The structure of the oxygen-deficient compound 7Bi 2 O 3 β’2WO 3 , a fluorite-derivative phase considered a candidate for electronic applications because of its high ionic conductivity, is investigated by singlecrystal X-Ray diffraction employing Ag-KΞ± radiation (Ξ» = 0.5608 Γ ) to minimize the effect
## Abstract **Summary:** The fullβprofile refinement of Xβray diffraction patterns was used to investigate two poly(thiodiethylene terephthalate) (PSDET) samples with different thermal history in order to thoroughly analyze their polymorphic aspects. In each sample, a crystalline (__Ξ±__ or __Ξ²__) a
