Morphology investigation of mechanically activated ZnO-SnO2 system
(Elsevier Sci Ltd, Oxford, 2008)
Powder mixtures of zinc oxide and tin oxide in the molar ratio, ZnO:SnO2 = 2: 1, were mechanically activated in a planetary ball mill in the time intervals of 0-160 min. The adsorption-desorption isotherms, specific surface ...
Transformation of petroleum saturated hydrocarbons during soil bioremediation experiments
(Water, Air, and Soil Pollution, 2008)
This paper presents transformations of saturated hydrocarbons of petroleum type pollutants during ex situ bioremediation of soil on the pilot heap (halde), during a period of 6 months, within the grounds of Petroleum ...
The mutual effect of extracellular Ca2+, abscisic acid, and pH on the rate of stomatal closure
(New York Acad Sciences, New York, 2005)
An analysis of the rate of stomatal closure in epidermal strips of Commelina communis L. induced by different calcium concentrations (10 nM to 1 mM) demonstrated a biphasic dependency, the initial process of closure being ...
Effects of the acrylic polyol structure and the selectivity of the employed catalyst on the performance of two-component aqueous polyurethane coatings
(MDPI, BASEL, 2007)
Two kinds of aqueous acrylic polyols (single step and multi step synthesis type) have been investigated for their performance in the two-component aqueous polyurethane application, by using more selective catalysts. The ...
SDS-PAGE analysis of soluble proteins in reconstituted milk exposed to different heat treatments
(MDPI, BASEL, 2007)
This paper deals with the investigation of the impact of the heat treatment of reconstituted skim milk conducted at different temperatures, and the adding of demineralized whey on the protein solubility, soluble protein ...
Spectroscopic characteristics of highly selective manganese catalysis in acqueous polyurethane systems
(MDPI, BASEL, 2006)
The latest investigations on producing more efficient catalytic aqueous polyurethane systems are in the domain of metal complexes with mixed ligands. In our previous research works, the high selectivity for the isocyanate-hydroxyl ...
Identification of metals (heavy and radioactive) in drinking water by an indirect analysis method based on scale tests
(MDPI, BASEL, 2008)
The analysis of water quality, regarding the content of metals, especially heavy and radioactive ones, has been carried out in an indirect way, by testing scale formed in a hot-water heater, using water from the water-supply ...
Thermal stability of aqueous polyurethanes depending on the applied catalysts
(MDPI, BASEL, 2006)
The thermal stability of aqueous polyurethanes has been measured applying the thermogravimetric analysis. The aqueous polyurethanes (aqPUR) with catalysts of different selectivity have been studied by use of the dynamic ...
