Dielectric and relaxor behavior of BaBi4Ti4O15 ceramics
(Elsevier Science Sa, Lausanne, 2010)
Barium bismuth titanate BaBi4Ti4O15 (BBiT) ceramics have been prepared using non-conventional solid-state reaction route based on mechanochemical synthesis during intensive milling. The X-ray diffraction method was used ...
The characterization of the barium titanate ceramic powders prepared by the Pechini type reaction route and mechanically assisted synthesis
(Elsevier Sci Ltd, Oxford, 2010)
BaTiO3 ceramic powders were prepared by a complex method based on the Pechini type reaction route and mechanically assisted synthesis. In both ways BaTiO3 ceramics were sintered after 120 min on 1300 degrees C without ...

Role of antioxidant enzymes in the seasonal adaptation of Picea omorika (Pančić) Purkyne
(PMF, University of Niš, 2010)
We studied seasonal variation in the achv1ty and isoenzyme pattern of peroxidase, catalase, catechol oxidase and superoxid-dismutase in the needles of Picea omorika (Pancic) Purkyne trees. The samples were collected from ...
Properties of MnZn ferrites prepared by powder injection molding technology
(Elsevier Science Bv, Amsterdam, 2010)
In this work, manganese zinc ferrite components were manufactured by powder injection molding-PIM technology. A fine powder consisting of Mn1-xZnxFe2O4 with small addition of hematite alpha-Fe2O3 as used in mass ferrite ...
Dielectric investigations of La-doped barium titanate
(Faculty of Technology, University of Novi Sad, 2010)
In the present paper results of the dielectric investigation of barium titanate (BaTiO3) doped with different
concentrations of lanthanum are presented. Ceramic samples were prepared by the Pechini process. With ...
Application of pulsating overpotential regime on the formation of copper deposits in the range of hydrogen co-deposition
(Springer, New York, 2010)
Electrodeposition of copper by pulsating overpotential (PO) regime in the range of hydrogen co-deposition was examined by scanning electron microscopy. It was found that the increase of the pause-to-pulse ratio produced a ...
