Self-association and association of tri-n-butyl phosphate (TBP) in different diluents
(Journal of the Serbian Chemical Society, 1999)
The interact ion of tri-n-butyl phosphate (TBP) with diluents and its self-association have been investigated. The corresponding equilibrium constants were determined and used to calculate the concentration of TBP monomer. ...
Real surface area of the aluminium electrode in sodium chloride solution
(Journal of the Serbian Chemical Society, 1999)
By combining the techniques of electrochemical slow potentiodynamic, AC impedance and atomic force microscopy (AFM), ii: was shown that the differences in the anodic dissolution rates of Al in 0.5 NaCl solutions as measured ...
An improved synthesis for obtaining 2-deoxy-2-iodo-D-mannopyranose derivatives
(Journal of the Serbian Chemical Society, 1998)
The aim of this work was to synthesize 2-deoxy-2-iodo-manno sugars and 2-deoxy-2-iodo manno esters of a satisfactory purity in the highest possible yield. For this put-pose, the iodination reaction of D-glucal triacetate ...
Conditioning of the filament for diamond deposition by hot-filament chemical vapour deposition method
(Journal of the Serbian Chemical Society, 1998)
A tungsten filament, 0.12 mm in diameter, was conditioned by heating in a mixture of methane and hydrogen of three different concentration ratios. The filament was heated by an electric current. The procedure was carried ...
Infrared spectra of uranyl compounds in alkali halide matrices: oxalates and acetates
(Journal of the Serbian Chemical Society, 1998)
The infrared absorption spectra of uranyl oxalate and acetate in KBr matrices in the 4000-250 cm(-1) range have been examined. Special attention was devoted to the dependence of the IR spetra on the sample treatment ...
Adsorption of boron containing molecules on silver nanoparticles
(Journal of the Serbian Chemical Society, 1998)
The effects of adsorption of boron containing molecules on the optical properties and reactivity of colloidal silver particles (4 nm diameter) were studied. The absorption spectra of silver particles surface modified by ...
Energetics of the ionization and fragmentation of sulfur-containing molecules studied by electron-impact spectroscopy. I. SO2F2
(Journal of the Serbian Chemical Society, 1998)
The positive ions produced by the dissociative ionization on SO2F2 were studied using a trochoidal electron monochromator as an electron Sun. The appearance energies of the fragment ions were measured and interpreted in ...
Preparation, crystal structure and antibacterial activity of condensation products of usnic acid and acyl hydrazides
(Journal of the Serbian Chemical Society, 1998)
Three condensation products of usnic acid with the hydrazides of α-naphthoic, caprylic, and oxamic acids, respectively, have been prepared and characterized by spectrometric methods. A reassignment of the 13C-NMR spectral ...
Thermodynamic consideration of the plasma process for boron nitride powder production from boric acid
(Journal of the Serbian Chemical Society, 1998)
The results of equilibrium composition and total enthalpy computation in the temperature range of 1000 to 6000 K and at pressure of 1 bar, for the systems B-O-H-N and B-O-C-H-N are presented in this paper. These data enable ...
Classification of the asphalts and their source rock from the Dead Sea Basin (Israel): the asphaltene/kerogen vanadyl porphyrins
(Journal of the Serbian Chemical Society, 1998)
The asphaltenes of the asphalts from the Dead Sea Basin were examined for the presence of vanadyl porphyrins. These examinations demonstrated that the asphalts fall into two broad class types, one having a relatively high ...
