Despite the topical action of colloidal bismuth subcitrate in promoting the healing of peptic ulcers, slight absorption of bismuth from the gastrointestinal tract has been reported in colloidal bismuth subcitrate-treated animals and man. The uptake and subcellular distribution of bismuth by the gastrointestinal tract of rats after 24 hours of colloidal bismuth subcitrate administration was stud...

This paper reports the synthesis of Bi1-xSmxFeO3 system (x = 0.00, 0.02, 0.04, 0.06, 0.08 and 0.10) obtained by thesolid-state reaction method at 1073.15 K for 15 h. Characterization allowed evaluating effect Sm3+ insertion on thestructural, morphological magnetic properties bismuth ferrite. Structural characterization was made X-rayDiffraction (XRD) Rietveld refinement, indicating formation a ...

X-ray diffraction imaging is rapidly emerging as a powerful technique by which one can capture the local structure of crystalline materials at the nano- and meso-scale. Here, we present investigations of the dynamic structure of epitaxial monodomain BiFeO3 thin-films using a novel full-field Bragg diffraction imaging modality. By taking advantage of the depth penetration of hard X-rays and thei...

Abstract The present research work reports on the fabrication of ultraviolet (UV) photodetectors using bismuth ferrite (BiFeO 3, BFO) thin films with varying thickness. Using spray pyrolysis technique, BFO were deposited glass substrate at 673 K. characterized by Raman and FTIR spectroscopic analysis. morphological analysis reveals uniform grain distribution for prepared samples. optical that t...

The coexistence of different ferroelectric phases enables the tunability macroscopic properties and extensive applications from piezoelectric transducers to nonvolatile memories. Here we develop a thermodynamic model predict stability low-energy orientations boundaries between in ferroelectrics. Taking lead zirconate titanate bismuth ferrite as two examples, demonstrate that interphase are larg...
