Summary: The deteriorating environmental quality requires rapid in situ real-time monitoring of toxic compounds in water and wastewater. Nitrite ion, one of the most toxic nitrogen-containing ions, can be quantitatively monitored in wastewater using an MFC-based biosensor at low and moderate concentrations, but higher concentrations lead to a significant drop in MFC voltage, indicating a potential for use as an early warning device for extremely high nitrite pollution.

Summary: Bioelectrochemical systems, particularly microbial fuel cells (MFCs), are becoming popular for their environmentally friendly energy generation and bioremediation. To improve electron transport and biocompatibility, better anode materials are required. Waste palm kernel shell-derived graphene oxide (PKS-GO) and reduced graphene oxide (PKS-rGO) were used as anode electrodes in MFCs, with PKS-rGO generating more energy and higher current densities than PKS-GO. The PKS-rGO anode also showed enhanced capacitance and faster electron transport rate. In addition, PKS-rGO was more effective than PKS-GO in bioremediating formaldehyde in wastewater treatment. This study provides insights into the effectiveness of PKS-rGO as an anode material for MFCs.

Summary: A combination of experimental studies and drift-diffusion modeling is used to investigate the appearance of inverted hysteresis in perovskite solar cells. The influence of different parameters on hysteresis behavior is examined, and a drift-diffusion model is used to simulate the experimental trends. It is shown that the accumulation and depletion of ionic charge at the interfaces modify carrier transport and injection/recombination processes, leading to hysteresis.
