One of the current bottlenecks in developing OSN is materials stability in the solvent. To understand the interior structure and transport of OSN being used in different solvents are helpful to have an insight of its fundamendal separation mecahnisms and to design better solvent resistant membranes. State-of-the-art analytical insturment (positron annihilation spectroscopy, PAS) and computer simulation (molecular dynamics, MD) would be used to facilitate the study of OSN stability in this joint project.有機溶劑奈米過濾複合膜鑑定正子消散時間光譜分析Organic Solvent Nanofiltration (OSN)Composite MembraneCharacterizationPositron Annihilation Spectroscopy (PAS)
