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 ...
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 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 ...
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 ...
Biodiesel synthesis at high pressure and temperature: Analysis of energy consumption on industrial scale
(Elsevier Sci Ltd, Oxford, 2009)
Analysis of several different schemes for industrial FAME production at higher pressure and temperature (catalytic or non-catalytic synthesis) was realized with the aim to find the best route to reduce the energy consumption ...
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 ...
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 ...
Wall-to-bed heat transfer in vertical hydraulic transport and in particulate fluidized beds
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
Wall-to-bed heat transfer in hydraulic transport and in particulate fluidized beds of spherical particles was studied. Experiments were performed by spherical glass particles of 0.80-2.98 mm in diameter with water in a ...
Phenomenological modelling tools for orthopaedic tissue engineering
(European Cells and Materials, 2008)
Real-time magnetic resonance imaging and quantification of lipoprotein metabolism in vivo using nanocrystals
(Nature Publishing Group, London, 2009)
Semiconductor quantum dots and superparamagnetic iron oxide nanocrystals have physical properties that are well suited for biomedical imaging. Previously, we have shown that iron oxide nanocrystals embedded within the lipid ...
