Summary: The study introduces a low-cost, simple, and one-step synthesis method for cellulose acetate nanoparticles (CANPs) using a microfluidic reactor. The CANPs are self-organized in a microchannel by flowing cellulose acetate dissolved in N,N-dimethylformamide through the axial inlet and antisolvent water through the pair of side inlets, leading to in situ synthesis at the miscible interface. Subsequently, membranes with tunable properties are prepared, showing enhanced bactericidal properties and potential applications in health care and environmental remediation.

Summary: Natural gas production and utilization have increased significantly in recent years, necessitating improved methods for purification. This study focuses on the development of polymeric materials for natural gas purification and demonstrates that incorporating fluoroalkoxysilyl substituents can enhance CO2/CH4 permselectivity. The findings suggest that the observed increase in selectivity is primarily due to improved CO2 sorption in the fluorine-containing polymers.

Summary: This study aimed to develop a montmorillonite/magnetic NiFe2O4@amine-functionalized chitosan (MMT-mAmCs) composite as an adsorbent for the removal of cationic dyes from wastewater. The composite material exhibited high negative charges and ferromagnetic behavior, making it suitable for adsorbing the cationic contaminants. It showed promising adsorption capacity for methylene blue and crystal violet, and maintained satisfactory adsorption characteristics even after repeated use. Additionally, the MMT-mAmCs composite efficiently adsorbed dyes from real water samples, indicating its potential as a reusable adsorbent for cationic pollutants in aquatic environments.

Summary: This study investigated the permeation characteristics of CA/γ-CD-MOF mixed matrix membranes for CO2/CH4 separation, with defect-free membranes showing uniform dispersion of filler and high selectivity. Increasing filler weight percentage and pressure led to decreased permeability and selectivity for both gases, with the highest CO2/CH4 selectivity achieved by CA/γ-CD-MOF 0.4wt% MMM.

Summary: In this study, CoFe2O4/TiO2:Tb composite nanoparticles were synthesized by a chemical method, and it was found that there was a spin transfer between TiO2 and cobalt ferrite, resulting in ordered magnetic moments of oxygen vacancies in TiO2. The magnetic moments of Tb ions could have different coupling states depending on the dopant concentration, and the magnetically ordered interface transferred states helped increase the lifetime of photoexcited electrons.

Summary: Hybrid cellulose acetate nanofibers containing TiO2 were prepared using emulsion electrospinning technique for denitrification and filtration. The nanofibers showed excellent photocatalytic and filtration efficiency, with increased surface hydrophobicity due to the morphology of micro-wrinkles and protrusions. This suggests that TiO2-CA nanofibers could be promising materials for highly efficient and sustainable air filters in industrial and home appliance systems.
