Summary: The design and development of proton-exchange membranes (PEMs) for fuel cells and related electrochemical devices is crucial for achieving high performance and durability. PFSA-based PEMs have become the commercial standard due to their high proton conductivity and chemical stability, but there is increasing interest in aromatic HC-based PEMs with PTFE reinforcement. In recent years, the focus has shifted towards the development of hybrid and composite ultra-thin PEMs with customized properties.

Summary: Membrane technology with GO and GO-ZnO nanoparticles showed enhanced antifouling properties and pure water flux for oily wastewater treatment. The modification also improved the hydrophilicity of the membranes. The presence of ZnO increased the distance between GO nanosheets, leading to reduced agglomeration and enhanced mechanical strength of the membranes. The membranes with nano additives exhibited lower flux reduction and higher turbidity removal efficiency compared to neat PVC membranes.

Summary: Green hydrogen produced by water electrolysis powered by renewable electricity can replace fossil fuels. Anion-exchange-membrane (AEM) electrolyzers offer advantages of commercial proton-exchange-membrane systems with the use of less expensive materials and catalysts. Limited research and development in AEM electrolyzers due to lack of accessible materials and difficulty in comparing results, but using commercially available materials can provide a high-performance baseline for future development.

Summary: The rational design guide for cathode and anode catalyst layers using m-TPN1 ionomer can lead to a more uniform ionomer distribution and larger triple-phase-boundary. Enhanced power density of membrane-electrode-assembly is achieved as the ionomer distribution of the cathode catalyst layer becomes more uniform. The power density at fully humidified condition is strongly correlated with the porosity of anode catalyst layer due to the limitation of hydrogen transport at anode by water flooding.

Summary: The study investigated the solute-solvent and solute-solute interactions in mixtures of ibuprofen with water and 1-propanol. Results showed that solute-solvent interactions decrease with increasing temperature, and also decrease with decreasing weight fraction of 1-propanol, possibly due to preferential solvation of ibuprofen with 1-propanol.

Summary: In this study, seven biocompatible poly(ionic liquid)s based on amino acids (AAPIL) were synthesized and their CO2 absorption capacities were investigated. It was found that AAPILs have higher adsorption capacity than normal ionic liquids, mainly due to the amino groups attached to the cation. The results showed that CO2 absorption capacity increases with increase in pressure and reduce in temperature, and the number of amino groups in the AAPILs is responsible for their absorption capacities.

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.
