Efficiency of membrane extraction of phenol-4-aminoantipyrine complex with n-alcohols
(Elsevier, Amsterdam, 2004)
In this study, the membrane extraction of phenol-4-aminoantipyrine complex with the series of aliphatic alcohols was investigated by monitoring the efficiency of the process. A commercial polysulphone hollow-fiber membrane ...
Characterization of microstructural changes in an Al-6.8 wt.% Mg alloy by electrical resistivity measurements
(Elsevier Science Sa, Lausanne, 2008)
Microstructural changes in an AlMg6.8 alloy after different thermo mechanical (TMT) and sensitization treatments were investigated by electrical resistivity measurements. The electrical resistivity was most affected by the ...
Thermal Properties of PMMA/TiO2 Nanocomposites Prepared by In-Situ Bulk Polymerization
(Wiley-Blackwell, Malden, 2009)
The surface of anatase TiO2 nanoparticles, obtained by the controlled hydrolysis of titanium tetrachloride, was modified by 6-palmitate ascorbic acid. The surface modified TiO2 nanoparticles were dispersed in methyl ...
Influence of cubic alpha-Fe2O3 particles on the thermal stability of poly(methyl methacrylate) synthesized by in situ bulk polymerization
(Elsevier Sci Ltd, Oxford, 2009)
Poly(methyl methacrylate)/alpha-Fe2O3 Composites were prepared by in situ bulk radical polymerization of methyl methacrylate in the presence of the cubic alpha-Fe2O3 particles using 2,2'-azobisisobutyronitrile as initiator. ...
Kinetics of the mild steel corrosion protection by polypyrrole-oxalate coating in sulfuric acid solution
(Elsevier Science Sa, Lausanne, 2006)
Kinetics of the mild steel corrosion protection in 0.1 mol dm(-3) H2SO4 by polypyrrole coatings have been investigated by the means of electrochemical impedance spectroscopy (EIS), cyclic voltammetry, polarization measurements ...
Phase transformation in cordierite gel synthesized by non-hydrolytic sol-gel route
(Elsevier Sci Ltd, Oxford, 2007)
Cordierite gel was synthesized by non-hydrolytic sol-gel route, starting from aluminum chloride, TEOS and magnesium chloride dissolved in absolute ethanol. Crystallization of p.-cordierite from gel at temperatures between ...
Plasma-induced Decolorization of Indigo-dyed Denim Fabrics Related to Mechanical Properties and Fiber Surface Morphology
(Sage Publications Ltd, London, 2009)
The aim of this study was to investigate how morphology of fibers is affected by plasma during the process of decolorization by a low-pressure RF plasma (gas, treatment time, and power were varied) and atmospheric pressure ...
Osmotic coefficient of the ZnCl2(aq) at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2003)
The osmotic coefficient of ZnCl2(aq) has been measured at T = 298.15 K by the isopiestic method over the range of molalities from (0.4 to 2.4) mol . kg(-1) with KCl(aq) as the reference solution. The available literature ...
Solids residence time distribution in gas-flowing solids-fixed bed contactors
(Amer Chemical Soc, Washington, 2005)
Flowing solids residence time distribution in gas-flowing solids-fixed bed contactors was investigated using a tracer technique with a step signal as input. Particles of different color (all other properties being the same) ...
