Growth mechanisms of Ca- and P-rich MAO films in Ti-15Zr-xMo alloys for osseointegrative implants
In this study, a micro-arc oxidation treatment was applied to Ti-15Zr-xMo (x = 0, 5, 10 and 15 wt%) alloys to produce porous oxide layers enriched with bioactive ions (calcium and phosphorus) for use as osseointegrative ...
Study of SnO2 gels by Eu3+ fluorescence spectroscopy
Eu3+ fluorescence spectroscopy was used as a probe to study the changes in local arrangements of tin oxyhydroxide precipitate → sol → gel → glass conversion. Electronic transition intensities and 5D0 excited state lifetime ...

Nearly constant loss in crystalline oxide-ion conductor Gd2Zr2O7
We present a study of the nearly constant loss regime in the oxide-ion conductor Gd2Zr2O7 by using Impedance Spectroscopy measurements. At enough low temperature, between 173 and 253 K, the dielectric loss is found to be ...
Conducting behavior of crystalline a-PbO2 as revealed by DFT calculations
PbO2 is one material that has recently emerged as potential transparent conducting oxide for applications in the modern opto-electronic industry. In this work the electronic structure of the a-PbO2 polymorph has been ...
Thermal decomposition of crystalline Ni-II-Cr-III layered double hydroxide: A structural study of the segregation process
(Amer Chemical Soc, 2005-05-26)
A structural study of the thermal evolution of Ni0.69Cr0.31(OH)(2)(CO3)(0.155)(.)nH(2)O into NiO and tetragonal NiCr2O4 is reported. The characteristic structural parameters of the two coexisting crystalline phases, as ...
