Elimination of Nucleation Exclusion Zones by Electrodeposition at a Reversing Current / Eliminacija zona isključenja nukleacije taloženjem reversnom strujom
(Belgrade : Serbian Chemical Society, 1998)
Elimination of nucleation exclusion zones by electrodeposition at a reversing current (RC) in the seconds time range is considered. It is shown that nucleation exclusion zones formed in constant regimes can be eliminated ...
Kinetic and mechanistic study of methanol oxidation on a Pt(110) surface in alkaline media
(Elsevier, 1998)
The comparative study of methanol oxidation on a Pt(110) surface was carried out in bicarbonate, carbonate and sodium hydroxide solutions. It was shown that OH- electrosorption precedes the oxide layer formation in sodium ...
Kinetic and mechanistic study of methanol oxidation on a Pt 100/ surface in alkaline media
(Elsevier, 1998)
A comparative study of methanol oxidation on a Pt(100) surface was carried out in bicarbonate, carbonate and different pH values of sodium hydroxide solutions. It was shown that Pt(100) adsorbs OH and 'poisoning species'. ...
An efficient semisynthesis of 7-deoxypaclitaxel from taxine
(Royal Soc Chemistry, Cambridge, 1998)
Highly cytotoxic 7-deoxypaclitaxel analogues are obtained by a semisynthesis starting from taxine-the most abundant naturally occurring taxane diterpene fraction.
Mixed dopaminergic/serotonergic properties of several 2-substituted 4-[2-(5-benzimidazole)ethyl]-1-arylpiperazines
(Wiley-VCH Verlag, 1998)
A series of substituted 4-[2-(5-benzimidazole)ethyl]-arylpiperazines was synthesized by introducing different substituents into position 2 of benzimidazole ring of 4-[2-(N,N-di-n-propylamino)ethyl]-1,2-diaminobenzenes. ...
Electrochemical passivation of iron in NO3-, SO42-, and ClO4- solutions
(American Chemical Society (ACS), 1998)
Electrochemical passivation of iron was studied in NO3-, SO42-, and ClO4- solutions of different pH values. Passivation potential of iron in NO3- and ClO4- was similar for any pH examined, while in SO42- it was more anodic. ...
Modeling of drawing thin glass sheet from a preform / Model izvlačenja tankih staklenih traka iz predoblika
(Serbian Chemical Society, 1998)
A one-dimensional model of thin glass sheet drawing has been developed. This model includes momentum, heat and mass balance equations. The density, viscosity and specific heat of the glass were calculated as functions of ...
The Determination of the Optimum Current Wave in Reversing Current Metal Electrodeposition / Određivanje optimalnog odnosa talasa reversne struje pri elektrohemijskom taloženju metala
(Belgrade : Serbian Chemical Society, 1998)
The experimental procedure for the determination of the optimum reversing current wave, producing uniformlly distributed polycrystalline deposits, is given. First, deposition at the maximum current density for different ...
Preliminary investigation of antimicrobial activity of St. John's Wort
(Medical University Faculty of Pharmacia, 1998)
Preliminary investigations of Hypericum perforatum have shown that one of the most important activities of the plant is its antibacterial activity. The most active component of the acetonic extract has been isolated through ...
New substituted 2-methylthiomethyl- and 2-methylsulphinylmethylenebenz- imidazoles with D 2 /5-HT(1A) activity
(Govi-Verlag Pharmazeutischer Verlag GmbH, 1998)
Several 2-methylthiomethylbenzimidazoles (3a-e) and the corresponding sulphinyl derivatives 4a-e were synthesized and evaluated measuring their in vitro binding affinity at the D 1 and D 2 dopamine (source: synaptosomal ...
