Structural - Phase transformations in bentonite after NaOH-BaCl2 treatment in conditions of water deficiency
(Silicates Industriels, 2006)
The methods of X-ray diffraction, FTIR-spectroscopy, electron microscopy, X-ray microanalysis and others were used for investigation of structural phase reorganization, which occurs in a montmorillonite-gypsum mixture ...
Phenolics, lignin content and peroxidase activity in Picea omorika lines
(Acad Sciences Czech Republic, Inst Experimental Botany, Praha 6, 2006)
We analyzed low molecular mass phenolics, lignin content and both soluble and cell wall bound peroxidase activity in the needles of three Picea omorika (Pancic) Purkyne lines grown in the generative seed orchard. The highest ...
Monosaccharide-H2O2 reactions as a source of glycolate and their stimulation by hydroxyl radicals
(Elsevier Sci Ltd, Oxford, 2006)
An analysis of the H2O2-induced breakdown and transformation of different keto-monosaccharides at physiological concentrations reveals that glycolate and other short-chained carbohydrates and organic acids are produced. ...
Modification of the structural and optical properties of commercial ZnO powder by mechanical activation
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2006)
Mechanical activation was used as a method for modification of the structural and optical properties of commercial ZnO powder. For this purpose zinc oxide powder was mechanically treated by grinding in a high-energy ...
Thermal diffusivity and electron transport properties of NTC samples obtained by the photoacoustic method
(Elsevier Science Sa, Lausanne, 2006)
Thermal diffusivity and electron transport parameters of sintered NTC samples were determined by the photoacoustic (PA) technique. Powder mixtures composed of MnO, NiO, CoO and Fe2O3 were milled to nanometer particle size. ...
COMPARISON OF DIFFERENT MATHEMATICAL MODELS IN DECONVOLUTION OF LIGNIN FLUORESCENCE SPECTRA
(Society of Physical Chemists of Serbia, 2006)
We analysed fluorescence spectra of poplar lignin and lignin model compound, using
gaussian, log-normal and exponential power model. Asymmetric models show wavelength
positions of components in a complex molecule. Gaussian ...
EFFECT OF POWDER SYNTHESIS ON CRYSTAL AND MICROSTRUCTURE OF BaTiO3
(COST Action 539 - ELENA 2'd Workshop, Brussels, November 15-16, 2006, 2006)
Barium titanate (BaTiO3) has been used in many applications such as multilayer
capacitors, piezoelectric ceramics, transducer devices, PTC resistor and has become one of
the most important ferroelectric ceramics. It is ...
Trovanje kamforom - spektralna analiza aktivnosti mozga pacova / Camphor oil poisoning: Spectral analysis of rat brain activity
(Serbian Union of Biological Sciences, 2006)
We have decided to detect the seizure brain activity induced by camphor essential oil in rats, as there are still reports of severe intoxication in humans by camphor. The experiments were performed on adult Wistar male ...
Multiple forms of superoxide dismutase in the apoplast and whole-needle extract of Serbian spruce [Picea omorika (Panč.) Purkyně]
(Serbian Biological Society, 2006)
Activity and isoenzyme composition of superoxide dismutase in the apoplast and whole-needle extract of Picea omorika (Panč.) Purkyně, was studied. Total SOD activity of the soluble fraction of the needle extract exceeded ...
