Summary: In this study, pervaporative mixed matrix membranes (MMMs) composed of newly synthesized porous UiO-66 filler and poly (vinyl alcohol) (PVA) were investigated for dewatering n-butanol (BuOH) from BuOH/H2O and BuOH/ethanol/H2O solutions. The effects of filler loading, feed concentration, and feed temperature on membrane dehydration performance were studied in terms of pervaporation flux/separation factor, pervaporation separation index, and component permeance/selectivity. The results showed that increasing the feed water concentration or temperature led to an increase in total permeation flux but a decrease in dehydration separation factor. The UiO-66/PVA MMMs exhibited great potential for practical BuOH dehydration applications.

Summary: In this study, mixed matrix membranes (MMMs) of poly(vinyl alcohol) (PVA) and porous H-beta zeolite were investigated for ethanol, n-propanol, and isopropanol dehydration via pervaporation. The addition of H-beta zeolite resulted in higher permeation flux and better separation efficiency compared to pure PVA, attributed to the zeolite's pore size and hydrophilicity. Overall, PVA/H-beta zeolite MMMs show promising potential for alcohol dehydration applications.

Summary: Ti3C2Tx MXene nanosheets were synthesized and loaded into UV-curable APVA to fabricate APVA-MXene MMMs for ethanol dehydration by PV process. The incorporation of MXene nanosheets into the APVA matrix resulted in increased permeation flux and separation factor due to laminated structure, excellent compatibility, and high surface hydrophilicity. The optimal separation performance was achieved when the MXene loading reached 3 wt%, with a permeation flux of 942 g/(m(2).h) and a separation factor of 294.

Summary: In this study, the asymmetric separation layer of MOF-filled mixed matrix membranes (MMMs) was etched using long-distance and dynamic low-temperature (LDDLT) plasma to enhance ethanol permselective pervaporation. The etching process reduced the thickness of the separation layer and increased the amount of MOF on the surface, leading to a significant reduction in molecular permeation resistance and improvement in membrane performance. The etched MMMs exhibited superior permeation flux and separation factor compared to the unetched membrane in the separation of 5 wt% ethanol aqueous solution at 40 degrees C.

Summary: The study aimed to investigate the effectiveness of a single loading dose of dexmedetomidine combined with propofol for deep sedation during endoscopic retrograde cholangiopancreatography (ERCP) in elderly patients. The results showed that the cumulative dose of propofol was lower in the dexmedetomidine group compared to the propofol group, and the occurrence of artificial airway interventions and hypotension was also lower in the dexmedetomidine group. Therefore, the combination of a single loading dose of dexmedetomidine with propofol can provide better outcomes for deep sedation in elderly patients during ERCP.

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.
