Mathematical modeling and simulation of gel drying with supercritical carbon dioxide / Matematičko modelovanje i simulacija sušenja gela sa natkritičnim ugljen-dioksidom
(Serbian Chemical Society, Belgrade, 2005)
Mathematical models of alumina/silica gel supercritical drying with carbon dioxide were studied using supercritical drying experimental data. An alumina/silica gel with zinc chloride was synthesized and dried with ...
The devitrification of PbO-B2O3-ZnO glass doped with Li2O / Rastakljivanje PbO-B2O3-ZnO stakla sa dodatkom Li2O
(Serbian Chemical Society, Belgrade, 2000)
In this paper the effect of the addition of Li2O on the crystallization behavior of PbO-B2O3-ZnO glass was investigated by the differential thermal analysis (DTA) and X-ray powder diffraction (XRPD) methods. The crystallization ...
Local heat transfer coefficients during the evaporation of 1,1,1,2-tetrafluoroethane (R-134a) in a plate heat exchanger / Lokalni koeficijenti prelaza toplote pri isparavanju 1,1,1,2-tetrafluoretana (R-134a) u pločastom razmenjivaču toplote
(Serbian Chemical Society, Belgrade, 2009)
The evaporation heat transfer coefficient of the refrigerant R-134a in a vertical plate heat exchanger was investigated experimentally. The area of the plate was divided into several segments along the vertical axis. For ...
Study of the structure of phenol-formaldehyde novolac resins by NMR spectroscopy and gel-permeation chromatography
(Serbian Chemical Society, Belgrade, 1999)
C-13-NMR spectroscopy and gel-permeation chromatography studies were carried out on different samples of typical commercial phenol-formaldehyde novolac resins. Six random novolac resins (NLO 1-6), with decreasing ratios ...
Electrochemical oxidation of methanol on Pt/(RuxSn1-x)O2 nanocatalyst / Elektrohemijska oksidacija metanola na katalizatoru Pt/(RuxSn1-x)O2
(Serbian Chemical Society, Belgrade, 2013)
Ru-doped SnO2 powder, (RuxSn1-x)O2, with a Sn:Ru atomic ratio of 9:1 was synthesized and used as a support for Pt nanoparticles (30 mass % loading). The (RuxSn1-x)O2 support and the Pt/(RuxSn1-x)O2 catalyst were characterized ...
Influence of different carbon monolith preparation parameters on pesticide adsorption / Uticaj parametara dobijanja karbon monolita na adsorpciju pesticida
(Serbian Chemical Society, Belgrade, 2013)
The capacity of carbon monolith for pesticide removal from water, and the mechanism of pesticide interaction with the carbon surface were examined. Different carbon monolith samples were obtained by varying the carbonization ...
A solidification/stabilization process for wastewater treatment sludge from a primary copper smelter / Proces solidifikacije/stabilizacije za tretman otpadnih voda mulja iz primarne topionice bakra
(Serbian Chemical Society, Belgrade, 2013)
Wastewater treatment sludge from a primary copper smelter is characterized as hazardous waste that requires treatment prior to disposal due to its significant contents of heavy metals and arsenic. The aim of the presented ...
A mixture of dicyclohexylamine and oleylamine as a corrosion inhibitor for mild steel in NaCl solution saturated with CO2 under both continual immersion and top of the line corrosion / Smeša dicikloheksilamina i oleilamina kao inhibitor korozije niskougljeničnog čelika u rastvoru NaCl zasićenom sa CO2
(Serbian Chemical Society, Belgrade, 2012)
This paper presents a comprehensive method to evaluate a mixture of dicyclohexylamine and oleylamine (DCHA+OA) as a corrosion inhibitor for mild steel in a CO2 environment in the liquid and vapor phase. The volatile ...
