A Study of the Synthesis and Characterization of New Acrylamide Derivatives for Use as Corrosion Inhibitors in Nitric Acid Solutions of Copper.

The objective of this research was to explore the impact of corrosion inhibition of some synthetic acrylamide derivatives 2-cyano--(4-hydroxyphenyl)-3-(4-methoxyphenyl)acrylamide (ACR-2) and 2-cyano--(4-hydroxyphenyl)-3-phenylacrylamide (ACR-3) on copper in 1.0 M nitric acid solution using chemical and electrochemical methods, including mass loss as a chemical method and electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization (PP) as electrochemical methods. By Fourier-transform infrared spectroscopy (FTIR), proton nuclear magnetic resonance (1HNMR), and mass spectroscopy (MS) methods, the two compounds were verified and characterized.

Phytosynthesis of CoO Nanoparticles as the High Energy Storage Material of an Activated Carbon/CoO Symmetric Supercapacitor Device with Excellent Cyclic Stability Based on a NaSO Aqueous Electrolyte.

The benign preparation of cobalt oxide nanoparticles (CoO-NPs) was performed using marine red algae extract () as a simple, cost-effective, scalable, and one-pot hydrothermal technique. The nominated extract was employed as an environmental reductant and stabilizing agent. The resultant product showed the typical peak of CoO-NPs around 400 nm wavelength as ascertained by UV-vis spectroscopy.
