Summary: The study focused on the synthesis and performance evaluation of Co-Ni nanoparticles supported on Al2O3-GO matrix for oxygen reduction reaction in single-chambered microbial fuel cells. The hybrid catalyst Co-Ni (2:1)/Al2O3-GO showed higher stability and electrocatalytic activities compared to Pt/C catalyst, resulting in improved ORR rate and power density in MFCs. The enhanced electrocatalytic activity was attributed to the high electronic conductivity and long stability of the nanocomposite, making it a promising alternative to traditional Pt/C catalysts for MFC applications.

Summary: This study presents a method for selectively recovering cobalt from mixed lithium-ion battery electrode materials using a green deep eutectic solvent (DES). The optimized solvent extraction procedure efficiently recovers cobalt as cobalt oxalate, which is then used to produce high-performance lithium cobalt oxide cathode material. The demonstrated selectivity of the leaching method and the ability to reuse the residual DES solution offer a green recycling alternative for reintroducing strategic materials into the lithium-ion battery production chain.

Summary: By incorporating molybdenum sulfide (MoS2) nanosheets and applying external electrical assistance, both the 2D channel and charge density of reduced graphene oxide (rGO) membranes were regulated to enhance water flux and salt rejection. The resulting rGO/MoS2 membranes exhibited expanded nanochannels, resulting in significantly increased water permeance. In addition, the high capacitance and negative potential of the membranes contributed to improved rejection rates for NaCl and Na2SO4 ions. This study provides new insights for the design of membranes with high water flux and salt rejection efficiency.

Summary: Membrane separation is widely used in water and wastewater treatment due to its cost-effectiveness, ease of operation, and high efficiency. However, current membranes face challenges in balancing selectivity and permeability, as well as dealing with membrane fouling. Recent studies have focused on developing high-performance membranes based on carbon nanomaterials, such as carbon nanotubes and graphene, to improve water and wastewater treatment. These carbon nanomaterial-based membranes demonstrate enhanced permselectivity and fouling resistance under electrochemical assistance, thanks to their good electrical conductivity. This review summarizes the progress in the preparation, mechanisms, and applications of electroconductive nanocarbonaceous membranes for water purification and wastewater treatment, aiming to enhance the fundamental understanding of combining membrane separation and electrochemistry. The review covers methods for preparing electroconductive membranes, such as carbon nanotube membranes and graphene membranes, as well as the underlying mechanisms for the improved permselectivity, antifouling, and regeneration performance achieved through electrochemical processes. The review also discusses practical limitations of membrane/electrochemistry systems and proposes possible solutions.

Summary: In this study, heteroatom-doped carbon nanosheets were successfully synthesized using crosslinked triazine frameworks and g-C3N4 nanosheets as a template. The nanosheets exhibited high crinkling and interconnectivity, along with a large surface area (1060 m(2) g(-1)) and pore volume (2.14 cm(3) g(-1)), with highly dispersed N, O and S. When coated on commercial Celgard separators, the modified batteries showed low self-discharge and improved rate performance, even at 4 C. Excellent cycling performances were achieved at different rates, with an initial discharge capacity of 1240 mA h g(-1) and a capacity decay of only 0.059% per cycle for over 1000 cycles at 0.5 C.

Summary: Developing efficient and interference-tolerant catalysts for practical use in catalytic ozonation process is challenging. In this study, a surface Vo-rich catalyst was prepared by doping Co into zinc ferrite spinel, showing efficient mineralization of recalcitrant organic pollutants. The removal of contaminants was mainly attributed to nonradical-based oxygen species, *O, rather than traditional hydroxyl radicals, •OH. The Vo-driven nonradical catalysis exhibited high resistance to coexisting ions and excellent performance in actual wastewater treatment, providing a novel strategy for efficient mineralization of pollutants in complicated water matrices.

Summary: In this study, it was found that electrochemical treatment can expand the restacked regions of reduced graphene oxide (rGO) membranes, leading to the formation of ultrafast water transport nanochannels. The expansion is driven by hydrogen bond interactions between water molecules and electrochemically produced hydroxyl groups on the edges of rGO nanosheets. The treated rGO membranes exhibit a permeance 2 orders of magnitude higher than pristine rGO membranes and about 3 times higher than graphene oxide membranes. Additionally, the rGO membranes also show higher ionic/molecular rejection performance due to their smaller average pore size.

Summary: As a major driver of global methane production, methanogens are exposed to an environment filled with dynamic electromagnetic waves, which may induce electromotive force (EMF) to potentially influence methanogen metabolism. This study found that exposure to a dynamic magnetic field increased biogas production through induced EMF. The methane emissions from sediments increased by 41.71% when exposed to a dynamic magnetic field with an intensity of 0.20 to 0.40 mT. The EMF accelerated the respiration of methanogens and bacteria, leading to enhanced microbial metabolism.

Summary: This study investigated the impact of the non-antibiotic pharmaceutical carbamazepine on antibiotic resistance genes (ARGs) during anaerobic digestion. The results showed that carbamazepine induced the enrichment of ARGs and increased the abundance of bacteria carrying these genes. It also facilitated microbial aggregation and intercellular communication, leading to an increased frequency of ARGs transmission. Moreover, carbamazepine promoted the acquisition of ARGs by pathogens and elevated their overall abundance.

Summary: This paper developed a machine learning model to predict the biochemical methane potential during anaerobic digestion. Model analysis identified lignin content, organic loading, and nitrogen content as key attributes for methane production prediction. For feedstocks with high cellulose content, early methane production is lower but can be improved by prolonging digestion time. Moreover, lignin content exceeding a certain value significantly inhibits methane production.
