The break through moment in evolution of human community is discover of some metals. Developing mining and metallurgy in eastern Serbia was depended of developing The Bor mining and metallurgical complex (RTB Bor). The ...
Isopiestic investigation of the osmotic and activity coefficients of {yMgCl(2)+(1-y)MgSO4}(aq) and the osmotic coefficients of Na2SO4 center dot MgSO4(aq) at 298.15 K
(Springer/Plenum Publishers, New York, 2008)
Isopiestic vapor-pressure measurements were made for {yMgCl(2) + (1-y)MgSO4}(aq) solutions with MgCl2 ionic strength fractions of y = (0,0.1997,0.3989,0.5992,0.8008, and 1) at the temperature 298.15 K, using KCl(aq) as the ...
Factors influencing the removal of divalent cations by hydroxyapatite
(Elsevier, Amsterdam, 2008)
The effect of pH, contact time, initial metal concentration and presence of common competing cations, on hydroxyapatite (HAP) sorption properties towards Ph2+, Cd2+, Zn2+, and Sr2+ ions was studied and compared using a ...
The effects of hemicelluloses and lignin removal on water uptake behavior of hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
This study investigated the individual influences of hemicelluloses and lignin removal on the water uptake behavior of hemp fibers. Hemp fibers with different content of either hemicelluloses or lignin were obtained by ...
Densities and excess molar volumes of the ternary mixture 2-butanol plus chloroform plus benzene and binary mixtures 2-butanol plus chloroform, or plus benzene over the temperature range (288.15 to 313.15) K
(Amer Chemical Soc, Washington, 2008)
Densities rho and excess molar volumes V(E) of the 2-butanol + chloroform + benzene ternary mixtures and two binaries, 2-butanol + chloroform and 2-butanol + benzene, have been determined. Experimental rho measurements ...
Analysis of amphetamines illegally produced in Serbia / Analiza amfetamina ilegalno proizvedenog u Srbiji
(Serbian Chemical Society, Belgrade, 2008)
Forensic practice in the Republic of Serbia faced the illegal production of amphetamine for the first time in 2003. This paper presents the results of the chemical characterization of 32 batches of amphetamine samples from ...

The possibility of using a corona treatment (electrical discharge at atmospheric pressure) for fiber surface activation, which can facilitate the loading of silver nanoparticles (NPs) from colloids onto the polyester (PES) ...
Surface carriers' concentration dynamics caused by a small alternating applied voltage
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
One of our previous papers was devoted to threshold voltage in MOSFETs and MODFETs viewed as a problem of nonlinear dynamics. The behavior of surface carriers' concentration under D.C. (direct current) applied voltage has ...
Monitoring of chlorobenzene impact on rapid aging of pet bottles by image analysis / Praćenje uticaja hlorbenzena na ubrzano starenje poli(etilen tereftalatnih) bočica metodom analize slike
(Institut IMK "14. oktobar", Kruševac, 2008)
Poly(ethylene terephthalate) (PET) is a material widely used for various kinds of packaging, because of its superior barrier properties, low price and simple processing. Apart from aqueous products, it is being used as a ...
