Characterization and catalytic activity of poly(4-vinylpyridine-co-divinylbenzene)-Co2+ complex
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
Poly(4-vinylpyridine-co-divinylbenzene)-Co2+ was characterized using infrared spectroscopy (IR), thermogravinietric analysis (TG-DTA), N-2-physisorption and polarography. Thermal analysis suggests sufficient thermal stability ...
Determination of all pK(a) values of some di- and tri-carboxylic unsaturated and epoxy acids and their polylinear correlation with the carboxylic group atomic charges
(Scientific Reviews Ltd., 2003)
For a series of seven unsaturated and seven epoxy di- and tricarboxylic acids, pK(a)(a) values were determined potentiometrically in aqueous media at 25 degreesC and an ionic strength of 0.1 M (NaCl). The thermodynamic ...
Study of supported Pt and PtRu catalysts in methanol and formic acid oxidation
(Trans Tech Publications Ltd, Switzerland, 2004)
The kinetics of methanol and formic acid oxidation on supported Pt and Pt2Ru3 catalysts are measured in 0.5 M H2SO4 at ambient temperature using thin-film rotating disc electrode (RDE) method. Both catalysts are characterized ...

Citrate-based zinc-polyaniline secondary cell: Part I: Optimization of the citrate/chloride electrolyte
(Journal of Applied Electrochemistry, 2009)
Electrochemical behavior of zinc and thin polyaniline (PANI) electrodes in citrate/chloride-contained electrolyte has been investigated by the means of electrolyte composition optimization. Electrolyte contained 0.8 M ...
Synthesis of mesoporous nanocrystalline titania powders by nonhydrolitic sol-gel method
(Academic Press Ltd- Elsevier Science Ltd, London, 2009)
Mesoporous titania with well-crystallized anatase phase was synthesized by nonhydrolytic sol-gel process combined with solvothermal treatment. Titanium-isopropoxide, titanium-tetrachloride, and carbon-tetrachloride were ...
Morphology and capacitive properties of [RuOxH y/low-surface area carbon black] composite materials prepared by sol-gel procedure
(Materials Science Forum, 2005)
The morphology and the capacitive properties of carbon supported hydrous ruthenium oxide (RuOxHy/C), prepared by impregnation of low-surface area carbon black Vulcan® XC-72 R with solid phase of RuO xHy sol, were investigated ...
D(2) dopaminergic and 5-HT(1A) serotonergic activity of 2-(1-naphthyl)ethyl- and 2-(2-naphthyl)ethyl amines
(Wiley-Blackwell, Malden, 2003)
Several tertiary 2-phenylethyl, 2-(1-naphthyl)ethyl and 2-(2-naphthyl)ethyl amines were synthesized and their binding affinities for dopamine D(1), D(2) and serotonin 5-HT(1A) receptors evaluated in radioligand binding ...
