Development of ion chromatography methods for the determination of trace anions in ultra pure water from power plants / Razvoj metoda jonske hromatografije za određivanje tragova anjona u ultra čistim vodama iz termoelektrana
(Serbian Chemical Society, Belgrade, 2005)
A suppressed ion chromatography (IC) technique, using a carbonate/hydrogen carbonate or a hydroxide eluent, has been evaluated as a monitoring tool for the detection of major anions (F-, Cl-, NO3-, PO43- and SO42-) in ultra ...
An experimental study of the partial oxidation of ethane to ethylene in a shallow fluidized bed reactor / Eksperimentalno ispitivanje parcijalne oksidacije etana do etilena u reaktoru sa plitkim fludizovanim slojem
(Serbian Chemical Society, Belgrade, 2007)
The partial catalytic oxidation of ethane to ethylene was investigated experimentally in a shallow fluidized bed. The performances of two catalyst types, pure γ-Al2O3 and V2O5/γ-Al2O3 particles 1.8 mm in diameter, were ...
Alkylation of N-substituted 2-phenylacetamides: Benzylation of N-(4-chlorophenyl)-2-phenylacetamide / Alkilovanje n-supstituisanih 2-fenilacetamida: Benzilovanje n-(4-hlorfenil)-2-fenilacetamida
(Serbian Chemical Society, Belgrade, 2004)
Benzylation of N-(4-chlorophenyl)-2-phenylacetamidewith benzyl chloride in the presence of powdered potassium hydroxide under various reaction conditions was performed in order to establish the possible reaction products. ...
Combustion of Metallurgical Wastes Using Secondary Aluminum Foils
(Taylor & Francis Inc, Philadelphia, 2017)
Simulating the reactions in a complex system can lead to self-sustaining and energy efficient treatment of wastes in recycling promoting manner. In this contribution, the synergic combination of electric arc furnace dust ...
Method for determining refractory specimen heat resistance
(Springer, New York, 2008)
The most important properties governing the operation of refractories are refractoriness, service temperature and heat resistance. The heat resistance of specimens based on Al2O3 is determined by a standard laboratory ...
Sintering behaviour of nanosized HAP powder
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
The influences of temperature and time on sintering behaviour of nanosized HAP powder were investigate in this paper. The calcium hydroxyapatite powder, with the average crystallite size of 34 +/- 1 nm, was uniaxially ...

(Association of Chemical Engineers of Serbia, 2009)
Silver(I) itaconic acid-based hydrogel complexes were synthesized and characterized in order to examine the potential use of these systems; FTIR, AFM, in vitro fluid-uptake, metal sorption and antibacterial activity assay ...
Release and diffusion studies of hydrogels based on itaconic acid
(8th Conference of the Yugoslav Materials Research Society, 2007)
Controlled release studies of drugs (theophylline (TH), fenethylline hydrochloride (FE) and gentamicin sulphate (GS)) from pH sensitive poly(2-hydroxyethyl methacrylate/itaconic acid) (P(HEMA/IA)) hydrogels obtained by ...
Removal of metal cations from wastewater using recycled wool-based non-woven material / Uklanjanje katjona metala iz otpadne vode netkanim materijalom na bazi vune kao sekundarne sirovine
(Serbian Chemical Society, Belgrade, 2007)
In this study, the effect of low-temperature air plasma, biopolymer chitosan and hydrogen peroxide treatment of recycled wool-based non-woven material on metal cation uptake was investigated. Recycled wool-based material ...
Formation of oxygen complexes in controlled atmosphere at surface of doped glassy carbon
(Indian Acad Sciences, Bangalore, 2006)
The effects of boron and phosphorus incorporation in phenolic resin precursor to the oxidation resistance of glassy carbon have been studied. In order to reveal the nature and composition of the oxygen complexes formed at ...
