Chitosan/acid dye interactions in wool dyeing system
(Elsevier Sci Ltd, Oxford, 2005)
This study assesses the interactions that could occur during dyeing of the chitosan treated wool fibres on basis of the spectrophotometric study, by measuring the absorbance values of the solutions containing dye and ...
Electrochemical deposition and corrosion stability of Zn-Co alloy coatings / Elektrohemijsko taloženje i koroziona stabilnost prevlaka Zn-Co legura
(Engineering Society for Corrosion, Belgrade, Serbia, 2006)
The influence of the type of the deposition solution, deposition current density and temperature of deposition solution on the phase structure and corrosion properties of Zn-Co alloys was examined. Alloys were deposited ...
Corrosion stability of epoxy coatings on aluminum pretreated by vinyltriethoxysilane
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The electrochemical and transport properties and adhesion of epoxy coatings electrodeposited on aluminum pretreated by vinyltriethoxysilane (VTES) were investigated during exposure to 3% NaCl. The VTES films were deposited ...
Removal of heavy metal ions from water by complexation-assisted ultrafiltration
(Pergamon-Elsevier Science Ltd, Oxford, 2006)
Toxic heavy metals in air, soil and water are global problems that are growing threat to the environment. Therefore, the removal and separation of toxic and environmentally relevant heavy metal ions are a technological ...
Electrochemical synthesis and characterization of hydroxyapatite powders
(Elsevier Science Sa, Lausanne, 2008)
Electrochemical synthesis of hydroxyapatite powders was performed galvanostatically from homogeneous solution of Na(2)H(2)EDTA center dot 2H(2)O, NaH2PO4 and CaCl2 at a concentration relationship Ca/EDTA/PO43- of 0.25/0.25/0.15 ...
Influence of composition of the magnetic composite coating on the performance of the optical fiber magnetic field sensing element
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
The optical fiber magnetic sensing element (OFMSE) based on the optical fiber coated with composite coating polymermagnetic powder has been already introduced in magnetic field sensing. In this research, the rapid quenched ...
The ultrasonic and image analysis method for non-destructive quantification of the thermal shock damage in refractory specimens
(Elsevier Sci Ltd, Oxford, 2009)
In the present work, Mg-exchanged zeolit and silicon carbide were used as starting materials for obtaining cordierite/SiC composite ceramics with weight ratio 50:50. Samples were exposed to the water quench test from 950 ...
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 ...
XPS and contact angle study of cotton surface oxidation by catalytic bleaching
(Elsevier Science Bv, Amsterdam, 2007)
Surface chemistry and wetting properties of cotton fibres as affected by catalytic bleaching have been investigated. Two types of cotton fabric have been analysed: the regular and a model cotton fabric. In the regular - ...
Combustion of Metallurgical Wastes Using Secondary Aluminum Foils
(Taylor & Francis Inc, Philadelphia, 2017)
Simulating the reactions in a complex system can lead to self-sustaining and energy efficient treatment of wastes in recycling promoting manner. In this contribution, the synergic combination of electric arc furnace dust ...
