Summary: The study introduces a new approach for enhancing the lifetime and power output of ceramic microbial fuel cells by utilizing recycled polypropylene nonwoven fabric, demonstrating the strong antifouling effects of ceramic modification. This method successfully increases the long-term efficiency of ceramic MFCs through recycling polypropylene, which is one of the least recycled plastics globally.

Summary: In this study, composite membranes with enhanced output power density were prepared by integrating one-dimensional bacterial nanofibers and twodimensional nanosheets. By complementing the diffusion of oppositely charged ions, superposed electrochemical potential difference and ionic flux were created, resulting in high-performance osmotic power generators.

Summary: The study assessed the feasibility of combining bacteriophages and UV-C irradiation for removing biofoulants in AnMBR, finding a higher log cells removal and EPS concentration reduction. The combination effectively reduced the relative abundance of specific bacteria and created cavities in the biofilm to maintain water flux through the membrane, showing a potential chemical-free method for biofoulant removal.

Summary: Nanofluidic channels constructed using two-dimensional materials show promise for harvesting blue energy. However, current systems have high ion selectivity but suffer from poor mechanical strength and low power density. This study presents a high performance nanofluidic osmotic generator (NOG) using a cellulose nanocrystal/graphene oxide composite membrane, which enhances structural stability and provides efficient space charge for ions transport, resulting in excellent power generation performance.

Summary: N-Oxide zwitterionic polyethyleneimine (ZPEI) was synthesized from commercially branched polyethyleneimine (PEI) for the fabrication of thin-film composite (TFC) polyamide membranes via interfacial polymerization. The ZPEI-TFC membranes showed lower roughness, better surface hydrophilicity, smaller pore size, higher rejection towards salts, and good anti-fouling properties.

Summary: Graft copolymerization is a popular technique for adding different functional groups to polymers. In this study, polypropylene films were grafted with acrylonitrile and acrylic acid monomers to improve their hydrophilicity while maintaining their mechanical qualities. Gamma radiation was used to create active spots on the polymer, allowing the monomer radicals to form grafts. The graft parameters were investigated to maximize graft percentage, and various analytical techniques, such as FTIR, SEM, and XRD, were used to analyze and validate the grafting process. The effects of grafting on the tensile strength and hardness of the films were measured, and a critical grafting degree was determined to preserve these properties. Water uptake, thermal behavior, and cadmium elimination were also studied to further understand the copolymer's characteristics.
