Summary: Adsorption separation technology shows promise as an alternative to energy-intensive cryogenic distillation for natural gas separation. However, the performance of adsorbents for CH4/N-2 separation under humid conditions is challenging due to dampening by water vapor. This study demonstrates the improved performance and moisture stability of a series of engineered metal-organic frameworks (MOFs) for CH4/N-2 separation.

Summary: Mesoporous silica nanoparticles (MSN) are potential drug carriers with high drug loading capacity and degradability under biologically relevant conditions. Dissolution studies of MCM-48 MSN in the presence of proteins show that protein concentration affects the kinetics of dissolution and leads to the formation of core-shell structured particles. The results suggest that MSN dissolution kinetics is faster under typical in vitro conditions compared to full serum conditions.

Summary: The rapid fabrication of high-performance composite membranes based on CMPs using simple and low-cost methods is challenging. In this study, three CMPs-based composite membranes were rapidly fabricated with adjustable size using unidirectional diffusion synthesis. The microstructural design enhanced the rejection rates of the membranes and they showed strong hydrolytic resistance, thermal stability, and acid-base resistance. Electrostatic adsorption and the adjustable microstructures significantly varied the repellence of the membranes to different charged molecules.

Summary: Introducing defects into porous metal-organic frameworks is important for improving their adsorption performance. Quasi-MOFs, an underutilized variant of large-scale, fundamentally deficient MOFs, have been found to have substantial amounts of unsaturated metal sites to offset the drawbacks of MOFs. In this study, a quasi-MOF was produced using a water-stable MOF and demonstrated significantly improved phosphate adsorption capability due to the presence of defect sites.

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.
