Resource recovery of animal bones: Study on sorptive properties and mechanism for Sr2+ ions
(Elsevier, 2010)
The interaction between Sr2+ ions and variously treated animal bones was studied from the aspect of Sr-90 isotope immobilization from the contaminated effluents. As a source of biogenic, poorly-crystalline apatite, bone ...
Synthesis, characterization and application of poly(N-isopropylacrylamide-co-itaconic acid) hydrogels as supports for lipase immobilization
(Elsevier Science Bv, Amsterdam, 2010)
Temperature- and pH-sensitive hydrogels based on N-isopropylacrylamide (NiPAAm) and itaconic acid (IA) were applied for immobilization of lipase from Candida rugosa (CRL). The hydrogels were synthesized by free radical ...
Modeling the kinetics of calcium hydroxide catalyzed methanolysis of sunflower oil
(Elsevier, 2010)
The kinetics of Ca(OH)2-catalyzed methanolysis of sunflower oil was studied at a moderate temperature (60 °C), a methanol-to-oil molar ratio (6:1) and different catalyst amounts (from 1% to 10% based on oil weight). The ...
Hydrogels of N-isopropylacrylamide copolymers with controlled release of a model protein
(Elsevier Science Bv, Amsterdam, 2010)
Temperature- and pH-sensitive hydrogels, based on N-isopropylacrylamide (NiPAAm) and itaconic acid (IA), were synthesized by free radical crosslinking copolymerization in the presence of lipase from Candida rugosa. The ...
Analysis of welded tensile plates with a surface notch in the weld metal and heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The behavior of the plates with a surface notch under tensile external loading is experimentally and numerically analyzed. The specimens were made of micro-alloyed steel NIO-MOL 490 K. welded by MAC (CO2) welding method. ...
Thermal stability and degradation of Co(II), Cd(II), and Zn(II) complexes with N-benzyloxycarbonylglycinato ligand
(Springer, Dordrecht, 2010)
Thermal behavior of Co(II), Cd(II), and Zn(II) complexes with N-benzyloxycarbonylglycinato ligand was investigated using the results of TG, DSC and DTG analysis obtained at different heating rates (2.5 to 30 A degrees C ...
Ultrasound-assisted production of bioethanol by simultaneous saccharification and fermentation of corn meal
(Elsevier Sci Ltd, Oxford, 2010)
An ultrasound-assisted liquefaction as a pretreatment for bioethanol production by simultaneous saccharification and fermentation (SSF) of corn meal using Saccharomyces cerevisiae var. ellipsoideus yeast in a batch system ...
Production of bioethanol from corn meal hydrolyzates by free and immobilized cells of Saccharomyces cerevisiae var. ellipsoideus
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The ethanol fermentation of enzymatically obtained corn meal hydrolyzates by free and immobilized Saccharomyces cerevisiae var. ellipsoideus yeast in a batch system was studied. The initial glucose and inoculum concentration ...
Degradation of the Insulating System of Power Transformers by Copper Sulfide Deposition: Influence of Oil Oxidation and Presence of Metal Passivator
(Amer Chemical Soc, Washington, 2010)
Deposition of conductive copper sulfide on paper insulation of power transformers was recognized as a serious risk that can result in equipment failure. The aim of this study was to investigate the influence of mineral ...
Production of Bioethanol by Simultaneous Saccharification and Fermentation of Corn Meal by Immobilized Yeast
(Aidic Servizi Srl, Milano, 2010)
The production of bioethanol by simultaneous saccharification and fermentation (SSF) of corn meal using immobilized cells of Saccharomyces cerevisiae var. ellipsoideus yeast in a batch system was studied in this work. The ...
