Summary: The traditional method of identifying potential membrane materials based on comparing the aperture size of a membrane with the kinetic diameters of gases may fail for CO2 separations using metal-organic frameworks (MOFs). Coulombic interactions significantly influence the diffusion of CO2 in MOFs, causing the transport bottleneck of CO2 and other gases to be at different locations in studied MOF structures.

Summary: In this study, a method for the confined growth of metal-organic frameworks (MOFs) in melamine-based COF pores (mCOFs) was proposed. The COF-MOF nanohybrid particles (CXMs) were fabricated, and a Pebax membrane with excellent size sieving and high molecular transport was developed. The CXM/Pebax membrane showed significantly improved CO2/CH4 selectivity and enhanced long-term stability. The optimized membrane achieved a CO2/CH4 selectivity of 44.2 +/- 1.3, surpassing Robeson's upper bounds and maintaining 94% of its initial selectivity in long-term tests, which was 25% higher than the unmodified membrane.

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.
