Characterization of thermal shock damage in cordierite-mullite refractory materials by non-destructive methods
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Ultrasonic pulse velocity testing and image analysis were used to predict thermal stability of refractories. Two cordierite-mullite compositions used as substrates in fast firing of porcelain white ware characterized by ...
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 ...
Biodegradable polyesters based on succinic acid / Biodegradabilni poliestri na bazi ćilibarne kiseline
(Association of Chemical Engineers of Serbia, 2003)
Two series of aliphatic polyesters based on succinic acid were synthesized by copolymerization with adipic acid for the first series of saturated polyesters, and with fumaric acid for the second series. Polyesters were ...
Artificial neural network data analysis for classification of soils based on their radionuclide content
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The artificial neural network (ANN) data analysis method was used to recognize and classify soils of an unknown geographic origin. A total of 103 soil samples were differentiated into classes according to the regions in ...
Bioactive glass-apatite composite coating for titanium implant synthesized by electrophoretic deposition
(Elsevier Sci Ltd, Oxford, 2007)
Titanium and titanium alloys are widely used as materials for implants, because of their mechanical properties and nontoxic behaviour, but unfortunately, are bioinert. In order to solve this problem, the metal implant could ...
Influence of formation conditions and precursor viscosity on mean fiber diameter formed using the relating disk method
(Elsevier, Amsterdam, 2000)
Alumina ceramic fibers were produced from aluminum-hydroxidechloride based sol. Polyvinyl alcohol and surface active material were applied to adjust the rheological characteristics of the: sol. The rotating disk formation ...
Electrostatic generation of alginate microbeads loaded with brewing yeast
(Association of Chemical Engineers of Serbia, 2004)
Depozition of thin films by CVD techniques / Nanošenje tankih filmova CVD postupcima
(Savez inženjera metalurgije Srbije, Beograd, 2004)
Chemical vapor deposition - (CVD) has rapidly grown in the last twenty years and applications of this fabrication process are now key elements in many industrial products, such as semiconductors, optoelectonics, optics, ...
The processes of hard metals recycling / Postupci recikliranja otpadaka tvrdog metala
(Savez inženjera i tehničara Srbije, Beograd, 2003)
In this paper we have given review the basic properties treatments and advantages of recycling hard metal`s scrap, where should emphasize fact, that in our country and the other Balkan s countries don't carry out any hard ...
Re-refining of waste mineral insulating oil by extraction with N-methyl-2-pyrrolidone
(Elsevier Science Bv, Amsterdam, 2006)
Extraction with N-methyl-2-pyrrolidone (NMP) via the three-stage mixer-settler operation was studied as possible process for re-refining of waste mineral insulating oil. The following extraction process parameters were ...
