Application

  • Biodepolymerization of Polyamide Fibers Using Yarrowia lipolytica as Whole-Cell Biocatalyst: This study explores the synthesis of Polyamide-6,6 by polycondensation of two initial monomeric units adipic acid and hexamethylenediamine (FS Buarque et al., 2024).
  • Interfacial Hydrogen Bond Effect Between CeO2 and g-C3N4 Boosts Conversion to Adipic Acid from Aerobic Oxidation of Cyclohexane: This research highlights how the interfacial hydrogen bond effect between catalysts can improve the aerobic oxidation of cyclohexane to adipic acid, a significant step towards sustainable adipic acid production (K Li et al., 2024).
