Summary: The microstructure and properties of proton exchange membranes (PEMs) can be improved by adjusting the distribution modes of sulfonic acid groups. Different structures of sulfonated poly(arylene ether phosphine oxide)s (sPAEPO) with varying degrees of sulfonation were synthesized and it was found that the distribution modes of the sulfonic acid groups and the structural unit of diphenol monomer greatly affected the properties of the resulting PEMs. By adjusting the sulfonation degree, the comprehensive properties of the PEMs can be further improved.

Summary: In this study, we synthesized two types of poly(p-terphenylene alkylene)s containing perfluoroalkylsulfonic acid and perfluorophenylsulfonic acid, respectively, through superacid-mediated polyhydroxyalkylations and made proton exchange membranes (PEMs) out of them. Compared to Nafion 212, the PEM with perfluorophenylsulfonic acid groups (PTPF-Phenyl-SA) showed higher ionic conductivity and eight times lower vanadium (IV) permeation rate. The VRFB based on PTPF-Phenyl-SA exhibited longer self-discharge duration, high average coulombic efficiency of 99.6%, and lower capacity fade of 0.24% per cycle compared to Nafion 212.

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.
