Utilization of baker's yeast (Saccharomyces cerevisiae) for the production of yeast extract: Effects of different enzymatic treatments on solid, protein and carbohydrate recovery / Primena pekarskog kvasca (Saccharomyces cerevisiae) za dobijanje kvaščevih ekstrakata - uticaj različitih parametara enzimske hidrolize na sadržaj suve materije, proteina i ugljenih hidrata
(Serbian Chemical Society, Belgrade, 2007)
Yeast extract (YE) was produced from commercial pressed baker's yeast (active and inactivated) using two enzymes: papain and lyticase. The effects of enzyme concentration and hydrolysis time on the recovery of solid, protein ...
Kinetics and mechanism of As2S2 oxidation / Кинетика и механизам процеса оскидације једињења Аs2S2
(Serbian Chemical Society, 2005)
The kinetics of realgar (As2S2) oxidation was studied under isothermal and non-isothermal conditions. The obtained values of the activation energy indicate that the process occurs in the kinetic domain with the realgar ...
Investigation of different extraction procedures for the determination of major and trace elements in coal by ICP-AES and ion chromatography
(Srpsko hemijsko društvo, Beograd, 2016)
This paper presents the extraction of major and trace elements from a coal sample, in deionized water, by using three different extraction techniques. Rotary mixing and ultrasonic extraction were examined for different ...
Synthesis, structure and properties of thermoplastic poly(ester-siloxane) elastomers
(Serbian Chemical Society, 2006)
Two series of thermoplastic poly(ester-siloxane) elastomers (TPES), with hard segments based on poly(butylene terephthalate) (PBT) and soft segments based on poly(dimethylsiloxane) (PDMS), were synthesized by high-temperature, ...
PMMA-Y2O3 (Eu3+) nanocomposites: Optical and mechanical properties / Nanokompozit PMMA-Y2O3 (Eu3+) - optička i mehanička svojstva
(Serbian Chemical Society, Belgrade, 2011)
The results of a study related to the processing and characterization of poly(methyl methacrylate) (PMMA)-Y2O3 (Eu3+) nanocomposites are presented herein. The nanocomposite samples were prepared using a laboratory mixing ...
Electrochemical oxidation of methanol on Pt3Co bulk alloy / Elektrohemijska oksidacija metanola na leguri Pt3Co
(Serbian Chemical Society, Belgrade, 2003)
The electrochemical oxidation of methanol was investigated on a Pt3Co bulk alloy in acid solutions. Kinetic parameters such as transfer coefficient reaction orders with respect to methanol and H+ ions and energy of activation ...
Accumulation of trace metals in marine organisms of the southeastern Adriatic coast, Montenegro
(Serbian Chemical Society, 2012)
The concentration and accumulation of trace metals (Co, Ni, As, Cd, Pb and Hg) were measured in seawater, sediments and marine organisms on the coastline of Montenegro. The obtained results of trace metals in sea grass and ...
Synthesis and characterization of mu-hydroxido- and mu-polycarboxylato-bridged iron(III) complexes with 2,2 '-bipyridine / Синтеза и карактеризација гвожђе(III)-комплекса са μ-хидроксидо и μ-поликарбоксилато мостовима и 2,2′-бипиридином
(Srpsko hemijsko društvo, 2014)
Four novel polymeric iron(III) complexes with 2,2'-bipyridine (bipy) and different aromatic polycarboxylato ligands as anions of phthalic (pht), isophthalic (ipht), terephthalic (tpht) and pyromellitic (pyr) acid were ...
Drying of suspension and pastes in fluidized bed of inert particles / Sušenje suspenzija i pasta u fluidizovanom sloju inertnog materijala
(Serbian Chemical Society, 2000)
A fluid bed dryer with inert particles was used for the drying of suspensions and pastes. The effects of the operating conditions on the dryer throughput and on the product quality were investigated. Experiments were ...
