The influence of titanium and cerium on microstructure and properties of Fe-C-Cr-Nb alloys / Uticaj titana i cerijuma na mikrostrukturu i svojstva Fe-C-Cr-Nb legura
(Savez inženjera metalurgije Srbije, Beograd, 2005)
In this paper, the influence of titanium and cerium on the microstructure and properties of Fe-C-Cr-Nb alloys are examined, in both as-cast and heat treated state. These elements affect the crystallisation process of ...
Thermomechanical processing of micro alloyed steels in Sartid A.D.: Part III - comparison of of Tnr temperatures determined on laboratory and industrial scale / Termomehanička prerada mikrolegiranih čelika koncerna Sartid: III deo - poređenje Tnr temperatura određenih u laboratorijskim i industrijskim uslovima
(Savez inženjera metalurgije Srbije, Beograd, 2002)
The aim of this work was to compare the Tnr temperatures of microalloyed steels estimated on laboratory (Tnr**l) and industrial scale (Tnr**l). Laboratory and industrial scale are related to testing on high temperature ...
The retention behavior of some uracil derivatives in normal and reversed-phase chromatography. Lipophilicity of the compounds
(Research Inst Medicinal Plants, Budakalasz, 2005)
The chromatographic behavior of newly synthesized uracil derivatives has been studied by normal and reversed-phase thin-layer chromatography. Benzene-methanol, benzene-acetonitrile, and benzene-isopropanol were used as ...
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 ...
Development of a microbiosensor based on fish Chromatophores immobilized on ferromagnetic gelatin beads
(University of Zagreb, 2005)
Development of a microbiosensor based on immobilized living chromatophores of Siamese fighting fish, Betta splendens, for the detection of microbial and environmental toxins is described in this paper. Chromatophores were ...
Microwaves in organic chemistry and organic chemical technology / Primena mikrotalasne tehnike u organskoj hemiji i organskoj hemijskoj tehnologiji
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2005)
The usual way of applying heat to a chemical reaction is the use of a Bunsen burner, an oil or some other type of bath, or an electric heater. In inorganic chemistry, microwave technology has been used since the late 1970s, ...
Dynamical mechanical analysis of photocrosslinked hyperbranched urethane acrylates
(Srpsko hemijsko društvo, Beograd, 2004)
A series of acrylate functionalized samples based on hyperbranched hydroxy-terminated polyesters with different molecular weights and different degrees of acrylation were synthesized. The obtained urethane acrylates were ...
A novel approach to determination of carbonyl groups in DMAc/LiCl-insoluble pulps by fluorescence labeling
(Springer, Dordrecht, 2006)
The CCOA method for profiling of carbonyl groups by fluorescence labeling has meanwhile become an established procedure for dissolving pulps and rag papers. High molecular weight pulps, such as certain paper pulps, could ...
Excess molar volume of acetonitrile + alcohol systems at 298. 15 K. - Part II: Correlation by cubic equation of state / Dopunska molarna zapremina sistema acetonitril + alkohol na 298.15 K. - II deo - korelisanje pomoću kubne jednačine stanja
(Serbian Chemical Society, Belgrade, 2003)
The excess molar volume VE of the binary liquid systems acetonitrile methanol and acetonitrile + ethanol, experimentally determined in the previous part, were correlated by the PRSV CEOS coupled with the vdW and TCBT mixing ...
Low energy impact damage detection in laminar termoplastic composite materials by means of embedded optical fibers
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The possibility of applying optical fibers as sensors for investigation of real time low energy impact damage in laminar thermoplastic composite materials has been studied. For that purpose intensity based optical fibers ...
