Are C-H center dot center dot center dot O interactions linear? The case of aromatic CH donors
(Royal Soc Chemistry, Cambridge, 2011)
The angular distribution of the C-H center dot center dot center dot O interactions of aromatic C-H donors was studied by analyzing data in the Cambridge Structural Database (CSD) and by ab initio calculations. The analysis ...
Ex situ bioremediation of a soil contaminated by mazut (heavy residual fuel oil) - A field experiment
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Mazut (heavy residual fuel oil)-polluted soil was exposed to bioremediation in an ex situ field-scale (600 m(3)) study. Re-inoculation was performed periodically with biomasses of microbial consortia isolated from the ...
Poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate)/clay composites
(Elsevier Science Sa, Lausanne, 2011)
In this study, macroporous composites of poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) i.e. poly(GMA-co-EGDMA) and clay were prepared by radical suspension copolymerization. The composites with either raw ...
Electrocatalytic behavior of nickel impregnated zeolite electrode
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
In order to enhance nickel effectiveness for methanol oxidation reaction, zeolite type 13X was used as a support for nickel nanodispersion. Nickel modified samples were characterized by XRD, SEM and nitrogen adsorption-desorption ...
Temperature dependence of In1-xGaxSb reflectivity in the far infrared
(Elsevier Science Sa, Lausanne, 2011)
Far infrared reflectivity spectra of polycrystalline In1-xGaxSb were measured and numerically analyzed using the classical dispersion formula and also a fitting procedure based on the modified plasmon-phonon interaction ...
Ethylenediamine-modified multiwall carbon nanotubes as a Pt catalyst support
(Elsevier Science Sa, Lausanne, 2011)
Multi-walled carbon nanotubes (MWCNTs) were used as a support for Pt nanoparticles prepared by the microwave-assisted polyol method. The MWCNTs were pretreated by chemical oxidation (o-MWCNTs) followed by modification by ...
Electrochemical characterization of polyaniline electrode in ammonium citrate containing electrolyte
(Materials Chemistry and Physics, 2011)
Polyaniline electrode (PANI) was formed electrochemically at graphite electrode. Electrochemical polymerization was performed at constant current density of 2.0 mA cm-2 from aqueous solution of 1.0 mol dm -3 HCl with ...
Electrochemical synthesis and characterization of polyaniline thin film and polyaniline powder
(Elsevier Science Sa, Lausanne, 2011)
The polyaniline thin film electrode and powder have been synthesized on graphite electrodes from 0.5 M hydrochloric acid solution under galvanostatic conditions. The water insoluble and acetone soluble polyaniline mass ...
Aliphatic biomarkers and their signal from two hydrogeochemically differing sedimentary environments of the Tertiary Krepoljin Coal Basin (Serbia)
(Springer, New York, 2011)
The sediments of the coal-bearing series of the Tertiary Krepoljin Brown Coal Basin have been investigated and presented in this manuscript. The samples of the intercalated mixed sediments (pieces of coal in clays, sandstones ...
Effects of organic additives on alumina coatings on stainless steel obtained by spray pyrolysis
(Elsevier, 2011)
Alumina coatings were obtained by deposition of boehmite sol, with added polyvinyl alcohol or polyethylene glycol, on stainless steel foil by spray pyrolysis method. Characterizations of coatings were performed by SEM, ...
