Stability of Metal-Oxide Varistor Characteristics in Exploitation Conditions
(Acta Physica Polonica A, 2009)
Wide-spread use of metal-oxide varistors for non-linearity over-voltage protection results in a variety of possible working conditions. It is therefore essential to have a thorough insight into their reliability in various ...
Bioethanol production from corn meal by simultaneous enzymatic saccharification and fermentation with immobilized cells of Saccharomyces cerevisiae var. ellipsoideus
(Elsevier Sci Ltd, Oxford, 2009)
The simultaneous enzymatic saccharification and fermentation (SSF) of corn meal using immobilized cells of Saccharomyces cerevisiae var. ellipsoideus yeast in a batch system was studied. The yeast cells were immobilized ...
The antibacterial efficiency of polyester fabrics modified by air RF plasma and silver nanoparticles
(University of Gent : Department of Materials, Textiles and Chemical Engineering, 2009)
The aim of this study was to highlight the possibility of using the air RF plasma for fiber surface activation that can facilitate the deposition of silver nanoparticles from colloid onto the polyester fabrics and thus, ...
Application of Complete Gurson Model for prediction of ductile fracture in welded steel joints
(Trans Tech Publications Ltd, Durnten-Zurich, 2009)
Ductile fracture process includes three stages: void nucleation, their growth and coalescence. The voids nucleate due to the fracture or separation of non-metallic inclusions and secondary-phase particles from the material ...
Specific Properties of Polyester Fabrics Functionalized by RF Plasma and Colloidal TiO2 Nanoparticles
(Department of Materials, Textiles and Chemical Engineering, 2009)
This study was aimed to examine the possibility of using RF plasma at low pressure for the surface activation of polyester fabrics in order to improve the binding efficiency of colloidal TiO2 nanoparticles. Colloidal TiO2 ...
Micromechanical estimates of the critical values of j-integral for the steel of steam pipelines
(Springer, New York, 2009)
We analyze the level of damage to 14MoV63 steel for steam pipelines under the conditions of crack-growth initiation according to the mechanism of ductile fracture. The state of the material after service for about 100,000 ...
National background report on Environment for SERBIA
(2009)
The objective of this report is to provide an overview of the environment protection
research in the Republic of Serbia (hereinafter: Serbia), with a SWOT analysis of the
research capacities and identification of ...
Comparative study of differently treated animal bones for Co2+ removal
(Journal of Hazardous Materials, 2009)
The objective of the present study was the evaluation of differently treated bovine bones for Co2+ removal from aqueous media. Powdered bones (B), as well as samples prepared by H2O2 oxidation (BH2O2) and annealing at ...
Thermal deamination kinetics of the nickel-containing chabazite-like aluminophosphate, Ni(NH2-CH2-CH2-NH2)(2)(AlPO4)(6)(OH)(2), deposition of nanocrystalline NiO particles
(Elsevier Science Sa, Lausanne, 2009)
Thermogravimetrical analysis has been used to study the kinetics of thermal deamination of bis(ethylenediamine) nickel(II)-containing aluminophosphate (Ni-CHA) which is a precursor of nickel(II)-containing chabazite-like ...
Nanosilica/PMMA composites obtained by the modification of silica nanoparticles in a supercritical carbon dioxide-ethanol mixture
(Springer, New York, 2009)
Nanosilica/poly(methyl methacrylate) (PMMA) composites are used to improve the mechanical properties of neat PMMA polymer. In order to obtain superior mechanical properties, it is essential to achieve good bonding between ...
