Electrodeposition and electroless deposition of metallic powders: A comparison
(ECS Transactions, 2011)
Electrodeposition and electroless deposition of metallic powders were comparatively investigated. Electrodeposition of copper is accompanied with the simultaneous hydrogen evolution, which significantly influences the ...
Degradation of organophosphorus insecticide by chlorine dioxide / Degradacija organofosfornog insekticida pomoću hlor-dioksida
(Serbian Chemical Society, Belgrade / Srpsko hemijsko društvo, Beograd, 2019)
In this paper, the degradation of organophosphorus insecticide (malathion) with chlorine dioxide was investigated. Degradation was studied in deionized water. Optimization of degradation conditions was examined under light ...
Two step sintering of the ZnTiO3 nanopowder
(Belgrade : Institute for Multidisciplinary Research, University of Belgrade, 2015)
Metastabile nanopowder ZnTiO3 pressed into cylindrical compacts at 200 MPa was submitted to conventional heating with isothermal holding at 931oC for 10 minutes, 25 minutes and 40 minutes. Same compacts were heated with ...
Possible Mechanism of Pectin-Derived Oligosaccharides Influence on Gut Microbiota / Predloženi mehanizam uticaja oligosaharida dobijenih iz pektina na intestinalnu mikrobiotu
(Belgrade: University of Belgrade, 2018)
We prepared pectin-derived oligosaccharides (apple and citrus) and polygalacturonic acid-derived oligosaccharides, using alkaline hydrolysis by hydrogen peroxide, and analyzed them by Fourier Transform Infrared spectrometry. ...
Humidophila brekkaensoides (Bock) Lowe, Kociolek, J.R.Johansen, Van de Vijver, Lange-Bertalot & Kopalová : aerophytic diatom from the caves of Serbia
(Bulgarian Federation of Speleology, 2019)
Diatom Humidophila braekkensoides is rare,
aerophytic species found in seven caves of Serbia.
First time was found at Alp’s rock in thin layer
and described as a species that prefer non
calcareous substratum. Our results ...
Design and testing characteristics of thin stainless steel diaphragms
(Elsevier, 2018)
Metal membranes are defined as thin steel circular plates. The metal membranes are widely used in the measurement technique and they are constantly loaded over the entire surface. In case that a membrane is loaded with ...
Electrochemical behavior of polyaniline in chloride/citrate electrolyte
(Tatranské Matliare : Slovak Society of Chemical Engineering, 2011)
Polyaniline electrode, was obtained by electrochemical polymerization at constant current density of 2.0 mA cm-2 from aqueous solution of 1.0 mol dm-3 HCl containing 0.25 mol dm-3 aniline. Electrochemical characterization ...
Oxidation of formic acid on bulk and nanosized Pt-Co alloys
(Serbian Chemical Society, Belgrade, 2010)
Bulk Pt3Co and nanosized Pt3Co and PtCo alloys supported on XC-72 high area carbon were investigated as the electrocatalysts for the oxidation of formic acid. Cyclic voltammetry in 0.1 M HClO4 and stripping voltammetry of ...
Effect of parameters of pulsating current (PC) regimes on morphology of electrodeposited copper in hydrogen co-deposition range
(Serbian Chemical Society, Belgrade, 2010)
The most often employed electrolytes for the electrodeposition of copper are those based on aqueous solutions of sulfuric acid (H2SO4) and cupric sulfate (CuSO4). There is an ionic equilibrium of a lot of species in the ...
Osetljivost na teške metale i rast na aromatičnim jedinjenjima bakterijskih sojeva izolovanih iz zemljišta kontaminiranog naftnim derivatima / Sensitivity to heavy metals and growth on aromatic compounds of bacterial strains isolated from soil contaminated with petroleum products
(Belgrade : Serbian Chemical Society, 2013)
Aromatični ugljovodonici dospevaju u životnu sredinu na različite načine, kao što su izlivanje nafte, sagorevanje fosilnih goriva, upotreba pesticida, curenje benzina. Pošto su toksični i potencijalno karcinogeni, razvijaju ...
