Densities, viscosities, and surface and interfacial tensions of the ternary mixture water plus ethyl butyrate plus methanol at 303.15
(Amer Chemical Soc, Washington, 2003)
The excess molar volumes, V-E, viscosity deviations, Deltaeta, and excess surface tensions were calculated from the measured density, viscosity, and surface tension values, a, over the whole miscibility composition range ...
Development of a microbiosensor based on fish Chromatophores immobilized on ferromagnetic gelatin beads
(University of Zagreb, 2005)
Development of a microbiosensor based on immobilized living chromatophores of Siamese fighting fish, Betta splendens, for the detection of microbial and environmental toxins is described in this paper. Chromatophores were ...
Solidification of High Chromium White Cast Iron Alloyed with Vanadium
(Japan Inst Metals, Sendai, 2011)
Experimental results indicate that vanadium affects the solidification process in high chromium iron. Vanadium is distributed between eutectic M7C3 carbide and the matrix, but its content in carbide is considerably higher. ...
Matrix Microstructure and Its Micro-Analysis of Constituent Phases in As-Cast Fe-Cr-C-V Alloys
(Japan Inst Metals, Sendai, 2009)
The as-cast matrix microstructure in 19 mass%Cr-2.8 mass%C white cast iron with up to 4.7 mass% V additions has been studied. Type and degree of the austenite transformation in the course of cooling after solidification ...
A Kinetic Study of Candida rugosa Lipase-Catalyzed Synthesis of 4,6-Dimethyl-3-cyano-2-pyridone
(Sociedade Brasileira de Química, 2010)
The synthesis of 4,6-dimethyl-3-cyano-2-pyridone was studied in a reaction catalyzed with Candida rugosa lipase. A response surface methodology (RSM) was applied for the optimization of the experimental conditions. The ...
Influence of Reheating Temperature and Vanadium Content on Transformation Behavior and Mechanical Properties of Medium Carbon Forging Steels
(Iron Steel Inst Japan Keidanren Kaikan, Tokyo, 2010)
The influence of vanadium and nitrogen on microstructure and mechanical properties of medium-carbon steels has been studied by means of metallography and mechanical testing. Vanadium addition to the low nitrogen steel ...
Thermal shock damage characterization of high temperature ceramics by non destructive test methods
(University of Chemistry and Technology, Prague, 2008)
In the present work a mixture of commercially available spinel, quartz (SiO2) and alumina (Al2O3) corresponding to cordierite stoichiometry was used as starting material for obtaining cordierite/SiC composite ceramics with ...
Degradation behaviour of PCL/PEO/PCL and PCL/PEO block copolymers under controlled hydrolytic, enzymatic and composting conditions
(Elsevier Sci Ltd, Oxford, 2017)
Short-term hydrolytic and enzymatic degradation of poly(epsilon-caprolactone) (PCL), one series of triblock (PCL/PEO/PCL) and the other of diblock (PCL/PEO) copolymers, with a low content of hydrophilic PEO segments is ...
Synthesis, characterization and biological activity of 2-(5-arylidene-2,4-dioxotetrahydrothiazole-3-yl) propanoic acid derivatives
(Elsevier Science Bv, Amsterdam, 2017)
A series of six novel 2-(5-arylidene-2,4-dioxotetrahydrothiazole-3-yl) propanoic acids and six corresponding methyl esters were synthesized. All compounds were characterized by melting points, elemental analysis, FT-IR, ...
Lipase-Catalyzed Synthesis of Ascorbyl Oleate in Acetone: Optimization of Reaction Conditions and Lipase Reusability
(Japan Oil Chemists Soc, Tokyo, 2013)
Lipase-catalyzed ascorbyl oleate synthesis is eco-friendly and selective way of production of liposoluble biocompatible antioxidants, but still not present on an industrial level due to the high biocatalyst costs. In this ...
