5S Elements as steps to bridge the gap in transmitter manufacturing process / 5S elementi kao koraci za premošćivanje procepa u procesu prozvodnje transmitera
(Zrenjanin: University of Novi Sad - 'Mihajlo Pupin' Technical Faculty, 2019)
In this paper, GAP analysis and 5S tool are applied in the case of realization of a compact pressure
transmitter. GAP analysis, combined with the 5S tool, can qualitatively indicate the critical points
in the manufacturing, ...
Catalytic effect of sulphuric acid in the process of deposition of chromium coatings / Katalitički uticaj sumporne kiseline u procesu taloženja prevlaka hroma
(Belgrade, Serbia : Engineering Society for Corrosion, 2011)
This paper analyzes the catalytic effect of sulphuric acid on current efficiency, the coating thickness and the rate of deposition of electrochemical chromium coatings. According to the properties of chrome, there are three ...

(Belgrade, Serbia : Engineering Society for Corrosion, 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. ...
The synthesis of CaO loaded onto Al2O3 from calcium acetate and its application in transesterification of the sunflower oil / Sinteza CaO nanešenog na Al2O3 od prekursora kalcujum acetata i njegova primena u transesterifikaciji suncokretovog ulja
(Tehnološki fakultet, Leskovac, 2015)
Transesterification of sunflower oil was carried out over CaO loaded onto γ-Al2O3 as heterogeneous base catalysts. The solid base catalysts were synthesized by the modified wet impregnation of calcium acetate monohydrate ...
Hydroxyapatite coatings on TiO2 nanotubes / Prevlake hidroksiapatita na nanotubama oksida titana
(Belgrade, Serbia : Engineering Society for Corrosion, 2010)
The aim of this work was to obtain nanotubular TiO2 layer by anodization of titanium substrate, and to prepare hydroxyapatite (HAP) coatings by electrophoretic deposition over nanotubular TiO2 layer. The presence of fluoride ...
Landfills on the banks of Timok from Zaječar to the mouth of Danube / Deponije na obalama Timoka od Zaječara do ušća u Dunav
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2011)
Timok is created by merging the Black and White (Knjaževac) Timok in Zaječar, and then, after a course of about 85 km, flows into the Danube. Timok flows besides several small settlements, it has more meanders, and at last ...
Revitalization and development of facilities for production of higher order petrochemical derivatives: Precondition for survival of Serbian petrochemical industry / Revitalizacija i razvoj proizvodnje derivata više faze dorade - preduslov opstanka Srpske petrohemijske industrije
(Institut za istraživanja i projektovanja u privredi, Beograd, 2009)
Development of petrochemical industry in Serbia has started in the early 70s of the last century. By disintegration of Yugoslavia the dimension of 'domestic' market for petrochemicals was first drastically reduced, what ...
Comparison of morphology of powder particles obtained by the constant and periodically changing regimes of electrolysis / Poređenje morfologije čestica praha dobijenih konstantnim i periodično promenljivim režimima elektrolize
(Belgrade, Serbia : Engineering Society for Corrosion, 2011)
Morphologies of copper powder particles obtained by both potentiostatic and pulsating overpotential (PO) regimes of electrolysis were analyzed using the technique of scanning electron microscopy (SEM). The parameters of ...
