NaY zeolite: A useful catalyst for nitrile hydrolysis
(Molecular Diversity Preservation International, Basel, 2000)
The NaY zeolite catalysed hydrolysis of nitriles to primary amides is reported. It is found that aryl nitriles with strong electron-withdrawing substituents and cyanopyridines are readily hydrolysed in the water suspension, ...

A new current line division concept for the determination of the current distribution in electrochemical cells. Part I. Theoretical background of the corner weakness effect in electroforming / Нов концепт поделе струјних линија за одржавање расподеле струје у електрохемијским ћелијама. Део I.Теоријске основе појаве "Corner weakness" у галванопластици
(Belgrade : Serbian Chemical Society, 2000)
A new approach to the determination of the current distribution in electrochemical
cells, the current line division concept, is introduced. The new concept, based on the
basic equations of electrics and electrochemical ...
Isomerization and selectivity calculation of the soybean oil hydrogenation process / Izomerizacija i izračunavanje selektivnosti u procesu hidrogenacije sojinog ulja
(Faculty of Technology, Novi Sad, 2000)
Soybean-oil hydrogenation process has been conducted in an industrial reactor by synthesized NICAT-2000 catalyst and by commercial G-70 catalyst under the same working conditions. Although this reaction includes a series ...
The Schottky barrier contribution to photoacoustic effect in Au-Si system
(IEEE Computer Society, 2000)
The photoacoustic effect in metal-semiconductor system, i.e., the influence of Schottky barrier on the thermal and electronic transport processes in semiconductor was investigated. The amplitude and phase spectra were ...
Investigation of ion-beam modified silicon by photoacoustic method
(IEEE Computer Society, 2000)
Thermal, elastic and electronic transport properties of ion-modified silicon samples were investigated by a photoacoustic frequency transmission technique. The experimental photoacoustic data vs the modulating frequency ...

Electroreduction of cefetamet on mercury, platinum and gold electrodes / Elektroredukcija cefetameta na elektrodama od žive, platine i zlata
(Serbian Chemical Society, 2000)
The electroreduction of cefetamet (CEF) using gold and platinum electrodes has been investigated in slightly alkaline medium (pH 8.40) where adsorption, previously observed at mercury electrode, was pronounced. This ...
Volatile constituents of Achillea serbica Nym.
(John Wiley and Sons Ltd, 2000)
The volatile constituents of Achillea serbica Nym. (Asteraceae), an endemic plant of the Balkan Peninsula, has been analysed using GC and CC-MS. Fifteen identified components constituted 95.7% of the oil. The major fractions ...
