“…This is due to the presence of Zn at a concentration of 38% in alloys, which decreases the stability in chloride solution when the two compounds are combined, and adsorption films are formed via heteroatoms and electrons, resulting in the production of a protective layer. 30 , 42 , 47 …”

“…Comparing PP, EIS, and EFM data to the data without the inhibitor, it is found that the two GSs were successful in inhibiting the corrosion. This is due to the presence of Zn at a concentration of 38% in alloys, which decreases the stability in chloride solution when the two compounds are combined, and adsorption films are formed via heteroatoms and electrons, resulting in the production of a protective layer. ,, …”

For a variety of applications, the brass alloy has been utilized to replace titanium tubes in heat exchangers. Copper alloys’ high corrosion rate during the acid cleaning procedure remains a significant concern. To inhibit the corrosion of brass alloys, we prepared two novel gemini surfactants (GSs), N 1 , N 3 -dibenzyl- N 1 , N 1 , N 3 , N 3 -tetramethylpropane-1,3-diaminium tetrafluoroborate (I H) and N 1 , N 1 , N 3 , N 3 -tetramethyl- N 1 , N 3 -bis (4-methyl benzyl) propane-1,3-diaminium tetrafluoroborate (I Me), and they were characterized using Fourier transform infrared spectroscopy and 1 H nuclear magnetic resonance spectroscopy. Their inhibition performance against corrosion of brass alloys in 1 M HCl was studied using electrochemical techniques including potentiodynamic polarization (PP), electrochemical impedance spectroscopy, and electrochemical frequency modulation. The inhibition effect of the synthesized compounds was high, and it increased as the inhibitor’s concentration was increased. The maximum level of inhibition efficiency was achieved at an inhibitor concentration of 100 ppm, reaching 96.42% according to PP measurements. From Langmuir data, the mechanisms of adsorption of the two GSs on the surface of copper was found to be physisorption and chemisorption adsorption. X-ray photoelectron spectroscopy and scanning electron microscopy show that the addition of the two compounds lowers the dissolution of brass ions in the corrosive solution and forms a protective layer on the surface of the brass.

“…As noted in our previous work, the used tools available were cited. [6,12,13] Corrosion experiments were executed according to the standard method ASTM G59-97(2014) by Gamry 3000 potentiostat/galvanostat/ZRA, and Echem Analyst 7 was consumed to clarify result. Electrochemical cell consists of AlSi, saturated calomel electrode (SCE), and a platinum wire where they consumed as working, reference, and counter electrodes, respectively.…”

The condensation reaction between 5‐amino‐1,3,4‐thiadiazole‐2‐thiol and 1,2‐dibromoethane to afford the ligand L was carried out in direct to obtain the desired organic ligand. New [Er(L)ClH2O]Cl2·3H2O, [Yb(L)(H2O)2]Cl3·4H2O, and [Ta(L)Cl2]Cl3·4H2O complexes have been prepared from (L) by reacting one mole from metal ions with one mole from L. In addition to their physical characteristics, they were described using spectroscopic techniques (infrared [IR], nuclear magnetic resonance [NMR], and UV–Vis), gas chromatography (GC)‐mass, and X‐ray powder diffraction. Further interpretation of complex structures was supported by measurements of molar conductivity, magnetic susceptibility, mole ratio, and thermodynamic investigations in addition to theoretical study through the use of density functional theory and characterization techniques. IR spectral data showed the mode of action of the neutral tetradentate L ligand and its coordination via two N‐amine and two S‐thiols. The octahedral geometry surrounding the central lanthanide ions was suggested by the magnetic moments, diffused reflectance, and spectral data. Molar conductivity results exposed that Yb(III) and Ta(V) chelates were 1:3 electrolytes and Er(III) chelate was 1:2 electrolyte. In addition, practically all the complexes demonstrated effective antimicrobial activity against Escherichia coli, Pseudomonas aeruginosa, Bacillus subtilis, and Staphylococcus aureus species, via inhibition zone diameters in 9–15 mm mg−1 range. However, neither Candida albicans nor Aspergillus flavus species were susceptible to their antifungal effects. Finally, molecular docking (MOE) experiments showed the significant binding affinity of the ligand and its complexes with several 6KOC, 6LU4, and 6LU4 protein receptors. Finally, it is important to emphasize that these complexes may be potential antioxidant agents according to the biochemical results. Electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) methods were accustomed to examine the corrosion inhibition of aluminum silicon alloys (AlSi) in 1 M HCl solution. Experimental measurements indicate that the thiadiazole ligand reduces the corrosion rate.

“…The anticorrosion and antibacterial activities of ionic liquidsbased on benzalkonium chloride derivatives (BCILs; N-benzyl-N, N-dimethyldodecan-1-aminium chloride: ILa, N,N-dimethyl-N-(4methylbenzyl)dodecan-1-aminium chloride: ILb, N-(4-chlorobenzyl)-N,N-dimethyldodecan-1-aminium chloride: ILc, and N,N-dimethyl-N-(4-nitrobenzyl)dodecan-1-aminium chloride: ILd) were examined for the carbon steel immersed in the contaminated solution by sulfatereducing bacteria [142]. The BCILs displayed high anticorrosive efficacy in contaminated solution by sulfate-reducing bacteria even at low concentration, due to the capability of BCILs to adsorb on the surface of carbon steel.…”
