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 ...
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 ...
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 ...
Synthesis, characterization and antimicrobial activity of Ni(II) and Zn(II) complexes with N ',N '(2)-bis[(1E)-1-(2-pyridyl)ethylidene]propanedihydrazide. Crystal structures of two highly solvated bimetallic complexes of Ni(II)
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
The bimetallic [Ni-2(H(2)L2)(2)](ClO4)(4) (1), [Ni-2(HL2)(H(2)L2)](ClO4)(3) (2) and [Zn-2(H(2)L2)(2)](BF4)(4) (3) complexes (H(2)L2 = N',N'(2)-bis[(1E)-1-(2-pyridyl)ethylidene]propanedihydrazide) were synthesized and ...
Color changes of UHT milk during storage
(MDPI, BASEL, 2008)
In this study measurements of color parameters of UHT milk were performed, by using a MOM-color 100 photoelectric tristimulus colorimeter. Colors of UHT milk samples containing 3.2% and 1.6% milk fat, processed under ...
Sensory Properties and Color Measurements of Dietary Chocolates with Different Compositions During Storage for Up to 360 Days
(MDPI, BASEL, 2009)
In this work sensory characteristics (appearance - color, brilliance, shape and surface; texture - structure, break, firmness and chewiness; aroma - odor and taste) of dietary chocolates of different compositions were ...
Barium titanate screen-printed thick films
(Elsevier Sci Ltd, Oxford, 2002)
Barium titanate (BT) thick films were prepared from mechanically activated powders based on BaCO3 and TiO2. After homogenization and milling in a high-energy vibro mill, the powders were calcined at 700 degreesC for 2 h ...
Investigations of Bread Production with Postponed Staling Applying Instrumental Measurements of Bread Crumb Color
(MDPI, BASEL, 2009)
Crumb color quality characteristics of bread of different compositions (whole grain, rye, barley and diet bread) at 24 hours intervals during three days after bread preparation were investigated by means of a MOM-color 100 ...
