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 ...
The origin of high activity of Pt-Au surfaces in the formic acid oxidation
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
We have investigated the oxidation of HCOOH on Au-modified Pt (Au"Pt) and Pt-modified Au (Pt")/Au) electrodes to establish the role of the ensemble and the electronic effect in the catalysis of this reaction. The surfaces ...
The validity of the general similarity law for electrical breakdown of gases
(IOP Publishing Ltd, Bristol, 2006)
This paper investigates the validity of the similarity law in cases of dc and pulse breakdown of gases. Geometrically similar systems insulated with SF6 gas were used during experiments. It is shown that the similarity law ...
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 ...
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 ...
Production of bioethanol from corn meal hydrolyzates
(Elsevier Sci Ltd, Oxford, 2006)
The two-step enzymatic hydrolysis of corn meal by commercially available a-amylase and glucoamylase and further ethanol fermentation of the obtained hydrolyzates by Saccharomyces cerevisiae yeast was studied. The conditions ...
