Screen printed barium titanate thick films prepared from mechanically activated powders
(Trans Tech Publications Ltd, Durnten-Zurich, 2002)
Barium titanate thick films were prepared from mechanically activated powders based on BaCO3 and TiO2. The thick films were screen-printed on alumina substrates electroded with Ag/Pd. The BT films were sintered at 850 ...
Barium titanate screen-printed thick films
(Elsevier Sci Ltd, Oxford, 2002)
Barium titanate (BT) thick films were prepared from mechanically activated powders based on BaCO3 and TiO2. After homogenization and milling in a high-energy vibro mill, the powders were calcined at 700 degreesC for 2 h ...
A new procedure of phosphogypsum purification in order to diminish the content of radionuclides
(Hungarian Journal of Industrial Chemistry, 2002)
Phosphogypsum obtained by "wet procedure" for phosphoric acid production is actually calcium-sulphate dihydrate, CaSO 4 ·2H 2 O, which contains a high percent of impurities as well as radionuclides, originating from the ...
Study of corrosion resistance of chromium-nickel steel in calcium-hypochlorite solution
(Bulletin of Electrochemistry, 2002)
The purpose of this paper is to study the corrosion resistance of different samples bf chromium-nickel steel in calcium-hypochlorite solution, by potentiodynamic method. Corrosion resistance of Cr-Ni special steels is ...
Monoctonus leclanti sp n. (Hymenoptera : Braconidae : Aphidlinae) from high-montane areas of southeastern Europe, and key to related species
(Entomologica Fennica, 2002)
Monoctonus leclanti sp. n., a parasitoid of Delphiniobium junackianum Karsch. (Hemiptera: Aphididae) on Aconitum toxicum bosniacum and Aconitum pentheri in the high mountains of the Balkans is described. The species is an ...
Phase transformations and thermal effects of mechanically activated BaCO3 -TiO2 system
(Ferroelectrics, 2002)
Phase transformations and thermal effects of BaTiO 3 ceramics due to influence of mechanical activation were investigated. Equimolar mixture of BaCO 3 and TiO 2 powders was activated in high energy vibromill for various ...
New digital method of microstructural characterization of sintered materials
(Serbian Acad Sciences Arts, Belgrade, 2002)
Since a lot of physical properties of novel materials are determined by their microstructure it is very important to predict and control materials microstructure and its evolution, both in technological process of material ...
Potato Virus Y (PVY) on pepper in Serbia
(Int Soc Horticultural Science, Leuven 1, 2002)
During 1997, samples of plants showing symptoms of a viral disease were collected from thirteen pepper growing areas. On some plants characteristic symptoms of Potato Virus Y (PVY) infection were observed. Pepper samples ...
Inheritance of yield components in diallel crossing of divergent genotypes (Solanum melongena L.)
(Acta Horticulturae, 2002)
The aim of this study was to determine the mode of inheritance, the combining ability and the components of genetic variance for fruit weight and fruit number per plant in five divergent eggplant genotypes. The investigation ...
The effect of new herbicides on the grain yield of inbred lines of maize
(Fresenius Environmental Bulletin, 2002)
In these experiments, the reaction of 24 inbred lines of maize to the new herbicides Equip (formasulfuron), Callisto (mesotrione) and a combination of Motivel (nicosulfuron) with Banvel 480 S (dicamba) was investigated. ...
