Reversal of substituent effect on electronic absorption spectra of N-(4-substituted phenyl)-benzamides in different solvents
(Natl Inst Science Communication, New Delhi, 2002)
Absorption spectra of eleven N-(4-substituted phenyl)-benzamides have been recorded in ten solvents in the range 200400 nm. The substituents at the phenyl nucleus are as follows: N (CH3)(2), OCH3, CH3, H, Cl, Br, F, CN, ...
The mechanism of cathodic electrodeposition of epoxy coatings and the corrosion behaviour of the electrodeposited coatings / Mehanizam kataforetskog taloženja epoksidnih prevlaka i koroziono ponašanje dobijenih prevlaka
(Serbian Chemical Society, Belgrade, 2002)
The model of organic film growth on a cathode during electrodeposition process proposes the current density-time and film thickness-time relationships and enables the evaluation of the rate contents for the electrochemical ...
Glass-ceramic enamels derived from the Li2O-Na2O-Al2O3-TiO2-SiO2 system / Staklo-keramički emajli izvedeni iz sistema Li2O-Na2O-Al2O3-TiO2-SiO2
(Serbian Chemical Society, Belgrade, 2002)
The results of research on the conditions for obtaining model glass-ceramic enamels, derived from the basic Li2O-Na2O-Al2O3-TiO2-SiO2 system, by varying the initial composition and thermal treatment conditions, are presented ...
The estimation of solid copper surface tension in copper sulfate solutions
(Journal of the Serbian Chemical Society, 2002)
In metal electrodeposition in the limiting diffusion current density range, the deposition current density remains constant regardless of the deposition overpotential used, At the same time, die larger the deposition ...
Analysis of the transferability of micromechanical parameters of damage of steel under the conditions of ductile-fracture initiation
(Springer, New York, 2002)
For the description of the mechanical behavior of a cracked material, we use a macromechanical model of fracture based on the well-known criterion of plastic yield for porous materials. This model is realized as a computational ...
Indene dimerization products / Proizvodi dimerizacije indena
(Serbian Chemical Society, Belgrade, 2002)
The reaction of 1H-indene (indene) in the presence of Friedel-Crafts acids was studied. As expected [M. Spiteller, J. Jovanović, Fuel 78(1999)1263] there were dimers and trimers in the product mixture together with higher ...
The representative particle of copper powder and branch of copper dendrites / Reprezentativna čestica bakarnog praha i grananje dendrita bakra
(Serbian Chemical Society, 2002)
Electrochemically deposited copper powders, which are formed of particles of different size and morphology, are characterized by some properties like specific surface and apparent density. Aprocedure of the determination ...
The current distribution in an electrochemical cell. Part VII. Concuding remarks
(Serbian Chemical Society, 2002)
A new method for the determination of the ability of an electrolyte to distrubute uniformly current density in an electrochemical cell is proposed. It is based on the comparison of the current in cells in which the electrode ...
Reflection and structural characteristics of semi-bright and mirror bright nickel coatings
(Journal of the Serbian Chemical Society, 2002)
The reflection and structural characteristics of the nickel coatings obtained in the presence of a basic brightening addition agent only, and of both a basic and top brightening, addition agent arc examined. It is shown ...
The effect of reversing current deposition on the apparent density of electrolytic copper powder / Uticaj reversne struje na nasipnu masu pri elektrolitičkom taloženju bakarnog praha
(Serbian Chemical Society, 2002)
The possibility of depositing copper powders with different apparent density by changing the shape of reversing current wave is shown. The morphology and crystallinity of powder particles can be varied considerably by ...
