The state of nickel in the silver modified NiMg/SiO2 vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Two series of silver modified Ni-Mg materials were synthesized by precipitation-deposition on SiO2 support derived from two silica sources: diatomite activated at 800°C (Series a; Mg/Ni = 0.1 and SiO 2/Ni = 1.07) and ...
A study of the dispersity of iron oxide and iron oxide-noble metal (Me=Pd, Pt) supported systems
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Samples of one-(Fe) and two-component (Fe-Pd and Fe-Pt) catalysts were prepared by incipient wetness impregnation of four different supports: TiO2 (anatase), gamma-Al2O3, activated carbon, and diatomite. The chosen synthesis ...
Porous glycidyl methacrylate-bentonite composite
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Crosslinked macroporous copolymer of glycidyl methacrylate and ethylene glycol dimethacrylate (CP) and copolymer composite with acid modified clay (CP-S-A) were prepared by radical suspension copolymerization and functionalized ...
Mass transfer and fluid flow visualization in packed and fluidized beds by the adsorption method
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Mass transfer coefficient (j D ) between fluid and column wall in liquid packed and fluidized beds of spherical inert particle has been studied experimentally using adsorption method. Experiments were conducted in column ...
Modification of dense TiO2 particles using polyethylene glycol template: Synthesis, characterization, and photocatalytic activity
(Maik Nauka/Interperiodica/Springer, New York, 2015)
In this study, an effort has been made to prepare TiO2 materials by sol-gel technique using polyethylene glycol (PEG) as pore directing agent. Different PEG amounts were used during samples preparation in order to investigate ...
Electrochemical behavior of 5-substituted 2-alkylidene-4-oxothiazolidine derivatives studied by cyclic voltammetry
(Maik Nauka/Interperiodica/Springer, New York, 2007)
This study demonstrates the electrochemical activity of selected 2-alkylidene-4-oxothiazolidine compounds containing different substituents at the C5-position on the Pt-electrode in 0.1 M TBAHFP + MeCN in the potential ...
Perlite as a potential support for nickel catalyst in the process of sunflower oil hydrogenation
(Maik Nauka/Interperiodica/Springer, New York, 2015)
Investigation was conducted in order to elucidate the possibility of using perlite as support for preparation of nickel based precursor catalyst, potentially applicable in vegetable oil hydrogenation process. On three ...
Enhanced activity in ethanol oxidation of Pt3Sn electrocatalysts synthesized by microwave irradiation
(Maik Nauka/Interperiodica/Springer, New York, 2011)
High surface area carbon supported Pt and Pt3Sn catalysts were synthesized by microwave irradiation and investigated in the ethanol electro-oxidation reaction. The catalysts were obtained using a modified polyol method in ...
The stability of the extended model of hypothalamic-pituitary-adrenal axis examined by stoichiometric network analysis
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Stoichiometric network analysis (SNA) represents a powerful mathematical tool for stability analysis of complex stoichiometric networks. Recently, the important improvement of the method has been made, according to which ...
Methanol electrooxidation in alkaline solutions on platinum-based electrodes: Classical and dynamical approach
(Maik Nauka/Interperiodica/Springer, New York, 2013)
The electrochemical oxidation of methanol has been carefully studied due to its application in fuel cells. In this work electrooxidation of methanol was investigated on bare platinum electrode, the platinum electrode covered ...
