Summary: Cellulose nanocrystals (CNC) obtained from waste sawdust were used to modify the polyamide membrane, resulting in improved mechanical strength and stability. The modification of the membrane was confirmed by changes in zeta potential and X-ray photoelectron spectroscopy (XPS). The presence of CNC reduced the degree of crosslinking and enhanced the membrane's robustness in acidic and alkaline solutions, as indicated by increased Young's modulus, maximum load, and tensile strength.

Summary: In this study, machine-learned interatomic potentials were used to accurately predict the structural and dynamical properties of dry and hydrated perfluorinated ionomers. Molecular dynamics simulations revealed the formation of hydrophilic and hydrophobic domains in this material, as well as the diffusion coefficients of protons and water molecules under various humidity conditions. Grotthuss chains consisting of two to three water molecules were found to significantly contribute to the high proton mobility under strongly humidified conditions.

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.
