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 ...
Influence of current and temperature on discharge characteristics of electrochemical nickel-cadmium system / Uticaj struje i temperature na karakteristike pražnjenja elektrohemijskog nikal-kadmijum sistema
(Association of Chemical Engineers of Serbia, 2010)
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 ...
Phase transition at subcritical and supercritical conditions of triglycerides methanolysis
(Elsevier, Amsterdam, 2010)
The analysis of phase equilibrium between methanol and glycerides during methyl esters of fatty acids (FAME or biodiesel) synthesis at high pressure and temperature is very important for describing the kinetic and process ...
Synthesis, structure and solvatochromic properties of 3-cyano-4,6-diphenyl-5-(3- and 4-substituted phenylazo)-2-pyridones / Sinteza, struktura i solvatohromna svojstva 3-cijano-4,6-difenil-5-(3- i 4-supstituisanih fenilazo)-2-piridona
(Serbian Chemical Society, Belgrade, 2010)
A series of some new pyridone arylazo dyes was synthesized from the corresponding diazonium salts and 3-cyano-4,6-diphenyl-2-pyridone using the classical reaction for the synthesis of the azo compounds. The structures of ...
Swelling of plant material in supercritical carbon dioxide
(Elsevier, Amsterdam, 2010)
Swelling of plant material belonging to several plant families and the influence of swelling on supercritical fluid extraction process were investigated in this study. While swelling of Lamiaceae family species as well as ...
Electrochemical characterization of polyaniline electrode in ammonium citrate containing electrolyte
(Elsevier Science Sa, Lausanne, 2011)
