Silver in copper intermediates of lead refinery 'Trepča' / Srebro u bakarnim međuproduktima rafinerije olova 'Trepča'
(Savez inženjera i tehničara Srbije, Beograd, 2007)
Lead ores and concentrates always have significant content of silver and copper. During the process of lead bullion refining these two metals are separated and concentrated into the intermediates which have special ...
The influence of high and low temperatures on the impact properties of glass-epoxy composites / Uticaj visokih i niskih temperatura na udarna svojstva stakleno−epoksidnih kompozita
(Serbian Chemical Society, Belgrade, 2007)
The aim of this paper is to present the influence of high and low temperatures on the impact properties glass-epoxy composites. The impact strength an is presented for four different glass-epoxy composite structures at ...
The effect of agitation intensity on alkali-catalyzed methanolysis of sunflower oil
(Elsevier, 2007)
The sunflower oil methanolysis was studied in a stirred reactor at different agitation speeds. The measurements of drop size, drop size distribution and the conversion degree demonstrate the effects of the agitation speed ...
High activity of Pt4Mo alloy for the electrochemical oxidation of formic acid
(Amer Chemical Soc, Washington, 2007)
Surface processes on Pt4Mo alloy well-defined by X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were studied in acid solution by cyclic voltammetry. It was established that Mo in the alloy is much more ...
Mixtures of methanol and 2-propanol as a potential fuel for direct alcohol fuel cells / Smeša metanola i 2-propanola kao potencijalno gorivo u gorivim spregovima sa alkoholom
(Serbian Chemical Society, Belgrade, 2007)
The electrochemical oxidation of methanol, 2-propanol, and their mixtures was investigated on a Pt/C thin film electrode in acid solution. It was confirmed that the oxidation of 2-propanol commences at less positive ...
Influence of an antimicrobial treatment on the strength properties of polyamide/elastane weft-knitted fabric
(Wiley, Hoboken, 2007)
Polyamide/elastane weft-knitted fabric, as a suitable compression material, was treated with gentamicin sulfate and a natural antimicrobial preparation of the autochthonous essential oil of Picea abies. The antimicrobial ...
Analysis of the properties of a Cu-Al2-O3 sintered system based on ultra fine and nanocomposite powders
(International Institute for the Science of Sintering, Beograd, 2007)
In this paper synthesis of a composite based on Cu-Al2O3 by a thermo-chemical method is shown along with a comparative analysis of the properties of the obtained nanocomposite sintered samples, which are characterized by ...
Numerical method for the prediction of bending properties of glass-epoxy composites / Primena numeričkog modela za predviđanje savojnih svojstava staklo-epoksi kompozitnog materijala
(Faculty of Technology, Novi Sad, 2007)
Mechanical properties of composite materials are conditioned by their structure and depend on the characteristics of structural components. In this paper is presented a numerical model by which the bending properties can ...
Significance and application of geothermal waters of Jošanica spa / Značaj i primena geotermalnih voda Jošaničke Banje
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd i Društvo termičara Srbije, Beograd, 2007)
Geothermal energy takes important place in application of alternative energy sources. Geothermal energy is promising energy source, ecological safe because it belongs to renewable energy resources. Potential of geothermal ...
