The morphology of cavitation damage of heat-treated medium carbon steel / Morfologija kavitacionog oštećenja srednje-ugljeničnog čelika u poboljšanom stanju
(Serbian Chemical Society, Belgrade, 2006)
In this paper the morphology of the cavitation damage to heat-treated medium carbon steel was analyzed. The experiments were conducted using a modified vibratory cavitation test set up. The erosion rates were measured by ...
Electrochemical deposition and characterization of zinc-nickel alloys deposited by direct and reverse current / Elektrohemijsko taloženje i karakterizacija legura cink-nikal dobijenih konstantnom i reversnom strujom
(Serbian Chemical Society, Belgrade, 2005)
Zn-Ni alloys electrochemically deposited on steel under various deposition conditions were investigated. The alloys were deposited on a rotating disc electrode and on a steel panel from chloride solutions by direct and ...
Inverse gas chromatrography of chromia. Part II. Finite surface coverage / Inverzna gasna hromatografija na hrom(III)-oksidu. Deo II
(Serbian Chemical Society, Belgrade, 2002)
The interactions of n-hexane, benzene, chloroform, and tetrahydrofuran with dried (amorphous) chromia (I) and chromia heated at 1073 K (crystalline) (II), both obtained from a colloidal dispersion, and a commercially ...
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 ...
Fluid dynamic studies of a three-phase fluidized bed
(Serbian Chemical Society, Belgrade, 1996)
Three phase flow and mixing in the liquid phase were studied for a draft tube fluidized bed (DTFB) operating in a circulating regime. The DTFB was considered as a system consisting of five interconnected compartiments: the ...
Electrochemical oxidation of carbon monoxide: From platinum single crystals to low temperature fuel cells catalysts - Part II: Electrooxidation of H2, CO and H2/CO mixtures on well characterized PtMo alloy / Elektrohemijska oksidacija ugljen-monoksida - od monokristala platine do katalizatora za niskotemperaturne gorivne galvanske spregove - II deo: Elektrohemijska oksidacija H2, CO I H2/CO smešama okarakterisanim PtMo legurama
(Serbian Chemical Society, Belgrade, 2003)
The oxidation of hydrogen and hydrogen–carbon monoxide mixture has been investigated on well-characterized metallurgically prepared platinum–molybdenum (PtMo) alloys. It was concluded that the optimum surface concentration ...
