Preparation and studies on immobilized α-glucosidase from baker’s yeast Saccharomyces cerevisiae / Dobijanje i proučavanje imobilizacije α-glukozidaze iz pekarskog kvasca Saccharomyces cerevisiae
(Serbian Chemical Society, Belgrade, 2007)
α-Glucosidase from S. cerevisiae was covalently immobilized onto Sepabeads EC-EA by the glutaraldehyde method. An analysis of the variables controlling the immobilization process is first presented and it is shown that the ...
Electrodeposition and characterization of Fe-Mo alloys as cathodes for hydrogen evolution in the process of chlorate production / Elektrohemijsko taloženje i karakterizacija Fe-Mo legura kao katoda za reakciju izdvajanja vodonika u industrijskom procesu proizvodnje hlorata
(Serbian Chemical Society, Belgrade, 2005)
Fe–Mo alloys were electrodeposited from a pyrophosphate bath using a single diode rectified AC current. Their composition and morphology were investigated by SEM, optical microscopy and EDS, in order to determine the ...
Cross-section analysis of the morphology of electrodeposited copper obtained in the hydrogen co-deposition range / Morfologija poprečnog preseka prevlaka bakra dobijenih elektrohemijskim taloženjem u oblasti ko-depozicije vodonika
(Serbian Chemical Society, 2009)
Cross-section analysis of copper deposits electrodeposited in the hydrogen co-deposition range at a constant overpotential and in a pulsating overpotential (PO) regime was performed. It was shown that a complete structural ...
Electrodeposition and characterization of Fe-Mo alloys as cathodes for hydrogen evolution in the process of chlorate production (vol 70, pg 879, 2005)
(Srpsko hemijsko društvo, Beograd, 2005)
Excess molar volume of acetonitrile + alcohol systems at 298. 15 K. - Part II: Correlation by cubic equation of state / Dopunska molarna zapremina sistema acetonitril + alkohol na 298.15 K. - II deo - korelisanje pomoću kubne jednačine stanja
(Serbian Chemical Society, Belgrade, 2003)
The excess molar volume VE of the binary liquid systems acetonitrile methanol and acetonitrile + ethanol, experimentally determined in the previous part, were correlated by the PRSV CEOS coupled with the vdW and TCBT mixing ...
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 ...
Densification and crystallization behaviour of colloidal cordierite-type gels / Denzifikacija i kristalizacija koloidnih gelova kordijeritnog sastava
(Serbian Chemical Society, Belgrade, 2001)
Three cordierite-type gels were prepared from an aqueous solution of Mg(NO3)2, a boehmite sol and silica sols of very small particle sizes. The effect of varying the silica particle size on the crystallization and densification ...
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 ...
Artificial neural network prediction of quantitative structure - retention relationships of polycyclic aromatic hydocarbons in gas chromatography
(Srpsko hemijsko društvo, Beograd, 2005)
A feed-forward artificial neural network (ANN) model was used to link molecular structures (boiling points, connectivity indices and molecular weights) and retention indices of polycyclic aromatic hydrocarbons (PAHs) in ...
The influence of a cryoprotective medium containing glycerol on the lyophilization of lactic acid bacteria / Uticaj krioprotektivnog medijuma sa glicerolom na liofilizaciju bakterija mlečne kiseline
(Serbian Chemical Society, 2001)
The aims of lyophilization (freeze-drying) of lactic acid bacteria are to preserve pure cultures or to prepare starters for the dairy industry. In both cases, the choice of the cryoprotectant is very important. In this ...
