Summary: In this study, protein fouling within a polymeric microfiltration membrane was characterized in real time using nonFaradaic electrochemical impedance spectroscopy. By modeling the electrochemical system with equivalent circuit components, both qualitative and quantitative monitoring of protein fouling was achieved, marking the first attempt to deploy a conductive polymeric membrane as an active electrode in an EIS setup.

Summary: This study simulated the electrochemical impedance of a mixed ion-electron conducting SOFC cathode based on experimentally determined 3D microstructure, revealing a need to modify existing models to account for differences in oxygen vacancy concentrations. The results showed that the effective tortuosity is dependent on frequency and material properties, challenging the prevalent practice of treating tortuosity as a constant value. A method for determining the dependence of tortuosity on material properties and frequency using EIS data was proposed.

Summary: Electrochemical impedance spectroscopy (EIS) is a valuable tool in membrane science and technology that provides information on the structure and functionality of the membrane. By studying multipore asymmetric membranes with conical pores, it was found that the ionic conduction properties can be modulated by adjusting the electrical interaction between charges on the pore surface and the nanoconfined ionic solution. The membrane's electrical response was found to be influenced by the amplitude and frequency of the external voltage signal, the electrolyte type and concentration, and the solution pH.

Summary: To cope with the premature deterioration of reinforced concrete structures caused by chloride-induced corrosion, estimating the corrosion rate and calculating transport parameters is necessary. However, interpreting the impedance response of steel embedded in concrete is still challenging. Concrete acts as a good barrier but can contain unexpected or invisible variables that hinder electrical measurements. Overcoming these limitations requires confirming impedance responses under controlled variable cases.

Summary: In this study, nanocomposites were prepared by spin coating, with NiO nanofillers incorporated into PMMA using the Pechini method. The interactions between the matrix and reinforcement were analyzed using FTIR spectroscopy. SEM images revealed the non-uniformity of circular void structures in homogenized PMMA. Electrochemical tests demonstrated redox reactions attributed to the addition of NiO in PMMA, with specific capacitance ranging from 119 to 407 mu F.g(-1) for PMMA/NiO 1% and 5%, respectively. EIS analysis showed typical behavior of capacitive materials. Complex capacitance values reached 35, 40, and 43 mu F.cm(-2) for PMMA/NiO. The results indicate the potential application of PMMA/NiO in electronic devices.
