Summary: Ion transport is crucial for cell proliferation, energy conversion, and homeostasis in living systems. This mechanism has inspired various nanofluidic applications, such as electricity harvesting, molecular sensors, and molecular separation. Through extensive molecular dynamics simulations, we investigated ion conduction across flexible 2D nanoporous membranes and found that the microscopic fluctuations of these membranes significantly increase ion conductance. Our analysis revealed that when the membrane fluctuated within a specific frequency range, the ion hydration was destabilized, leading to improved ion conduction. The dynamic coupling between the fluctuating membrane and ions plays a crucial role in ion conduction across 2D nanoporous membranes.

Summary: ZIF-8 membranes prepared on polyamide substrates demonstrated successful separation of acetylene/methane and acetylene/carbon dioxide mixtures with separation factors of 12.1 and 1.8 respectively. The separation mechanism for C2H2/CH4 is attributed to acetylene affinity and molecular sieving, while C2H2/CO2 separation is related to thermodynamic factors. This study marks the first successful separation of C2H2 from CH4 and CO2 by MOF membranes.

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 use of machine learning to predict the performance of specific adsorbents in phosphate adsorption shows great promise in saving time and revealing underlying mechanisms. However, the small size of the dataset and insufficient detailed information limits the model training process and the accuracy of results. To address this, the study employs a fuzzing strategy that replaces detailed numeric information with descriptive text messages on the physiochemical properties of adsorbents. This strategy allows the recovery of discarded samples with limited information, leading to accurate prediction of adsorption amount, capacity, and kinetics. The study also finds that phosphate uptake by adsorbents is generally through physisorption, with some involvement of chemisorption. The framework established in this study provides a practical approach for quickly predicting phosphate adsorption performance in urgent scenarios, using easily accessible information.
