The formation and characterization of nanocrystalline phases by mechanical milling of biphasic calcium phosphate/poly-L-lactide biocomposite
(Materials Transactions. JIM / Japan Institute of Metals, 2006)
Biphasic calcium phosphate/poly-L-lactide granules of 150-200 mu m sizes were subjected to high-energy mechanical milling in a planetary ball mill for up to 480 minutes. Characterization of the material obtained was carried ...
Geometrical and electrical properties of NTC polycrystalline thermistors vs. Changes of sintering parameters
(Belgrade : International Institute for the Science of Sintering, 2006)
NTC thermistor powder was made of a Mn, Ni, Fe and Co oxide mixture calcinated at 1050°C / 60 min. The powder was milled in a ball mill down to an average particle diameter of 0.9 μm. Small disc shaped pills of the powder ...
A kinetic study of D-glucose oxidation by bromine in aqueous solutions
(Oxford : Elsevier Sci Ltd., 2006)
The kinetics of the oxidation Of D-glucose to D-gluconic acid by bromine in aqueous solution were studied using potentiometric techniques and theoretical considerations of complex bromine-bromide-pH equilibria. The pH has ...
Thermal diffusivity and electron transport properties of NTC samples obtained by the photoacoustic method
(Lausanne : Elsevier Science, 2006)
Thermal diffusivity and electron transport parameters of sintered NTC samples were determined by the photoacoustic (PA) technique. Powder mixtures composed of MnO, NiO, CoO and Fe2O3 were milled to nanometer particle size. ...
Hydrogen evolution on Ni/WC composite coatings
(Springer, 2006)
The catalytic activity for the hydrogen evolution reaction (HER) of Ni/WC composites obtained by electrochemicaldeposition of nickel from a conventional Watt’s bath, using two different ways of depositing the WC particles, ...
Magnetic properties of nanostructured SiOo2:Eu3+ powders
(Belgrade : Serbian Chemical Society, 2006)
Eu-doped silica nanoparticles with different concentrations of europium (3% 6%and 15at.%) were prepared by a hydrothermal procedure. Light scattering measurements of the silica colloids as well as TEM microscopy, revealed ...
Investigation of HeNe laser therapy influence on BCP/PLGA osseointegration: Experimental study
(Niš : University of Niš, 2006)
The efficiency of HeNe laser application in treatment of artificially caused bone defects in mandible of rats filled with biocomposite BCP/PLGA (bicalcium phosphate/polylactide-co-glycolide) was analyzed. Animals were ...
Classical and quantum information channels in protein chain
(Trans Tech Publications Ltd, Stafa-Zurich, 2006)
Investigation of the properties of peptide plane in protein chain from both classical and quantum approach is presented. We calculated interatomic force constants for peptide plane and hydrogen bonds between peptide planes ...
Cytotoxicity and fibroblast properties during in vitro test of biphasic calcium phosphate/poly-dl-lactide-co-glycolide biocomposites and different phosphate materials
(Wiley, 2006)
Reconstruction of bone defects is one of the major therapeutic goals in various clinical fields. Bone replacement materials must satisfy a number of criteria. Biological criteria are biocompatibility, controlled biodegradability, ...
The Influence of Milling Conditions on Mechanochemical Synthesis and Sintering of Zinc Titanate
(Kyiv : G. V. Kurdyumov Institute for Metal Physics of the National Academy of Sciences of Ukraine, 2006)
The aim of this work was an investigation of experimental conditions for mechanochemical synthesis and sintering of spinel zinc titanate (Zn2TiO4). Starting powder mixtures of zinc oxide and titan dioxide in the molar ...
