Fabrication and characterization of HA-ZrO2-MWCNT ceramic composites
(Sage Publications Ltd, London, 2010)
In this article, a new kind of hydroxyapatite-zirconia-carbon nanotube (HA-ZrO2-MWCNT) ceramic composites was fabricated to enhance the mechanical properties of a hydroxyapatite (HA) ceramic for satisfying various requirements ...
Environmental pollution by heavy metals and biodiversity monitoring of places Kosovska Mitrovica and Zvečan / Zagađenje životne sredine teškim metalima i monitoring biodiverziteta gradova Kosovske Mitrovice i Zvečana
(Naučno-stručno društvo za zaštitu životne sredine Srbije - Ecologica, Beograd, 2010)
Research takes place in areas of Kosovska Mitrovica and Zvecan with the aim to determine content of following heavy metals: Pb, Cd, Cr, Hg, Zn and also pH values in surface water of Ibar river, underground waters (wells) ...
Removal of organochlorine pesticides from water using virgin and regenerated granular activated carbon / Uklanjanje pesticida iz vode na granulisanom aktivnom uglju
(Serbian Chemical Society, Belgrade, 2010)
Public water systems use granular activated carbon in order to eliminate pesticides. After saturation, the used activated carbon is regenerated and reused in order to reduce the costs of water production and minimize waste. ...
Simplification of the synthesis of the reversible addition-fragmentation chain transfer agent 2-(2-cyanopropyl)-dithiobenzoate / Pojednostavljenje postupka sinteze raft agensa 2-(2-cijanopropil)-ditiobenzoata
(Serbian Chemical Society, Belgrade, 2010)
The general literature procedure for the preparation of the reversible addition-fragmentation chain transfer (RAFT) agent 2-(2-cyanopropyl)-dithiobenzoate (CPDB) was modified by omitting the recrystallisation of the ...
Deformation mechanisms in ti3al-nb alloy at elevated temperatures
(Institute of Metals and Technology, 2010)
Ti3Al-11Nb-1V (x/%) was made in a vacuum arc furnace. Hot-rolling was conducted at 1050 degrees C in a two-phase field of the alloy. Strain-rate jump tests were performed at T = 800-1100 degrees C and strain rates of 10(-6) ...
Modeling of strength degradation during water quench test of low cement high alumina castable
(University of Chemistry and Technology, Prague, 2010)
Low cement high alumina castable was synthesized, cured, and then sintered at 1100 degrees C for 3 hours. Water quench test was used as an experimental method for thermal stability testing. Image analysis program was applied ...

The paper elaborates determination of characteristic values in the discharging process of non-hermetic nickel-cadmium galvanic battery with nominal voltage Un = 60 V and nominal capacity qn = C5 = 190 A h and its dependence ...
Comparative analysis of fecal DNA extraction methods with phylogenetic microarray: Effective recovery of bacterial and archaeal DNA using mechanical cell lysis
(Elsevier Science Bv, Amsterdam, 2010)
Several different protocols are used for fecal DNA extraction, which is an integral step in all phylogenetic and metagenomic approaches to characterize the highly diverse intestinal ecosystem. We compared four widely used ...
Rearrangement of erythrocyte band 3 molecules and reversible formation of osmotic holes under hypotonic conditions
(Springer, New York, 2010)
The complex phenomenon of rearrangement of band 3 molecules after erythrocyte swelling under hypotonic condition is considered. The rearrangement includes the increase of the mobile fraction and clustering of band 3. The ...
