Summary: This study investigates the potential utility of 2D MXenes as nanofillers to enhance the gas separation performance of polydimethylsiloxane (PDMS) membrane. Mixed-matrix membranes were fabricated by incorporating multilayer MXene (ML-MXene) and single-layer MXene (D-MXene) into PDMS matrices, and the addition of MXene improved the separation capacity of the rubbery dense layers. The optimized D-MXene-loaded mixed-matrix membrane at 1 wt% loading demonstrated a 64.1% increase in CO2 permeability and a 21.3% increase in CO2/N2 selectivity compared to pure PDMS membrane.

Summary: This study fabricated novel dense membranes by blending Pebax with PAMAM and evaluated their application in CO2/CH4 gas separation. The results showed that PAMAM loading, operating pressure, and temperature significantly affected gas permeability and CO2/CH4 selectivity. Gas permeability in the membranes was primarily governed by gas solubility rather than diffusivity. Modifying Pebax membrane with PAMAM improved separation performance with minimal aging and good stability.

Summary: A novel CO2-responsive copolymer was successfully synthesized and used in the fabrication of a blend membrane with switchable water flux. The protonation reaction of PDEAEMA segments within the membrane pores after CO2 aeration led to pore shrinkage and reduced water flux. By taking advantage of the CO2-stimulus responsiveness, a green cleaning method using alternate aeration was adopted to clean protein on the membrane surface, achieving a satisfactory flux recovery rate comparable to traditional cleaning methods.

Summary: Polymeric membranes, particularly those made from a blend of glassy and rubbery polymers like PES and PEG, offer a promising solution to enhance gas separation performance by minimizing the trade-off between selectivity and permeability. The use of solvents like NMP and DMF in membrane fabrication processes can further improve the morphology and separation properties of such polymer blends, making them a major prospect for CO2/N-2 gas separation.

Summary: Novel highly gas-permeable diphenylacetylene polymers were synthesized by introducing methyl groups, which significantly enhanced gas permeability. Removal of the trimethylsilyl group further increased the gas permeability. The gas permeability of the polymers and copolymers was influenced by the methyl groups, and different methyl substituents had different effects on the permeability.

Summary: This study focuses on the recovery of sinapic acid using liquid-liquid extraction assisted by a hollow fiber membrane contactor from an aqueous feed obtained through the hydrolysis of mustard bran. The screening of solvents of different chemical nature showed that all tested solvents had an extraction efficiency of more than 80% for pH < 5. Four solvents were selected for use in the hollow fiber membrane contactor, and the volatile solvents showed higher mass transfer coefficients compared to non-volatile solvents. The extraction efficiency was intensified by increasing the initial concentration of sinapic acid and the feed-to-solvent ratio. CPME was found to have optimal recovery efficiency at a phase ratio of 8:1, yielding 0.9 g of sinapic acid per liter of CPME used.

Summary: In this study, a nanofibrous layered structure of Ff-Ti3C2Tx-Co3O4 was prepared by self-assembling nanofibrous Co3O4 with lamellar fluorine-free MXene (Ff-Ti3C2Tx). The Ff-Ti3C2Tx-Co3O4 exhibited excellent catalytic activity for degradation, resistant to ionic interference, and maintained high removal efficiency of sulfamethoxazole (SMX) in municipal wastewater. The rapid SMX degradation involved fast electron transfer in redox cycles with PMS and the generation of 1O2 via PMS ->center dot O2 -> 1O2. This work provides new insights into antibiotic degradation mechanisms and electron transfer based on PMS activation.

Summary: In this study, sludge-derived biochar (SBC) was functionalized with various iron salts to enhance its adsorption ability for sulfamethoxazole (SMX) and magnetic collection performance. Ball milling was further employed to treat the optimal iron salt functionalized SBC (MSBC), resulting in ball milled SBC (BMSBC) with improved adsorption performance for SMX. The dominant driving mechanism for SMX adsorption onto BMSBC was confirmed to be multiple physicochemical forces, including 7C-7C conjugation, pore filling, H-bonding, Fe-O complexation, and electrostatic interactions. BMSBC exhibited favorable adsorption ability for SMX in actual waters and could be easily collected within 1 min due to its magnetic sensitivity.
