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 ...
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 ...
Modelling of the Hypothalamic-Pituitary-Adrenal Axis Perturbations by Externally Induced Cholesterol Pulses of Finite Duration and with Asymmetrically Distributed Concentration Profile
(Maik Nauka/Interperiodica/Springer, New York, 2017)
A model was developed that can be used to study the effect of gradual cholesterol intake by food on the HPA axis dynamics. Namely, well defined oscillatory dynamics of vital neuroendocrine hypothalamic-pituitary-adrenal ...
Effect of the support and the reduction temperature on the formation of metallic nickel phase in Ni/silica gel precursors of vegetable oil hydrogenation catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Ni/SiO(2) materials with identical composition (SiO(2)/Ni = 1.0) have been synthesized by precipitation of Ni(NO(3))(2) center dot 6H(2)O solution with Na(2)CO(3) solution on the silica gel, obtained at three different pH ...
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 ...
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 ...
Numerical evidence of complex nonlinear phenomena of the Belousov-Zhabotinsky oscillatory reaction under batch conditions
(Maik Nauka/Interperiodica/Springer, New York, 2013)
By numerical calculations based on our previously proposed model with Br2O intermediate species we were able to simulate complex evolution of the Belousov-Zhabotinsky (BZ) reaction under batch conditions. In the defined ...
Mixed-mode oscillations and chaos in return maps of an oscillatory chemical reaction
(Maik Nauka/Interperiodica/Springer, New York, 2015)
The return maps, as an element of mathematical phenomenology appropriate for general examinations of complex dynamic states of the oscillatory systems were used to detect and explain the evolution of mixed-mode oscillations ...
Intermittent Chaos in the Bray-Liebhafsky Oscillator. Dependence of Dynamic States on the Iodate Concentration
(Maik Nauka/Interperiodica/Springer, New York, 2017)
Chaotic dynamic states with intermittent oscillations were generated in a Bray-Liebhafsky (BL) oscillatory reaction in an isothermal open reactor i.e., in the continuously-fed well-stirred tank reactor (CSTR) when the ...
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 ...
