Polimerna optička vlakna / Polymer optical fibres
(Loznica : Viskoza, 1997)
U ovom radu je dat kratak pregled razvoja polimernih optičkih vlakana, kao i njihova klasifikacija. Takodje, razmatrani su fizički principi optičkih talasovoda i njihove prednosti u odnosu na metalne provodnike. Naročita ...
Uticaj inkorporiranog ugljenika na termomehanička svojstva viskoznih vlakana i korda / Influence of incorporate carbon on thermo-mechanical properties of viscose fibres and cord
(Loznica : Viskoza, 1997)
Viskozna vlakna sa inkorporiranim ugljenikom imaju specifična svojstva i namenu. U procesu zagrevanja viskoznih vlakana i korda u prisustvu kiseonika, usled promene kretanja strukturnih elemenata i hemijskih promena, dolazi ...
Kinetic properties of the Ti-Ni intermetallic phases and alloys for hydrogen evolution
(Elsevier Science Sa, Lausanne, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloy electrodes prepared by are-melting and mechanical alloying methods has been studied by means of AC impedance spectrum measurements. The electrode, prepared ...
Corrosion protection of mild steel by polypyrrole coatings in acid sulfate solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The corrosion behaviour of mild steel covered by the electrodeposited polypyrrole films was investigated by electrochemical impedance spectroscopy. Electrodeposition of polypyrrole was performed from aqueous solution of ...
Reversed substituent effect on C=O stretching vibrations in hydantoin derivatives
(Natl Inst Science Communication & Information Resources-Niscair, New Delhi, 1997)
The infrared spectra have been recorded for thirteen 3-substituted-5,5-dimethylhydantoins in the region of fundamental C=O stretching vibrations in dichloromethane. The frequencies of symmetric and asymmetric C=O stretching ...
The effect of deposition process exchange current density on the thin metal film formation on inert substrate
(Serbian Chemical Society, Belgrade, 1997)
The initial stage of thin surface metal film formation on inert substrate is considered. The simultaneous action of both active centers and nucleation exclusion zones was taken into consideration when discussing the ...
Structural investigation of the chabazite like aluminophosphate prepared in the presence of HF.
(Amer Chemical Soc, Washington, 1997)
Quantum approach to GaAs MESFETs
(IEEE, 1997)
This paper is completely devoted to an original method of determination of carriers distribution in GaAs MESFET channel based on the investigation of transport equation including a quantum correction term.
Application of a chitosan/nonionic surfactant mixture to wool assessed by dyeing with a reactive dye
(Society of Dyers and Colourists, 1997)
Chitosan application to wool is known to be associated with problems such as its weak binding and uneven distribution. In an attempt to overcome such problems, chitosan was applied from a mixture with a nonionic surfactant. ...
