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 ...
A highly efficient diastereoselective synthesis of alpha-isosalicin by maltase from Saccharomyces cerevisiae
(Elsevier Sci Ltd, Oxford, 2011)
In this report, alpha-isosalicin, a potent anticoagulant and skin whitening agent, was synthesized by a highly efficient chemoselective and diastereoselective reaction, catalyzed by maltase from bakers' yeast (Saccharomyces ...
Electrochemical characterization of polyaniline electrode in ammonium citrate containing electrolyte
(Elsevier Science Sa, Lausanne, 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 ...

(24th European Conference on Biomaterials, EBS 2011, 2011)
Synthesis of antimicrobial monophase silver-doped hydroxyapatite nanopowders for bone tissue engineering
(Elsevier, Amsterdam, 2011)
Monophase silver-doped hydroxyapatite (AgxCa10-x(PO4)(6)(OH)(2); 0.002 lt = x lt = 0.04) nanoparticles were prepared using a neutralization method and investigated with respect to potential medical applications. This ...
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 ...
Deciduous tree leaves in trace elements biomonitoring: A contribution to methodology
(Elsevier Science Bv, Amsterdam, 2011)
Air quality biomonitoring using plant leaves has been widely applied to assess the effects of atmospheric pollution. Although practiced for many years, it has not given completely satisfactory data, due to different and ...
A Voltammetric Method for the Quantitative Determination of Midecamycin Compared to Its Simultaneous HPLC Determination
(Pleiades Publishing Inc, Moscow, 2011)
The aim of this study was to present the quantitative determination of midecamycin at a gold electrode in 0.05 M NaHCO3 using cyclic linear sweep voltammetry. It was found that the value of the oxidative peak of pure ...
