Thermomechanical processing of micro alloyed steels in Sartid A.D.: Part III - comparison of of Tnr temperatures determined on laboratory and industrial scale / Termomehanička prerada mikrolegiranih čelika koncerna Sartid: III deo - poređenje Tnr temperatura određenih u laboratorijskim i industrijskim uslovima
(Savez inženjera metalurgije Srbije, Beograd, 2002)
The aim of this work was to compare the Tnr temperatures of microalloyed steels estimated on laboratory (Tnr**l) and industrial scale (Tnr**l). Laboratory and industrial scale are related to testing on high temperature ...
Methanol electrooxidation on supported Pt and PtRu catalysts in acid and alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2002)
The kinetics of methanol oxidation on supported 47.5 wt.% Pt and 54 wt.% Pt-Ru (with nominal Pt:Ru ratios of 2:3) catalysts are measured in 0.5 M H2SO4 and 0.1 NaOH at 295 and 333 K using thin-film rotating disk electrode ...
Synthetic lubricants based on copolymers of n-butyl methacrylate and α-olefins / Sintetička maziva na bazi kopolimeran-butilmetakrilata i α-olefina
(Association of Chemical Engineers of Serbia, 2002)
Synthetic fluids obtained by the copolymerization of α -olefins with alkyl esters of unsaturated carboxylic acids have a unique combination of properties of non-polar poly-a-olefins (PAOs) and polar esters in a single ...
Interface shape and distribution of solute during Vertical Bridgman growth of Al-Cu alloy
(Elsevier, Amsterdam, 2002)
Results presented in this paper contribute to investigation of the influence of solidification rate (R) and the initial concentration of solute (C-o) on the interface shape and the distribution of the solute. Solidification ...
The thermal degradation of Poly(methyl methacrylate)/silicon carbide nanocomposites / Termička degradacija nanokompozita poli(metil metakrilat)/silicijum-karbid
(Association of Chemical Engineers of Serbia, 2002)
The thermal stability of poly(methyl methacrylate) (PMMA) and silicon carbide (SiC) composites was studied by thermogravimetry. The influence of particle size, SiC structural modification and particle specific surface was ...
Dependence of the solid-liquid interface structure on the solidification process parameters / Zavisnost strukture granice faza tečno-čvrsto od parametara procesa očvršćavanja
(Savez inženjera metalurgije Srbije, Beograd, 2002)
Influence of the solidification rate, temperature gradient and initial concentration of the solute on the interface shape was investigated during solidification from the melt. The dependence of the microstructure on the ...
Alumina/silica aerogel with zinc chloride alkylation catalyst: Influence of supercritical drying conditions and aerogel structure on alkylation catalytic activity
(Elsevier, Amsterdam, 2002)
Alumina/silica aerogel with zinc chloride alkylation catalyst, was obtained using one step sol-gel synthesis and subsequent drying with the supercritical carbon dioxide. The high density supercritical carbon dioxide drying ...
Influence of the semiconductor doping level on the carrier surface density in an AlGaN/GaN MODFET channel
(Proceedings of the fourth Yugoslav Materials Research Society Conference (YUCOMAT IV), 2002)
In this paper the influence of doping level in AlGaN and GaN on the carriers surface density in a channel of modulation doped field effect transistors (MODFETs) has been investigated. The carriers concentration profile in ...
Normal- and reversed-phase chromatography of para-substituted propanoic acid Amides
(Springer Heidelberg, Heidelberg, 2002)
The chromatographic behavior of newly synthesized para-substituted propanoic acid amides has been studied in normal- and reversed-phase thin-layer chromatography. The retention mechanism on different TLC supports was ...
Stress corrosion cracking susceptibility of Al-Mg alloy sheet with high Mg content
(Elsevier Science Sa, Lausanne, 2002)
Slow strain rate testing (SSRT) was used to study the effect of the microstructure on the stress corrosion cracking (SCC) susceptibility of Al-Mg alloy sheet containing 6.8 wt.% Mg. In the cold-rolled and fully annealed ...
