Prediction of ductile fracture initiation using micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
In the paper ductile fracture initiation analysis of low-alloyed ferritic steel has been made by application of two micromechanical models: the Rice-Tracey void growth model and the Gurson-Tvergaard-Needleman (GTN) model. ...
Kinetics of the hydrogen evolution reaction on Fe-Mo film deposited on mild steel support in alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The mechanism and kinetics of the hydrogen evolution reaction were studied. in 1.0 mol dm(-3) NaOH solution on Fe-Mo alloy electrodes prepared by electrodeposition at constant current densities from a pyrophosphate bath. ...
Modeling of the substrate and product transfer coefficients for ethanol fermentation
(WILEY-VCH Verlag GmbH & Co., 2008)
The transfer phenomena of the substrate and product for ethanol fermentation with immobilized biocatalyst were investigated. Fermentation was carried out with a biocatalyst consisting of Ca-alginate gel in the form of ...
Mechanochemical synthesis of nanocrystalline titanium monoxide
(Elsevier, 2008)
Nanocrystalline cubic titanium monoxide, TiOx (0.92 < x < 1.19), with mean crystallite size of ≈ 6 nm, was synthesized by mechanochemical treatment of Ti and TiO2 (rutile) powder mixtures with molar ratios of 1:1, ...
The evolution of structure induced by intensive milling in the system 2Bi 2 O 3 · 3TiO 2
(Elsevier, 2006)
Concurrent mechanochemical treatment of either a stoichiometric 2Bi 2 O 3 · 3TiO 2 powder mixture or (pulverized) Bi 4 Ti 3 O 12 compound was performed in a planetary ball mill. Relevant structural parameters: crystallite ...
Microstructure of LaNiO3 thin films obtained by the spin-on technique from citrate precursors
(Elsevier Sci Ltd, Oxford, 2008)
The morphology of perovskite LaNiO3 (LNO) thin films is a very important feature considering the fact that they could be used as an electrode material in ferroelectric devices. In this work, LNO films were prepared from ...
Ultraviolet Protection Factor of Gray-state Plain Cotton Knitted Fabrics
(Sage Publications Ltd, London, 2009)
The protection provided by clothing against ultraviolet (UV) radiation has been the subject of considerable recent research. However, a lack of investigations concerned with the influence of yarn properties on UV protection ...
Occurrence and fate of emerging wastewater contaminants in Western Balkan Region
(Elsevier B.V., 2008)
This paper reports on a comprehensive reconnaissance of over seventy individual wastewater contaminants in the region of Western Balkan (WB; Bosnia and Herzegovina, Croatia and Serbia), including some prominent classes of ...
Modelling of ductile fracture initiation in strength mismatched welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
In this paper, the effect of strength mismatch and width of the welded joints oil the stress-strain distribution in the crack tip region has been discussed. The single-edge notched bend (SENB) specimens (precrack length ...
Morphologies of electrochemically formed copper powder particles and their dependence on the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2008)
Copper powder particles formed by electrolysis under different quantities of evolved hydrogen were analyzed using the scanning electron microscopy (SEM) technique. It was found that the structure of the powder particles ...
