristics SEM, EDX, AFM, contact angle measurements confirmed shielding. vitro antibacterial antifungal activity prepared against organisms, including Escherichia coli , Pseudomonas aeruginosa Staphylococcus aureus Bacillus subtilis bacteria, C andida albicans A spergillus fumigatus fungi is carried out. inhibitor exhibits greatest action different tested antimicrobials. Additionally, cytotoxicity produced growth inhibitory effects Erlish Acities Carcinoma was ascertained. found to have cytotoxic levels (IC 50 64 65 μM), As result, more effective therapeutic approach creation antimicrobial antitumor agents. For superior corrosion protection, theoretical molecular docking DFT MD simulations validated experimental results.

A confirmatory study on the use of N-methyl-2-pyrrolidone (NMP) in the industrial field for cleaning metal molds and other objects, Corrosion Inhibition of C38 Carbon Steel In 1M HCl: Experimental and Theoretical Study

Research Square (Research Square), Год журнала: 2025, Номер unknown

Опубликована: Март 25, 2025

This study presents a comprehensive investigation of N-methyl-2-pyrrolidone (NMP) as corrosion inhibitor for carbon steel (C38) in 1.0 M HCl environment, using both theoretical and experimental approaches. To the best our knowledge, this is first time NMP has been studied its anticorrosive properties. Electrochemical tests, conducted with an SP150 potentiostat three-electrode system, revealed that effectively inhibits through cathodic protection. The adsorption onto surface follows Langmuir isotherm model, confirmed by stationary transient studies. results showed significant increase polarization resistance, maximum inhibition efficiency 76.82% at concentration 10⁻² M. Theoretical analysis Density Functional Theory (DFT) indicated substantial energy gap (Egap = 6.293 eV) between highest occupied molecular orbital (HOMO) lowest unoccupied (LUMO), validating findings. Molecular dynamics (MD) simulations further demonstrated stable on surface, -606.103 kcal/mol. Additionally, Natural Bond Orbitals (NBO) provided insights into interactions bonding characteristics. Overall, these confirm effective steel, offering valuable mechanism potential industrial applications.
