New Experimental and Mechanistic Investigation on the KSCN-H2O2-NaOH-Cu(II)-Catalyzed Oscillating System (Orban-Epstein Reaction): Inhibitory Effects by Diphenols
(Wiley-Blackwell, Hoboken, 2015)
The KSCN-H2O2-NaOH-Cu(II)-catalyzed system is one of the few reactions in which chemical oscillations can be observed in batch conditions. In the present paper, this oscillating reaction was revisited in a wide range of ...
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 ...
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 ...
Linear free energy relationships of the 1H and 13C NMR chemical shifts in 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)pyridones
(Elsevier, 2009)
Linear free energy relationships (LFER) were applied to the 1H and 13C NMR chemical shifts in 3-cyano-4-(substituted phenyl)-6-phenyl-2(1H)pyridones. The correlation analysis for the substituent-induced chemical shifts ...
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 ...
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 ...
Characterization of double oxide system Cu-Cr-O supported on gamma-Al2O3
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Series of alumina supported chromium-copper catalysts were prepared by co-impregnation method. The samples were characterized by X-ray diffraction, X-ray photoelectron spectroscopy and UV-visible diffuse reflectance ...
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 ...
