Polymerization of Itaconic Acid Initiated by a Potassium Persulfate/N,N-Dimethylethanolamine System
(Wiley, Hoboken, 2008)
The synthesis and characterization of poly (itaconic acid) (PIA) with a novel initiator/activator system is presented. The initiator in this system was potassium persulfate, whereas the activator was N,N-dimethylethanolamine ...
The ionic equilibrium in the CuSO4-H2SO4-H2O system and the formation of the honeycomb-like structure during copper electrodeposition / Jonska ravnoteža u sistemu CuSO4-H2SO4-H2O i formiranje strukture pčelinjeg saća elektrohemijskim taloženjem bakra
(Serbian Chemical Society, 2008)
The ionic equilibrium of the species in the CuSO4-H2SO4-H2O system was employed to systematize the conditions of copper electrodeposition leading to the formation of the honeycomb-like structure. The reason why CuSO4 ...
Structural characteristics of some ternary Ag-In-Sn alloys
(Savez inženjera metalurgije Srbije, Beograd, 2008)
The Ag-In-Sn system, as one of potential lead-free solder materials, was studied in this paper. The investigated alloys were chosen from two sections, with molar ratio of In:Sn equal to 1:4; 1:2. DTA, XRD, SEM and micro ...
Toksičnost i kinetika otpuštanja insulina iz hormonaktivnih polisaharidnih vlakana
(Univerzitet u Beogradu - Medicinski fakultet, Beograd, 2008)
In this paper an account of biocompatibility of a hormonactive fiber in the form of biologically active complex chitosan-insulin is presented. The behavior of artificial depots of insulin containing 180-330mg of insulin ...
Electrocatalytic properties and stability of titanium anodes activated by the inorganic sol-gel procedure / Titanske anode aktivirane oksidnom prevlakom dobijenom sol-gel postupkom
(Serbian Chemical Society, 2008)
The properties of activated titanium anodes, RuO2-TiO2/Ti and RuO2--TiO2-IrO2/Ti, prepared from oxide sols by the sol-gel procedure, are reviewed. RuO2 and TiO2 sols were synthesized by forced hydrolysis of the corresponding ...
Trans- and cis-resveratrol concentration in wines produced in Serbia / Koncentracija trans- i cis-rezveratrola u vinima proizvedenim u Srbiji
(Serbian Chemical Soc, Belgrade, 2008)
Resveratrol, which occurs in two isomeric forms, trans and cis, is a phytoalexin with numerous pharmacological activities, such as anti-cancer, antiviral, neuroprotective and anti-aging. Red wine is the main source of the ...
Mechanics of submerged jet cavitating action: material properties, exposure time and temperature effects on erosion
(Springer, New York, 2008)
Experimental setup with a submerged cavitating jet has been used for the study of influences of material, exposure time and working fluid temperature on the erosion process. Each of the parameters has been varied separately, ...
Temperature dependence of the kinetics of oxygen reduction on carbon-supported pt nanoparticles / Temperaturna zavisnost elektrohemijske redukcije kiseonika na nanočesticama platine na ugljeničnom nosaču
(Serbian Chemical Society, Belgrade, 2008)
The temperature dependence of oxygen reduction reaction (ORR) was studied on highly dispersed Pt nanoparticles supported on a carbon cryo-gel. The specific surface area of the support was 517 m2 g-1, the Pt particles ...
Characterization of microstructural changes in an Al-6.8 wt.% Mg alloy by electrical resistivity measurements
(Elsevier Science Sa, Lausanne, 2008)
Microstructural changes in an AlMg6.8 alloy after different thermo mechanical (TMT) and sensitization treatments were investigated by electrical resistivity measurements. The electrical resistivity was most affected by the ...
Sorption of Pb2+, Cd2+, and Sr2+ ions on calcium hydroxyapatite powder obtained by the hydrothermal method
(Asce-Amer Soc Civil Engineers, Reston, 2008)
The sorption of Pb2+, Cd2+, and Sr2+ ions from aqueous solutions by carbonate-substituted calcium hydroxyapatite (HAP) obtained by the hydrothermal decomposition of urea and calcium-ethylenediaminetetraacetic acid chelates ...
