The determination of kinetics parameters of the hydrogen evolution on Ti-Ni alloys by ac impedance
(Pergamon-Elsevier Science Ltd, Oxford, 1997)
The kinetics and mechanism of hydrogen evolution at Ti-Ni alloys electrode has been studied by means of steady-state potentiostatic polarization and ac impedance spectrum measurements. Complex-plane spectrum plots are ...
Thermal investigations of some AlPO and MeAPO materials prepared in the presence of HF
(Elsevier, Amsterdam, 1997)
Hydrothermal synthesis of chabazite-like AlPO4 in a fluoride medium, using piperidine as the structure directing agent, is also successful in the preparation of transition-metal-modified AlPO products. The transition metal ...
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 ...
The Influence of Surfactants on Enzymatic Treatment of Wool
(Proc. XXVII Jornadas Del CED / XXVII CED Meeting on Surfactants, 1997)
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 ...
HREM observations of mechanical twinning in Cu-Ti alloys: Structure of incoherent and coherent twin interfaces
(Minerals, Metals & Materials Soc (TMS), 1997)
The flow of Cu-Ti alloys hardened by coherent β′ precipitates (Cu4Ti, D1a superstructure) is particularly interesting since these alloys show profuse twinning on multiple systems after small amounts of plastic flow by slip. ...
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, ...
Konformacije N-supstituisanih amida / Conformations of N-monosubstituted amides
(Beograd : Srpsko hemijsko društvo, 1997)
Synthesis and FTIR spectroscopic study of some N-monosubstituted propanamides
(Elsevier, Amsterdam, 1997)
In the present work we investigated the conformations of some N-mono-substituted propanamides of general formula CH3CH2CONHR, wherein R is chosen from n-(C-1-C-9)alkyl, cyclo(C-3-C-6)alkyl, some branched (C-3-C-6)alkyl or ...
The retention behavior of some anilides on unconventional TLC supports
(Akademiai Kiado Zrt, Budapest, 1997)
The TLC retention behavior of formanilide and I substituted acetanilides on starch and cellulose layers has been studied using aqueous mobile phases with methanol, acetonitrile, acetone, and 1-propanol as modifiers, R-Mw ...
