The influence of zinc surface pretreatment on the adhesion of epoxy coating electrodeposited on hot-dip galvanized steel
(Elsevier Science Sa, Lausanne, 2007)
The adhesion and electrochemical properties of epoxy coatings electrodeposited on hot-dip galvanized steel with and without passive films were investigated during exposure to 3% NaCl. The passive films were formed in hot ...
Deformation behaviour of welded stainless steel: Carbon steel sandwich sheet material / Deformaciono ponašanje zavarenog spoja sendvič lima nerđajući čelik - ugljenični čelik - nerđajući čelik
(Military Technical Institute, Belgrade, 2007)
Formability of welded austenitic stainless steel (321 type) - low carbon steel (1010 type) sandwich sheet material was tested. Gas tungsten arc welding (GTAW) and shield metal arc welding (SMAW) procedures were used. After ...
Stillage as by-product of alcoholic fermentation / Džibra - sekundarni proizvod alkoholne fermentacije
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2007)
Processes of bioethanol production from sugars, starch or cellulose produce enormous amounts of stillage (about 20 dm3 per dm3 ethanol), as a by-product. Chemically, stillage is an aqueous solution of different products ...
Preparation of heterogeneous catalyst for biodiesel synthesis
(2007 AIChE Annual Meeting, 2007)
Certain disadvantages of conventional processes of biodiesel, e.g., fatty acid methyl esters (FAME) synthesis could be avoided by applying new technologies that are based on using heterogeneous catalyst. A new type of ...
Characterization of microflora in homemade semi-hard white Zlatar cheese
(Elsevier Science Bv, Amsterdam, 2007)
The Zlatar cheese belongs to the group of traditionally homemade cheeses, which are produced from nonpasteurized cow's milk, without adding of any bacterial starter culture. Changes were followed in lactic acid bacteria ...
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 ...
Synthesis of nanosized calcium hydroxyapatite particles by the catalytic decomposition of urea with urease
(Cambridge Univ Press, New York, 2007)
Nanosized calcium hydroxyapatite particles were synthesized by the catalytic decomposition of urea with urease. The influence of the synthesis parameters, i.e., temperature and ratio of the reagents/urease concentrations, ...
Protection of probiotic microorganisms by microencapsulation
(Association of the Chemical Engineers of Serbia, 2007)
Probiotic bacteria are used in the production of fermented dairy foods, pharmaceutical products and health supplements. They play an important role in promoting and maintaining human health. In order, to produce health ...
Theoretical investigation of the adsorption of a binary mixture in a chromatographic column using the nonlinear frequency response technique
(Springer, New York, 2007)
The nonlinear frequency response of a chromatographic column for the adsorption of two dissolved components is analyzed using the concept of higher order frequency response functions (FRFs) which is based on the Volterra ...
Theoretical assessment of calcium arsenates stability: Application in the treatment of arsenic contaminated waste
(8th Conference of the Yugoslav Materials Research Society, 2007)
Several approaches for immobilization of arsenic (As) based on the transformation of its soluble forms (compounds) into highly insoluble arsenate apatite Ca5(AsO4)3 OH have been proposed. These immobilization techniques ...
