Journal ArticleDOI
Layered structures of vanadium pentoxide gels
TL;DR: In this paper, the 3D structure of V 2 O 5 gels was studied by means of the X-ray Rietveld method from a series of 00l reflections.
Journal ArticleDOI
Protonic conduction and defect structures in Sr-doped LaPO4
TL;DR: In this article, a defect structure model for Sr-doped LaPO 4 was proposed, which showed that in wet atmosphere, protons are introduced into the phosphate forming hydrogen phosphate groups through the equilibrium between P 2 O 7 4− and water vapor.
Journal ArticleDOI
Hydrothermal Synthesis of Lanthanum Vanadates: Synthesis and Crystal Structures of Zircon-Type LaVO4 and a New Compound LaV3O9
TL;DR: In this paper, single-crystal X-ray diffractometry confirmed the zircon-type structure for LaVO 4 : I 4 1 / amd with a =7.4578(7) A, b =9.949(2) A and c =6.5417(9) A. The structure consists of isolated VO 4 tetrahedra which surround the La atom to form a LaO 8 dodecahedron.
Journal ArticleDOI
Crystal Structures and Transition Mechanism of VO2(A)
TL;DR: In this article, the structure of VO2(A) has been determined by single-crystal diffractometry for low- (LTP) and high-temperature (HTP) phases at 298 and 473 K, respectively.
Journal ArticleDOI
Powder X-ray crystal structure of VO2(A)
TL;DR: In this article, the powder X-ray structure analysis of VO2(A) has been performed by the use of EXAFS and the Rietveld method; possible structure models based on the ex-AFS results were examined by the Rieveld analysis.
