Order—Disorder transformation and its effect on the properties of (Lanthanide)2Zr1.5Hf0.5O7 functional nanoceramics

Order disorder transformations and its effect on the structural, optical and ionic transport properties of the cubic pyrochlore – defect fluorite structures are the prime focus of this study. Nanoceramics of Ln2Zr1.5Hf0.5O7 (Ln = Pr, Nd, Sm, Gd, Dy and Er) are prepared through the modified combustion technique. X – ray diffraction analysis and electron microscopic studies show the cubic nano crystallite nature of the materials. Vibrational studies reveal the pyrochlore–fluorite phase transformation in the series. Highly dense bulk ceramics are prepared from the nano particles at relatively low temperatures. The gradual replacement of Ln3+ ions in Ln2Zr1.5Hf0.5O7 changes the pyrochlores (Ln = Pr-Sm) to defect fluorite (Ln = Er) through the weakly ordered defect fluorites (Ln = Gd and Dy). Impedance spectroscopic analysis carried on the bulk ceramics shows the influence of phase transformation on the oxide ion conduction of bulk materials. The peak oxide ion conduction is observed for the Ln = Dy ceramic, which is at the pyrochlore fluorite phase boundary.

Synthesis of Samarium, Europium, and Ytterbium Acetylides

Ethynyl complexes of samarium, europium, and ytterbium were obtained by the reaction of naphthalides of these metals with acetylene in tetrahydrofuran. The complexes were isolated as dark-colored pyrophoric powders. Magnetic data indicate that Sm(II) is oxidized into Sm(III) completely in the course of the reaction, Yb(II) is partially converted into Yb(III), whereas europium retains its initial bivalent state. Hydrolysis of thecompounds obtained yields acetylene, ethylene, ethane, and hydrogen, wh ich indicates the presence of the Ln-C.tplbnd.C-Ln acetylide and the Ln-H hydride groups (Ln=Sm, Eu, and Yb).

Acid Solvolysis Kinetics of Lanthanide Porphyrins

The kinetics of the acid solvolysis reactions of twelve water-soluble lanthanide tetrakis(N-methyl-4-pyridyl)porphyrins (Ln-P) follow rate = k1+>2/ (k-1/k2) + +>> at 25 deg C, I = 0.8M (LiNO3/HNO3) indicating that two protons are required for solvolysis, and since log (k1k2/k-1) = 45.0R0 - 39.4 (R0 is the ionic radius in Angstroem), a 0.1 Angstroem change in radius has a 32000 fold rate effect.
