Non-isothermal crystallization of k2o center dot tio2 center dot 3geo(2) glass
(Springer, Dordrecht, 2009)
The crystallization of K2O center dot TiO2 center dot 3GeO(2) glass under non-isothermal condition was studied. In powdered glass with particle sizes less than 0.15 mm, surface crystallization was dominant and an activation ...
A comparative study of the electrochemical properties of carbon nanotubes and carbon black
(Elsevier Science Sa, Lausanne, 2009)
Two samples of commercial multi-walled carbon nanotubes (Sigma-Aldrich and Sun Nanotech) and a sample of carbon black (Vulcan XC-72R) were investigated in raw state and after the activation in nitric and sulfuric acid by ...
A Comparative LSER Study of the Reactivity of 2-Substituted Cyclohex-1-eneacetic and 2-Substituted Phenylacetic Acids with Diazodiphenylmethane in Various Solvents
(Wiley, Hoboken, 2009)
The rate constants for the reaction of 2-substituted cyclohex-1-eneacetic and 2-substituted phenylacetic acids with diazodiphenylmethane were determined in various aprotic solvents at 30 degrees C. To explain the kinetic ...
The nucleation behavior of k2o center dot tio2 center dot 3geo(2) undercooled melt
(University of Chemistry and Technology, Prague, 2009)
The nucleation of K2TiGe3O9 crystals in an undercooled melt of stoichiometric composition was studied. Volume nucleation with spherical morphology of the growing crystals was determined. The nucleation range is in the ...
The study of coloration and antibacterial efficiency of corona activated dyed polyamide and polyester fabrics loaded with Ag nanoparticles
(Korean Fiber Soc, Seoul, 2009)
The aim of this study was to examine the influence of dyeing on antibacterial efficiency of corona activated polyamide and polyester fabrics loaded with colloidal Ag nanoparticles as well as the influence of the presence ...
Biosynthesis of ethyl caproate and other short ethyl esters catalyzed by cutinase in organic solvent
(Elsevier Science Bv, Amsterdam, 2009)
The main objective of this work was to study the enzymatic synthesis of short chain ethyl esters, a group of relevant aroma molecules, by Fusarium solani pisi cutinase in an organic solvent media (iso-octane), and to assess ...
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 ...
One-bath One-dye Class Dyeing of PES/Cotton Blends after Corona and Chitosan Treatment
(Korean Fiber Soc, Seoul, 2009)
In this work, the effects of corona discharge (CD) and chitosan treatment on the dyeability of polyester/cotton blends with direct and reactive dyes were studied. The surface chemical changes of polyester and cotton were ...
Wood-Thermoplastic Composites Based on Industrial Waste and Virgin High-Density Polyethylene (HDPE)
(Taylor & Francis Inc, Philadelphia, 2009)
This article investigated the water resistance, mechanical and thermal properties, and the microstructure of wood-plastic composites, which were made by hot pressing using either virgin or high-density polyethylene (HDPE) ...
Catalytic Degradation Processes and Swelling of Alginate Bio-Medical Gels under Influence of Oxygen
(Taylor & Francis Inc, Philadelphia, 2009)
Interaction of cells with polymer networks in nanostructured devices as alginate beads for cell immobilization are considered. Influence of process parameters as oxygen concentration inside a bead on changes of alginate ...
