Summary: Biomass-derived N/S dual-doped porous carbon adsorbent MZ-NSPC exhibits excellent adsorption capacity, short equilibrium time, and good reusability due to its large BET surface area, hierarchically porous structure, and N/S heteroatoms dual-doping. Doped N, S heteroatoms synergistically promote the adsorption performance, mainly targeting oxidized-S and pyridinic-N sites. The adsorption mechanisms for bisphenol F involve hydrophobic interaction, pi-pi interaction, and hydrogen bonding interaction, while those for bisphenol S are mainly controlled by pi-pi interaction. This study not only advances the development of low-cost and sustainable heteroatom-doped carbon materials but also systematically investigates the adsorption mechanisms for bisphenols.

Summary: The application of aqueous zinc ion batteries has been limited by the problems of zinc anodes, but a new strategy using sodium hyaluronate has been proposed to reconstruct the electric double layer and improve the performance of the batteries. Experimental and theoretical results show that this strategy can achieve stable and reversible zinc deposition/stripping with low-temperature performance, providing a new perspective for the design of zinc anodes and safe aqueous cells.

Summary: This study assessed the potential of three aquatic macrophytes (Iris pseudacorus, Ipomoea aquatica, and Typha angustifolia) to remove BPS from secondary wastewater effluent. The results showed that these plants could remove BPS at a concentration of 0.005 mg/L with removal rates of 100%, 97%, and 97.5% for I. pseudacorus, I. aquatica, and T. angustifolia, respectively. Twelve biotransformed products of BPS were identified, and a lab-scale vertical phytoreactor was constructed to completely remove BPS along with nutrients and inorganic contaminants from the wastewater.

Summary: This study explored the removal of BPS with multi-enzymes extracted from waste sludge and reed sediment, finding that BPS could be efficiently removed through enzymolysis and bio-flocculation. The polymerization of BPS through enzymolysis enhanced the bio-flocculation removal, while the loose skeletal structure of the multi-enzymes and the hydrophobic microenvironment of amino acid residues were found to be responsible for the removal of BPS.

Summary: The study found that Navicula sp. is more sensitive to BPS toxicity compared to Chlorella vulgaris, which has a higher tolerance. Additionally, the activities of superoxide dismutase (SOD) and catalase (CAT) in Chlorella vulgaris increased at 20 mg BPS/L, while they increased in Navicula sp. at 1 mg BPS/L. Both algae had removal effects on BPS at 0.5 mg/L, but the removal efficiency decreased as BPS concentration increased. Navicula sp. showed better removal due to higher accumulation, suggesting they may be good materials for BPS removal.

Summary: This study demonstrates the integrated modification of Na2Ti6O13 (NTO) using Nb-doping, leading to significantly improved cycling and low-temperature performance. Theoretical investigation suggests that Nb substitution enhances structural stability and reduces diffusion energy barrier. In situ experiments further confirm the robust spring effect of the Ti-O bond in NTO, which plays a key role in overcoming transport kinetics issues and low conductivity.

Summary: Based on electromagnetic induction heating method, this study investigates the heating and curing of Carbon Fiber Reinforced Polymer (CFRP), which has the advantages of high energy utilization and no pollution. An electromagnetic heating finite element analysis model for CFRP circular tubes was established to analyze the temperature field influenced by the material weaving structure and mold material. Experimental results show that the temperature field changes with the CFRP structure when the glass fiber-reinforced plastic mold is heated, and the more fiber cross points, the more uniform the temperature field. The accuracy of the finite element model was verified through experiments. The aim of this research is to provide theoretical guidance for actual industrial production.

Summary: The implementation of 4th or 5th generation district heating systems requires a complex solution involving energy sources, heating networks, and consumers. System dynamics modeling is used to evaluate long-term effectiveness and analyze the impacts of different policy measures. Subsidies have a greater impact on key targets than tax increases, and a combination of policies can increase the share of renewable energy sources in district heating.

Summary: LiNixCoyMn1-x-yO2 (NCM) is a critical cathode material for lithium-ion batteries in electric vehicles. The aging of cathode/electrolyte interfaces leads to capacity degradation and long-term cycle instability. A novel neural network model called ACGNet is developed to predict electrochemical stability windows of crystals, allowing for high-throughput screening of coating materials. LiPO3 is identified as a promising coating material with high oxidation voltage and low cost, which significantly improves the cycle stability of NCM batteries. This study demonstrates the accuracy and potential of machine learning in battery materials.

Summary: In this study, a bifunctional electrode host design consisting of carbon nanofibers implanted ordered porous Co-decorated Al2O3 supported on carbon nanotube film (CNTF) was proposed to address the shuttling effect of lithium polysulfides (LiPSs) and dendrite formation of metal lithium anode in lithium-sulfur (Li-S) batteries. The electrode exhibited excellent conductivity, efficient confinement of LiPSs, and catalytic conversion performance, resulting in high initial capacity and good capacity retention during cycling. As an anode, the electrode showed excellent Li+ diffusion performance and uniform lithium growth behavior, achieving a dendrite-free lithium electrode. The flexible pack cell assembled from these electrodes delivered a specific capacity of 972 mAh g(-1) with good capacity retention.
