Size and surface effects on the MRI relaxivity of manganese ferrite nanoparticle contrast agents
(Amer Chemical Soc, Washington, 2007)
Superparamagnetic MnFe2O4 nanocrystals of different sizes were synthesized in high-boiling ether solvent and transferred into water using three different approaches. First, we applied a ligand exchange in order to form a ...
Efficiency of oil removal from real wastewater with different sorbent materials
(Elsevier Science Bv, Amsterdam, 2007)
The aim of this paper was to investigate the efficiency of different sorbent materials for oil removal from wastewater. Two types of sorbents were investigated: organic (loose natural wool fibers (NWF) and recycled wool ...
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 ...
Selective removal of heavy metals from metal-bearing wastewater in a cascade line reactor
(Ecomed Publishers, Landsberg, 2007)
Goal, Scope and Background. This paper is a part of the research work on 'Integrated treatment of industrial wastes towards prevention of regional water resources contamination INTREAT' the project. It addresses the ...
Supercritical carbon dioxide extraction of carrot fruit essential oil: Chemical composition and antimicrobial activity
(Elsevier Sci Ltd, Oxford, 2007)
Isolation of carrot fruit (Daucus carrota L., cultivar "Chanteney") essential oil by supercritical carbon dioxide was investigated from the pretreatment of herbaceous matrix and extraction conditions to the chemical ...
Characterization of microflora in homemade semi-hard white Zlatar cheese
(Elsevier Science Bv, Amsterdam, 2007)
The Zlatar cheese belongs to the group of traditionally homemade cheeses, which are produced from nonpasteurized cow's milk, without adding of any bacterial starter culture. Changes were followed in lactic acid bacteria ...
Immobilization of yeast cells in PVA particles for beer fermentation
(Elsevier Sci Ltd, Oxford, 2007)
In this study, the potential of application of non-aggressive LentiKat (R) technique for brewer's yeast immobilization on polyvinyl alcohol was assessed. High cell loads of about 109 cells/ml were achieved by this procedure ...
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 ...
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 ...
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 ...
