چکیده

Barium dierbium(III) tetra-sulfide, BaEr2S4, crystallizes with four formula units in the ortho-rhom-bic space group Pnma in the CaFe2O4 structure type. The asymmetric unit contains two Er, one Ba, and four S atoms, each with .m. site symmetry. The structure consists of channels formed by corner- and edge-sharing ErS6 octa-hedra in which Ba atoms reside. The resultant coordination of Ba is that of a bicapped trigonal prism.

Early Results of the Use of Acellular Dermal Allograft in Type III Paraesophageal Hernia Repair

BACKGROUND Type III paraesophageal hernias are diaphragmatic defects with the risk of serious complications. High recurrence rates associated with primary suture repair are significantly improved with the use of a tension-free repair with prosthetic mesh. However, mesh in the hiatus is associated with multiple complications. A bio-engineered material from donated human tissue offers an attracti...

The title compound, {[Er2(C4H2O4)2(C2O4)(H2O)4]·4H2O} n , was synthesized by the reaction of erbium nitrate hexa-hydrate with fumaric acid and oxalic acid under hydro-thermal conditions. The Er(3+) cation (site symmetry ..2) is eight-coordinated by six O atoms from four fumarate anions (site symmetry ..2) and one bidentate oxalate anion (site symmetry 222), and by two water mol-ecules. The comp...
