Development of a Kinetic Model for Catalytic Reforming of Naphtha and Parameter Estimation Using Industrial Plant Data
(Amer Chemical Soc, Washington, 2009)
In the present paper, a semi-empirical kinetic model for catalytic reforming has been developed. In the developed model, the component "lumping" strategy is based on a paraffins, olefins, naphthalenes, and aromatics (PONA) ...
Characterization of electrochemically synthesized pani on graphite electrode for potential use in electrochemical power sources / Elektrohemijska sinteza i karakterizacija elektrode od polianilina za potencijalnu upotrebu u elektrohemijskim izvorima energije
(Inženjersko društvo za koroziju, Beograd, 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 moldm-3 HCl and 0.25 mol dm-3 aniline monomer. ...
Determination of multiple pharmaceutical classes in surface and ground waters by liquid chromatography-ion trap-tandem mass spectrometry
(Elsevier Science Bv, Amsterdam, 2009)
This paper describes development, optimization and application of analytical method for determination and reliable confirmation of nineteen pharmaceuticals from different therapeutic classes (antibiotics-beta-lactams. ...
The corrosion stability of epoxy cataphoretic coatings on steel and steel coated with zinc alloys
(Corrosion Protection: Processes, Management and Technologies, 2009)
An organic coating is frequently deposited on the top of the metallic coating in order to generate a corrosion resistant system by taking advantage of the good properties of the sublayer. In automotive industry steel is ...

Acceptability of Residual Stresses Measurement Methods of Butt Weldments and Repairs
(Strojarstvo, 2009)
The joints made by fusion of materials are exposed to the influence of residual stresses induced by welding thermal cycles. Residual stresses were measured on butt welded plates made of NIOMOL 490K, before and after ...
Linear free energy relationships of the H-1 and C-13 NMR chemical shifts in 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)pyridones
(Elsevier Science Bv, Amsterdam, 2009)
Linear free energy relationships (LFER) were applied to the H-1 and C-13 NMR chemical shifts in 3-cyano-4(substituted phenyl)-6-phenyl-2(1H)pyridones. The correlation analysis for the substituent-induced chemical shifts ...
Mass transfer and fluid flow visualization in packed and fluidized beds by the adsorption method
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Mass transfer coefficient (j (D) ) between fluid and column wall in liquid packed and fluidized beds of spherical inert particle has been studied experimentally using adsorption method. Experiments were conducted in column ...
Investigation of biocompatibility of alpha-tricalcium phosphate: Test for primary cutaneous irritation / Ispitivanje biokompatibilnosti alfa-trikalcijum fosfata - test primarne kutane iritacije
(Univerzitet u Beogradu - Medicinski fakultet, Beograd, 2009)
Objectives. The aim of this study was to determine the irritant properties of alpha-tricalcium phosphate, a new calcium phosphate ceramic material, after single application to intact skin of the rabbit. Methods. As a ...
Determination of inorganic anions in papermaking waters by ion chromatography
(Journal of the Serbian Chemical Society, 2009)
A suppressed ion chromatography (IC) method for the determination of inorganic anions in process water from paperboard production was developed and validated. Common inorganic anions (Cl(-), NO(3)(-), PO(4)(3-) and SO(4)(2-)) ...
