Aqueous Extracts of Opuntia Ficus-Indica as Green Corrosion Inhibitor of A283C Carbon Steel in 1N Sulfuric Acid Solution

The effect of concentration and temperature were studied to measure the inhibiting capacity of extract Opuntia ficus-indica by using polarization and electrochemical impedance spectroscopy. The adsorption of the studied extract on carbon steel surface obeys the Langmuir adsorption isotherm.

The effect of additional off-diagonal disorder of interionic interaction on charge-storage in sub-nanometer pores of supramolecular carbon supercapacitors

In this work, we report sub-nanoporous carbon which is synthesized for the first time by means of supramolecular engineering methods for efficient energy storage at the electrode/electrolyte interface. The achieved value of the differential capacitance more than twice exceeds the corresponding value for the known carbon structures. Based on the constructed impedance model and microscopic theory, the physical mechanisms of the investigated processes are suggested.

Mathematical modeling of subdiffusion impedance in multilayer nanostructures

The model of impedance subdiffusion based on the Cattaneo equation in fractional derivatives in applications to multilayer nanostructures is considered. Nyquist diagrams with changes of the parameter $\tau$ (time for which the flow is delayed with respect to the concentration gradient) and the subdiffusion coefficient $D_{\alpha }$ are calculated.
