Summary: Graphene oxide (GO) lamellar membranes suffer from low flux and poor stability for practical applications due to tortuous transport pathways and weak interlamellar interactions. In this study, porous vermiculite (PVMT) nanosheets were incorporated into the GO-based membranes to establish fast and robust water-selective pathways. PVMT nanosheets provided in-plane pores, reducing the tortuosity and mass transport distance. The hydrophilicity and interlayer distance were enhanced by PVMT nanosheets, contributing to water-selective transport. The resulting membranes exhibited excellent dehydration performance with increased permeation flux and separation factor compared to pristine GO/PTFE membranes, while maintaining stability for 192 h operation. This study may inspire further research in constructing mass-transfer pathways within lamellar membranes.

Summary: This study investigates the relationship between the microstructure and performance of mixed matrix membranes (MMMs) filled with graphene (GR) and graphene oxide (GO). The presence of oxygen-containing groups on GO enhances the membrane's hydrophilicity and permeation properties, while the presence of GR reduces the hydrophilicity and permeation properties. The study highlights the importance of the microstructure and physical properties of graphene in achieving high-performance MMMs.

Summary: The effects of plasma treatment time on the gas permeation and pervaporation dehydration properties of organosilica membranes were investigated. The study found that increasing plasma modification time resulted in a decrease in pore size, leading to an increased He/N2 permeance ratio. The H2O/EtOH permeance ratio also increased from about 20 to over 1000 as the plasma modification time increased due to changes in pore structure and water adsorption properties.

Summary: The sintering process is crucial for nickel hollow fiber membranes (NHFMs), and optimizing the sintering conditions significantly affects the hydrogen permeability and qualified rate of the membranes. This study extensively investigates the effects of sintering conditions on microstructure and hydrogen permeation of NHFMs. Results show that smaller metal grain size leads to enhanced hydrogen permeability, and sintering temperatures significantly affect the grain size and activation energy. Increasing sintering time and hydrogen concentration have minor effects on grain size and hydrogen permeation.

Summary: We demonstrate a composite photocatalyst for nitric oxide conversion with a Cu-Fe alloy, graphitic carbon nitride (g-C3N4), and ZnIn2S4. The superior photocatalytic performance of 6.45-fold that of g-C3N4 was confirmed. The delay effect on charge recombination was observed through time-resolved photoluminescence, and heterojunction establishment was attributed to the hole-trapping ability of ZnIn2S4. The combined effects of the Cu-Fe alloy were confirmed by NO-specific adsorption and conversion experiments, and the active species involved were examined via electron spin resonance. Density functional theory calculations revealed the molecular mechanisms of photocatalytic conversion of NO to NO3-. Therefore, g-C3N4|ZnIn2S4|CuFe has potential for sustainable and efficient pollutant conversion.

Summary: In this study, a La0.8Ca0.2Fe0.94O3-6-0.05Ag (LCF-Ag) hollow fiber membrane with three-layer sandwich structure was successfully prepared. The oxygen permeation flux of the membrane structure was 1.79 times higher than that of the traditional membrane structure, with a maximum oxygen flux of 2.15 mL min-1 cm-2. The membrane showed high stability during a 240-hour long-term operation, and the oxygen flux could be fully recovered by switching the sweep gas to He, indicating its good chemical stability. These results demonstrate the feasibility of the new membrane structure for oxygen separation with CO2 resistance.

Summary: Previous studies have shown that vibration- or rotation-based techniques can effectively mitigate fouling during membrane filtration. However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.
