Influence of oxyethylenated alkylamines in the dyeing of polyamide 66 fibres
(Elsevier Sci Ltd, Oxford, 2006)
This paper analyzes the influence of the chemical structure of a series of oxyethylenated laurylamines (LA-EO) on the formation of complexes with the dye C.I. Direct Red 1, as well as on the dyeing kinetics of the polyamide ...
Effect of temperature on the excess molar volumes of some alcohol plus aromatic mixtures and modelling by cubic EOS mixing rules
(Elsevier, 2006)
Densities of the (methanol + benzene), (ethanol + benzene), (methanol + chlorobenzene) and (ethanol + chlorobenzene) mixtures have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15 and 313.15 K) and ...
Determination of competitive adsorption isotherms applying the nonlinear frequency response method Part II. Experimental demonstration
(Elsevier, Amsterdam, 2009)
This paper demonstrates an experimental application of the nonlinear frequency response (FR) method extension to determine adsorption isotherms of binary mixtures. This method, based on the analysis of the response of a ...
The effect of mechanical activation on synthesis and properties of MgAl2O4 ceramics
(Elsevier Sci Ltd, Oxford, 2019)
Magnesium aluminate, MgAl2O4 and other alumina-based spinels are ceramics with high hardness, high melting point and mechanical strenght. Spinels can also be used as dielectrics in microwave applications. The goal of this ...
Efficiency of oil removal from real wastewater with different sorbent materials
(Elsevier Science Bv, Amsterdam, 2007)
The aim of this paper was to investigate the efficiency of different sorbent materials for oil removal from wastewater. Two types of sorbents were investigated: organic (loose natural wool fibers (NWF) and recycled wool ...
In situ stabilization of toxic metals in polluted soils using phosphates: theoretical prediction and experimental verification
(Elsevier, Amsterdam, 2005)
The in situ (in place) immobilization of toxic metals, using inexpensive "reactive" amendments, is considered as a simple and cost-effective approach for the treatment of soils, contaminated by the presence of heavy metals, ...
Prediction for debonding damage process and effective elastic properties of glass-bead-filled modified polyphenylene oxide
(Elsevier Sci Ltd, Oxford, 2006)
A three-dimensional three-phase finite element unit cell model has been applied to predict the debonding damage process of particulate polymer composites (PPC) during tensile deformation. The model consists of a particle, ...
Determination of thermal shock resistance of silicon carbide/cordierite composite material using nondestructive test methods
(Elsevier Sci Ltd, Oxford, 2008)
In the present work Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 30:70 and 50:50. Behavior of composite ceramics after thermal ...
Re-refining of waste mineral insulating oil by extraction with N-methyl-2-pyrrolidone
(Elsevier Science Bv, Amsterdam, 2006)
Extraction with N-methyl-2-pyrrolidone (NMP) via the three-stage mixer-settler operation was studied as possible process for re-refining of waste mineral insulating oil. The following extraction process parameters were ...
Osmotic and activity coefficients of {yNa(2)So(4)+ (1-y)ZnSO4}(aq) T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2005)
The osmotic coefficients of the mixed electrolyte solution {y Na2SO4 + (1 - y)ZnSO4} (aq) have been measured by the isopiestic method, at T = 298.5 K. The experimental results were treated by Scatchard's, Pitzer-Kim's and ...
