Crystalline dipeptides: their molecular recognition to be useful to enantiomer separation,clusion crystals creates one of the most useful and informative fields of molecular recognition. Hitherto, the phenomena that host molecules form crystals with appropriate guest molecules have been investigated.1 Inclusion crystals of urea and bile acid were investigated at the early stage of this f作者: CRASS 時間: 2025-3-22 03:22 作者: 甜瓜 時間: 2025-3-22 04:53
Book 2004owadays, the descriptions “enantiomer resolution” or “enantiomer separation” are also commonly used. Accordingly, “Enantiomer Separation” is used in the title of this book. The editor and all chapter contributors hope that this book is helpful for scientists and engineers working in this field.作者: Eosinophils 時間: 2025-3-22 11:54
