Quantitative structure-toxicity relationship study of some natural and synthetic coumarins using retention parameters / Analiza zavisnosti strukture i toksičnosti nekih prirodnih i sintetičkih kumarina korišćenjem retencionih parametara
(Serbian Chemical Soc, Belgrade, 2012)
Four lipophilicity descriptors (R-M(0), b, C-0 and PCl) for twelve coumarin derivatives were determined by reversed-phase thin-layer chromatography in order to analyze the descriptor which best describes the lipophilicity ...
Electrochemical Characterization of Oxaprozin on Bare Gold Electrode and Electrode Modified with Bovine Serum Albumin
(Esg, Belgrade, 2012)
As the very first electrochemical investigation of oxaprozin, nonsteroidal anti-inflammatory drug, using cyclic voltammetry on gold electrode in 0.05 mol dm(-3) NaHCO3, the synthesized drug, its analytical standard and its ...
RP TLC-Based Lipophilicity Assessment of Some Natural and Synthetic Coumarins
(Soc Brasileira Quimica, Sao Paulo, 2012)
The lipophilic character of twelve coumarins was investigated by reversed-phase thin-layer chromatography (RP TLC) on RP-18 silica. The three different binary solvent systems composed of water and organic modifier (methanol, ...
Antioxidant enzymes and GST activity in natural populations of Holandriana holandrii from the Bosna River
(Tubitak Scientific & Technical Research Council Turkey, Ankara, 2012)
Specimens of the freshwater snail Holandriana holandrii affected by different levels of contamination were collected from 3 sites within the Bosna River Basin, i.e. Visoko, Doboj, and Modrica. The activities of antioxidant ...
Intrinsic Potential-Dependent Performances of a Sol-Gel-Prepared Electrocatalytic IrO2-TiO2 Coating of Dimensionally Stable Anodes
(Springer, New York, 2012)
The electrochemical properties of a sol-gel-prepared IrO2-TiO2 coating on Ti were investigated from the standpoint of the charging/discharging behavior in 1.0A degrees mol dm(-3) H2SO4 and in 0.50A degrees mol dm(-3) NaCl, ...
Surface plasmon resonance of Ag organosols: Experimental and theoretical investigations / Rezonance površinskih plazmona organosola srebra - eksperimentalna i teorijska ispitivanja
(Association of Chemical Engineers of Serbia, 2012)
The aim of this study was to investigate and compare the changes in surface plasmon resonance (SPR) of silver (Ag) hydrosol and organosols obtained by experimental and theoretical approaches. Silver nanoparticles (Ag NPs) ...
Electrical Conductivity of Lignocellulose Composites Loaded with Electrodeposited Copper Powders. Part III. Influence of Particle Morphology on Appearance of Electrical Conductive Layers
(Esg, Belgrade, 2012)
The electrical conductivity of the system based on lignocellulose (LC) biopolymer matrix filled with electrodeposited copper powder has been studied. Galvanostatically produced copper powder, having highly porous, highly ...
Far infrared and photoacoustic characterization of iodine doped PbTe
(National Institute of Optoelectronics, 2012)
Single crystal samples of PbTe doped with PbI2 were made using the Bridgman technique. Far infrared reflectivity diagrams of PbTe doped with 0.4 at% and 0.6 at% Iodine were measured and numerically analyzed. A plasma ...
