Doped gamma-Bi2O3: synthesis of microcrystalline samples and crystal chemical analysis of structural data
(Walter de Gruyter Gmbh, Berlin, 2007)
A series of microcrystalline products containing the gamma-Bi2O3 phase doped with Co, Fe, Mn, Pb, Sb, Si, Ti, V and Zn has been prepared by solid state reaction. Based on the heating temperature and heating time, the ...
Adsorption of phenol and 2,4-dinitrophenol on activated carbon cloth: The influence of sorbent surface acidity and pH
(Taylor & Francis Inc, Philadelphia, 2006)
In this work the effect of the activated carbon cloth surface acidity and pH of the solution on phenols adsorption has been studied. Two phenols, widely different in the terms of their pKa values (phenol and 2,4-dinitrophenol), ...
The study of corrosion stability of organic epoxy protective coatings on aluminium and modified aluminium surfaces
(Soc Brasileira Quimica, Sao Paulo, 2005)
Epoxy coatings were formed by cathodic electrodeposition of an epoxy resin on aluminium and modified aluminium surfaces (phosphatized, chromatized-phosphatized and anodized aluminium) using a constant voltage method (resin ...

Trace elements analysis of Echinacea purpurea - herbal medicinal
(Elsevier, Amsterdam, 2003)
Elemental composition of Echinacea purpurea (Asteracae), grown in Serbia under strongly controlled conditions, has been studied. To distinguish elemental patterns of different parts of the plant, the content of Zn, Fe, Cu, ...
Enhancement of the electrochemical reduction of oxygen at platinum by nickel underpotential deposition
(Springer, New York, 2006)
Polycrystalline Pt electrode was modified by underpotential deposition (upd) of nickel. The modification was performed by potential cycling in phosphate buffer pH 7. 0 containing NiSO4, in which hydrogen and nickel upd ...
Surface properties of HAP particles obtained by hydrothermal decomposition of urea and calcium-EDTA chelates
(Proceedings of the 15th International Symposium on Ceramics in Medicine; The Annual Meeting of the International Society for Ceramics in Medicine, 2003)
In this paper surface properties of calcium-hydroxyapatite, synthesized by modified hydrothermal reaction of urea and Ca(EDTA)(2-) in phosphate solutions, as well as the dependence of calcium hydroxyapatite dispersion ...
Threshold voltage in MOSFETs and MODFETs as a problem of nonlinear dynamics
(Natl Inst Optoelectronics, Bucharest-Magurele, 2007)
A widely known (and also very well examined) problem of threshold voltage in MOSFETs and MODFETs has been described with the tools of nonlinear dynamics. Some interesting features of such devices have been derived, together ...
Temperature dependence of densities and excess molar volumes of the ternary mixture (1-butanol plus chloroform plus benzene) and its binary constituents (1-butanol plus chloroform and 1-butanol plus benzene)
(Springer/Plenum Publishers, New York, 2008)
Densities rho of the 1-butanol + chloroform + benzene ternary mixture and the 1-butanol + chloroform and 1-butanol + benzene binaries have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, and ...
