Nature of structural changes in LSM-YSZ nanocomposite material during thermal treatments
(Elsevier Science Sa, Lausanne, 2004)
Nanocomposite powders in the system (La1-xSx)(a)MnO3-YSZ((1-y)) [LSM-YSZ], as an attractive cathode material for high operating solid oxide fuel cell (SOFC), were obtained through ultrasonic spray pyrolysis (1.7 MHz) method. ...
Mechanochemical synthesis of gamma-Bi2O3
(Amsterdam : Elsevier, 2004)
A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) ...
Electrochemically deposited Ni+WC composite coatings obtained under constant and pulsating current regimes
(Netherlands : Kluwer Academic Publishers, 2004)
A series of Ni+WC composite coatings were obtained by electrodeposition on a rotating disc electrode (RDE)from a commercially available Watts bath containing additives for brightness and smoothing and insoluble WCparticles, ...
The nature of structural changes in nanocrystalline ZnO powders under linear heating conditions
(Oxford : Elsevier Sci, 2004)
The nature of exothermal and irreversible structural changes observed during linear heating of nanocrystalline ZnO powders was investigated using differential scanning calorimetry, X ray, SEM and TEM analysis. Nanocrystalline ...
Dirigovana sinteza nanostrukturnih oksidnih prahova sa gledišta razvoja materijala zadatih svojstava
(Belgrade : University of Belgrade, Faculty of Technology and Metallurgy, 2004)
Razvoj novih materijala, kao i nastojanja za iskorišćenjem njihovih tehnološki atraktivnih karakteristika doveli su do intenzivnije sinteze novih ultrafinih struktura i nanofaznih prahova. Istraživanja obuhvaćena radom ...
Estimation of elastic properties of a particulate polymer composite using a face-centered cubic FE model
(Elsevier, Amsterdam, 2004)
A three-dimensional (3D) finite element (FE) unit cell model is applied to studies on the elastic properties of ceramic spherical particle-polymer composite. In this model, hydroxyapatite particles (HAp) are assumed to be ...
Gibbson: Peptide plane as a unique biological nanostructure
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
In this paper we describe the properties of peptide plane of amino acids from a biophysical point of view. We use Lagrange's equations to calculate the energy states of peptide plain and to explain its biophysical proper-ties. ...
Molecular spectroscopy analysis of the substitution of bone tissue by HAp/PLLA composite biomaterial
(IOS Press, 2004)
Due to its pronounced osteoinductive properties, calcium hydroxyapatite (HAp) has been widely used in medicine. Bioresorptive poly-L-lactide (PLLA) as a polymer biomaterial has been also used extensively in medicine for ...
Biological evaluation of hydroxyapatite/poly‐L‐lactide (HAp/PLLA) composite biomaterials with poly‐L‐lactide of different molecular weights intraperitoneally implanted into mice
(IOS Press, 2004)
Histopathologic analysis of the tissue with HAp/PLLA implants was made and the leukocyte formula and chemiluminescence response of peritoneal phagocytes 2, 7 and 12 weeks after intraperitoneal implantation studied. Implants ...
Synthesis and application of hydroxyapatite/polylactide composite biomaterial
(Elsevier BV, 2004)
Hydroxyapatite/bioresorbable-polymer composite biomaterials can be used for the bone tissue reconstruction. There are different methods to obtain hydroxyapatite/poly-l-lactide (HAp/PLLA) composite biomaterial, but up to ...
