The qualitative electrochemical determination of clarithromycin and spectroscopic detection of its structural changes at gold electrode
(Elsevier Science Inc, New York, 2007)
The aim of the present study was the qualitative determination of the pure clarithromycin using a gold electrode in neutral electrolyte by cyclic linear sweep voltammetry. It was shown that in the range of -1.2 V to 1.0 V ...
Dynamic mechanical properties and in vitro bioactivity of PHBHV/HA nanocomposite
(Elsevier Sci Ltd, Oxford, 2007)
Biopolymer composite materials for potential medical applications are of current research interest. In this study, a nanocomposite based on bioresorbable polymer-poly(3-hydroxybutyrate-co-3-hydroxyvalerate) (PHBHV) was ...
Biosorption of heavy metal ions from aqueous solutions by short hemp fibers: Effect of chemical composition
(Elsevier Science Bv, Amsterdam, 2009)
Sorption potential of waste short hemp fibers for Pb2+, Cd2+ and Zn2+ ions from aqueous media was explored. In order to assess the influence of hemp fiber chemical composition on their heavy metals sorption potential, ...

Determination of selected pesticides in fruit juices by matrix solid-phase dispersion and liquid chromatography-tandem mass spectrometry
(Elsevier Sci Ltd, Oxford, 2009)
A rapid and sensitive liquid chromatography-tandem mass spectrometry method has been developed for the analysis of acephate, monocrotophos, carbendazim, acetamiprid, dimethoate, simazine, carbofuran, atrazine, diuron, DNOC ...
Synthesis, characterization and electrocatalytic activity for ethanol oxidation of carbon supported Pt, Pt-Rh, Pt-SnO2 and Pt-Rh-SnO2 nanoclusters
(Elsevier Science Inc, New York, 2009)
Nanoclusters of Pt, Pt-Rh, Pt-SnO2 and Pt-Rh-SnO2 were successfully synthesized by polyol method and deposited on high-area carbon. HIRTEM and XRD analysis revealed two phases in the ternary Pt-Rh-SnO2/C catalyst: solid ...
Micromechanical properties of a hydroxyapatite/poly-L-lactide biocomposite using nanoindentation and modulus mapping
(Elsevier Sci Ltd, Oxford, 2007)
Biocomposites with ceramic fillers and polymer matrix are becoming attractive materials for bone tissue replacements. Nanoindentation has been used to locally characterize the surface mechanical properties of the ...
Bioreactor cultivation conditions modulate the composition and mechanical properties of tissue-engineered cartilage
(Wiley, Hoboken, 1999)
Cartilaginous constructs have been grown in vitro with use of isolated cells, biodegradable polymer scaffolds, and bioreactors. In the present work, the relationships between the composition and mechanical properties of ...
