Summary: In this study, a long alkyl chain-containing organosilica layer was utilized to modify silicalite-1 membranes, resulting in bi-layered BTESO/silicalite-1 composite membranes. After BTESO modification, the surface of the membranes became smoother, denser, and more hydrophobic. The modified membranes exhibited good separation performance in pervaporation, with increased ethanol flux and reduced water flux without sacrificing ethanol flux.

Summary: A novel nanoporous hexagonal tungsten oxide membrane was developed for separating water/acetic acid mixtures, with the nanopores on the c-plane allowing for effective separation of the molecules. The synthesis of c-plane-aligned dense NP-h-WO3 membranes via the hydrothermal method on porous ceramic supports was successfully achieved, demonstrating high potential for H2O/AcOH separation. The fabrication of these membranes with a high degree of c-plane alignment was found to be influenced by factors such as the presence of AcOH and the concentration of Na2WO4 in the precursor solution.

Summary: Membrane-based technology is attracting attention due to its low energy consumption, mild operating conditions, and high efficiency. Polymeric membranes are widely used for their low cost and reproducible preparation, but face issues like fouling and trade-off between permeability and selectivity. Inorganic membranes like zeolite membranes, with their hydrophilic nature, high stability, permeability, and selectivity, offer solutions to these problems. Their molecular-level pore size and adsorption property make them suitable for a variety of separation processes, although challenges like reproducibility, defects, and high manufacturing costs still hinder their industrial-scale application.

Summary: Membrane technology is considered a promising alternative for natural gas upgrading, and zeolite membranes, known for their stability, have gained attention. This study investigated the permeation of CO2 through DD3R zeolite membranes in the presence of light gas components. The diffusion of CO2 was slightly affected by N2, CH4, and SF6, but significantly decreased in equimolar CO2/C2H6 due to competitive adsorption and slow diffusion of C2H6 molecules. An empirical formula for predicting CO2 diffusion in ternary mixtures was proposed, providing a convenient method for membrane area determination in multicomponent mixture separation.

Summary: Molecular sieving membranes with ultra-selectivity for CO2/CH4 separation were successfully prepared using a template modulated crystal transition approach. Through one-minute overheating, organic template molecules were converted into tight carbon species and easily burned out by subsequent thermal treatment. The resulting membranes exhibited high CO2/CH4 selectivity and CO2 permeance. This strategy could pave the way for practical applications of all-silica zeolite membranes.

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.

Summary: Increasing temperatures worldwide pose a significant health risk, exacerbated by high humidity. Conventional air conditioners contribute heavily to carbon dioxide emissions, with dehumidification being a major factor. Membrane-based dehumidification system offers energy efficiency and non-toxic water vapor removal. This study demonstrates a membrane dehumidification system with polymeric hollow fibers coated with a green polyphenol coating, showing remarkable water vapor transport rate and selectivity. Long-term testing reveals minimal decline in vapor transport and a 4-5 times higher coefficient of performance (COP) compared to conventional dehumidifiers, making it a highly competitive, energy-saving device with reduced emissions and a smaller footprint.
