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 ...
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 ...
Influence of most important radicals on the numerically simulated belousov-zhabotinsky oscillatory reaction under batch conditions
(Maik Nauka/Interperiodica/Springer, New York, 2011)
In the already proposed model of the Belousov-Zhabotinsky reaction with the Br(2)O species as intermediate one, the reactions with malonyl (MA(center dot)), bromomalonyl (BrMA(center dot)) and tartronyl (TA(center dot)) ...
Temperature influence on the malonic acid decomposition in the Belousov-Zhabotinsky reaction
(Maik Nauka/Interperiodica/Springer, New York, 2009)
The kinetic investigations of the malonic acid decomposition (8.00 x 10(-3) mol dm(-3) a parts per thousand currency sign [CH(2)(COOH)(2)](0) a parts per thousand currency sign 4.30 x 10(-2) mol dm(-3)) in the Belousov-Zhabotinsky ...
Monolayer gas adsorption in plasmonic sensors: Comparative analysis of kinetic models
(Maik Nauka/Interperiodica/Springer, New York, 2013)
The analysis of adsorption kinetics is given, assuming no dissociative adsorption takes place and no multiple binding sites exist. The phenomenological nonlinear model and the simple linear model are considered from the ...
Temperature dependence of catalytic cyclohexane partial oxidation in a polytetrafluoroethylene reactor
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Polymer-supported Co(II) catalyst was prepared and its activity and selectivity in the partial oxidation of cyclohexane was determined at several temperatures in a polytetrafluoroethylene reactor ( PTFE). The catalyst was ...
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 ...
Activity of polymer supported cobalt catalyst in the Bray-Liebhafsky oscillator
(Maik Nauka/Interperiodica/Springer, New York, 2009)
The infuence of poly-4-vinylpyridine-co-divinylbenzene-Co2+ catalyst on the Bray-Liebhafsky (BL) oscillator used as the matrix for establishing catalyst's activity was analyzed. The addition of the catalyst do not change ...
Large deviation spectra of chaotic time series from Bray-Liebhafsky reaction
(Maik Nauka/Interperiodica/Springer, New York, 2009)
We applied multifractal analysis on time series obtained by deterministic simulation of the Bray-Liebhafsky oscillatory reaction. Large deviation spectrum was used to represent multifractal properties of the attractor. We ...
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 ...
