Research paper (pdf)_ electrochemical and molecular dynamics simulation studies on the corrosion inhibition of aluminum in molar hydrochloric acid using some imidazole derivatives

The corrosion inhibition and adsorption characteristics of three selected imidazole derivatives namely, 2-amino-4,5-imidazoledicarbonitril

(AID), 5-amino-4-imidazolecarboxamide (AIC) and imidazole (IM) on aluminum in 1.0M HCl was investigated at 25°C. Weight loss team names Measurements

were carried out under various experimental conditions using chemical (weight loss), and electrochemical (Tafel polarization

and impedance) methods. 5 day diet plan Molecular dynamics (MD) method and density functional theory were also applied here for theoretical

study. Lose belly fat overnight wrap Results obtained showed that inhibition efficiency of these compounds increases with increase in their concentrations

due to the formation of a surface film on the aluminum surface.

Paleo egg muffins Adsorption energy as well as hydrogen bond length calculations

showed that AID was the best corrosion inhibitor among the tested imidazole derivatives. Losing weight on birth control Polarization measurements reveal

that the selected imidazole derivatives function mainly as cathodic-type inhibitors. Paleo banana bread with almond flour Physisorption, followed by chemisorption

was proposed as the mechanism for the inhibition process. Protein s deficiency diet Adsorption via H-bond formation was also considered here. Exercise tv Results

obtained from theoretical study were found to confirm experimental findings.

Correlating electronic structure with corrosion inhibition potentialityof some bis-benzimidazole derivatives for mild steel in hydrochloricacid: Combined experimental and theoretical studies

• “For BBE, as two BI groups are not in same plane, only one BI group should preferentially adsorb on metal surface. Protein diet chart for weight loss Such mechanism for adsorption depending on the stereochemical conformation of BI and its derivatives (parallel or perpendicular orientation) have been reported by many authors [15,42,53].

[Show abstract] [Hide abstract] ABSTRACT: Four different bis-benzimidazole (BBI) derivatives, tested as potential corrosion inhibitors for mild steel in 1 M HCl, have revealed good inhibition efficiency for long period of exposure. Paleo chocolate chip cookies Inhibitors impart high resistance towards charge transfer across metal–electrolyte interface and behave broadly as mixed type. Losing weight in your 40s DFT calculations are used to correlate inhibition potentiality with intrinsic molecular parameters. Benefits of healthy diet From the optimized geometry of BBI derivatives, electron distribution in HOMO and LUMO and Fukui indices ofeach atom, possible modes of interaction of BBI derivatives with mild steel surface have been predicted.Energy corresponding to inhibitor-metal surface interaction is evaluated following molecular dynamics simulation.

[Show abstract] [Hide abstract] ABSTRACT: The inhibitive action of 4-methyl pyrazole (4MP) against the corrosion of iron (99.9999%) in solutions of hydrochloric acid has been studied using potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Low carb diet shopping list At inhibitor concentration range (10?3–10?2 M) in 1.0M acid, the results showed that 4MP suppressed mainly the anodic processes of iron corrosion in 1.0M HCl by adsorption on the iron surface according to Temkin adsorption isotherm. Exercise addiction Both potentiodynamic and EIS measurements reveal that 4MP inhibits the iron corrosion in 1.0M HCl and that the efficiency increases with increasing inhibitor concentration. Low carb diet vegetarian Data obtained from EIS were analyzed to model the corrosion inhibition process through an equivalent circuit.

[Show abstract] [Hide abstract] ABSTRACT: The inhibitive action of some benzimidazole derivatives namely 2-(2-furanyl)-1H-benzimidazole (FB), 2-(2-pyridyl) benzimidazole (PB) and 2-(4-thiazolyl) benzimidazole (TB), against the corrosion of iron in solutions of nitric acid has been studied using density function theory calculations (DFT), weight loss, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). Exercise induced urticaria cure The calculated electronic parameters involved in the activity of the benzimidazole derivatives confirmed that the position of the side chain in the benzimidazole moiety affects the pattern of activity. Exercise and diet The effectiveness of the benzimidazole derivatives is following the order TB>PB>FB. I want to lose weight but i love eating The same order is supported by the experimental chemical and electrochemical measurements. Healthy diet tips to lose weight The relationships between inhibition efficiency of iron in 1.0M HNO3 and the molecular orbitals of the studied molecules as well as number of electrons transferred ?N from the inhibitor molecules to the iron surface were calculated by DFT method. 6 week diet plan The inhibition efficiency increased with the increase in EHOMO and decrease in ELUMO–EHOMO. Weight loss icd 10 TB had the highest inhibition efficiency because it had the highest HOMO energy and ?N values, and it was most capable of offering electrons. Type c weight loss Molecular modeling was used to evaluate the structural, electronic and reactivity parameters of the selected benzimidazole derivatives in relation to their effectiveness as corrosion inhibitors. Paleo diet appetizers Results obtained from weight loss, dc polarization and ac impedance measurements are in reasonably good agreement and show increased inhibitor efficiency with increasing inhibitor concentration.Data obtained from EIS were analyzed to model the corrosion inhibition process through equivalent circuit.
