Nb-TiO2 supported platinum nanocatalyst for oxygen reduction reaction in alkaline solutions
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Platinum based nanocatalyst at home made Nb-TiO2 support was synthesized and characterized as the catalyst for oxygen reduction reaction in 0.1 mol dm(-3) NaOH, at 25 degrees C. Nb doped TiO2 catalyst support, containing ...
Simple and cost-effective measures for the improvement of paper mill effluent treatment - A case study
(Journal of Cleaner Production, 2011)
In this study, the performance and the efficiency of physico-chemical effluent treatment in a paper mill was investigated, with the aim of evaluating the treatment rationality and running stability. The effluent treatment ...
Non-noble metal composite cathodes for hydrogen evolution. Part II: The Ni-MoO2 coatings electrodeposited from nickel chloride-ammonium chloride bath containing MoO2 powder particles
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
In this work the procedure of the deposition of composite Ni-MoO2 coatings onto Ni mesh from the nickel chloride-ammonium chloride electrolyte containing suspended MoO2 powder particles, under simulated industrial deposition ...
Optimization of electrolytic process of formation of open and porous copper electrodes by the pulsating current (PC) regime
(Elsevier Science Sa, Lausanne, 2011)
Optimization of process of formation of open and porous copper electrodes, denoted as the honeycomb-like ones, by the regime of pulsating current (PC) is considered. The square-waves PC were consisted of the same amplitude ...
Platinum deposition from hydrogen-ion beam irradiated solid precursor
(Materials Letters, 2011)
We report a particular method of Pt/glassy carbon (GC) surface formation, based on a 15 key H(+/-) ion beam irradiation of thin H(2)PtCl(6)xnH(2)O layer placed over the GC surface. Hydrogen-ion beam irradiation provided ...
Synthesis and characterization of monetite and hydroxyapatite whiskers obtained by a hydrothermal method
(Elsevier Sci Ltd, Oxford, 2011)
High temperature hydrothermal syntheses, using calcium nitrate tetrahydrate, sodium dihydrogen phosphate and urea as precursors, and characterization of hydroxyapatite (HAp) whiskers are reported herein. The morphology and ...
Structural characterization of self-assembled ZnO nanoparticles obtained by the sol-gel method from Zn(CH3COO)(2)center dot 2H(2)O
(IOP Publishing Ltd, Bristol, 2011)
Zinc oxide nanopowders were synthesized by the sol-gel method from an ethanol solution of zinc acetate dihydrate. Detailed structural and microstructural investigations were carried out using x-ray diffraction, Raman ...
Bucket wheel excavator Integrity assessment of the bucket wheel boom tie-rod welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The bucket wheel boom tie-rods are vital structural parts of the bucket wheel excavators (BWE) Their failures inevitably cause BWE collapse and are followed among other things by a substantial financial loss (millions of ...
Ethylenediamine-modified multiwall carbon nanotubes as a Pt catalyst support
(Elsevier Science Sa, Lausanne, 2011)
Multi-walled carbon nanotubes (MWCNTs) were used as a support for Pt nanoparticles prepared by the microwave-assisted polyol method. The MWCNTs were pretreated by chemical oxidation (o-MWCNTs) followed by modification by ...
Isopiestic determination of the osmotic and activity coefficients of the {yKCl + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
The osmotic coefficients of aqueous mixtures of KCl and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method over the range of ionic strengths from (2.3700 to 11.250) mol . kg(-1) ...
