Characterization of platinum deposited on carbon hollow fibers / carbon cryogel composites
(Journal of Optoelectronics and Advanced Materials, 2008)
Platinum supported on high surface area carbon material is one of the most intensively studied catalysts. However, physicochemical characteristics and surface chemistry of carbon influence properties of the support itself ...
The electrochemical behavior of commercial clarithromycin and spectroscopic detection of its structural changes
(Pleiades Publishing Inc, Moscow, 2008)
The aim of the present study was to examine the behavior of commercial clarithromycin, Clathrocyn (R), comparing to the results previously obtained using pure clarithromycin under the same experimental conditions. The study ...
Secondary lipid oxidation products of oil in white mustard seeds (sinapis albae semen)
(Scibulcom Ltd, Sofia, 2013)
In this study secondary lipid oxidation products of oil in white mustard seeds were analysed. Ground white mustard seeds were extracted by solvent extraction and the extract was analysed by gas chromatographic-mass ...
Reflection and structural analyses of mirror-bright metal coatings
(Springer, 2004)
Reflection and structural analyses of different copper and zinc coatings were performed. The copper coatings were electrodeposited from a sulfate solution in the presence of thiourea, as well as in the presence of modified ...
Nanostructural Analysis of Mirror – Bright Zinc Coatings
(MAIK "Nauka /Interperiodica" (Russia), 2006)
The zinc coatings electrode posited from solution containing dextrin/salicyl aldehyde mixture are
examined by the scanning tunneling microscopy (STM). It is shown that mirror brightness of these zinc deposits is associated ...
Kinetics of the Formation of Poly(methyldecylsiloxane) by Hydrosilylation of Poly(methylhydrosiloxane) and 1-Decene
(Switzerland : Trans Tech Publications LTD, 2007)
Poly(methylhydrosiloxane) [PMHS], prepared by siloxane equilibration reaction, was used for the hydrosilylation with 1-decene to obtain poly(methyldecylsiloxane) [PMDS]. Pt(0)-1,3-divinyltetramethyldisiloxane complex was ...
Porous glycidyl methacrylate-bentonite composite
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Crosslinked macroporous copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate (CP) and copolymer composite with acid modified clay (CP-S-A) were prepared by radical suspension copolymerization and functionalized ...
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 ...
Mutual influence of parallel, CH/O, OH/pi and lone pair/pi interactions in water/benzene/water system
(Elsevier, 2013)
The mutual influence of OH/pi, CH/O, parallel alignment (all attractive) and lone pair/pi (repulsive) water/benzene interactions was studied with ab initio calculations on water/benzene/water systems. The energies of the ...
