Preparation and properties of polymeric and composite bioresorbable barrier membranes
(Progress in Advanced Materials and Processes, 5th Conference of the Yugoslav-Materials-Research-Society (Yu-MRS 2003), Sep 15-19, 2003, Herceg Novi, Yugoslavia, 2004)
Bioresorbable barrier membranes have been widely used in dentistry and maxillofacial surgery. When the membranes are placed over bony defects and are closely adapted by the surrounding bone face, an environment that prevents ...
Mechanochemical synthesis of nanostructured fluorapatite/fluorhydroxyapatite and carbonated fluorapatite/fluorhydroxyapatite
(Journal of Solid State Chemistry, 2004)
Powder mixture of Ca(OH)(2)-P2O5-CaF2 were milled in planetary ball mill. A carbonated fluorhydroxyapatite, FHA Ca-10(PO4)(1-y)(CO3)(y)(PO4)(5)(OH)(2-2x1)(F)(2x1) was formed after 5 h of milling and carbonated fluoroapatite ...
Evaluation of hot-pressed hydroxyapatite/poly-L-lactide composite biomaterial characteristics
(Journal of Biomedical Materials Research. Part B: Applied Biomaterials, 2004)
Hydroxyapatite/poly-L-lactide (HAp/PLLA) is a ceramic/polymer composite, whose application as a resorbable biomaterial for the substitution and repair of hard bone tissue is widely promising in orthopedic, oral, maxillofacial, ...
Hydroxyapatite as a root canal system filling material: Cytotoxicity testing
(Durnten-Zurich : Trans Tech Publications Ltd., 2004)
Cytotoxicity testing, as a standard assay for toxicity of dental materials, is useful for initial biocompatibility evaluations. In vitro test of calcium hydroxyapatite (CHA) with established laboratory cell line showed ...
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 ...
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 ...
