Cylindrical-parabolic reflector with printed antenna structures
(Soc Microelectronics, Electron Components Materials-Midem, Ljubljjana, 2013)
The paper presents concept of design and realization of the new class of printed antenna structures which consist of a linear axial array of dipoles, subreflector, feed network and a bal-un, all printed on a common dielectric ...
Thermodynamics of the adsorption of different dyes onto bentonite modified with hexadecyltrimethylammonium cation
(Maik Nauka/Interperiodica/Springer, New York, 2013)
Removal of two different dyes: Acid Orange 10 (AO10) and Reactive Black 5 (RB5) from their aqueous solutions using organobentonite as adsorbent was investigated. The experiments were carried out at different temperatures ...
Mechanistic investigation and DFT calculation of the new reaction between S-methylisothiosemicarbazide and methyl acetoacetate
(Springer/Plenum Publishers, New York, 2013)
A study on the synthesis and mechanistical aspects of formation of 3-methyl-5-oxo-3-pyrazolin-1-carboxamide (MOPC) starting from S-methylisothiosemicarbazide hydrogen iodide and methyl acetoacetate was performed. In the ...
Synthesis, cytotoxic activity and DNA-interaction studies of novel anthraquinone-thiosemicarbazones with tautomerizable methylene group
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2013)
A series of novel anthraquinone thiosemicarbazone derivatives in a tautomerizable keto-imine form was synthesized and tested for their in vitro cytotoxic activity against human cancer cells (HeLa, MDA-MB-361, MDA-MB-453, ...
Speciation of Sr-90 and other metal cations in artificially contaminated soils: the influence of bone sorbent addition
(Springer Heidelberg, Heidelberg, 2013)
The influence of bone sorbent addition onto distribution of Sr-90 in artificially contaminated soil was preliminary studied to assess the possibility of biogenic apatite utilization for reduction of Sr-90 mobility and ...
Synthesis, characterization, and antifungal activity of nystatingum arabic conjugates
(Wiley-Blackwell, Malden, 2013)
Nystatin, a polyene tetraene antibiotic widely used in the treatment of mycoses, was coupled with oxidized polysaccharide gum Arabic, by forming Schiff base structures between amine groups of antibiotics and aldehyde groups ...
The impact of glycerol and some carbohydrates on antibiotic production by Streptomyces hygroscopicus CH-7
(Springer Birkhauser, New York, 2013)
The impact of different carbon sources on the antibiotic production by Streptomyces hygroscopicus CH-7 was studied with the main goal to increase the yield of antibiotics hexaene H-85 and elaiophylin. Glucose, as a basic ...
Crystallographic and ab initio study of pyridine CH-O interactions: linearity of the interactions and influence of pyridine classical hydrogen bonds
(Royal Soc Chemistry, Cambridge, 2013)
The CH-O interactions of pyridine with water molecules were studied by analysing the data in the Cambridge Structural Database (CSD) and by ab initio calculations. The analysis of the CH-O interactions in the crystal ...
Porous carbon thin films for electrochemical capacitors
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Activation effects on carbon films, derived from commercial aromatic polyimide films (Kapton, DuPont), in CO2 atmosphere at 1203 K on capacitance properties were studied. Two thicknesses of polyimide films were used: 7 and ...
A new insight into the mechanism of lead electrodeposition: Ohmic-diffusion control of the electrodeposition process
(Elsevier, 2013)
A new insight into the mechanism of lead electrodeposition from nitrate solutions is presented by analysis of the polarization characteristics and by scanning electron microscopic (SEM) analysis of the surface morphology ...
