Fabrication of Biaxially Aligned Nanofibers via Insulating Block-Assisted Electrospinning and Their Applications.

Electrospinning is a well-established and widely adopted process for producing fine and continuous nanofiber networks. Electrospun nanofibers have gained significant attention owing to their advantages, including nanoscale fiber uniformity, tunable pore size with bimodal distribution, and versatility in integrating various inorganic and organic compositions. Recently, considerable efforts have been made to align nanofibers and enhance their functionality with improved mechanical properties, faster charge transport, and more efficient mass transport in well-organized spatial structures.

Influence of nitrogen/phosphorus-doped carbon dots on polyamide thin film membranes for water vapor/N mixture gas separation.

Nanoparticles have been attracting attention because they can significantly improve the performance of membranes when added in small amounts. In this study, the effect of polyamide membranes incorporating hydrophilic nitrogen/phosphorus-doped carbon dots (NP-CDs) to enhance water vapor/N separation has been investigated. NP-CD nanoparticles with many hydrophilic functional groups are synthesized from chitosan by a one-pot green method and introduced to the surface of the polysulfone (PSf) substrates by interfacial polymerization reaction.
