Nb-doped TiO2 as a support of Pt and Pt-Ru anode catalyst for PEMFCs
(Elsevier Science Sa, Lausanne, 2010)
TiO2 doped by 0.5% Nb was synthesized by the acid-catalyzed sol-gel method. BET surface area was determined to be 72 m(2) g(-1). XRD measurements showed that TiO2 has structure of anatase with similar to 13 nm average ...
Behaviour of non-standard composition copper bearing anodes from the copper refining process
(Elsevier Science Bv, Amsterdam, 2010)
This paper addresses on investigation the possibility of electrolytic treatment the sulphur acidic waste solution, obtained in the conventional electrolytic copper refining process. Beside the high copper concentration, ...
Fabrication and characterization of HA-ZrO2-MWCNT ceramic composites
(Sage Publications Ltd, London, 2010)
In this article, a new kind of hydroxyapatite-zirconia-carbon nanotube (HA-ZrO2-MWCNT) ceramic composites was fabricated to enhance the mechanical properties of a hydroxyapatite (HA) ceramic for satisfying various requirements ...
The response of peritoneal macrophages to dapsone covalently attached on the surface of carbon nanotubes
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
Dapsone is an anti-microbial and anti-inflammatory drug. Water-dispersible dapsone-modified multi-wall carbon nanotubes (dap-MWCNTs) were prepared by chemical modification of the carboxyl groups introduced on the surface ...
Phase transition at subcritical and supercritical conditions of triglycerides methanolysis
(Elsevier, Amsterdam, 2010)
The analysis of phase equilibrium between methanol and glycerides during methyl esters of fatty acids (FAME or biodiesel) synthesis at high pressure and temperature is very important for describing the kinetic and process ...
Optimization Approach for Continuous Catalytic Regenerative Reformer Processes
(Amer Chemical Soc, Washington, 2010)
The new approach for simulation and optimization of a continuous catalytic regenerative (CCR) reformer process is proposed. Typical CCR reforming processes consist of three to four reactors with recycle. The reaction ...
Fast evaluation of periodic operation of a heterogeneous reactor based on nonlinear frequency response analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The concept of higher-order frequency response functions (FRFs), which is based on Volterra series representation of nonlineral systems, is used to analyse the time-average performance of a perfectly mixed reactor subject ...
Microstructural investigations of the simulated heat affected zone of the creep resistant steel P91
(Taylor & Francis Ltd, Abingdon, 2010)
The microstructural changes in the heat affected zone (HAZ) of 9% chromium ferritic steel for manufacturing fossil fired power plant components are investigated. The heat treatment region of 925 degrees C in HAZ was tested ...
Effects of Filler Content on Mechanical Properties of Macroporous Composites
(Vsp Bv, Leiden, 2010)
The mechanical properties of hydroxyapatite related macroporous biocomposites (MPBs) are influenced by a number of factors, such as the pore size, the filler content and the properties of the matrix and the inclusion. ...
1-Butanol + hexylamine plus n-heptane at temperature range (288.15-323.15 K): Experimental density data, excess molar volumes determination and modeling with cubic EOS
(Elsevier Science Bv, Amsterdam, 2010)
Densities rho of the ternary system 1-butanol + hexylamine + n-heptane and binaries: 1-butanol + hexylamine and hexylamine + n-heptane within the temperature range (288.15-323.15K) and atmospheric pressure are reported. ...
