The influence of the aging time of RuO2 and TiO2 sols on the electrochemical properties and behavior for the chlorine evolution reaction of activated titanium anodes obtained by the sol-gel procedure
(Elsevier, 2000)
The influence of the aging time of RuO2 and TiO2 sols used for the preparation of (40% RuO2+60% TiO2)/Ti anodes by the sol-gel procedure on the electrochemical properties and behavior for the chlorine evolution reaction ...
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 ...
Enumeration of labelled quasi-initially connected digraphs
(Elsevier, 2000)
A new class of connected digraphs is introduced - the class of quasi-initially connected digraphs. They are enumerated in the labelled case. Using the apparatus developed for labelled quasi-initially connected digraphs ...
Kinetic analysis of hydrogen evolution at Ni-Mo alloy electrodes
(Elsevier Science Ltd, 2000)
The hydrogen evolution reaction (HER) on Ni, Mo and MoNi intermetallic compound was investigated with ac impedance and dc polarization measurements in 1.0 mol dm-3 NaOH solution at 25 °C. The rate constants of the forward ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
