Hermal shock behavior of Alumina based refractories: Korrelation between damage resistance parameters and water fcuench test
(Techna Srl, Faenza, 2000)
Klaterials were five alumina based commercial refractories with different content of (AI2O3 +TiO2) from 28% to 78%.The thermal and mechanBl properties of these materials were measured using standard laboratory procedure.Thermal ...
Thermal investigations of CoAPO materials prepared by using piperidine as a structure-directing agent
(Elsevier, Amsterdam, 2000)
Two CoAPO materials (CoAPO-34 and CoAPO-20) with relatively high Co2+/Al3+ substitution level were synthesised in either fluoride-free or fluoride-containing reaction mixture using piperidine as a structure-directing agent. ...
Analysis of in vivo substitution of bone tissue by HAp/PLLA composite biomaterial with PLLA of different molecular weights using FTIR spectroscopy
(Uetikon-Zuerich : Trans Tech Publ, 2000)
Hydroxyapatite/poly-L-lactide (HAp/PLLA) composite biomaterial with PLLA of 50,000 and 430,000 g/mole molecular weight was studied in vivo. The biocomposite with PLLA of both molecular weights was implanted into mice and ...
Alginatna vlakna programirane biološke aktivnosti / Alginate fibers with programmed biologically activity
(Loznica : Viskoza, 2000)
Alginatna vlakna poseduju niz veoma jedinstvenih svojstava i sa aspekta razvijene površine, hidrofilnosti, biokompatibilnosti i netoksičnosti prevazilaze većinu danas poznatih polimera. U ovom radu, alginatna vlakna su ...

Leaching of copper(I) sulfide in calcium chloride solution
(Elsevier, 2000)
Finely grained samples of copper(I) sulphide were leached by CaCl2·2H2O solution with added HCl and the introduction of gaseous oxygen. The occurrence probability of chemical reactions was analyzed based on literature and ...
Experimental study of zinc morphology in alkaline electrolyte at low direct and pulsating overpotentials
(Elsevier Sequoia SA, 2000)
A possible mechanism of the formation of spongy zinc electrodeposits is considered. The confirmation of the proposed semiquantitative mathematical model is performed in zinc electrodeposition onto copper wire from a 0.1 M ...
Modeling boron separation from water by activated carbon, impregnated and unimpregnated
(Roma : Società chimica italiana, 2000)
The sorption of boron from boric acid water solution by impregnated activated carbon has been studied Barium, calcium, mannitol, tartaric acid and citric acid were used as chemical active materials. All processes were ...
Stress field analysis in composite laminates with embedded optical fiber
(Trans Tech Publications Ltd, Durnten-Zurich, 2000)
A typical intensity-modulated optical fiber sensor system consists of a light source, a sensing device, within which the intensity of light is altered by the measurand in some way, a detector to measure the intensity of ...
Contribution to study of processes on the steel cast-sand mould contact surface during casting
(Elsevier Science B.V., 2000)
The testings involved in this paper were part of a comprehensive research project conducted to find out what complex processes were taking place at metal-mould contact surface. These investigations are of particular ...
