Enantioseparation of Novel Chiral Tetrahedrane-Type Clusters on an Amylose Tris (Phenylcarbamate) Chiral Stationary Phase

SummaryAmylose tris(phenylcarbamate) (ATPC) coated on a small particle silica gel was prepared. This ATPC chiral stationary phase (ATPC-CSP) was found to be useful for the enantiomeric separation of some novel chiral tetrahedrane-type clusters. Moreover, the influence of mobile phase modifier and of the structure of chiral tetrahedrane-type clusters on the chiral separation and retention were investigated. The results suggest that not only the structure and concentration of alcohol in mobile phase, but also the subtle structural differences in racemates can have a pronounced effect on enantiomeric separation and retention.

Research of bus station architecture based on smart space

The concept of intelligent transportation has been accepted by the society, and has been widely applied. At the same time, the application of information tools such as smart space has changed the current backward bus station vehicle management mode. Improving the bus station vehicle management level, operation efficiency and city public traffic service level will be the developing direction of government support in the future. This paper introduce the definition, characteristics, functions and composition of smart space briefly. On this basis, we put forward the conception of bus station based on smart space detailed, and analyzed its function. Finally, we built the bus station architecture in the smart space environment.
