Evaluation of heavy metal contamination in sediments using the method of total digestion and determination of the binding forms-Tisa River Basin, Serbia
(Taylor and Francis Inc., 2010)
This paper describes an approach for the evaluation of metal contamination in sediment, using the determination of binding forms of elements (sequential extraction method), the total element content (digestion method), as ...
Synthesis and Structure of New 5-(Arylidene)-3-(4-methylbenzoyl)thiazolidine-2,4-diones
(Wiley-Blackwell Publishing, Inc, Malden, 2010)
The derivatives of 5-substituted-2,4-thiazolidinedione have a broad spectrum of biological activities. In this article, new 5-(arylidene)-3-(4-methylbenzoyl)thiayolidine-2,4-diones 3a-k, with arylidene groups such as ...
STACKING INTERACTIONS BETWEEN PYRIDINE FRAGMENTS IN CRYSTAL STRUCTURES OF TERPYRIDYL COMPLEXES
(Univ Babes-Bolyai, Cluj-Napoca, 2010)
In the crystal structures of terpyridyl complexes from the Cambridge Structural Database (CSD) stacking interaction between the pyridine fragments were studied. Square-planar complexes where the distance between the centers ...
The electrochemical properties of carbon nanotubes and carbon XC-72R and their application as Pt supports / Elektrohemijske karakteristike ugljeničnih nanocevi i ugljenika XC-72R i njihova primena u sintezi Pt katalizatora
(Serbian Chemical Society, 2010)
The results of an investigation of two samples of commercial multi-walled carbon nanotubes and a sample of carbon black, in the raw and activated state, were presented in the lecture. The activation of the carbon materials ...
The impact of Schiff bases on antibiotic production by Streptomyces hygroscopicus
(Medicinal Chemistry Research, 2010)
A media consisting of isatin-Schiff bases (isatin-3-thiosemicarbazone, isatin-3-semicarbazone, and isatin-3-phenylhydrazone) was developed to maximize the production of antibiotics Hexaene H-85 and Azalomycine B by ...
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 ...
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 ...
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 ...
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 ...
Reduction of Oxygen at a NaX-Ag Composite Electrode and Its Application to the Determination of Oxygen in Aqueous Media
(Maik Nauka/Interperiodica/Springer, New York, 2010)
A composite mixture Ag-NaX zeolite (silver concentration 16.7% w/w) is synthesized usingimpregnation and thermal decomposition. For silver impregnation, a solution of an Ag acetylacetonate complex in acetone was used. ...
