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. ...
A New Method to Describe the Multimode Jahn–Teller Effect Using Density Functional Theory
(Springer, Berlin, Heidelberg, 2009)
A new method for the analysis of the adiabatic potential energy surfacesof Jahn–Teller (JT) active molecules is presented. It is based on the analogy betweenthe JT distortion and reaction coordinates. Within the harmonic ...
Enzymatic characterization of 30 kDa lipase from Pseudomonas aeruginosa ATCC 27853
(Journal of Basic Microbiology, 2009)
An extracellular lipase from Pseudomonas aeruginosa ATCC 27853 has been purified and its enzymatic characteristics were determined. According to SDS-PAGE and gel filtration molecular mass estimated to be 30 kDa, what ...
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 ...
Citrate-based zinc-polyaniline secondary cell: Part I: Optimization of the citrate/chloride electrolyte
(Journal of Applied Electrochemistry, 2009)
Electrochemical behavior of zinc and thin polyaniline (PANI) electrodes in citrate/chloride-contained electrolyte has been investigated by the means of electrolyte composition optimization. Electrolyte contained 0.8 M ...
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. ...

Corrosion behavior of magnesium, aluminum and zinc in 0.2 mol dm(-3) NH4Cl; 0.1 mol dm(-3) NH4Cl with addition of 0.1 mol dm(-3) Na-citrate and corrosion behavior of zinc in 0.3 mol dm-3 NH4Cl with addition of 0.8 mol ...
Review of our beneficiation of oil shale by bioprocessing on laboratory scale
(International Oil Shale Symposium, Tallin, Estonia, 8-11 June 2009, 2009)
It is estimated that reserves of oil shale in Serbia amounts to about 3 billion tons while the largest deposit (approx. 2/3 of total amount) for open-pit and underground exploitation is situated in the locality of Aleksinac ...
Synthesis and characterization of silver—poly(methylmethacrylate) nanocomposites
(Springer, 2009)
The optical properties of silver nanoparticles
embedded in poly(methylmethacrylate) (PMMA) was investigated
as well as the influence of silver nanoparticles on
the thermal properties of polymer matrix. The average ...
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 ...
