Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Lausanne : Elsevier Science, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
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 ...
