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 ...
Microstructure-property relations for porous bismuth films
(IEEE, 1999)
Metallorganic decomposition of metal carboxylates is used to prepare porous thin films of bismuth. The general approach is to spin coat a precursor solution, bismuth 2-ethylhexanoate in a solvent of 2-methyl-1-propanol on ...
Heat-treated iron(III) tetramethoxyphenyl porphyrin supported on high-area carbon as an electrocatalyst for oxygen: I. Characterization of the electrocatalyst
(Electrochemical Soc Inc, Pennington, 1998)
Iron(III) tetramethoxyphenyl porphyrin chloride adsorbed on the Black Pearls carbon (FeTMPP-Cl/BP) was heat-treated at temperatures from 200 to 1000°C in Ar atmosphere and characterized by using cyclic voltammetry, X-ray ...
Cathodic processes on corroding low-carbon steel: the effect of the degree of deformation
(Pergamon-Elsevier Science Ltd, Oxford, 1992)
The influence of the degree of deformation of low-carbon steel (0.48% Mn, 0.47% Si, 0.085% C) caused by mono-axial stretching was investigated with respect to the kinetics of electrochemical hydrogen evolution and the ...

(Savez inženjera i tehničara tekstilaca Srbije, 1998)
Posle velike ekspanzije u 1994. god., svetska proizvodnja hemijskih vlakana (sintetizovanih, celuloznih) u 1996. god. zabeležila je porast sličan ranijim godinama. Svetska proizvodnja hemijskih vlakana u 1996.god. porasla ...
Proučavanje sorpcionih svojstava ugljeničnih vlaknastih sorbenata / Study of Sorption properties of Fibrous Carbon Sorbents
(Loznica : Viskoza, 1995)
Ugljenični vlaknasti sorbenti se odlikuju dobrom adsorpcijom gasova i para, kako u statičkim, tako i dinamičkim uslovima i koriste se kao filtracioni materijal. U ovom radu proučavana su sorpciona svojstva ugljeničnim ...
Oxygen reduction on iron-IV. The reduction of hydrogen peroxide as the intermediate in oxygen reduction reaction in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 1991)
The kinetics of hydrogen peroxide reduction were studied on iron in borate buffered and unbuffered solutions of pH ranging from 8.6 to 13.8, with and without the presence of chloride ions. A rotating disk electrode was ...
