Preparation, characterization and X-ray analysis of [Co2(Cl)2tpmc](BF4)2. Comparative structural analysis with the complexes having analogous geometries and ligands
(Elsevier, 2007)
A novel binuclear Co(II) complex, [Co2(Cl)2tpmc](BF4)2 (tpmc = N,N′,N″,N‴-tetrakis(2-pyridylmethyl)-1,4,8,11-tetraaz acyclotetradecane), was prepared and structurally characterized by X-ray diffraction analysis at low ...
beta-Carotene removal from soybean oil with smectite clay using central composite design
(Maik Nauka/Interperiodica/Springer, New York, 2009)
In this study removal of beta-carotene from soybean oil by adsorption on acid activated smectite clay from Serbia was investigated and a factorial 2(3) experimental design was applied. The effects of relevant factors, such ...
A Voltammetric Method for the Quantitative Determination of Midecamycin Compared to Its Simultaneous HPLC Determination
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The aim of this study was to present the quantitative determination of midecamycin at a gold electrode in 0.05 M NaHCO(3) using cyclic linear sweep voltammetry. It was found that the value of the oxidative peak of pure ...
Artemisinins and synthetic peroxides as highly efficient antimalarials
(Soc Chemists Technologists Madeconia, Skopje, 2012)
Malaria is devastating disease and global public health problem, with nearly half world population exposed to risk. Illness is caused by five Plasmodium species, P falciparum, P ovale, P viva; P malaria and P knowlesi, ...
Intrinsic Distortion Path in the analysis of the Jahn-Teller effect
(Elsevier, 2010)
The multideterminental-DFT approach was performed in order to calculate the Jahn-Teller (JT) parameters for the JT active molecules. Within the harmonic approximation the JT distortion can be analysed as a linear combination ...
Polyphenolic compounds in seeds from some grape cultivars grown in Serbia / Polifenolna jedinjenja iz semenki osam sorti grožđa gajenih u Srbiji
(Serbian Chemical Soc, Belgrade, 2010)
Seed extracts from eight grape cultivars (Vitis vinifera) growing in Serbia were screened for their polyphenolic composition by means of HPLC/ /PDA/ESI/MS analysis. The study revealed 34 phenolic compounds belonging to the ...
Characterization of copper powder particles obtained by electrodeposition as function of different current densities
(Journal of Applied Electrochemistry, 2009)
Technological properties of powders depend on their granulometry and morphology. Very often one method is inadequate for characterization of powder particles. This article studied different methods intended for clear ...
A trapezoidal microstrip bandstop filter with efficient suppression of undesired stopbands
(National Institute of Optoelectronics, 2010)
A new bandstop filter implemented as a cascade of trapezoidally shaped cells is presented. The proposed bandstop filter suppresses many undesired stopbands at higher frequencies. The cell design is specified by two variables ...
Decorated Ru/Au(111) and Os/Au(111) surfaces: An in situ STM and electrochemistry study
(Russia : Maik Nauka-Interperiodica Publishing, 2006)
The structure and reactivity of bimetallic electrodes obtained by spontaneous deposition of Ru and Os on Au(111) single-crystal surfaces are studied. In situ electrochemical STM and cyclic voltammetry are used to characterize ...
Hydrogen Evolution on Columnar Ni Thin Films Obtained by GLAD
(Esg, Belgrade, 2017)
Nanostructured nickel thin films were deposited on glass using glancing angle deposition (GLAD) technique. Cross-sectional field emission scanning electron microscopy images have shown that obtained Ni thin films consist ...
