The effect of agitation intensity on alkali-catalyzed methanolysis of sunflower oil
(Elsevier, 2007)
The sunflower oil methanolysis was studied in a stirred reactor at different agitation speeds. The measurements of drop size, drop size distribution and the conversion degree demonstrate the effects of the agitation speed ...
High activity of Pt4Mo alloy for the electrochemical oxidation of formic acid
(Amer Chemical Soc, Washington, 2007)
Surface processes on Pt4Mo alloy well-defined by X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were studied in acid solution by cyclic voltammetry. It was established that Mo in the alloy is much more ...
Influence of an antimicrobial treatment on the strength properties of polyamide/elastane weft-knitted fabric
(Wiley, Hoboken, 2007)
Polyamide/elastane weft-knitted fabric, as a suitable compression material, was treated with gentamicin sulfate and a natural antimicrobial preparation of the autochthonous essential oil of Picea abies. The antimicrobial ...
Recycled Wool-based Nonwoven Material for Decolorisation of Dyehouse Effluents
(Meta Basim Press, 2007)
The aim of this study was investigate the possible application of recycled wool-based nonwoven material for removal of different dyes that are used in textile dyehouses. Basic, reactive, direct and metal complex dyes were ...
Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded
(Trans Tech Publications Ltd, Durnten-Zurich, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length ...
Phenomenology of a formation of a honeycomb-like structure during copper electrodeposition
(Journal of Solid State Electrochemistry, 2007)
In this paper, the phenomenology of a formation of a honeycomb-like structure was considered. Copper deposits obtained at overpotential of 1000 mV were examined by scanning electron microscopy (SEM) technique. It was shown ...
Removal of volatile organic compounds from activated carbon by thermal Desorption and catalytic combustion
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The thermal desorption of saturated activated carbon discharged from an industrial adsorber and catalytic oxidation of desorbed products over a Pt/Al2O3 catalyst were investigated. The activated carbon is almost completely ...
Contribution of lactic acid fermentation to improved nutritive quality vegetable juices enriched with brewer's yeast autolysate
(Elsevier Sci Ltd, Oxford, 2007)
Vegetables are rich sources of the biologically active compounds which have beneficial effects in prevention of some diseases and certain types of cancer. From the point of view of protection and health, the objective of ...
Effect of silane coupling agents on mechanical properties of Nano-SiO2 filled high-density polyethylene composites
(Zurich : Trans Tech Publications, 2007)
Composites with nano-SiO2 particles and high density polyethylene (HDPE) matrix were produced by hot pressing with various particle contents and particle surface treatment using commercially available silane coupling agents: ...
Amino-functionalized glycidyl methacrylate based macroporous copolymers as metal ion sorbents
(Nova Science Publishers, 2007)
Four samples of macroporous crossliaked poly(glycidyl methacry late-co-ethy lene glycol dimethacrylate), poly(GMA-co-EGDMA), were synthesized by suspension copolymerization and functionalized by ring-opening reaction of ...
