In the present study, CdSe Nanoparticles (CdSe-NPs) were characterized using UV-vis (ultraviolet) and TEM (transmission electron microscope) and added to nonionic surfactant (NS) with different ratios (1, 2, 3 and 4 wt%) of to formulate CdSe-NS nanocomposite for caron steel (CS) corrosion control. The inhibition effect of the prepared inhibitor was investigated via electrochemical techniques such ...
