Remediation of environment contaminated by lead using synthetic and natural apatites / Stabilizacija zagađenja olovom korišćenjem sintetičkih i prirodnih apatita
(Association of the Chemical Engineers of Serbia, 2001)
Lead contamination is an environmental concern due to its effect on human health. One of the ways of remediating lead contamination is the in situ stabilization of this heavy metal. This can be achieved by converting ...
A study of the catalytic role of a gold electrode in the electrochemical activation of four macrolide antibiotics in sodium bicarbonate solution / Ispitivanje katalitičke uloge elektrode od zlata u elektrohemijskoj aktivaciji četiri makrolidna antibiotika u natrijum-bikarbonatnom elektrolitu
(Association of the Chemical Engineers of Serbia, 2010)
Using the cyclic voltammetry, it has been shown that hydrogen evolution at a gold electrode is necessary in the electrochemical activation of azithromycin dihydrate and erythromycin A. After four hours of the potential ...
EI/MS/MS spectra of N-monosubstituted cyanoacetamides / EI/MS/MS spektri N-monosupstituisanih cijanoacetamida
(Association of the Chemical Engineers of Serbia, 2010)
The electron-ionization induced mass spectra of twenty six N-monosubstituted cyanoacetamides were recorded and their fragmentation patterns were studied. The effect of N-alkyl and N-aryl substituents to the fragmentation ...
The batch fractionation of Juniperus communis L. essential oil: Experimental study, mathematical simulation and process economy / Frakciona destilacija etarskog ulja Juniperus communis L. - laboratorijska ispitivanja, matematička simulacija i ekonomika procesa
(Association of the Chemical Engineers of Serbia, 2010)
The separation in a batch vacuum column of the essential oil of common juniper berries (Juniperus communis L., from the southern part of Serbia) was analyzed. The main goal of the analyzed separation process was to isolate ...
Oxidative stabilization of sunflower oil by antioxidant fractions from selected Lamiaceae herbs / Oksidativna stabilizacija suncokretovog ulja sa antioksidativnim frakcijama iz odabranih biljaka familije Lamiaceae
(Association of the Chemical Engineers of Serbia, 2010)
This study reports the effect of antioxidant fractions from rosemary (Rosmarinus officinalis), sage (Salvia officinalis), thyme (Thymus vulgaris) and hyssop (Hyssop officinalis) on the oxidative stability of sunflower oil ...
Drying of immobilized yeast cells in a spouted bed dryer with a moving draft tube / Sušenje imobilisanih ćelija pivskog kvasca u sušioniku sa fontanskim slojem i pokretnom centralnom cevi
(Association of the Chemical Engineers of Serbia, 2010)
Brewery yeast cells immobilized in Ca-alginate were dried in a laboratory scale spouted bed with a draft tube. The experiment was conducted under variable temperatures and air flow rates. The temperature and air velocity ...
A new ecologically friendly process for the synthesis of selective flotation reagents
(Association of the Chemical Engineers of Serbia, 2009)
A new ecologically friendly synthesis of N-alkyl-O-ethylthioncarbamates from ethyl dixanthogenates, waste material from the xanthate production plant, and monoalkylamines has been performed in this work. Structure determination ...
In vitro evaluation of the controlled release of antibiotics from liposomes / In vitro ispitivanje kontrolisanog otpuštanja antibiotika iz liposoma
(Association of the Chemical Engineers of Serbia, 2003)
Results of this study have shown significantly prolonged release of selected antibiotic from liposome dispersion as compared to free antibiotic solution of the same initial concentration. Two models of non-steady one-dimensional ...
The immobilization of lipase on Sepabeads: Coupling, characterization and application in geranyl butyrate synthesis in a low aqueous system
(Association of the Chemical Engineers of Serbia, 2008)
Lipase from Candida rugosa immobilized on Sepabeads EC-EP was shown to catalyze the esterification of geraniol with butyric acid in a predominantly organic system. The immobilization procedure was adjusted to optimize the ...
Chromatophore based cytosensor: Responses to various biologically active agents / Citosenzor na bazi hromatofora - ispitivanje odgovora različitih biološki aktivnih agenasa
(Association of the Chemical Engineers of Serbia, 2006)
The design, operation and performances of a cytosensor based on immobilized living chromatophores isolated from Betta splendens Siamese fighting fish are presented in this paper. Development of the cell immobilization ...
