Summary: Water management is a significant challenge in fuel cells, affecting their performance and durability. This study utilized a model reaction system to observe the flooding phenomenon at the gas/electrode interface during the oxygen reduction reaction and hydrogen oxidation reaction. The formation of micrometer-sized droplets was observed during ion-generation reactions, while no obvious droplets were observed during ion-consumption reactions. The flooding phenomenon was attributed to the decrease in saturated vapor pressure caused by ion generation, while the non-flooding phenomenon was due to the elevated vapor pressure caused by ion consumption.

Summary: This work presents a versatile chemistry platform for the fabrication of hierarchical cation and anion exchange membranes (hCEMs and hAEMs) with tuneable transport properties. The hierarchical ion exchange membranes were made by coating and UV crosslinking an acrylic ionomer on top of a PVC-SiO2 porous substrate. The properties and performance of the membranes were found to be dependent on the coating crosslinking density, with higher crosslinking density resulting in better selectivity and performance.

Summary: In this study, CF-ZrO2/ZrC composites with controllable coating thickness were prepared using an in-situ sol-gel method. By changing the hydrophobicity of the carbon fibers surface, the interface affinity was increased, ensuring the preparation of uniform coatings. The coating layer increased the thickness of the composites and prevented further oxidation of internal carbon. This method effectively improved the ablative resistance and thermal decomposition temperature of the composites.

Summary: The use of ion exchange membranes (IEMs) leverages the selectivity of the membranes for electrochemical ion-ion separation, but a mechanistic model for relating selectivity with membrane properties is lacking. In this study, we extend Manning's counter-ion condensation model to mixed salts scenarios and evaluate its performance against experimental data. Our analysis shows that the extended Donnan-Manning model generally outperforms the ideal Donnan model and the Donnan-Affinity model in predicting ion partitioning and mobility selectivity. However, its performance for anion exchange membranes is still unsatisfactory.

Summary: Ceramic membranes with high heat and chemical resistance are essential in the nanofiltration process under harsh conditions. In this study, alumina-titania composite ceramic membranes with a gamma-alumina interlayer were fabricated using sol-gel and dip coating techniques for salt rejection. The membranes exhibited crack-free surfaces after calcination at 450°C. XRD analysis revealed the crystal structure of the membranes. The rejection rate of chlorine was pH-dependent. This research provides a composite ceramic nanofiltration membrane for high-pressure desalination, and the membrane's surface remained unchanged after five cycles, making it a promising candidate in the wastewater treatment field.

Summary: In this study, core-shell ZIF-8@RF nanofillers were incorporated into 6FDA-Durene and Pebax 1657 via a physical blending approach to form MMMs, which showed outstanding performance for CO2/CH4 separation due to enhanced interfacial compatibility, CO2 affinity, and the intrinsic characteristics of porous ZIF-8. The CO2 permeability and CO2/CH4 selectivity of the MMMs increased significantly compared to the pristine membrane, and the presence of RF layer in ZIF-8@RF MMMs further improved the CO2/CH4 selectivity. Importantly, both MMMs maintained their excellent separation performance even in the presence of moisture.

Summary: In this study, a sequential Pd-modified polymeric ultrafiltration (UF) membrane was developed for the rapid and economic removal of NDMA. The membrane achieved complete elimination of NDMA using direct electrochemical reduction and Pd-catalyzed hydrogenation. The pre-rejection of interfering substances and the flow-through operation mode improved the stability and reaction kinetics of the membrane, respectively. The combined treatment of the membrane and nanofiltration showed superior performance compared to conventional reverse osmosis in terms of NDMA removal and energy usage. This work provides a new strategy for developing energy-efficient wastewater treatment systems.

Summary: To achieve precise removal of trace FLO in the presence of various high-concentration interferents in water, a novel oxygen vacancy engineered molecular imprinted TiO2 (MI-TiO2-x) cathode material was developed. MI-TiO2-x exhibited enhanced recognition and accelerated interfacial charge transfer due to its molecular imprinted sites and oxygen vacancy, respectively. It demonstrated superior dehalogenation performance, outperforming most recent electrocatalysts, and showed resistance to co-existing interferents. In an electro-reductive and biological coupling system, MI-TiO2-x effectively removed the antibacterial activity of FLO in swine wastewater and eliminated the abundance of FLO resistance genes. This study provides insights into the rational design of noble-metal-free electrocatalysts for the remediation of low-concentration organic halides and highlights the importance of dehalogenation treatment in mitigating ecological risks.

Summary: A facile and sensitive glucose sandwich assay using surface-enhanced Raman scattering (SERS) was developed. Glucose was captured by 3-aminopheyonyl boronic acid (APBA) modified Ag nanoparticles decorated onto a polyamide surface. APBA forms specific cis-diol compounds with glucose molecules avoiding interference by other saccharides and biomolecules in urine enabling its selective detection. AEPO exhibited a distinctive SERS peak in the Raman silent region, thus increasing the sensitivity of the glucose detection to 10(-11) M. The developed SERS assay was reusable and showed potential as a diagnostic tool for glucose sensing in clinical applications.

Summary: In this study, PVDF-based anion-exchange membranes were designed to selectively separate nitrate from chloride. Experimental data showed that increasing the concentration of PVDF enhanced nitrate transport but also increased the membrane electrical resistance. The selectivity of nitrate was found to be independent of the membrane thickness and mainly driven by the increased affinity between the anion and the membrane.

Summary: This study focuses on the modification of a commercially available polyamide thin-film composite membrane with a zwitterionic material to enhance its fouling resistance. The modified membrane shows improved salt rejection and reduced permeability compared to the pristine membrane. Fouling tests demonstrate that the modified membrane has a lower fouling ratio and higher recovery ratio. The enhanced antifouling characteristics are attributed to the improved hydrophilicity resulting from the zwitterionic brushes and the salting-in effect.
