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. ...
NMR Characterization and Rietveld Refinement of the Structure of Rehydrated AlPO4-34
(American Chemical Society, 2000)
The triclinic form of AlPO4-34, a microporous aluminophosphate with the chabazite (CHA) topology, adopts a rhombohedral symmetry upon calcination. The framework structure of this phase remains intact under ambient conditions, ...
Manganese leaching in the FeS2-MnO2-O2-H2O system at high temperature in an autoclave
(Elsevier Science Publishers B.V., 2000)
The paper shows: (a) the results of pyrite oxidation by gaseous oxygen in water suspension at high temperatures in an autoclave and (b) the results of simultaneous leaching of Mn4+ from pyrolusite ore by H2SO4 and FeSO4, ...

(Loznica : Viskoza, 2000)
U ovom radu su, na bazi rezultata istraživanja termijskih, termomehaničkih i strukturnih karakteristika polimetilmetakrilata (PMMA), određeni parametri procesa formiranja polimetilmetakrilatnih vlakana specijalnih svojstava. ...
Synthesis and FT-IR Study of Some N-Monosubstituted 2,2-Dimethylpropanamides / Sinteza i FT-IR studija nekih N-mono supstituisanih 2,2-dimetilpropanamida
(Banja Luka : Društvo hemičara i tehnologa Republike SrpskeBanja Luka : Tehnološki fakultet, 2000)
In our study of behaviour of the amide bond we investigated the conformations of some N-monasubstituted 2,2-dimethy|propanamides of the general formula CH3C(CH3)2CONHR, wherein R ranges from n-alkyl (C1-C7), iso-alkyil ...
Mobility of Contaminants originated from Bombing of an Oil rafinery in Serbia
(Proceedings of an International Conference, Protection and Restoration of the Environment V", Thassos, Greece, July 3-6 (2000), 2000)
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 ...
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 ...
Growth study of surfactant-mediated relaxed SiGe graded layers for 1.55-μm photodetector applications
(Elsevier Sequoia SA, 2000)
A systematic study of Sb sufactant-mediated relaxed SiGe graded layers has been performed. The results have been compared
with those of relaxed SiGe layers grown at high temperatures, showing that the Sb-mediated SiGe ...
