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 ...
Influence of microenvironmental conditions on hybridoma cell growth inside the alginate-poly-L-lysine microcapsule
(Elsevier Sci Ltd, Oxford, 2007)
A mathematical model was formulated to describe hybridoma cell growth within the alginate-poly-L-lysine (alginate-PLL) microcapsules during air-lift bioreactor cultivation. Model development was based on experimentally ...
Phenomenological modelling tools for orthopaedic tissue engineering

Analysis of the effects of catalytic bleaching on cotton
(Springer, Dordrecht, 2007)
Hydrogen peroxide can be catalyzed to bleach cotton fibers at temperatures as low as 30 degrees C by incorporating dinuclear tri-mu-oxo bridged manganese(IV) complex of the ligand 1,4,7-trimethyl-1,4,7-triazacyclononane ...
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 ...
Determination of glass temperature of polymers by inverse gas chromatography
(Elsevier, Amsterdam, 2008)
Inverse gas chromatography (IGC) is an attractive technique for polymer characterization due to possible simultaneous determination of various physicochemical properties of polymer systems merely from retention times of ...
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 ...
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, ...
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root
(Elsevier Science Bv, Amsterdam, 2007)
Supercritical carbon dioxide extraction of sesquiterpenes from valerian root was investigated. Extractions from cultivar Arterner zuctung and two wild grown valerian subspecies were performed. The influence of extraction ...
