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 ...
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 ...
The rheological properties of wheat dough containing zeolite residue
(Chemical Industry & Chemical Engineering Quarterly, 2020)
The use of natural zeolite - clinoptilolite, to protect wheat grain from storage insects within environmentally-friendly storage techniques can lead to the presence of small amounts of zeolite residues in flour. This study ...
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 ...
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 ...
The effect of false-twist texturing parameters on the structure and crimp properties of polyester yarn
(Savez hemijskih inženjera, Beograd, 2017)
In this paper, the effect of false-twist texturing parameters (texturing speed, heater temperature, draw ratio and disc-to-yarn speed ratio (D/Y ratio)) on the structure and crimp properties of polyester yarn has been ...
Substituent effect on IR, 1H- and 13C-NMR spectral data in N-substituted phenyl)-2-cyanoacetamides: A correlation study / Uticaj supstituenata na IR, 1H- i 13C-NMR spektralne podatke N-(supstituisanih fenil)-2-cijanoacetamida - korelaciona analiza
(Association of the Chemical Engineers of Serbia, 2013)
Linear free energy relationships (LFER) were applied to the IR, 1H- and 13C- -NMR spectral data of N-(substituted phenyl)-2-cyanoacetamides. A variety of substituents were employed for phenyl substitution and fairly good ...
The effects of solvents and structure on the electronic absorption spectra of the isomeric pyridine carboxylic acid N-oxides / Uticaj rastvarača i strukture na elektronske absorpcione spektre izomernih piridin-karboksilnih kiselina N-oksida
