Description

Application

• 
  Enhancement of Polyamide Nanofiltration Membranes: Piperazine anhydrous was utilized to refine polyamide nanofiltration membranes, focusing on reducing pore size distribution through a one-step multiple interfacial polymerization technique. This method significantly enhances the membrane′s antifouling capabilities, important for applications in water treatment and chemical separation (Liu et al., 2022).
  


• 
  Ultrasonic synthesis of stable oil filled microcapsules: This study explores the ultrasonic synthesis of oil-filled microcapsules using thiolated chitosan, potentially involving derivatives like ᴅʟ-N-Acetylhomocysteine thiolactone for improved stability and functional properties. The research provides insights into advanced microencapsulation techniques relevant in pharmaceutical and industrial applications (Source).
