    Anti-corrosion Properties of 2-Phenyl-4(3H)-quinazolinone-Substituted Compounds: Electrochemical, Quantum Chemical, Monte Carlo, and Molecular Dynamic Simulation Investigation
    (Springer, 2020) Kacimi, Y. El; Touir, R.; Alaoui, K.; Kaya, S.; Abousalem, A. Salem; Ouakki, M.; Touhami, M. Ebn
    In this investigation, attempts have been made to study the corrosion inhibition properties of three new 2-phenyl-4(3H)-quinazolinone-substituted compounds for mild steel in 1.0 M hydrochloric acid medium. The evaluation was carried out using mass loss, electrochemical impedance spectroscopy, and polarization curves measurement. It is shown that 2-phenyl-4(3H)-quinazolinone-substituted compounds are very good inhibitor’s for mild steel corrosion in 1.0 M hydrochloric acid medium, which acts as mixed-type inhibitors. So, the inhibition efficiency was increased with inhibitor concentration in the order Q-p-Cl > Q-m-Cl > Q-H, which depends on their molecular structures and the chloride para/metapositions. Electrochemical impedance spectroscopy has shown that all compounds act by the formation of a protective film at the metal surface. The correspondence between inhibition property and molecular structure of the 2-phenyl-4(3H)-quinazolinone-substituted compounds is investigated, using density functional theory (DFT). The effect of molecular structure on the inhibition efficiency has been explored by quantum chemical computations and obvious correlations were observed. The binding energies of tested compounds on Fe(110) surfaces were calculated using molecular dynamics simulation. Experimental and DFT study was further supported by molecular dynamic (MD) simulations study. © 2020, Springer Nature Switzerland AG.

    Corrosion inhibition studies for mild steel in 5.0 M HCl by substituted phenyltetrazole
    (SPRINGER HEIDELBERG, 2017) El Kacimi, Y.; Azaroual, M. A.; Touir, R.; Galai, M.; Alaoui, K.; Sfaira, M.; Touhami, M. Ebn; Kaya, S.
    The inhibition efficiency of three substituted phenyltetrazole compounds, namely 5-(4-chlorophenyl)-1H-tetrazole (Cl-PT), 5-(4-methoxyphenyl)-1H-tetrazole (MO-PT), and 5-phenyl-1H-tetrazole (PT), for mild steel corrosion in 5.0 M HCl solution was investigated using weight loss measurements and electrochemical study. It is showed that these compounds are good inhibitors for mild steel corrosion in 5.0 M HCl solution which act as cathodic type inhibitors. So, the inhibition efficiency was increased with inhibitor concentration in the order of Cl-PT > MO-PT > PT which depended on their molecular structures. It is found also that these compounds toke its performance at different temperatures range from 298 to 328 K. In addition, the thermodynamic adsorption parameters at different concentrations were investigated and discussed. Finally, it is seen that the inhibition efficiency of the studied compounds increased with immersion time to reach a maximum at 12 h.

    New triazepine carboxylate derivatives: correlation between corrosion inhibition property and chemical structure
    (Springer Heidelberg, 2020) Alaoui, K.; El Kacimi, Y.; Galai, M.; Serrar, H.; Touir, R.; Kaya, S.; Kaya, C.
    In this investigation, attempts have been made to study the corrosion inhibition properties of three new triazepine carboxylate compounds for mild steel in 1.0 M hydrochloric acid medium. The evaluation was carried out using mass loss, electrochemical impedance spectroscopy and polarization curves measurement. Impedance diagrams and Bode plots for uninhibited and inhibited systems were analyzed using Zview program. The fitted data observed trails in nearly the same pattern as the experimental results. It is showed that triazepine carboxylate compounds are very good inhibitors for mild steel corrosion in 1.0 M hydrochloric acid medium which act as mixed-type inhibitors. So, the inhibition efficiency was increased with inhibitor concentration in the order Cl-Me-CN > Me-CN > Cl-Me-CO2Et which depended on their molecular structures. Electrochemical impedance spectroscopy showed that all compounds act by the formation of a protective film at the metal surface. Surface analyses via SEM and Optical 3D profilometry were used to investigate the morphology of the steels before and after immersion in 1.0 M HCl solution containing inhibitors. The correspondence between inhibition property and molecular structure of the triazepine carboxylate compounds was investigated, using density functional theory (DFT). Experimental and DFT study was further supported by molecular dynamic simulations study.

    Sustainable Management and Valorization of Food Waste
    (Springer Nature, 2024) Alaoui, K.; Rbaa, M.; Kacimi, Y. El; Tüzün, B.; Berdimurodov, E.
    Sustainable food management system’s needs, good food resources governance, food losses, and avoiding waste as much as possible. Although the advanced tools, equipments, and technologies available today, 30% of food produced for human being consumption is wasted, causing gigantic environmental troubles, economic loss, and food uncertainty issues. These occurrences and elevated volumes of food industry wastes attract several social, political, and scientific attention. Growing interest of social, political, and scientific has recently been focused on waste management, product valorization, and improve food waste and furthermore food security. Thus, the aim of this section is to analyze the current status, emerging challenges, and prospects of food wastes, waste management, and their effects on sustainability of food production are presented and discussed. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2024.
