The effect of the presence of alcohol in the dispersing phase of oxide sols on the properties of RuO2-TiO2/Ti anodes obtained by the sol-gel procedure
(Journal of the Serbian Chemical Society, 2000)
The effect of the addition of ethanol and 2-propanol to the dispersing phase of TiO2 and RuO2 sols mixture on the morphology and, consequently, on the electrochemical properties of the sol-gel obtained activated titanium ...
Air oxidation of the kerogen/asphaltene vanadyl porphyrins: an electron spin resonance study
(Journal of the Serbian Chemical Society, 2000)
The thermal behavior of vanadyl porphyrins was studied by electron spin resonance during heating of kerogens, isolated from the La Luna (Venezuela) anti Serpiano (Switzerland) bituminous rocks, at 250 degrees C for 1 to ...
Influence of negative charge on the optical properties of a silver sol
(Journal of the Serbian Chemical Society, 2000)
The effects of negative charge on the optical properties of a silver sol prepared using sodium borohydride as a rcductant were studied. The oscillations ill the position of the maximum and the intensity of the surface ...
Spectrophotometric investigations of the reaction between gold(III) and potassium iodide
(Journal of the Serbian Chemical Society, 2000)
The equilibria of the complex formation between AuCl4-n(OH)(n)(-) and I- was studied spectrophotometrically in aqueous solutions containing KI:Au(III)less than or equal to 2 in the acidity range from 1 M HCl to pH 7 at 25 ...
Structural modifications of Cu(II) 12-tungstophosphoric acid salit studied by IR and Raman spectroscopy
(Journal of the Serbian Chemical Society, 2000)
In this paper local processes and structural phase transformations of the copper salt of 12-tungstophosphoric acid are investigated. The structural phase transformations were followed through bands, characteristic for the ...
An attemp to use a pulsed CO2 laser for decontamination of radioactive metal surfaces
(Journal of the Serbian Chemical Society, 2000)
There is a growing interest in laser radioactive decontamination of metal surfaces. It offers advantages over conventional methods: improved safety, reduction of secondary waste, reduced waste volume, acceptable cost. The ...
Modification of the aluminum for making offset printing plates
(Journal of the Serbian Chemical Society, 2000)
Aluminum as the base of offset printing plates should make good contact with wetting agents and the light sensitive layer and should be resistant to wear and cracking. In order to achieve this, the aluminum is roughened ...
A simplified approach to the vibrational self-relaxation of simple molecules through convolution of their velocities
(Journal of the Serbian Chemical Society, 2000)
A theoretical approach has been developed for computing collisional self-relaxation probabilities of the first excited level in the lowest vibrational mode of simple molecules. The bending (nu(2)) vibration in triatomic ...
A frequency stabilized waveguide CO2-laser for photoacoustic spectroscopy of gases
(Journal of the Serbian Chemical Society, 2000)
A theoretical model of a waveguide CO2-laser was made to optimize the dimensions of the waveguide tube and resonator, i.e., to obtain the best mode structure while maximizing the output power. The results were used to ...
Determination of the critical molar mass of ovalbumin oligomers degraded by ultrasound
(Journal of the Serbian Chemical Society, 2000)
An experimental method has been developed which enables the determination of the critical molar mass (Mmc) of ovalbumin oligomers degraded by ultrasound of known frequency. To test the validity of the Mmc postulate, a ...
