Summary: We developed a thin-film-composite hollow fiber membrane with a hydrophilic active layer and a hydrophobic substrate for concentrating KAc solutions. To overcome the problem of liquid water crossover, a hydrophobic substrate was chosen. The deposition of hydrophilic macromolecules on a hydrophobic surface was achieved by using methanol as a co-solvent and pre-coating dopamine as a hydrophilic binding layer. The resulting membrane showed stable performance in concentrating KAc solutions, with a stable water flux and high salt retention.

Summary: PVDF aerogels with tailorable phase composition were prepared by following the crystallization-induced gelation principle. The non-solvent concentration was adjusted to control the crystalline composition of the aerogels, resulting in low-density aerogels with valuable phases. The phases of the aerogels were monitored using techniques such as FTIR, Raman spectroscopy, and ATR-FTIR spectroscopy. SEM and SR-μCT showed that the aerogels had variable particle morphologies depending on the non-solvent composition.

Summary: A new uranium adsorbent, poly(tetraethylenepentamine-trimesoyl chloride), was synthesized for uranium adsorption in water. The samples were characterized using SEM, EDS, TGA, FTIR, and XPS, and the removal ability and adsorption mechanism of uranium (VI) in an aqueous solution were systematically studied. The results showed that the adsorption equilibrium was reached within 80 minutes, with an adsorption capacity of 189.82 mg g(-1) and a removal rate of 94.91%. The adsorption process followed the pseudo-second-order model and Langmuir isotherm model. Thermodynamic analysis indicated that the adsorption was endothermic and spontaneous. This study demonstrated that poly(tetraethylenepentamine-trimesoyl chloride) is a highly efficient and sustainable material for removing uranium (VI) from aqueous solutions.

Summary: In this study, the performance outputs of triboelectric nanogenerators (TENGs) were enhanced using polyvinylidene fluoride (PVDF)/fullerene (C-60) composite nanofibers (NFs). It was found that the incorporation of C-60 into the PVDF matrix improved the output power of the TENG devices, but an excessive amount of C-60 resulted in a decrease in power. The increase in C-60 content in the PVDF matrix enhanced the TENG performance by improving trap charge ability and electronegativity, and the output power was sufficient to operate a display device.

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.
