Analysis of amphetamines illegally produced in Serbia / Analiza amfetamina ilegalno proizvedenog u Srbiji
(Serbian Chemical Society, Belgrade, 2008)
Forensic practice in the Republic of Serbia faced the illegal production of amphetamine for the first time in 2003. This paper presents the results of the chemical characterization of 32 batches of amphetamine samples from ...
Analysis of smart aramid fiber reinforced laminar thermoplastic composite material under static loading / Analiza SMART aramidnim vlaknom ojačanih laminarnih termoplastičnih kompozitnih materijala tokom statičkog opterećivanja: poređenje eksperimentalnih rezultata i numeričke simulacije
(Military Technical Institute, Belgrade, 2008)
In order to obtain a composite material with desired improved resistance to penetration of ballistic projectiles, a poly(p-phenyleneterephthalamide) reinforced laminar thermoplastic composite material has been made. This ...
Temperature dependence of the kinetics of oxygen reduction on carbon-supported pt nanoparticles / Temperaturna zavisnost elektrohemijske redukcije kiseonika na nanočesticama platine na ugljeničnom nosaču
(Serbian Chemical Society, Belgrade, 2008)
The temperature dependence of oxygen reduction reaction (ORR) was studied on highly dispersed Pt nanoparticles supported on a carbon cryo-gel. The specific surface area of the support was 517 m2 g-1, the Pt particles ...
Electrochemical and sorption characteristics of metacryloxypropyltrimethoxysilane coatings / Elektrohemijske i sorpcione karakteristike prevlaka metakriloksipropiltrimetoksisilana
(Engineering Society for Corrosion, Belgrade, Serbia, 2008)
The aim of this work was to investigate the influence of deposition parameters (silane solution concentration, deposition time, curing time) on electrochemical and sorption characteristics of metacryloxypropyltrimethoxysilane ...
Significance of cracks in the heat-affected-zone of steels for elevated temperature application / Značaj prslina u zoni uticaja toplote čelika za povišene temperature
(Society for Structural Integrity and Life, Institute for Material Testing, 2008)
Damage and failure of welded joints are classified according to the crack position. Type IV cracking occurs in welded joints in creep-resistant steels, due to enhanced rate of creep void formation in the presence of coarse ...
Hysteretic behavior modeling of elastoplastic materials / Modeliranje histerezisnog ponašanja elastoplastičnih materijala
(Serbian Society of Mechanics & Mathematical Institute of the Serbian Academy of Sciences and Arts, Belgrade, 2008)
In the present paper the Preisach model of hysteresis is applied to model cyclic behavior of elasto-plastic material. Rate of loading and viscous effects will not be considered. The problem of axial loading of rectangular ...
