Enhanced activity in ethanol oxidation of Pt3Sn electrocatalysts synthesized by microwave irradiation
(Maik Nauka/Interperiodica/Springer, New York, 2011)
High surface area carbon supported Pt and Pt3Sn catalysts were synthesized by microwave irradiation and investigated in the ethanol electro-oxidation reaction. The catalysts were obtained using a modified polyol method in ...
Conservation of resources in the pulp and paper industry derived from cleaner production approach
(Resources Conservation and Recycling, 2011)
This paper analyses the utilization of water and recycled fiber from waste paper for the production in one Serbian cardboard mill. Water and fiber consumption, wastewater generation and its characteristics, as well as ...
Durability of sulfur concrete in various aggressive environments
(Elsevier Sci Ltd, Oxford, 2011)
Durability of sulfur concrete with different fillers, as well as Portland cement concrete, was tested in the solutions of HCl, H(2)SO(4), and NaCl. Regarding mass changes, in the solutions of HCl and H(2)SO(4) sulfur ...
The analysis of simultaneous clove/oregano and clove/thyme supercritical extraction
(Elsevier, Amsterdam, 2011)
The goal of present work was to investigate and explain kinetics and mass transfer phenomena occurring during the SFE from the mixture of two plants with different initial composition. The extractions from pure clove, ...
Application and validation of ion chromatography for the analysis of power plants water: Analysis of corrosive anions in conditioned water-steam cycles
(Elsevier, Amsterdam, 2011)
In this study, the possibility of monitoring ion species that could cause corrosion processes in the thermal power plant (TPP) using suppressed ion chromatography (SIC) was investigated. An ion chromatography method for ...
Reactivation of a thermostable lipase by solid phase unfolding/refolding Effect of cysteine residues on refolding efficiency
(Elsevier Science Inc, New York, 2011)
Lipase from Geobacillus thermocatenulatus (BTL2) was immobilized in two different matrixes. In one derivative, the enzyme was immobilized on agarose activated with cyanogen bromide (CNBr-BTL2) via its most reactive superficial ...
Investigation of gas transport through porous membranes based on nonlinear frequency response analysis
(Springer, New York, 2011)
Theoretical development of a new experimental method for investigation of mass transport in porous membranes, based on the principle of the modified Wicke-Kallenbach diffusion cell and the nonlinear frequency response ...
Solvent Effects on the Structure-Property Relationship of Some Potentially Pharmacologically Active 3-(4-Substituted Benzyl)-5-Ethyl-5-Phenyl- and 3-(4-Substituted Benzyl)-5,5-Diphenylhydantoins
(Springer/Plenum Publishers, New York, 2011)
Two series of 3-(4-substituted benzyl)-5-ethyl-5-phenyl- and 3-(4-substituted benzyl)-5,5-diphenylhydantoins were synthesized and their UV absorption spectra were recorded in the region 200-400 nm in selected solvents of ...
Evaluation of the Lipophilicity and Prediction of Biological Activity of Some N-Cyclohexyl-N-Substituted-2-Phenylacetamide Derivatives Using RP-TLC
(Akademiai Kiado Zrt, Budapest, 2011)
The chromatographic behavior of N-cyclohexyl-N-substituted-2-phenylacetamides was investigated using reversed phase thin-layer chromatography (RP-TLC). RP-TLC was performed on a C-18 bonded phase with different aqueous ...
Electrochemical synthesis and corrosion behavior of polyaniline-benzoate coating on copper
(Elsevier Science Sa, Lausanne, 2011)
Electrochemical polymerization of polyaniline (PANI) coating on copper electrode was performed galvanostatically in the current density range between 0.50 and 1.25 mA cm(-2), from aqueous solution of 0.3 mol dm(-3) sodium ...
