Summary: Novel thermally rearranged polybenzoxazole (TR-PBO)-based silica hybrid membranes were prepared and investigated for gas transport properties, showing increased gas permeability with higher silica content due to the formation of free volume holes at polymer/silica interfacial region. The membranes exhibited outstanding CO2/CH4 selectivity exceeding the upper bound trade-off line, achieved through the synergistic effects of enlarged FFV and formation of size-selective free volume holes at polymer/silica interfacial region.

Summary: In this study, the in-plane Young's moduli E-parallel to of 2D lead halide Ruddlesden-Popper HOIPs were systematically investigated. It was found that E-parallel to generally follows the trend of Pb-X bond strength, showing more prominent effects of the metal halide inorganic framework on E-parallel to than E-perpendicular to.

Summary: The traditional method of identifying potential membrane materials based on comparing the aperture size of a membrane with the kinetic diameters of gases may fail for CO2 separations using metal-organic frameworks (MOFs). Coulombic interactions significantly influence the diffusion of CO2 in MOFs, causing the transport bottleneck of CO2 and other gases to be at different locations in studied MOF structures.

Summary: Mixed matrix membranes (MMM) incorporating hierarchically structured metal-organic framework (MOF) fillers show improved gas separation performance, with 4-fold enhancements in CO2 and CH4 permeabilities and increased selectivity and plasticization resistance. The method involves the synthesis of hierarchical ZIF-8 particles for compatibility with polyimide (PI) in MMMs. The enhanced gas transport properties are attributed to the modified PI structure and hierarchical nature of H-ZIF-8.

Summary: The article presents the findings of a study on the impact of Poland's energy mix transformation on its energy security. The study used the MANOVA model to examine the relationship between the share of coal in the energy mix and factors such as greenhouse gas emissions, energy availability, and energy prices. The results showed that the energy surplus was related to changes in the share of coal, while no significant relationship was found between prices and emissions and the changes in coal share. A simulation also indicated that reducing emissions by 6% and prices by 17% could establish a correlation between price, emissions, and the share in the mix.

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.
