“…It is evident from this figure that the impedance diagrams consist of a large capacitive loop at high frequency followed by an inductive loop at low frequency. The first loop is due to the formation of an oxide film on the aluminum surface, while the second one is attributed to the relaxation of the charged intermediates adsorbed on the surface tested [50,51]. In addition, the inductive semicircle diameter is considerably less than that observed in high frequencies.…”

According to the literature, the works on the inhibition of aluminum alloy corrosion using naturally occurring compounds are limited. For this, the inhibiting effect of oil mill liquid by-product (OMW) on the corrosion of 3003 aluminum alloy (AA3003) in molar hydrochloric acid solution was evaluated using electrochemical techniques. In parallel, a computational approach based on DFT/B3LYP and Monte Carlo methods was used to understand the inhibition process under electronic and atomic scales, respectively. The experimental results reveal that OMW has a good inhibiting effect on the corrosion of AA3003 alloy in the tested solution and acts as a cathodic inhibitor. The inhibitory efficiency increases by increasing OMW concentration to attain 89% at 6.0 ppm. The effect of temperature shows that the inhibition efficiency of OMW decreases with temperature rising. Nevertheless, a good prevention capacity of 83% is obtained at 338 K. Such interesting achieved protection property was attributed to the adsorption of OMW constituents onto the alloy surface via a mixed physichemisorption process. This process is found to obey the Langmuir adsorption isotherm. Furthermore, the activation thermodynamic parameters of the corrosion process of AA3003 alloy were also determined and discussed. The computational outcomes outlined the ability of the OMW components to interact favorably with the metal surface, hence the formation of a protective layer, which justified the observed inhibition behaviors. Conferring to the present study, OMW can be used as a good green corrosion inhibitor for AA3003 alloy in the acidic medium.

“…Table S1 also reveals that the deviation between the experimental and calculated values is less than 10%. These results suggest that the electrochemical impedance spectrum with the Randles-type equivalent circuit can be used for glucose detection [47]. As depicted in (D), the presence of the target produces a 9 ohm decrease of R ct in MIP@Ni foam, while no significant change of the R ct value is observed in NIP@Ni foam.…”

Here we report a new molecularly imprinted electrochemical sensor (MIECS) for the impedimetric enzyme‐free analysis of glucose. A computational modeling strategy was first utilized to screen promising functional monomers for imprinting assembly, and simulation data suggested that methacrylic acid (MAA) exhibited a preferable capability to recognize the target molecule compared to other common monomers. Then the MIECS was prepared via introducing MAA‐based recognition sites onto a porous Ni foam with large surface. The fabricated sensor was subtly characterized by Raman spectroscopy, scanning electron microscopy, and cyclic voltammetry, and an impedimetric method was selected to detect the glucose target in a basic medium. Experimental results demonstrated that the proposed MIECS could selectively recognize glucose against coexisting species, with good linear responses of the charge transfer resistance upon the target concentration in the scope of 10∼55 mM. These results indicate its potential applications in the recognization and detection of glucose in complex matrices.

Highlights DM drug was introduced as a novel corrosion inhibitor. Polarization measurements signify that DM drug acted as a mixed mode inhibitor. Adsorption mode best reflect in Langmuir isotherm. MD-simulation reveals the vital role of active sites of DM molecule in their adsorption. ANFIS best predicted the interactive effects between the input and output response.
