Summary: The effects of ligand basicity on water and ion transport within hydrogel membranes are investigated using a library of functionalizable poly(ethylene glycol) diacrylate (PEGDA) polymer networks. The study reveals that the self-diffusion of water molecules and ions is primarily driven by the hydration level of the membrane. The interaction between triflate anions and the polymer significantly reduces ion and water mobility.

Summary: Interactions between organic pollutants and carbon-based particles are crucial for understanding their behavior in the environment. This study revealed the interactions between organics and biochars through experimental measurements and molecular dynamics simulations. The findings showed that biochars have different sorption performances for different organic compounds, and the sorption process is influenced by the surface and pores of the biochars. These results can guide the development of effective strategies for organic pollution control.

Summary: This study introduces a simple model combining physical partition and pseudo reaction equilibriums to accurately correlate various LLE systems, including immiscible, partially miscible, organic, and electrolyte systems. By fitting parameters, the model can accurately reflect intrinsic mechanism involving stoichiometric ratio of the pseudo reaction and total equilibrium constant for interaction intensity. The influence of solute, extractant, and temperature on parameters is also discussed, making this model promising for precise description of LLE systems and better understanding of their extraction mechanisms.

Summary: In this study, the effect of surfactant and etching time on the morphology of PSi matrix was investigated using a simplified two-electrode anodization cell with aqueous HF electrolyte. The rarely reported technique of potentiostatic anodization was used to regulate the surface morphology of PSi. The results showed that different PSi surface morphologies can be easily achieved by increasing the processing time or adding a small amount of surfactant under a constant applied potential.

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.
