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 ...
Removal of volatile organic compounds from activated carbon by thermal Desorption and catalytic combustion
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The thermal desorption of saturated activated carbon discharged from an industrial adsorber and catalytic oxidation of desorbed products over a Pt/Al2O3 catalyst were investigated. The activated carbon is almost completely ...
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 ...
Chemical and radiochemical characterization of depleted uranium in contaminated soils
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The main results of chemical and radiochemical characterization and fractionation of depleted uranium in soils contaminated during the Balkan conflict in 1999 are presented in the paper. Alpha-spectrometric analysis of ...
Thin layer of Ni-modified 13X zeolite on glassy carbon support as an electrode material in aqueous solutions
(Maik Nauka/Interperiodica/Springer, New York, 2007)
A new type of an electrode material, zeolite modified by the incorporation of Ni or NiO clusters into its cavities, was synthesized by multiple impregnation of zeolite 13X with a Ni-acetylacetonate solution followed by ...
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 ...
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 ...
Structural and textural properties of Al,Fe-pillared clay catalysts
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Metal oxide pillared interlayered clays (PILCs) represent a new class of materials that have found a wide range of potential applications including catalytic oxidative degradation of organic pollutants in water. Al,Fe-pillared ...
beta-Carotene removal from soybean oil with smectite clay using central composite design
(Maik Nauka/Interperiodica/Springer, New York, 2009)
In this study removal of beta-carotene from soybean oil by adsorption on acid activated smectite clay from Serbia was investigated and a factorial 2(3) experimental design was applied. The effects of relevant factors, such ...
Oxidation of formic acid on platinum surfaces decorated with cobalt(III) macrocyclic complexes
(Maik Nauka/Interperiodica/Springer, New York, 2009)
Platinum electrode decorated with three different mixed-ligand cobalt(III) complexes of the general formula [Co(Rdtc)cyclam](ClO4)(2) [cyclam = 1,4,8,11-tetraazacyclotetradecane, Rdtc(-) = morpholine-(Morphdtc), ...
