Some problems connected with boron determination by atomic absorption spectroscopy and the sensitivity improvement
(Journal of the Serbian Chemical Society, 2001)
Two atomizers were compared: an N2O-C2H2 flame and a stabilized U-shaped DC arc with aerosol supply. Both the high plasma temperature and the reducing atmosphere obtained by acetylene addition to the argon stream substantially ...
Facile synthesis of water-soluble curcumin nanocrystals
(Journal of the Serbian Chemical Society, 2015)
In this paper, a facile synthesis of water-soluble curcumin nanocrystals is reported. Solvent exchange method was applied to synthesize curcumin nanocrystals. Different techniques were used to characterize the structural ...
Effects of low gamma irradiation dose on the photoluminescence properties of graphene quantum dots
(Springer, 2016)
We prepared graphene quantum dots (GQDs) using electrochemical approach. The luminescent properties of GQDs at various excitation wavelengths are examined. In order to study the possibility to improve these properties, we ...
Raman spectroscopy study of graphene thin films synthesized from solid precursor
(Optical and Quantum Electronics, 2016)
In this work, we present Raman spectroscopy study of graphene thin films obtained by rapid thermal annealing in vacuum. As a carbon source, we used spectroscopic graphite electrodes cut into small pieces on top of which ...
Experimental study of physical parameters significant in fullerene synthesis
(Journal of the Serbian Chemical Society, 2003)
In this work, the effect of physical parameters on the yield of fullerene, synthesized in a hollow cathode plasma reactor is investigated. The experimental investigations done previously have shown that the fullerene yield ...
Optical diagnostics of fullerene synthesis in the RF thermal plasma process
(Journal of the Serbian Chemical Society, 2005)
In this work, the results of an optical emission study of fullerene synthesis in an inductively coupled radio frequency thermal plasma reactor are presented. The emission spectroscopy studies, based on the use of the Swan ...
Multiple charged nitrogen ion beam irradiation of fullerene thin films
(Fullerenes Nanotubes and Carbon Nanostructures, 2007)
In this work, the results of structural modification of fullerene thin films bombarded by multiple charged nitrogen ions have been reported. The properties of as-deposited and irraditated fullerene thin films have been ...
Optical emission study of RF thermal plasma during fullerene synthesis
(Fullerenes Nanotubes and Carbon Nanostructures, 2005)
Results on studies of molecular spectra emitted in the initial stages of fullerene synthesis during processing of graphite powder in RF thermal plasma conditions are presented in this work. CN-usually present in carbon ...
Synthesis and crystal structure of 1,2,3,4-tetrahydro-9-aminoacridine tetrachlorozincate(II) monohydrate / Sinteza i kristalna struktura 1,2,3,4-tetrahidro-9-aminoakridin-tetrahlorocinkata(II) monohidrata
(Journal of the Serbian Chemical Society, 2010)
In the reaction of ZnCl(2) with tacrine hydrochloride in water novel tetracoordinated (C(13)H(15)N(2))(2)[ZnCl(4)]-H(2)O complex was obtained and characterized by elemental analysis, molar conductivity and X-ray analysis. ...
High dose of ethanol decreases total spectral power density in seizures induced by D,L-homocysteine thiolactone in adult rats
(General Physiology and Biophysics, 2009)
The effects of ethanol on epilepsy are very complex. Ethanol can have depressant as well as excitatory effect on different animal models of epilepsy. Systemic administration of homocysteine can trigger seizures. The aim ...
