A CoAPO-34 derived from a triclinic precursor prepared in the presence of HF
(Elsevier Science Inc., 1997)
The fluoride route of synthesis of AIPO,-34 is also successful in the preparation of its cobalt modified product (CoAPO-34). The triclinic precursor of CoAPO-34 has been synthesized in the presence of HF and piperidine. ...
The influence of permanent dipole moments on second harmonic generation in asymmetric semiconductor quantum wells
(Elsevier, Amsterdam, 1997)
The influence of permanent dipole moments on intersubband double resonance second harmonic generation in asymmetric quantum wells is analyzed. It is found that in realistic QWs matched for 10.6 mu m pump the permanent ...
Benzylation of N-phenyl-2-phenylacetamide
(Natl Inst Science Communication, New Delhi, 1997)
Benzylation of N-phenyl-2-phenylacetamide with benzyl chloride in the presence of powdered KOH has been carried out to find out the possible reaction products as well as to ascertain optimal reaction conditions for the ...
Kinetics of O-2 reduction on a Pt electrode covered with a thin film of solid polymer electrolyte
(Electrochemical Soc Inc, Pennington, 1997)
The kinetics of O-2 reduction on both oxidized and reduced Pt rotating disk surfaces covered with thin films (1 to 15 mu m) of recast polybenzimidazole (PBI) or Nafion have been examined in 0.1 M aqueous solutions of H3PO4, ...

Gas Chromatographic Retention Indices for the N-methyl-N-substituted Benzamides on Capillary Columns, Molecular Retention Index / Gasno hromatografski molekularni retencioni indeks N-metil-N-supstituisanih benzamida
(Banja Luka : Društvo hemičara i tehnologa Republike SrpskeBanja Luka : Tehnološki fakultet, 1997)
Gas chromatographic molecular retention indices for series of 20 synthesized N-methyl-N-substituded benzamides on DB-1, DB-5 and DB-WAX capillary columns isothermal at 170. 190 and 200 ⁰C were determined and the basis of ...
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 ...
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 ...
