Selenium nanoparticles (SeNPs) were fabricated using a green microwave technique in the presence of ascorbic acid. The morphological features indicated that semi-spherical SeNPs with diameter 8.5–22 nm configured agglomerated spherical shapes diameters around 0.47–0.71 μm. Furthermore, removal Fuchsin Basic dye from aqueous solutions was investigated upon variation concentration SeNPs. degradation efficiency achieved 100% for 10 mg after 34 min visible light irradiation time. antioxidant...

Abstract The inhibition effect of dicyandiamide (DCDA) on the carbon steel (CS) corrosion in 0.5 M HCl solution was evaluated using chemical and electrochemical methods. maximum efficiency (%IE) optimal dose were 95.7% 0.30 mg/L DCDA inhibitor, respectively. temperature %IE is measured chemicals by gravimetric loss tests. Potentiodynamic polarization (PD‐P) tests clarified that a mixed‐type while EIS revealed charge transfer resistance ( R ct ) increased with inhibitor concentration. mixed...
Nonionic surfactants derived from phenol compounds inhibit the corrosion of carbon steel in 1.0 M HCl solution using galvanostatic polarization, electrochemical impedance spectroscopy, potentio-dynamic anodic polarization and weight loss techniques.
