Surface diffusion of clusters and thin film growth
(Elsevier, 1995)
An analogy between the behavior of real gases and the behavior of clusters deposited on a surface has been established. A relation similar to the Van der Waals equation was used, with the variables corresponding to the ...
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 ...
Substitued (E)-β-(benzoyl)acrylic acids suppressed survival of neoplastic human HeLa cells / Umanjeno preživljavanje neoplastičkih humanih HeLa ćelija supstituisanim (E)-b-(benzoil) akrilnim kiselinama
(Belgrade : Serbian Chemical Society, 1999)
The bacteriostatic activity of some of alkyl substituted (E)-β-(benzoyl)acrylic acids was shown earlier. The aim of this study was to investigate the antiproliferative action of 19 alkyl-, or halogeno-, or methoxy-, or ...
Synthesis and evaluation of several cathechol bioisosteres as potential dopamine receptor ligands
(Elsevier, 1991)
Derivatives of benzimidazole (I), benzimidazolone (II), benzimidazolethione (III), 2,3-dihydroxyquinoxaline (IV) and the noncyclic acetamide (V) and t rifluoroacetamide (VI) of the corresponding 1,2-pheny-lenediamiane were ...
Structural effects in electrocatalysis: oxygen reduction on platinum low index single-crystal surfaces in perchloric acid solutions
(Elsevier, 1994)
Oxygen reduction has been studied in 0.1 M HClO4 on the platinum low index surfaces, employing a hanging meniscus rotating-disk technique. A special cleaning procedure has been developed to remove impurities from the surface ...
The electrocatalytic properties of the oxides of noble metals in the electro-oxidation of some organic molecules
(Elsevier, 1997)
The electro-oxidation of organic compounds on gold and silver electrodes can occur either in a potential range more negative than that where the metal oxides are formed or within the more positive range where the surface ...
Application of glassy carbon substrated cyanide‐sensitive electrodes in determination of cyanide and mercaptan levels of wastewater
(Wiley, 1993)
Quantities of free and complex cyanides and mercaptans were determined in wastewater. Levels of free and complex cyanides were determined after previous oxidation of mercaptans by hydrogen peroxide. The procedure used for ...
The initiation of dendritic growth of electrodeposited copper on a rotating disc electrode with changing copper concentration and diffusion layer thickness
(Elsevier, 1992)
It is shown that the critical overpotential of dendritic growth initiation increases with increasing copper concentration under identical hydrodynamic conditions, as well as with increasing rotation speed to the rde (rotating ...
Substituent efects on the carbon-13 chemical shifts in α-phenylpyridylacrylic acids
(Elsevier Science Publishers B.V., 1992)
The 13C N.M.R. spectra of some substituted α-phenylpyridylacrylic acids, α-phenyl, α-(3-pyrydyl) and α-(3-pyrydyl-N-oxide) cinnamic acids were determined in deuterated dimethyl sulfoxide (d6-DMSO). It has been shown that ...
Demineralization of an oil shale by Bacillus circulans (“siliceous bacteria”)
(Elsevier, 1990)
Experiments are presented aimed at removing the silicates from an oil shale by a chemoorganoheterotrophic bacterium, Bacillus circulans. This process was expected to substitute the drastic HF-treatment in the kerogen ...
