Transformations of 2-alkylidene-4-oxothiazolidine vinyl bromides initiated by bromophilic attack of neutral and anionic nucleophiles
(Oxford : Pergamon-Elsevier Science Ltd, 2010)
Vinyl bromides derived from 2-alkylidene-4-oxothiazolidines represent a class of vinyl halides, which readily undergo a bromophilic attack by a range of nucleophiles. With Ph(3)P, AcS(-), CN(-), I(-), F(-), Ac(2)CH(-) and ...
Modeling and optimization process parameters of acid activation of bentonite by response surface methodology
(Elsevier, 2010)
The effect of acid activation on the textural properties of a bentonite from Serbia was investigated using response surface methodology. The influence of activation parameters (temperature, time, acid normality, solid-to-liquid ...
Effect of parameters of square-wave pulsating current on copper electrodeposition in the hydrogen co-deposition range
(Elsevier Science Inc, New York, 2010)
Copper electrodeposition processes in the hydrogen co-deposition range by the pulsating current (PC) regime were examined by the determination of the average current efficiency of hydrogen evolution and by the scanning ...
Synthesis, characterization and biological activities of N-heteroaromatic hydrazones and their complexes with Pd(II), Pt(II) and Cd(II)
(Springer, Dordrecht, 2010)
Condensation derivatives of ethyl hydrazinoacetate with 2-formylpyridine and quinoline-2-carboxaldehyde were synthesized. Pd(II), Pt(II) and Cd(II) complexes with the 2-formylpyridine derivative and a Cd(II) complex with ...
Thermal diffusivity of single crystal Bi0.9Sb0.1
(International Institute for the Science of Sintering, Beograd, 2010)
A single crystal Bi0.9Sb0.1 ingot was synthesized using the Bridgman technique. Thermal diffusivity and electronic transport properties of single crystal cleaved plates (00l) were determined from PA photoacoustic phase and ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Elsevier, 2010)
The concept of higher-order frequency response functions(FRFs), which is based on Volterra series representation of nonlinear systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
Water-soluble main ions in precipitation over the southeastern Adriatic region: chemical composition and long-range transport
(Springer Heidelberg, Heidelberg, 2010)
Precipitation samples collected from 1995 to 2000 at meteorological station in the eastern outskirts of Herceg Novi (Montenegro) were analysed on Na(+), K(+), Mg(2+), Ca(2+), Cl(-), SO(4) (2-), NO(3) (-) and NH(4) (+). ...
