Summary: The study focused on enhancing boron removal performance of reverse osmosis (RO) membranes for seawater desalination by incorporating 2-hydroxyethyl acrylate (HEA) and acrylamide (AA) into m-phenylenediamine (MPD) solution. The addition of these compounds during ultraviolet (UV)-imported interfacial polymerization (IP) process resulted in the formation of a dense and tight hybrid separation layer structure. This structure enriched with hydroxyl groups could specifically interact with boric acid, leading to a significant increase in boron retention rate from 84.42% to 92.80%. Additionally, improvements in NaCl retention rate and water flux were observed in the modified membrane.

Summary: This study reported an innovative approach for controlling the polymerization process in the fabrication of thin film composite reverse osmosis membranes. The results showed that using a solvent mixture of toluene and n-hexane as the organic phase at a temperature of 20℃ significantly improved the salt rejection to 98.6% with a flux of 16.1 LMH. However, increasing the temperature further to 30℃ was not beneficial for membrane fabrication.

Summary: An amorphous phosphatized hybrid (a-Na3P/NaBr) artificial interface layer is developed to address the dendrite growth issue of sodium metal anode in sodium ion batteries. The modified sodium metal anode exhibits excellent cycling performance with an average Coulombic efficiency of 99.5% over 200 cycles under a capacity of 3 mAh cm-2. Furthermore, the modified sodium metal anode shows much superior performance compared to bare sodium metal anode even under a high depth of discharge of 50%, cycling for nearly 350 hours. These findings provide a promising avenue for the next-generation Na metal-based energy storage technologies.

Summary: The transport properties of a carbon molecular sieve (CMS) film in CO2-CH4 pure and mixed gases were studied. It was found that the CMS film had a lower CO2/CH4 mixed-gas solubility selectivity compared to glassy polymer films, and this selectivity increased with pressure. The presence of CO2 enhanced the diffusion coefficient of methane, indicating that CO2 diluted the sieving domains of the CMS matrix. As a result, the CMS film lost some of its size-sieving properties under mixed-gas conditions.

Summary: In this study, we investigated the separation performance of an ethanol-cyclohexane mixture using a thin-film composite membrane made of a heat-treated polyimide. We studied the chemical and structural transformations that occur during the formation of thermally-rearranged and carbon molecular sieve membranes, which significantly impact the properties and separation behavior of the membrane. We achieved excellent separation performance by precise thermal treatment, and highlighted the unique property of pervaporation where the downstream side of the membrane remains dry despite swelling in the upstream region.

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.
