Summary: Developing a high-performance composite membrane with excellent flexibility for dye filtration is a challenge. Polypyrrole nanotubes (PPy-NTs), polypyrrole nanotubes/C (PPy-NTs/C), and polypyrrole nanotubes/ C/TiO2(PPy-NTs/C/TiO2) modified porous poly(ether sulfone) membranes were prepared for ultrafiltration of Evans blue anionic dye (EB). Under optimal conditions of pH = 7 and 25 degrees C, the elimination percentage of EB dye reached up to 99%. The Freundlich isotherm model provided the best fit to the experimental data (R2 = 0.9974).

Summary: Thermo-sensitive microgels called PMO-MGs were synthesized and used to prepare composited ultrafiltration membranes with improved surface hydrophilicity and antifouling performance. The PMO-MGs were spherical in shape and had an average diameter of 323±12 nm. The addition of PMO-MGs also imparted thermo-sensitive characteristics to the membranes, with an increase in pure water flux from 369.7 to 618.7 L·m(-2)·h(-1) as the temperature increased from 20 to 45°C.

Summary: The non-isothermal crystallization behaviors and kinetics of poly(phthalazinone ether sulfone) (PPES)/MC nylon 6 composites were studied using differential scanning calorimetry (DSC). The inclusion of PPES increased the crystallinity of MC nylon 6, but the crystallization rate decreased. PPES acted as a nucleating agent and restricted the movement of chain segments during crystal growth.

Summary: A novel hybrid material composed of graphene oxide (GO) and graphitic carbon nitride (g-C3N4) nanosheets was fabricated to improve the tribological performance of poly (phthalazinone ether sulfone ketone) (PPESK). The microstructure of GO/g-C3N4 was studied by varying the mass ratio of GO to g-C3N4, and the ratio of 1:2 (GO/g-C3N4-2) showed the best distribution and active sites. The GO/g-C3N4 hybrid, especially GO/g-C3N4-2, exhibited superior reinforcing and lubricating effects compared to single GO and g-C3N4. Additionally, the addition of 0.1 wt% GO/g-C3N4-2 improved the antifriction and anti-wear performance of PPESK by 77.28% and 96.9%, respectively. The enhancement mechanisms of GO/g-C3N4 on the tribological behaviors of PPESK were clarified by analyzing the surface morphology.

Summary: The crystalline structures and transitions of PPES/MC nylon 6 composites were studied using WXRD and FTIR spectroscopy. WXRD analyses showed that raising the annealing temperature transformed the quenched samples from γ-form crystals to α-form crystals. Increasing the PPES content promoted the γ→α form transition, facilitating crystallization in the stable α-form crystal. FTIR analyses indicated that treating the pristine samples with aqueous I/KI transformed the α-form crystals to γ-form crystals. The inclusion of PPES hindered the α→γ form transition, promoting crystallization in the stable α-form crystal. Two consistent observations were made: PPES favored the α-form crystal in PPES/MC nylon 6 composites, and the crystalline transition mechanism involved the strong interactions between PPES and MC nylon 6 through anchored antiparallel chains hydrogen bonding of the α-form crystal.

Summary: In this study, a renewable and robust solar steam generator was fabricated for dye wastewater purification. This generator achieved a high evaporation rate and demonstrated the ability to purify wastewater with different dye concentrations. It also exhibited good stability and mechanical properties. The blocked generators after long-term treatment of high concentration wastewater can be regenerated by calcination, solving the issue of decreased evaporation rate due to organic accumulation. This work holds great practical application potential for organic wastewater purification.

Summary: Hierarchical AlPO-34 molecular sieves microspheres were successfully synthesized in a [BMIm]Br ionic liquid without the need for a template or complex post-treatment process. The [BMIm]Br was shown to act as both a solvent and a structure directing agent. The organic amine in the compound affected the framework density of the crystals and promoted the formation of a chabazite (CHA) type framework. The resulting microspheres had a high surface area and a uniform mesoporous channel network.

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.
