Promotional effect of Sn-ad on the ethanol oxidation at Pt3Sn/C catalyst
(Elsevier Science Inc, New York, 2009)
Oxidation of ethanol was studied at Sn-ad modified and unmodified Pt3Sn/C and Pt/C catalysts. Pt3Sn/C and Pt/C catalysts were characterized by XRD. Potentiodynamic and chronoamperometric measurements were used to establish ...
Distribution and fractionation of heavy metals in the Tisa (Tisza) River sediments
(Springer Heidelberg, Heidelberg, 2007)
Introduction. In this work, sediments of the River Tisa (Tisza) are studied to assess their environmental pollution levels for some major heavy metals, as well as to predict the investigated elements' mobility on the basis ...
The qualitative electrochemical determination of clarithromycin and spectroscopic detection of its structural changes at gold electrode
(Elsevier, 2007)
The aim of the present study was the qualitative determination of the pure clarithromycin using a gold electrode in neutral electrolyte by cyclic linear sweep voltammetry. It was shown that in the range of -1.2 V to 1.0 V ...
Oxidation of formic acid on platinum electrodeposited on polished and oxidized glassy carbon
(Elsevier, 2005)
Formic acid oxidation at platinum electrochemically deposited on polished (GC/Pt) and oxidized glassy carbon (GC(ox)/Pt) was examined with the objective of studying the effect of electrochemical treatment of the support ...
Textural and fractal properties of CuO/Al 2 O 3 catalyst supports
(Elsevier, 2006)
Reactive amorphous aluminas with a high surface area, suitable as a precursor for catalyst supports, are obtained by flash calcination of gibbsite in a reactor for pneumatic transport in the dilute two phase flow regime. ...
A Novel Access to Tetrahydro β-Carbolines via One-Pot Hydroformylation / Fischer Indole Synthesis: Rearrangement of 3,3- Spiroindoleninium Cations
(American Chemical Society (ACS), 2008)
The two component one-pot hydroformylation/Fischer indole synthesis sequence of 2,5 dihydropyrroles and phenyl hydrazines allows a facile and convenient access to tetrahydro-β-carbolines in moderate to good yields.
Interaction of Mg enriched kaolinite-bentonite ceramics with arsenic aqueous solutions
(Elsevier, 2009)
Mg-enriched kaolinite–bentonite ceramics prepared in this work exhibited very porous and non-uniform structures, with grain sizes ranging from 1 to 20 μm. During the interaction of this ceramics with aqueous solutions of ...
Magnetoresistance Controls Arboreous Bead-Dendritic Growth of Magnetic Electrodeposits: Experimental and Theoretical Results
(The Electrochemical Society, Inc., 2004)
The effect of magnetic fields applied on magnetic metals electrodeposition was examined. Nickel deposits obtained from a Watt solution with coumarin, at cathodic potentials of -1000, -1200, and -1300 mV/SCE, without and ...
Porosity of different dental luting cements
(Elsevier, 2007)
Objective. The aim of this in vitro study was to compare open porosity and pore size distribution
of different types of luting cements (zinc phosphate and polycarboxylate produced by
Harvard Cement, Great Britain, ...
Application of the Photoacoustic Method for Characterization Of Natural Galena (PbS)
(Springer-Verlag, 2001)
Electron transport properties of single crystal and polycrystalline natural mineral galena (PbS) samples from the Trepča mine, Yugoslavia, were determined using the photoacoustic frequency transmission technique. Their ...
