Mass transfer between a fluid and an immersed object in liquid-solid packed and fluidized beds / Prenos mase fluid-uronjeni objekat u pakovanim i fluidizovanim slojevima tečnost-čestice
(Serbian Chemical Society, Belgrade, 2005)
The mass transfer coefficient between fluid and an immersed sphere in liquid packed and fluidized beds of inert spherical particles have been studied experimentally using a column 40 mm in diameter. The mass transfer data ...
Study of gold-platinum and platinum-gold surface modification and its influence on hydrogen evolution and oxygen reduction / Površinska modifikacija platine zlatom i zlata platinom i njen uticaj na reakcije izdvajanja vodonika i redukcije kiseonika
(Serbian Chemical Society, Belgrade, 2005)
Surface modification of the electrodes was conducted from sulfuric acid solutions containing the corresponding metal-chloride complexes using cyclic voltammeter. Comparing the charges of the hydrogen underpotential deposition ...
Exchange between the stagnant and flowing zone in gas-flowing solids-fixed bed contactors / Razmena čestica između pokretne i nepokretne zone u kontaktorima gas-pokretna čvrsta faza-pakovan sloj
(Serbian Chemical Society, Belgrade, 2005)
In countercurrent gas - flowing solids - fixed bed contactors, a fraction of the flowing solids is in motion (dynamic holdup), while the other fraction is resting on the fixed bed elements. In this study it was experimentally ...
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 ...
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 ...
NMR analysis of (1S, 1aR, 6aR)-2’, 3’, 6, 6a-tetrahydrospiro cycloprop a indene-1(1aH), 1’- 1H indene / NMR analiza (1S,1aR,6aR)-2’,3’,6,6a-tetrahidro-spiro[cikloprop[a]inden-1(1ah),1’-[ 1h]indena]
(Serbian Chemical Society, Belgrade, 2005)
The aldol condensation product of 1H-indan-1-one, (2E)-2-(2,3-dihydro-1H-in den-1-ylidene)-2,3-dihydro-1H-inden-1-one, subjected to Huang–Minlon reduction conditions was shown, via 1D and 2D NMR analysis, to be a mixture ...
Vapour-liquid equilibrium of the OPLS, optimized potentials for liquid simulations, model for binary systems of alkanes and alkanes + alcohols / Ravnoteža para-tečnost OPLS, optimizovanje potencijala za tečnu simulaciju, modela binarnih sistema alkana i alkana + alkohola
(Serbian Chemical Society, Belgrade, 2005)
The NpT - Gibbs ensemble Monte Carlo computer simulation method was applied to predict the vapour-liquid equilibrium (VLE) behavior of the binary systems ethane + pentane at 277.55 K and 310.95 K, ethane + hexane at 298.15 ...
Preparation and characterization of two types of covalently immobilized amyloglucosidase / Dobijanje i karakterizacija dva tipa imobilizovane amiloglukozidaze
(Serbian Chemical Soc, Belgrade, 2005)
Amyloglucosidase from A. niger was covalently immobilized onto poly(GMA-co-EGDMA) by the glutaraldehyde and periodate method. The immobilization of amyloglucosidase after periodate oxidation gave a preparate with the highest ...
AFM studies of DNA structures extracted from adriamycin treated and non-treated Ehrlich tumor cells
(Srpsko hemijsko društvo, Beograd, 2005)
