Synthesis and characterization of MoOx-Pt/C and TiOx-Pt/C nano-catalysts for oxygen reduction
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The oxygen reduction reaction (ORR) was studied at carbon supported MoOx-Pt/C and TiOx-Pt nanocatalysts in 0.5 mol dm(-3) HClO4 solution, at 25 degrees C. The MoOx-Pt/C and TiOx-Pt/C catalysts were prepared by the polyole ...
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, ...
Mechanochemically induced amorphous/crystalline phase transition in the Bi4Ti3O12 compound
(Elsevier, 2009)
Concurrent milling of Bi4Ti3O12 was carried out in a planetary ball mill with hardened-steel 13 or 6 mm diameter balls with a goal to investigate how the system responds to the constrains imposed by milling. Milling intensity ...
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 ...
Manganese leaching in the FeS2-MnO2-O2-H2O system at high temperature in an autoclave
(Elsevier Science Publishers B.V., 2000)
The paper shows: (a) the results of pyrite oxidation by gaseous oxygen in water suspension at high temperatures in an autoclave and (b) the results of simultaneous leaching of Mn4+ from pyrolusite ore by H2SO4 and FeSO4, ...
Prediction of the choking velocity and voidage in vertical pneumatic conveying of coarse particles
(Elsevier, 2006)
A method for predicting the choking velocity and voidage in vertical pneumatic conveying of coarse particles is developed and verified using the data obtained in this study as well as the data of Capes and Nakamura [C.E. ...
High activity of Pt4Mo alloy for the electrochemical oxidation of formic acid
(Amer Chemical Soc, Washington, 2007)
Surface processes on Pt4Mo alloy well-defined by X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) were studied in acid solution by cyclic voltammetry. It was established that Mo in the alloy is much more ...
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 ...
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 ...
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 ...
