Characterization of electrochemically synthesized PANI on graphite electrode for potential use in electrochemical power sources
(Materials Chemistry and Physics, 2009)
Polyaniline (PANI) on graphite electrode was synthesized electrochemically under galvanostatic condition at current density of 2.0 mA cm-2 from aqueous solution of 1.0 mol dm-3 HCl and 0.25 mol dm-3 aniline monomer. ...
Synthesis and characterization of conducting self-assembled polyaniline nanotubes/zeolite nanocomposite
(Langmuir, 2009)
Self-assembled conducting, paramagnetic polyaniline nanotubes have been synthesized by the oxidative polymerization of aniline with ammonium peroxydisulfate in aqueous medium in the presence of zeolite HZSM-5, without added ...
Study on fisetin-aluminium(III) interaction in aqueous buffered solutions by spectroscopy and molecular modeling
(Elsevier Science Inc, New York, 2009)
Spectroscopic (UV/visible and IR) and theoretical studies were used to assess relevant interaction of fisetin, a tetrahydroxylated flavone molecule, and trivalent aluminium in a wide range of buffered aqueous solutions. ...
Synthesis, characterization and antimicrobial activity of Co(II), Zn(II) and Cd(II) complexes with N-benzyloxycarbonyl-S-phenylalanine
(Elsevier France-Editions Scientifiques Medicales Elsevier, Issy-Les-Moulineaux, 2009)
In this paper the first complexes of M2+ ions (M2+ = Zn2+, Cd2+ and Co2+) with N-benzyloxycarbonyl-S-phenylalaninato ligand (1-3) are described. The new complexes were characterized by means of elemental analysis, IR and ...
Density functional theory study of the Jahn-Teller effect in cobaltocene
(Int Union Pure Applied Chemistry, Res Triangle Pk, 2009)
A detailed discussion of the potential energy surface of bis(cyclopentadienyl)cobalt(II), cobaltocene, is given. Vibronic coupling coefficients are calculated using density functional theory (DFT). Results are in good ...
Al,Cu-pillared clays as catalysts in environmental protection
(Elsevier Science Sa, Lausanne, 2009)
In order to perform water purification from toluene Al,Cu-pillared clay (PILC) was synthesized and tested as catalyst in the oxidation of toluene. Two different catalytic reactions at moderate temperatures were investigated: ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt"Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
Organocatalyzed Tsuji-Trost reaction: a new method for the closure of five- and six-membered rings
(Oxford : Pergamon-Elsevier Science Ltd, 2009)
A combination of organotransition metal catalysis and organocatalysis allows for Tsuji-Trost 5-exo- and 6-exo-cyclizations of aldehydes. This transformation can also be accomplished as a catalytic asymmetric reaction, which ...
Mass transfer in vertical liquid-solids flow of coarse particles
(Powder Technology, 2009)
Wall-to-bed mass transfer in the hydraulic transport of spherical glass particles was studied. The experiments were performed by transporting spherical glass particles 1.20, 1.94 and 2.98 mm in diameter with water in a ...
Removal of N-terminal peptides from β-lactoglobulin by proteolytic contaminants in a commercial phenol oxidase preparation
(International Dairy Journal, 2009)
The use of enzymes may improve the functional properties of various food ingredients. The aim of this study was to examine the effects of proteolytic contaminants in phenol oxidases on β-lactoglobulin (BLG). In the presence ...
