An examination of the effectiveness of the expired drug isoprinosine in preventing aluminum corrosion in alkaline solutions using both computational and experimental techniques.

A now-expired medication called isoprinosine was examined in NaOH (0.50 M) solutions as a potential novel inhibitor of aluminum corrosion. The inhibitory effectiveness of the isoprinosine compounds was examined utilizing different electrochemical tests (open circuit potential OCP, potentiodynamic polarization and electrochemical impedance spectroscopy EIS), surface examination and quantum calculations.

Electrochemical Investigation of C-Steel Corrosion Inhibition, In Silico, and Sulfate-Reducing Bacteria Investigations Using Pyrazole Derivatives.

The inhibitory impact of the two synthesized pyrazole derivatives ( and ) toward metallic and microbial corrosion was investigated. Using open circuit potential, potentiodynamic polarization, and electrochemical impedance spectroscopy, it was possible to determine their ability to prevent the corrosion of C-steel in 1 M HCl, which was significantly enhanced with increasing concentration (ex. 93%).

Impact of some pyrrolidinium ionic liquids on copper dissolution behavior in acidic environment: experimental, morphological and theoretical insights.

The inhibitive and adsorption activity of some pyrrolidinium ionic liquids (ILs) for the dissolution of copper in 1 M HNO solution was tested using chemical methods such as weight loss and electrochemical techniques; potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and electrical frequency modulation (EFM) techniques. The results indicated that the ionic liquids under investigation exhibited promising corrosion inhibitory performance in 1 M HNO and their efficiencies reached up to 85% at 0.05 mM.
