Thermodynamics of the adsorption of different dyes onto bentonite modified with hexadecyltrimethylammonium cation
(Maik Nauka/Interperiodica/Springer, New York, 2013)
Removal of two different dyes: Acid Orange 10 (AO10) and Reactive Black 5 (RB5) from their aqueous solutions using organobentonite as adsorbent was investigated. The experiments were carried out at different temperatures ...
Thermal properties of poly(urethane-ester-siloxane)s based on hyperbranched polyester
(Maik Nauka/Interperiodica/Springer, New York, 2011)
Novel polyurethanes (PUs) were synthesized using hydroxy-terminated hyperbranched polyester (BH-20) and 4,4'-methylenediphenyl diisocyanate (MDI) as hard segments and hydroxy-terminated ethylene oxide-poly(dimethylsiloxa ...
Surface properties of the Ni-silica gel catalyst precursors for the vegetable oil hydrogenation process: N-2 sorption and XPS studies
(Maik Nauka/Interperiodica/Springer, New York, 2011)
The effect of the type of the silica gel pore structure on the surface properties of the Ni-silica gel catalyst precursors for the vegetable oil hydrogenation process has been examined applying N-2 sorption and X-ray ...
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 ...
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 ...
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 ...
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 ...
