Influence of ionic equilibrium in the CuSO(4)-H(2)SO(4)-H(2)O system on the formation of irregular electrodeposits of copper
(Oxford : Pergamon-Elsevier Science Ltd, 2008)
The relative concentration of hydrogen ion (H(+)) as a function of sulfuric acid (H(2)SO(4)) concentration (calculated using Pitzer's model) and the electrochemical processes by which irregular copper deposits are formed ...
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, ...
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 ...
Chitosan contribution on wool treatments with enzyme
(Elsevier Ltd., 2008)
In a previous research work, it was observed that the application of biopolymer chitosan (CHT) on wool fabrics before the enzymatic treatment promotes an increase of the weight loss. In order to deep on the role played by ...
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 ...
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 ...
Kinetics and sintering mechanisms of hydro-thermally obtained hydroxyapatite
(Elsevier, 2008)
In this paper, the kinetics and sintering mechanism of hydro-thermally synthesized hydroxyapatite in the temperature range 900-1100 degrees C are presented. It was found that at 900 degrees C, the sintering process is very ...
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 ...
Characterization and quantitative analysis of surfactants in textile wastewater by liquid chromatography/quadrupole-time-of-flight mass spectrometry
(Wiley, Hoboken, 2008)
A method based on the application of ultra-performance liquid chromatography (UPLC) coupled to hybrid quadrupole-time-of-flight mass spectrometry (QqTOF-MS) with an electrospray (ESI) interface has been developed for the ...
