“…In the context of corrosion mitigation, CA measurements offer insights into the emergence of a hydrophobic defensive layer upon the surface of mild steel. A contact angle goniometer was utilized in this research to measure the contact angle formed between the corrosive solution and the metallic surface ( Andrés Coy-Barrera et al, 2023 ; Yadav et al, 2023a ; Martinović et al, 2023 ). The contact angle is impacted by the interfacial forces between the liquid, solid, and gas phases, and a higher contact angle indicates a less wettable surface.…”

“…To combat corrosion, the development of corrosion inhibitors has gained significant attention globally. Organic compounds, including drug molecules, have evolved as viable corrosion inhibitors due to their varied chemical structures and potential for adsorption onto metal surfaces ( Andrés Coy-Barrera et al, 2023 ; Njoku et al, 2023a ; Nie et al, 2023a ). This approach has been explored in various regions.…”

The deterioration of mild steel in an acidic environment poses a significant challenge in various industries. The emergence of effective corrosion inhibitors has drawn attention to studies aimed at reducing the harmful consequences of corrosion. In this study, the corrosion inhibition efficiency of Prinivil in a 1M HCl solution through various electrochemical and gravimetric techniques has been investigated for the first time. The results demonstrated that the inhibition efficiency of Prinivil expanded from 61.37% at 50 ppm to 97.35% at 500 ppm concentration at 298 K. With a regression coefficient (R2) of 0.987, Kads value of 0.935 and Ea value of 43.024 kJ/mol at 500 ppm concentration of inhibitor, a strong affinity of Prinivil for adsorption onto the metal surface has been significantly found. Scanning electron microscopy (SEM) and contact angle measurement analyses further support the inhibitory behavior of Prinivil, demonstrating the production of a defensive layer on the surface of mild steel. Additionally, molecular dynamics (MD) and Monte Carlo simulations were employed to investigate the stability and interactions between Prinivil and the metallic surface (Fe (1 1 0)) at the atomic level. The computed results reveal strong adsorption of Prinivil upon the steel surface, confirming its viability as a corrosion inhibitor.

“…Chalcones have demonstrated various biological activities including antioxidants, [3][4][5] anticancer, [6][7][8] antidiabetic, [9][10][11] antiviral, [12][13][14] antimalarial, [15][16][17] and many more. Aside the biological properties of chalcones, they have been employed in chemical industries as fluorescent active materials, [18][19][20] corrosion inhibitors, [21][22][23][24] and in the synthesis of liquid crystals. [25][26][27][28] Some reported metal complexes of chalcones also exhibit antihyperglycemic and antimicrobial activities.…”

The growing interest in synthesizing electrochemically active organic ligands stems from extensive reports highlighting the applications of redox‐active organic molecules. These molecules play a crucial role in capturing and converting CO2 into valuable organic compounds, including carbonates used as solvents in lithium batteries. In this study, we present an electrochemical investigation of two chalcone derivatives, referred to as (1) and (2). We explored the influence of different solvent systems, specifically acetonitrile and dimethyl sulfoxide, on the reduction potential of these chalcones. The reported chalcone derivatives were characterized using various analytical techniques, including UV/Visible spectroscopy, Fourier Transform Infrared spectroscopy, Proton and Carbon‐13 nuclear magnetic resonance, as well as mass spectrometry. The characterization of the reported chalcones, exhibiting properties of both β‐diketones and 2‐hydroxyphenones, is underscored by a density functional theory (DFT) study of chalcones (1) and (2). This research establishes a correlation between the energies calculated through DFT and the experimental reduction potentials of chalcones (1) and (2), in comparing them with a series of β‐diketones and 2‐hydroxyphenones.
