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 ...
Gas-solid and gas-liquid mass transfer: Effect of turbulent Schmidt number
(Association of the Chemical Engineers of Serbia, 2007)
The scope of this paper is to explain effect of eddy viscosity and turbulent Schmidt number on mass transfer rate. New, theoretically based correlation for gas-liquid mass transfer coefficients are proposed.
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 ...
Immobilization of fish chromatophores for use as a micro-biosensor for biological toxins / Imobilizacija hromatofora riba radi korišćenja kao biosenzor za biološke toksine
(Association of the Chemical Engineers of Serbia, 2003)
Chromatophores isolated from the Siamese fighting fish, Betta splendens, represent a class of living cells that provide a vivid color response to microbial pathogens and environmental toxins. The selection of the most ...
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 ...
Optimization of the electrostatic droplet generation process for controlled microbead production: Single nozzle system / Optimizacija elektrostatičkog generisanja čestica u cilju kontrolisanja njihovih mikronskih veličina - sistem sa jednom mlaznicom
(Association of the Chemical Engineers of Serbia, 2006)
The aim of this study was to optimize the electrostatic extrusion process for producing small, spherical and uniform microbeads with different fluid viscosities by varying the operating parameters in very wide ranges. ...
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 ...
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 ...
Cleaner metallurgical industry in Serbia: A road to the sustainable development
(Association of the Chemical Engineers of Serbia, 2009)
Since the sustainable development has been a global and fundamental objective, a metallurgical industrial sector faces some of the most difficult sustainability challenges of any industrial sector. On the other hand, the ...
