XRD analysis of calcium phosphate and biocomposite calcium phosphate/bioresorbable polymer
(Recent Developments in Advanced Materials and Processes, 7th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS), Sep 12-16, 2005, Herceg Novi, Montenegro, 2006)
Composite biomaterials based on calcium phosphate ceramic due to their high bioactivity are of interest for biological application and bone tissue repair. Structural and microstructural parameters of inorganic constituent ...
Nanoindentation of in situ polymers in hydroxyapatite/poly-L-lactide biocomposites
(Durnten-Zurich : Trans Tech Publications Ltd., 2006)
In order to obtain more accurate properties after compaction of hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite, high-resolution measurement of mechanical properties method is proposed to determine the properties of ...
Structural and dielectric properties of BaTi1-xSnxO3 ceramics
(Recent Developments in Advanced Materials and Processes, 7th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS), Sep 12-16, 2005, Herceg Novi, Montenegro, 2006)
BaTi1-xSnO3 (BTS) powders, with x ranging from 0 to 1, were synthesized by solid-state reaction technique. The powders were pressed into pellets and sintered at 1370 and 1420 T. The structural characterization of sintered ...
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, ...
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 tribophysical activation on non-isothermal sintering of BaTiO3 ceramics
(Durnten-Zurich : Trans Tech Publications Ltd., 2006)
In this paper the influence of tribophysical activation on non-isothermal sintering of barium titanate has been investigated. BaTiO3 Powders were tribophysically activated in a planetary ball mill for 0, 60 and 120 min., ...
Segmented thermistors printed by NTC nanometric paste and applied in volume air-flow sensors
