Structural analysis of Zn2TiO4 doped with MgO
The starting mixtures of ZnO, TiO2, and MgO (0, 1.25, and 2.5 wt.%) powders are mechanically activated in a high-energy planetary mill for 15 min and then sintered between 800 and 1100°C for 2 h. The influence of MgO ...
Isothermal sintering of BZT ceramics
Starting mixtures of BaCO3 •ZnO and Ti02 were mechanically activated for 0,5, 10,20.40 and 80 minutes in a planetary ball mill. The powders obtained were sintered isothermally to temperatures between 1000 and 1300 °C. The ...
Citrate-based zinc-polyaniline secondary cell: Part I: Optimization of the citrate/chloride electrolyte
Electrochemical behavior of zinc and thin polyaniline (PANI) electrodes in citrate/chloride-contained electrolyte has been investigated by the means of electrolyte composition optimization. Electrolyte contained 0.8 M ...
Characterization of electrochemically synthesized PANI on graphite electrode for potential use in electrochemical power sources
(Materials Chemistry and Physics, 2009)
Polyaniline (PANI) on graphite electrode was synthesized electrochemically under galvanostatic condition at current density of 2.0 mA cm-2 from aqueous solution of 1.0 mol dm-3 HCl and 0.25 mol dm-3 aniline monomer. ...
Aktivnost alkalne fosfataze u kosti nakon implantacije nanočestičnog kalcijum-kobalt hidroksiapatita
(Beograd : Institut tehničkih nauka, 2009)
Istraživanje je sprovedeno sa ciljem da se dokaže aktivnost alkalne fosfataze, lokalizovane u dekalcifikovanoj kosti, uzete sa leve strane mandibule pacova, u kojoj je arteficijalno napravljen defekt i implantiran nano ...

The master sintering curves for BaTi0.975Sn0.025O3/BaTi0.85S n0.15O3 functionally graded materials
The most important aim in the design and processing of functionally graded materials (FGMs) is to produce devices free from any deformation. Smart choices of different combination of graded layers, as well as the heating ...
Influence of different degradation medium on release of ascorbic acid from poly(D,L-lactide-co-glycolide) nano- and microspheres
The major goals of the present study were to examine the effects of the type of release medium on the resulting drug release kinetics and to get further insight into the underlying drug release mechanisms. Spherical micro ...
Far infrared study of some rare earth impurities in crystals of Pb 1-xSnx alloys
(Bucharest : National R&D Institute for Optoelectronics, 2009)
Single crystal samples of Pb0.9Sn0.1Te doped with Yb, Sm or Gd were produced using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for highly polished samples with various impurity ...
