Speciation of selected trace and major elements in lignite used in 'Nikola Tesla A' power plant (Obrenovac, Serbia) / Specijacija odabranih mikro- i makroelemenata u uzorcima lignita termoelektrane 'Nikola Tesla A' (Obrenovac, Srbija)
(Serbian Chemical Society, 2005)
Four samples of milled lignite used in the "Nikola Tesla A" power plant located in Obrenovac near Belgrade, were subjected to a five-step sequential extraction, comprising of the following phases: distilled water, 1M ...
Layered crystal structure of the trans(O5O6) isomer of potassium (1,3-propanediamine-N,N '-diacetato-N,N '-di-3-propionato) cobaltate(III) trihydrate, trans(O5O6)-K[Co(1,3-pddadp)] center dot 3H(2)O, stabilized by ionic, hydrogen bond and C=O dipolar inte
(Oxford : Pergamon-Elsevier Science Ltd, 2005)
The hexadentate trans(O5O6)-K[Co(1,3-pddadp)] (.) 3H(2)O complex (where 1,3-pddadp represents the 1,3-propanediamine-N,N'-diacetate-N,N'-di-3-propionate ion) has been characterized by single-crystal X-ray crystallography. ...
Leaching of selected elements from coal ash dumping
(Springer Berlin Heidelberg, 2005)
Coal ash obtained by coal combustion in the "Nikola Tesla A" power plant in Obrenovac near Belgrade (Serbia) is suspended in river water then carried by a pipeline to a dump. In order to predict the ...
Differentiation of the contribution of local resuspension from that of regional and remote sources on trace elements content in the atmospheric aerosol in the Mediterranean area
(Oxford : Pergamon-Elsevier Science Ltd, 2005)
For the determination of effects of contaminated crude soil on the content of trace elements in the atmospheric aerosol, trace elements in crude soil samples from within the area of influence of local resuspension were ...
Characterization of glycidyl methacrylate based copolymers by inverse gas chromatography under finite surface coverage
(Wiley-V C H Verlag Gmbh, Weinheim, 2005)
Inverse gas chromatography under finite surface coverage conditions (IGC-FC) was used for the investigation of sorption of hexane, benzene, chloroform and tetrahydrofuran on macroporous crosslinked poly[(glycidyl ...
Characterization and catalytic activity of poly(4-vinylpyridine-co-divinylbenzene)-Co2+ complex
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
Poly(4-vinylpyridine-co-divinylbenzene)-Co2+ was characterized using infrared spectroscopy (IR), thermogravinietric analysis (TG-DTA), N-2-physisorption and polarography. Thermal analysis suggests sufficient thermal stability ...

The influence of concentration of Nd-Fe-B powder in composite coating of optical fiber to the sensibility to external magnetic field
(Technical Faculty, Bor, 2005)
Multi-mode optical fiber with magnetic composite coating was investigated as an optical fiber sensor element (OFMSE) for magnetic field sensing The composite coating was formed with dispersions of permanent magnet powder ...
Characterization of the catalysts by means of an oscillatory reaction
(CRC Press, 2005)
One of the most known physical chemists Wilhelm Ostwald defined catalyst as a substance that participates in a particular chemical reaction and thereby increases its rate but without a net change in the amount of that ...
