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 ...
X-ray crystal structure of 10β-hydroxy-4β,5β-epoxyestr-1-en3,17-dione and antitumor activity of its congeners
(MDPI, 1999)
Based on the biological properties of epoxyquinols from natural sources, the title compound was synthesised as a potential antitumor agent. Its molecular structure was partially confirmed by NMR studies. The detailed ...
RuO2–TiO2 coated titanium anodes obtained by the sol–gel procedure and their electrochemical behaviour in the chlorine evolution reaction
(Elsevier, 1999)
TiO2 and RuO2 sols were obtained from RuCl3 and TiCl3 aqueous solutions by condensation and forced hydrolysis
at elevated temperature. The Ti supported coatings were obtained by the sol–gel method using a sol mixture in ...
Examination of the kinetics of Zr1.02Ni0.98 alloy hydriding / Ispitivanje reakcije hidriranja legure Zr1.02Ni0.98
(Belgrade : Serbian Chemical Society, 1999)
The hydriding kinetics of Zr1.02Ni0.98 alloy was examined in dependence on the number of hydriding/dehydriding cycles. The rate constants relating to three subsequent hydriding procedures of an alloy sample, at five ...
The effect of the pause-to-pulse ratio on the morphology of metal powder particles electrodeposited by square-wave pulsating overpotential
(Switzerland : Springer Nature, 1991)
It is well known that the deposition conditions such as
bath composition, hydrodynamic regime, temperature,
current density, exhibit a strong effect on the grain size
and the morphology of electrodeposited metal ...
Oxidative hydrolysis and acid-catalyzed rearrangement of steroidal isoxazolidines
(Elsevier, 1991)
Treatment of steroidal isoxazolidines 3a, 3b and 5b with N-methylhydroxylamine hydrochloride in boiling ethanol-pyridine (1:1) solution results in elimination of the CH3NH2fragment, affording products of oxidative hydrolysis ...
The roles of the ruthenium concentration profile, the stabilizing component and the substrate on the stability of oxide coatings
(Elsevier, 1992)
Electrocatalytic oxide coatings with variable concentration profiles of RuO2 as the active component were obtained through a combination of separately applied layers of RuO2, TiO2, IrO2, RuO2 + TiO2 and RuO2 + IrO2 on ...
The influence of OH- chemisorption on the catalytic properties of gold single crystal surfaces for oxygen reduction in alkaline solutions
(Elsevier, 1996)
Oxygen reduction on gold single crystal electrodes of various orientations, Au(hkl), in 0.1 M NaOH was studied by rotating disk electrode and rotating disk ring electrode techniques, with a goal to correlate the physical ...
The role of surface defects in HOPG on the electrochemical and physical deposition of Ag / Uloga površinskih defekata na HOPG-u u elektrohemijskoj I fizičkoj depoziciji Ag
(Belgrade : Serbian Chemical Society, 1999)
The role of defects on a substrate surface during the initial stages of nucleation and growth of Ag deposited electrochemically and physically on highly oriented pyrolytic graphite (HOPG) has been observed ex situ by ...
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 ...
