Ispitivanje uticaja uljanog rastvarača na koncentraciju karotenoida u uljanim ekstraktima nevena
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2002)
Optical fibers with composite magnetic coating
(Elsevier, 2002)
The goal of these investigations was to define the process parameters that enable the formation of a composite coating with the most uniform thickness on an optical fiber. The composite coating was obtained by drawing the ...
Gas holdup in a gassed reciprocating plate column with Rashig rings placed in interplate spaces
(Canadian Society for Chemical Engineering, 2002)
The gas holdup is studies in a gassed reciprocating plate column with the addition of the Rashig rings placed in each interplate space. The gas holdup generally increases with increasing the vibration speed, the superficial ...
Chevron defect at the intersection of grain boundaries with free surfaces in Au
(American Physical Society, 2002)
We have identified a new defect at the intersection between grain boundaries and surfaces in Au using
atomic resolution transmission electron microscopy. At the junction line of 90
h110i tilt grain boundaries
of ...
Nekonvencionalne (nove) pređe

Hydrogen evolution reaction from EDTA solutions
(4th Conference of the Yugoslav Materials Research Society, 2002)
An attempt was made to investigate the mechanism and kinetics of hydrogen evolution reaction on zinc and platinum wire electrodes from solutions containing ethylene diamine tetraacetic acid (EDTA). EDTA is a tetra-basic ...
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 ...
Synthesis and structure of colloidal bimetallic nanocrystals: the non-alloying system Ag/Co
(American Chemical Society, 2002)
Monodisperse bimetallic Ag/Co composite nanocrystals have been prepared using colloid chemistry methods. Transmission electron microscopy showed well isolated Ag/Co particles centered around 12 nm in diameter. The composition ...
