Summary: The use of mixed matrix membranes (MMMs) comprising metal-organic frameworks (MOFs) has been recognized as an effective strategy for enhancing gas separation efficiency. However, the poor compatibility between the filler and matrix may compromise the separation performance. This study modifies the filler to improve its compatibility with the matrix and enhance the selectivity of CO2 over N-2 and CH4.

Summary: Surface tuned GO sheets can effectively enhance the thermo-mechanical properties of epoxy/glass fiber composites. Incorporating N-(2-Aminoethyl)-3-aminopropyltrimethoxysilane functionalized GO (GO-AEAPTS) results in significant improvements in properties such as interlaminar shear strength, impact strength, and thermal conductivity. The enhanced properties are attributed to the uniform distribution of GO sheets, strong interfacial interactions, and good fiber/matrix compatibility.

Summary: In this research, the generalized Korteweg-de Varies-Zakharov-Kuznetsov equation (gKdV-ZK) in (3+1)-dimension was investigated to study the influence of a magnetic field on weak ion-acoustic waves in plasma physics. By utilizing modified extended tanh and extended rational sinh-cosh methods, a wide range of wave structures were analyzed and hyperbolic, periodic, and traveling wave solutions were obtained along with solitary wave solutions. The solutions presented here were found to be distinctive compared to well-known outcomes. Additionally, the results were visualized in 3-dimensional, 2-dimensional, and contour profile graphs to illustrate the dynamics based on parameter selection. The suggested computational techniques were concluded to be simple, dynamic, and well-organized, making them useful for numerical calculations of complex nonlinear problems.

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.
