Comparative electrochemical study of some cobalt(III) and cobalt(II) complexes with azamacrocyles and β-diketonato ligands / Komparativno elektrohemijsko ispitivanje nekih kobalt(III)i kobalt(II) kompleksa sa azamakrocikličnim i β-diketonato ligandima
(Serbian Chemical Society, 2003)
The electrochemical properties of eight mixed-ligand cobalt(III) and co balt(II) complexes of the general formulas [CoIII(Rac)cyclam (ClO4)2 (1)–(4) and [Co2II(Rac)tpmc](ClO4)3 (5)–(8) were studied. The substances were ...
Photopyropiezoelectric elastic bending method
(AIP Publishing, 2003)
A method of investigation of semiconductors and metal–semiconductor structures based on two techniques: The elastic bending technique and pyropiezoelectric (PPE) technique was presented. The method was demonstrated on a ...
Terrorism in the light of nonlinear sciences: Stoichiometric network analysis of the population processes / Terorizam u svetlu nelinearnih nauka - stehiometrijska mrežna analiza populacionih procesa
(Nauka, tehnika, bezbednost, 2003)
Terrorism is considered as a complex nonequilibrium dynamical system, and it is described with simple model. The model is tested by Stoichiometric Network Analysis. Stability/instability condition is determined. Dynamical ...
The influence of heat treatment and finishing on the mechanical and dielectric properties of glass fabric-epoxy resin laminar composites
(Springer Netherlands, 2003)
The aim of this investigation was to define the optimum conditions of obtaining glass fabric - epoxy resin laminar composites with mechanical and dielectric properties that satisfy the quality needed for production of ...
The effect of preparation of aluminum surface on the structure of final coating of nickel / Uticaj pripreme površine aluminijuma na strukturu završne prevlake nikla
(Belgrade, Serbia : Engineering Society for Corrosion, 2003)
In this work structure characteristics of the final coating of nickel were studied. Nickel was deposited onto chemically prepared aluminum, chemically and electrochemically. Structural characteristics of metallic coatings ...
The effect of the particle shape and structure on the flow ability of electrolytic copper powder II: The experimental verification of the model of the representative powder particle / Uticaj oblika i strukture čestica na tečljivost elektrolitičkog bakarnog praha II - eksperimentalna potvrda modela reprezentativne čestice praha
(Serbian Chemical Society, 2003)
An analysis of the effects of the shape, surface structure and size distribution of particles on the flow ability of the copper powder was performed. It is shown that the most important property of the particles of a powder, ...
Oxidative fragmentation of 5-hydroxy-1-oxo-5α-cholestan-3β-yl acetate / Oksidativne fragmentacije 5-hidroksi-1-okso-5α-holestan-3β-il-acetata
(Serbian Chemical Society, 2003)
5-hydroxy-1-oxo-5α-cholestan-3β-yl acetate (11) was prepared in 5 steps starting from (E)-3β-acetoxy-5,10-seco-1(10)-cholesten-5-one (6). Treatment of the 1-oxo-5-hydroxy derivative 11 with lead tetraacetate (LTA) (under ...
Ballistic magnetoresistance versus magnetostriction effects in electrodeposited nanocontacts at room temperature
(Institute of Electrical and Electronics Engineers, Inc., 2003)
The authors present experiments and discuss recent results on ballistic magnetotesistance in nanometer size (on the order of 1 to 10 nm) nanocontacts grown by electrodeposition in
thin wires and in thin films of a few ...
Oxidative Fragmentations of the 5-alpha and 5-beta-Hydroxy-B-norcholestan-3-beta-yl Acetates
(Wiley, 2003)
Oxidations of 5α‐hydroxy‐B‐norcholestan‐3β‐yl acetate (8) with Pb(OAc)4 under thermal or photolytic conditions or in the presence of iodine afforded only complex mixtures of compounds. However, the HgO/I2 version of the ...
The effects of nitric oxide (NO) and peroxynitrite on MnSOD (E.coli)
(Turkish Biochemical Society, 2003)
Our results demonstrate that MnSOD (E. coli)-stimulated generation of NO+ and NO- species is associated with nitration of enzyme tyrosine residues and dityrosinc formation, which cause enzyme inactivation. This represents ...
