Characterization and catalytic activity of poly(4-vinylpyridine-co- divinylbenzene)-Co2+ complex
(Materials Science Forum, 2005)
Poly(4-vinylpyridine-co-divinylbenzene)-Co2+ was characterized using infrared spectroscopy (IR), thermogravimetric analysis (TG-DTA), N 2-physisorption and polarography. Thermal analysis suggests sufficient thermal stability ...
Investigation of the interface states in the SiO2– Si system by photoacoustic method
(EDP Sciences, 2005)
The interface states in SiO2 - Si system was investigated by photoacoustic (PA) spectroscopy. The amplitude and phase spectra were measured and analyzed in dependence on the wavelength of excitation optical beam. In the ...
Biotransformation of nitric oxide in the cerebrospinal fluid of amyotrophic lateral sclerosis patients
(Maney Publishing, 2005)
Recent findings indicate that nitric oxide (NO•) over-production might be an important factor in thepathogenesis of sporadic amyotrophic lateral sclerosis (SALS). We measured significantly higherconcentrations ...
Formic acid oxidation on Pt/Ru nanoparticles: Temperature effects
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
The formic acid oxidation on Pt/Ru nanoparticles in acid solution over the temperature range 298-333 K has been studied by thin-film rotating disk method (RDE). Transmission electron microscopy in combination with scanning ...
Investigation of the effects of Ar plasma etching in Si surface by photoacoustic method
(EDP Sciences, 2005)
The effects of Ar plasma treatment on the Si surface were investigated by photoacoustic spectroscopy and atomic force microscopy. We studied the surface structure as a function of plasma experimental parameters to correlate ...
Photoacoustic investigations of thermal and electronic properties of single crystal Ge doped with Cr
(EDP Sciences, Les Ulis Cedex A, 2005)
A high purity single crystal Ge with a (1 1 1) orientation was doped with Cr. A thin film of Cr was evaporated and then diffused into Ge substrate. The photoacoustic PA amplitude and phase spectra were measured and numerically ...
Comparative potentiodynamic study of nickel and hydrogen underpotential deposition at polycrystalline platinum electrode in weak acid and neutral solutions
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
Underpotential deposition of nickel and hydrogen on polycrystalline platinum in weak acid and neutral solutions (3.5 LT = pH LT = 7.0), with and without Ni2+-ions, has been examined using cyclic voltammetric technique ...
The influence of acid treatment on the nanostructure and textural properties of bentonite clays
(Trans Tech Publications Ltd, Durnten-Zurich, 2005)
The nanostructure and textural properties of acid-activated bentonite clays from the Bogovina coalmine were investigated. The acid activation was performed with HCl in the concentration range 1.5-7.5 M. The atomic force ...
