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 ...
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 ...
Dynamic behavior of the bray-liebhafsky oscillatory reaction controlled by sulfuric acid and temperature
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The non-periodic, periodic and chaotic regimes in the Bray-Liebhafsky (BL) oscillatory reaction observed in a continuously fed well stirred tank reactor (CSTR) under isothermal conditions at various inflow concentrations ...
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 ...
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 ...
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 ...
Yb3+ doped dyphillosilicates prepared by thermally induced phase transformation of zeolites
(Maik Nauka/Interperiodica/Springer, New York, 2007)
Yb3+-doped Ba and Sr diphyllosilicates (hexacelsians) have been synthesized using the Na form of LTA zeolite by ion-exchange procedure and thermal treatment. The crystal structures of both doped samples are refined and ...
