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).
