Hydroxycarbonate precursors with different Cu/Zn/Co/Cr atomic ratios and CuZnCoCr oxides obtained by thermal treatment of the precursors at different temperatures (623, 723, and 973 K in air) have been examined. Characterization has been per

Samples of CuCo mixed oxide with Cu Co = 0.25 to 1.0 (atomic ratio) were prepared by coprecipitation with Na2CO3 and were characterized with TG, DSC, XRD, and XPS. Exothermic DSC peaks were observed at 588 and 808 K for Cu Co = 0.25 , and at 588,

Here, we report on a size-controlled synthesis of highly crystalline germanium particles, via the self-sustained reaction of GeO2 with Zn, Mg, and NaBH4. The thermodynamic analysis suggests that the GeO2 + 2Zn and GeO2 + NaBH4 systems are characteriz

We present in this paper the structural and magnetic properties of high aspect ratio Co nanoparticles (~10) at high temperatures (up to 623 K) using in situ X ray diffraction (XRD) and SQUID characterizations. We show that the anisotropic shapes, the

Synchrotron X-ray powder diffraction patterns were collected at the European Synchrotron Radiation Facility (ESRF, Grenoble, France) on powder samples of PbTiO3 (tetragonal, Z=1 P4mma=3.9036(1) A and c=4.1440(2) A at room conditions) applying externa

In a previous communication, it was shown that the precipitate obtained from mixed nitrate solution of Cu, Zn, and Al is more or less monophasic in which Al{sup 3+} ions have been incorporated in the aurichalcite (Cu, Zn){sub 5}(CO{sub 3}){sub 2}(OH)
