Abstract:
Two novel heptanuclear 3d-4f helicates have been synthesized and characterized. The helicates act as catalysts and show high catalytic activity for the coupling of CO2 and epoxides to obtain cyclic carbonates with a wide substrate scope at ambient temperature and pressure.

Fixation and Sectioning
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...
