Single crystals of a new germanium clathrate, Ba 24 Ge 100 , were synthesized by the Czochralsky pulling method using a tetra-arc furnace under an Ar atmosphere. The crystal structure was studied by X-ray single-crystal analysis. The clathrate crystallized in the cubic space group P4 1 32 with a β«Ψβ¬

The epithelial lining of the mouth is the site of significant structural changes in the course of oral embryology and pathology. Invagination and differentiation of the ectodermal epithelium of the embryonic mouth initiates the development of the teeth, the salivary glands, as well as the anterior l
