The power overshoot generated by electron depletion in microbial fuel cells (MFCs) was characterized in this study. Various causes of power overshoot, identified in previous studies, are discussed in terms of their plausible contributions to electron depletion. We found that power overshoot occurred if the anodic overpotential generated by electron depletion exceeded the cathodic overpotential. The introduction of assistance current from anode connections, which ameliorated the electron depletio

The structural efficiency of composite panels with tailored fibre paths has attracted great attention in recent decades. It was proved analytically that tailoring of the in-plane stiffness of composite laminates can improve the buckling and postbuckling characteristics by redistributing the applied loads [1-3]. Experimental research demonstrated its superior stiffness and buckling characteristic as well [4-5]. Currently, there is significant interest in developing methodologies to design optimal

Abstract Herein, an assistance current is suggested as a new approach to prevent voltage reversal in series‐connected microbial fuel cells (MFCs). This approach can be used to revive reversed MFCs, as a supporting assistance current is applied through an assistance anode when voltage reversal occurs. However, when the assistance current is applied without control over the assistance current, voltage reversal is regenerated. Therefore, to control the assistance current, the suggested approach is

Extracellular electron transport (EET) is a biological process where microorganisms can donate electrons from the interior of their cells to external electron acceptors or act as electron acceptors to receive electrons from external sources and electrodes. This process often occurs in the surrounding environment or within biofilms, enabling the redox reactions essential for energy metabolism. This review evaluates the latest developments in electron transfer (EET) research in environmental biote
