Adsorption of methylene blue and methyl red dyes from aqueous solutions onto modified zeolites
(2013)Zeolite, hematite, modified zeolite and commercial activated charcoal were examined for their ability to remove methylene blue (MB) and methyl red (MR) from their aqueous solutions. Modified zeolite and hematite were ... -
Computer-aided estimation of acetone, methyl acetate, and chloroform diffusion coefficients in poly(vinyl acetate)
(2003)The diffusion coefficients of acetone, methyl acetate, and chloroform in amorphous poly(vinyl acetate) are estimated using the solvent evaporation method. The evaporation process from polymer solutions, cast in the form ... -
Computer-aided estimation of diffusion coefficients in non-solvent/polymer systems
(2001)Full Paper: A novel method for estimating the mutual and self-diffusion coefficients of a non-solvent/polymer system is proposed in this work. The idea is to stud the evaporation process from non-solvent/solvent/polymer ... -
Decolorization and degradation of reactive azo dyes via heterogeneous photocatalytic processes
(2010)Reactive dyes are extensively used in textile industry in the last years due to their superior performance, but they are environmentally hazardous and difficult to treat effectively by classical methods. In the present ... -
Decomposition of NH3 on Pd and Ir - Comparison with Pt and Rh
(1997)The unimolecular decompositions of NH3 on polycrystalline wires and foils of Pd and Ir are examined and compared with the corresponding ones on Pt and Ph. The reactions were carried out in a differential flow reactor, at ... -
Decomposition of NO on Pd and Ir. Comparison with Pt and Rh
(1996)The unimolecular decomposition of NO has been examined on Pd and Ir and they are compared with the corresponding reactions on Pt and Rh. The runs were carried out in a differential now reactor, at pressures from 0.01 to 5 ... -
Effects of B20 on the Operation of a Single-Cylinder Engine Equipped with a SiC Diesel Particulate Filter
(2014)This is an experimental and computational study of the effect of a low-percentage biodiesel blend on the operation, diesel filter loading, and fuel additive-assisted regeneration behavior on a conventional, direct injection ... -
Electrochemical removal of bromate from drinking water
(2013)The electrochemical removal of bromate on a tin cathode has been studied by both electrochemical techniques, such as cyclic voltammetry and chronoamperometry, as well as by steady-state electrolytic experiments. The reduction ... -
Modelling of microstructure evolution during precipitation processes: a population balance approach of the KWN model
(2006)In the present study a general kinetic model for phase transformations resulting in a second-phase particle precipitation in a matrix is presented. Such transformations involve simultaneous nucleation, growth and coarsening ... -
Nucleation, growth and detachment of neighboring bubbles over miniature heaters
(2008)This work investigates how simultaneous CO2 bubbles desorb from water and n-heptane when these liquids become supersaturated with dissolved CO2. Supersaturation is imposed locally by a miniature heater so bubbles grow at ... -
A parametric study of a solar calcinator using computational fluid dynamics
(2007)In this work a horizontal rotating solar calcinator is studied numerically using computational fluid dynamics. The specific solar reactor is a 10 kW model designed and used for efficiency studies. The numerical model is ... -
Phosphate Adsorption from Aqueous Solutions onto Goethite, Bentonite, and Bentonite-Goethite System
(2013)The present paper examines the phosphate adsorption from aqueous solutions onto goethite, bentonite, and bentonite-goethite system. The properties of the materials were studied by X-ray diffraction (XRD), attenuated total ... -
The Relation of the Vickers Hardness With the Loading Stiffness of Instrumented Vickers Indentation of Metal Substrates
(2010)The present paper presents a relation between the vickers hardness HV and the loading stiffness C of instrumented vickers indentation of metal substrates. The relation is based on the fact that the nonaxisymmetry of the ... -
A Semi-Empirical Model for the evolution of Retained Austenite via Bainitic Transformation in Multiphase TRIP Steels
(2008)Multiphase TRIP steels exhibit unique combinations of strength and cold formability, characteristics especially desirable in automotive applications. This behaviour is largely determined by the amount and stability of the ... -
Sorption of Cadmium and Arsenic by Goethite and Clinoptilolite
(2009)Cadmium (Cd) and arsenic (As) adsorption and desorption by goethite and clinoptilolite were the subjects of this article. Experimental variables were the concentrations of Cd, As, background electrolyte, and the solution ... -
Substrate specificity of guinea pig liver aldehyde oxidase and bovine milk xanthine oxidase for methyl- and nitrobenzaldehydes
(2006)Both aidehyde oxidase and xanthine oxidase catalyze the oxidation of a wide range of N-heterocycles and aldehydes. These enzymes are important in the oxidation of N-heterocyclic xenobiotics, whereas their role in the ...
