Summary: This study investigated the toxicity of low-dose PFBS on liver and compared it with PFOS. The results showed that PFBS exposure induced cell apoptosis and decreased CAT activities, while PFOS exposure led to accumulation of lipid droplets, increase of CAT activities, and TAG levels. Lipidomics analysis revealed similar global lipid changes in the two PFBS-treated groups, distinct from PFOS.

Summary: Trace organic compounds from effluent streams can contaminate groundwater sources as they are not completely removed by conventional purification techniques. In this study, we investigated the removal efficiency and rejection mechanisms of three common pharmaceutically active compounds using different surface characteristics of commercial nanofiltration and reverse osmosis membranes. The results showed that RO membranes exhibited near-complete removal of all compounds, while the retention capabilities of NF membranes varied depending on the characteristics of the compounds, membranes, and feed solution.

Summary: Metal-organic frameworks (MOFs) with different metal nodes and organic ligands were prepared and used to remove perfluorooctane sulfonate (PFOS) from water. Among them, MIL-53(Al) showed the best PFOS adsorption performance due to its highest unsaturated metal active sites and smallest pore size, while longer organic ligands were found to contribute to better PFOS entry and performance. The presence of Fe3+ ions in MOFs/PFOS system improved PFOS removal through bridging and interaction, as confirmed by density functional theory (DFT) calculation. These optimized MOFs are promising adsorbents for sustainable removal of PFOS from water.

Summary: Trace organic compounds (TOrCs) are a critical concern for water quality and safety, with advanced water treatment technologies like reverse osmosis (RO) and nanofiltration (NF) membranes showing promise in removing these compounds. The rejection mechanisms of TOrCs by RO/NF membranes remain unclear due to differences in membrane structures and limited research on TOrCs. This review focuses on characterizing rejection mechanisms and proposes future directions for improving TOrC separation performance of RO/NF membranes.

Summary: This study investigated the separation mechanisms of matrine (MT) and oxymatrine (OMT) in Sophora flavescens using four nanofiltration membranes. The results showed that rejection by NT101 and NF270 was primarily influenced by electrostatic and hydrophobic effects, while NF90 and NT103 maintained high rejection due to the sieving effect. In addition, binary mixtures of MT and OMT could be separated by NT101, possibly due to competition for adsorption on the membrane. Molecular dynamics simulations provided insights into the interactions between the alkaloids and the membrane, explaining the enhanced rejection of OMT in the presence of MT. This study offers valuable guidance for the effective application of membrane technology in the separation of natural products.

Summary: This study modified NF90 and NF270 nanofiltration membranes through interpenetrating polymer networks, and the best modified NF90 membrane showed an increase in water flux by 84.3% and chloride rejection by 0.6% compared to the commercial membrane. Additionally, the best membrane modification achieved a 300% increase in seawater permeability without sacrificing the high rejections of the original membranes. This work provides a guide for improving the permeability of NF membranes without sacrificing higher species rejection through modification with interpenetrating polymers.

Summary: This study investigated the effects of pH, humic acid, fulvic acid, and Na2SO4 on the distribution of PFOS isomers between hydrargillite and the water phase. The results showed that the distribution coefficients of PFOS isomers increased at lower pH and decreased at alkaline conditions. The presence of humic substances slightly increased the sorption, while Na2SO4 contributed to increased sorption through ionic strength effects.

Summary: This study focused on the semihydrogenation of acetylene in an ethylene-rich stream using two alloyed Pt catalysts PtCu and PtCo. The PtCu catalyst showed higher activity and ethylene yield compared to PtCo due to its higher unoccupied Pt d-orbital density. This indicates that alloying Pt with Cu is more promising for industrial relevant SHA catalyst.

Summary: This work presents a continuous solvent extraction method for the separation of cobalt and nickel in a millifluidic system using Cyphos IL 101 (C101) as the extractant. The optimal conditions for extraction performance and solvent properties were determined by investigating the effects of channel length, flow rate, and temperature. The performance of a developed manifold structure was compared to a single-channel system, and excellent separation results were achieved. The continuous separation process using the manifold structure resulted in high purity cobalt and nickel products.

Summary: The use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
