The relative viscosity ηr and, thus, the reduced viscosity ηsp/C of polymer solution could be obtained by recording the flow times of the polymer solution and the pure solvent in a capillary viscometer. Our experimental results indicated that the m

In this article, the influence of La substitution for Sr on structure and physical properties of the 2201 phase is studied. First, the crystal microstructure of the Bi2.1Sr1.9-xLaxCuOy (0 ≤ x ≤ 1.0) is characterized by means of x-ray diffraction

The microstructure of Bi 2 Sr 2-x Ba x CuO y (0≤x≤0.5) was characterized by transmission-electron microscopy and x-ray diffraction. Electron-diffraction analyses reveal that in the Bi-Sr-Cu-O system there also exists a c=12.5 A insulating phase w

The XRD analyses for the Bi-Pb-Sr-Ca-Ba-Cu-O system show that the addition of Ba ions is favourable to the formation of the higher-Tc phase (Tc>100 K), and TEM observations show that the partial substitution of Ba ions for Ca ions induces a change in
