“…According to the literature review, graphene oxide is considered as the most effective and dynamic material for the electrode. The graphene oxide is gaining much attention for electrodes preparation due to high surface area, excellent mechanical stability, thermal stability and good conductivity [33]. The conducting polymer and other material composites also exhibit a remarkable result.…”

A wide variety of pollutants are discharged into water bodies like lakes, rivers, canal, etc. due to the growing world population, industrial development, depletion of water resources, improper disposal of agricultural and native wastes. Water pollution is becoming a severe problem for the whole world from small villages to big cities. The toxic metals and organic dyes pollutants are considered as significant contaminants that cause severe hazards to human beings and aquatic life. The microbial fuel cell (MFC) is the most promising, eco-friendly, and emerging technique. In this technique, microorganisms play an important role in bioremediation of water pollutants simultaneously generating an electric current. In this review, a new approach based on microbial fuel cells for bioremediation of organic dyes and toxic metals has been summarized. This technique offers an alternative with great potential in the field of wastewater treatment. Finally, their applications are discussed to explore the research gaps for future research direction. From a literature survey of more than 170 recent papers, it is evident that MFCs have demonstrated outstanding removal capabilities for various pollutants.

“…S20). The undistorted triangular shaped galvanostatic charge/discharge (GCD) profile proved the highly capacitive characteristics of PA/CNT (0/100) fiber [30]. It is noteworthy that the capacitive characteristic of PA/ CNT (0/100) fiber was well-maintained even up to a scan rate of 10,000 mV s −1 , which highlighted the good electrical conductivity itself.…”

Monofilament type of polyaromatic amide (PA) and carbon nanotube (CNT) composite fibers is presented. A concept of a lyotropic liquid crystal (LLC) constructed via a spontaneous self-assembly is introduced to mitigate the extremely low compatibility between PA and CNT. These approaches provide an effective co-processing route of PA and CNT simultaneously to fabricate the uniform, continuous, and reliable composite fibers through a wet-spinning. Interestingly, the addition of a small amount PA into the dope solution of CNT governs the LLC mesophase not only in a spinneret stage but also in a coagulant region. Thus, the developed PA/CNT composite fibers have the high uniaxial orientational order and the close interfacial packing compared to the pure CNT fibers. The PA/CNT composite fibers achieve the outstanding tensile strength, electrical conductivity, and electrochemical response, while maintaining a lightweight. They also exhibit the chemical, mechanical, and thermal robustness. All of these advantages can make flexible, sewable, and washable PA/CNT composite fibers ideal nanocomposite materials for use in next-generation information and energy transporting system by replacing conventional metal electrical conductors. Graphical Abstract The lyotropic liquid crystal self-assembly governed by doping the aramid polymers shows the ability to construct mechanically strong and continuous carbon nanotube-based composite fibers that can be used in the lightweight and robust electrical wiring for extreme environmental applications.

“…Herein, the equivalent resistance was not only the charge-transfer resistance but was also combined with the electrolyte resistance, electrode material resistance, and the resistance of the interface electrode-electrolyte. [39][40][41] The different equivalent series resistance values of three different working electrodes in one type of aqueous table salt electrolyte, suggest that there is a different contact resistance of the electrode-electrolyte, and a different electrode material resistance. 42,43 All the linear lines in the low frequency EIS plots indicate the capacitive effect of ion diffusion, 44 whereas the Warburg impedance arose at a high frequency as a result of the ion diffusion resistance in the electrode layer.…”
