Volumetric properties of the ternary system ethanol plus 2-butanone plus benzene by the van der Waals and Twa-Coon-Bluck-Tilton mixing rules: experimental data, correlation and prediction
(Elsevier, Amsterdam, 2004)
Densities of the ternary system ethanol + 2-butanone + benzene and its binaries ethanol + 2-butanone, ethanol + benzene and 2-butanone + benzene were measured at T = 298.15 K and atmospheric pressure. From these densities ...
Nanostructured sodium niobate obtained by glass crystallization
(Elsevier Science Sa, Lausanne, 2004)
The subject of this work was to obtain nanostructured sodium niobate crystals by a controlled crystallization method from glasses. The glass samples of the composition within the system NaNbO3-SiO2-Al2O3 were prepared by ...
Methyl methacrylate and acrylamide crosslinked macroporous copolymers
(Journal of Applied Polymer Science, 2004)
In this work the synthesis of a crosslinked macroporous copolymer was effected from methyl methacrylate and acrylamide. The synthesis process began with emulsion prepolymerization, followed by sol-gel copolymerization until ...
Mechanochemical synthesis of gamma-Bi2O3
(Amsterdam : Elsevier, 2004)
A series of gamma-Bi2O3 phases doped with Zn, Si, Pb and Fe was prepared by mechanochemical treatment of corresponding oxide mixtures with a nominal composition 6Bi(2)O(3) (.) MOx (MOx = ZnO, SiO2, PbO) and 12Bi(2)O(3) (.) ...
Dielectric and piezoelectric properties of the mechanochemically prepared PZT ceramics
(Kluwer Academic Publishers, 2004)
Mechanochemical synthesis was applied to obtain nanocrystalline powders of composition Pb(Zr0.52Ti0.48)O-3 (PZT). Milling was performed in a planetary ball mill using vials and balls made of zirconia or steel-in order to ...
Support of laboratory accreditation in Central and Eastern Europe by preliminary assessment
(Springer-Verlag, 2004)
The development of a competent and reliable network of accredited laboratories represents one, among other, important means of removal of technical barriers to trade. The achievement of the goal "tested once-accepted ...
Structural analysis of abrasive composite materials with nonwoven textile matrix
(Elsevier B.V., 2004)
The goal of this research was to design the novel composite material based on nonwoven textile material (NTM) while using the existing production facilities. The chosen product was abrasive composite material with nonwoven ...
Electrocatalytic behaviour of MoPt3 intermetallic phase for hydrogen evolution in acid solution
(Ecole Polytechnique de Montreal, 2004)
Metallurgicaly prepared MoPt3 intermetallic compound has been investigated as electrocatalyst for the cathodic evolution of hydrogen (HER) in 0.5 mol dm-3 HClO4 solution at 298 K. The HER on activated and non-activated ...
