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 ...
Mechanically activated synthesis of CaTiO3 from mixture of CaO and TiO2
(Materials Science Forum, 2005)
Crystalline calcium titanate was synthesized by mechanical activation of a mixture of CaO, obtained by thermal treatment of CaCO3, and TiO 2 in anatase or rutile form, in a planetary ball mill for 30, 60, 120 and 240 min.. ...
Covalent modification of hexokinase by biologically active quinones
(Oxford : Blackwell Publishing, 2005)
In this work, inhibition of sulfhydryl containing glycolytic enzyme hexokinase by avarone and its derivatives was studied. The enzyme contains lysine and sulfhydryl residues, which can be modified by the quinone moiety. ...
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 ...
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 ...

Nano Design of Biphasic ciumphosphate/Poly-Dl-Lactide- Co-Glycolide, as Composite Biomaterials for Hard Tissue Reconstruction
(2005)
Poster presented at the The Seventh Yugoslav Materials Research Society Conference - YUCOMAT 2005, Herceg Novi, Montenegro, September 12-16, 2005.
Microstrip attenuator on silicon substrate with a compact EBG (or PBG) cell
(Telsiks 2005, Proceedings, Vols 1 and 2, 2005)
In this paper a new type of lambda/4 attenuator on silicon substrate is simulated, fabricated and measured. A lambda/4 open microstrip stub is realized as an EBG (or PBG) cell. Reduction of the central attenuator frequency ...
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 ...
Светлина и хармонија / Light and Harmony
(Skopje: Mathematical Society of Macedonia, 2005)
Светлината како појава или причина, интригира со својата дуална браново-корпускуларна природа. Во многу ситуации, посебно кога доаѓа до размена на енергијата, доминира природата на честичка, а во ситуациите на интеракција ...
