Summary: The traditional layer-by-layer (LBL) self-assembly method used for preparing nanofiltration (NF) membranes often has low permeability due to the restricted free volume of the selective layer. In this study, a green and straightforward aqueous immersion method was used to form a coating of plant polyphenol tannic acid (TA) on the substrate surface, addressing the low permeability and rigorous chemical treatment issues. By utilizing this method, an NF membrane with ultrahigh pure water permeance and excellent rejection performance was achieved.

Summary: The interactions between metal cations and graphene derivatives can significantly alter the properties and structures of graphene-based devices, affecting their performance. Metal cations are commonly present in feeding solutions under pressure-driven separation conditions and can act as both target solutes and modifiers for graphene oxide (GO) membranes. This study reveals the influence of hydrated Na+/Mg2+ on the two-dimensional nanochannels of GO membranes under pressure-driven conditions. Hydrated Na+ expands the nanochannels, facilitating water molecules' passage, while hydrated Mg2+ reduces both the cross-sectional area and the number of transport pathways, increasing the transmembrane resistance of water molecules.

Summary: Electrochemical reduction of CO2 to valuable multi-carbon products is a potential solution to environmental and energy crises. In this study, N-heterocyclic carbenes (NHCs) incorporated into a graphene lattice were found to effectively activate CO molecules and convert them into CH3OH, C2H4, and C2H5OH with low limiting potentials. The catalytic performance of these NHCs is attributed to charge transfer and strong hybridization between NHCs and CO molecules, resulting in high activity and selectivity for the conversion of CO to valuable C2-products.

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.
