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. ...
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 ...
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 ...
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 ...
Far infrared properties of PbTe doped with Hg
(National Institute of Optoelectronics, 2010)
Single crystal samples of PbTe doped with Hg were grown using the Bridgman method. Far infrared reflectivity spectra were measured at room temperature for samples with 0.5 at. % Hg; 0.9 at. % Hg and 1.4 at. % Hg. The plasma ...
Synthesis, structure and solvatochromic properties of 3-cyano-4,6-diphenyl-5-(3- and 4-substituted phenylazo)-2-pyridones / Sinteza, struktura i solvatohromna svojstva 3-cijano-4,6-difenil-5-(3- i 4-supstituisanih fenilazo)-2-piridona
(Serbian Chemical Society, 2010)
A series of some new pyridone arylazo dyes was synthesized from the corresponding diazonium salts and 3-cyano-4,6-diphenyl-2-pyridone using the classical reaction for the synthesis of the azo compounds. The structures of ...
The paramagnetic pillared bentonites as digestive tract mri contrast agents
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
The increased use of imaging techniques in diagnostic studies, such as MRI, has contributed to the development of the wide range of new materials which could be successfully used as image improving agents. However, there ...
Pore surface fractal analysis of PEG and La(III)-doped mesoporous alumina obtained by the sol-gel method / Fraktalna analiza površine mezoporoznog aluminijum(III)-oksida sa dodatkom PEG i La(III) dobijenog sol-gel postupkom
(Serbian Chemical Society, 2010)
Active porous alumina was prepared via a sol-gel method and subjected to thermal treatment in the temperature range 500-1200 °C. The addition of lanthanum effectively inhibited the surface area loss of the aluminas. Fractal ...
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 ...
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 ...
