Micromechanical modelling of fracture toughness in overaged 7000 alloy forgings
(Elsevier, 2006)
In this article, a multiple micromechanisms-based model that quantitatively relates the plane-strain fracture toughness, KIC, of overaged 7000 alloy forgings to their microstructural attributes, fracture surface morphology ...
Laboratory authorization versus accreditation in transitional economies: Case study of Serbia
(Springer New York, 2006)
Many CEE governments are still using various systems of laboratory authorization together with ISO/IEC 17025 laboratory accreditation. It is difficult to understand from the EU prospective, the existence of two parallel ...
Microstructure and pitting corrosion resistance of annealed duplex stainless steel
(Elsevier Ltd, 2006)
The transition from metastable to stable pitting was studied in 0.5 M NaCl water solution for two cast duplex stainless steels under different microstructural conditions achieved by annealing in the range from 900 °C to ...
Magneli phase titanium oxides as catalyst support - Electrochemical behavior of Ebonex/Pt catalysts
(Journal of New Materials for Electrochemical Systems, 2006)
The impregnation method has been applied to synthesize platinum nanoparticles on Magneli phase titanium oxide powder (Ebonex). Surface area of the Ebonex support was determined by BET technique. Distribution and morphology ...
Morphologies of copper deposits obtained by the electrodeposition at high overpotentials
(Elsevier, 2006)
Morphologies of copper deposits obtained at overpotentials belonging to the plateau of the limiting diffusion current density and at higheroverpotentials were examined by the scanning electron microscopy (SEM) technique. ...
Carbon cryogel as support of platinum nano-sized electrocatalyst for the hydrogen oxidation reaction
(Electrochimica Acta, 2006)
The kinetics of hydrogen oxidation reaction was studied in perchloric acid solution on carbon-supported Pt nanoparticles using the rotating disk electrode technique. Carbon cryogel and commercial carbon black. Vulcan XC-72 ...
Synthesis, structure and properties of thermoplastic poly(ester-siloxane) elastomers
(Serbian Chemical Society, 2006)
Two series of thermoplastic poly(ester-siloxane) elastomers (TPES), with hard segments based on poly(butylene terephthalate) (PBT) and soft segments based on poly(dimethylsiloxane) (PDMS), were synthesized by high-temperature, ...
Methanol oxidation at platinum electrodes in acid solution: Comparison between model and real catalysts / Oksidacija metanola na platinskim elektrodama u kiseloj sredini - poređenje model i realnih katalizatora
(Serbian Chemical Society, Belgrade, 2006)
Methanol oxidation in acid solution was studied at platinum single crystals, Pt(hkl), as the model catalyst, and at nanostructural platinum supported on high surface area carbon, Pt/C, as the real catalyst. The linear ...
Catalytic incineration of ethylene oxide in the packed bed reactor
(Elsevier, 2006)
Investigations of catalytic incineration of ethylene oxide (ETO) over Pt/Al2O3 catalyst have been conducted on laboratory and pilot scale level. The measurements of the reaction rate conducted under gradientless conditions ...
Complex estimation of bending elasticity of hemp woven fabric after washing treatment
(Emerald Group Publishing Limited, Bradford, 2006)
Purpose - This paper aims to investigate the elasticity of hemp woven fabric under action of bending force, before and after washing treatment. Design/methodology/approach - Bending elasticity was monitored in three different ...
